HWBB-001155*! HHBB-0011555 FOUNDATION FACTS Foundation Facts is a monthly newsletter issued to industrial concerns holding membership in Industrial Hygiene Foundation. The Foundation is a non-profit association of industries for the advancement of healthful working conditions. Vol. 7 December. 19A5 No. 12 X-Rav Diffraction Laboratory Established Announcement is made of the establishment of a Department of Research in Chemical Physics at Mellon Institute which will be available to Industrial Hygiene Foundation and further augment the Foundations services to member companies in maintaining good physical working conditions. This new division includes x-ray diffraction equipment which is essential for the accurate evaluation of factory dusts inasmuch as this method is more dependable than the older chemical or petro graphic methods. Dr. Harold P, Klug, formerly of the University of Minnesota, heads the new department and will serve as a consultant to the Foundation. The U--li new laboratory is located on the same floor as the Foundation in the Institute.. The availability of facilities for x-ray diffraction analyses is another important development in the Foundation's work of refining the measurement of dust hazards in the workplace. The I-H-F Composition Sampler permits the Staff to rapidly collect large-dust samples from factory air for composition analyses. All dust samples are separated into portions above and below five ailerons to gain more accurate knowledge of the concentration which workmen may actually ofeathe. Coming Publications The Transactions of the Management Section of the program fop the Tenth Annual Meeting will be sent to member companies in- the near future. Practically all the papers presented at the atmarai meeting are now set in type and the pro ceedings, in four parts, will be published as rapidly as possible. The Management Section will be followed by the Veterans Panel discussion. Meanwhile, a summary Covering highlights of the Engineering, Conference, held here on November 13, the day prior to ther opening of the annual sleeting, will be sent to member companies in a few days. Tnrinfl-hr^al Health Codes -I The Ohio State Health Department recently announced a proposed code oh- industrial health and toxicity which contains "maximum allowable concentrations0 for a long -list of gases, vapors, dusts and fumes. Copies of the proposed bode are available to Members upon request. A somewhat similar code' was recently adopted in Oregon and such regulations are under consideration or have been recently enacted ir. several other States. . Trustees Meeting: A meeting of the Foundation's Board of Trustees will be held late in January. ' 03118576 INDUSTRIAL HYOIENE FOUNDATION .400 FIFTH AVENUE PITTSSUROH (l). FA.

W. BROUN (UC) DSN (at opening of Tenth Annual Meeting at Mellon Institute, Pittsburgh, Pa*, Not* 15, 1945) 00 c=a It is with distinct pleasure that I come here this morning on behalf of the Navy to present the award of the Certificate of Achievement for war services to the Industrial Hygiene Foundation of America* . I will refer briefly at this point to the significance of this award in re lation to the Army and Navy "" The latter was granted to certain companies which produced certain end products of direct naval or military application, such as parts of naval guns, torpedoes, and fire control equipment* There are, however, a number of principal and subcontractors, who were not eligible for the Army and Navy *", and yet merit recognition for the high quality and quantity of their output in support of the war production program* The Navy, therefore, decided to award the Certificate of Achievement to these organizations, and the Industrial Hygiene Foundation of America was nominated for this honor by the* Surgeon General of the Navy* 03118577 HWBB-0011557 Presentation of Certificate of Achievement - 2 May I point out that this award is unique in that it is being conferred upon an organization notable for its efforts in promoting the conservation of indus trial personnel, a factor so closely geared to war production. In production we tend to think in terms of the finished implements of war without sufficient emphasis on the significance of saving manpower by the safeguarding of industrial health. The Navy brings this award this morning to an organization of outstanding excellence in this phase of the war effort. The primary objective of industrial hygiene is the maintenance of indus trial manpower through the prevention of industrial illness and accident. Your ability as an organization to advance industrial health has been attained by the excellence of your surveys of occupational hazards, thereby improving working con ditions in war plants; by studies of health conditions of women in industry - a new problem; and by your important publications, notably the Industrial Hygiene Digest the only journal of its kind. The Medical Department of the Navy has a traditional motto expressive of its primary military mission; viz, "To keep as many men at as many guns as many days as possible". One could fittingly paraphrase these words to express the war objec tive of your organization; as follows, "To keep as many men and women at as many industrial machines as many days as possible". The services to your industrial member companies not only reduced absen teeism incident to industrial illness, but increased personnel efficiency as a result of improved environmental conditions. This reflects distinct credit on your techni cal staff. In recognition of your war service and in token of appreciation of the Navy, it is my privilege to present to the Industrial Hygiene Foundation of America this Certificate of Achievement. This is the Navy* s whole hearted way of saying "Well done". E. W.

The Yale School of Medicine recently announced plans for an Institute of Occupational Medicine and Hygiene, in which specialists may be trained in the diagnosis and treatment of specific occupational diseases, and general practi tioners of medicine may study the background of the workers' conditions. Undergraduate medical students will receive training throughout all four years of their course and the curriculum will include such fields as sanitation; toxicology; surgery for wounds; injury and shock; rehabilitation methods; industrial medicine; problems of ventilation; industrial medical administration, etc. Graduate training will also be available for industrial nurses. The . Institute proposes to carry on research on basic problems and to provide con sultation services. Funds to carry on this work should come from the indus tries. -- Conn. Health Bull.

The possibility that organic chemists might suffer blood damage in the course of their r.dvrjiced studies and university research work was disclosed in a com munication from the Ohio Industrial Hygiene Service to the Industrial Hygiene Division, D.S. Public Heclth Service,*in which it was reported that a number of organic research chemists in a large pharmaceutical laboratory hove sus tained such injury. Witii a white blood cell count of 5,000 established arbi trarily as the critical level, it was found that five out of ?. staff of 20 chemists, all holding doctorate degrees and some with several years of post doctorate research experience, showed a level below that figure in periodic physical examinations. The red cell count remained normal. As a result of these findings the company plans to include a blood analysis in its preplace ment examination of chemists, to improve ventilation and install other safe guards in the research laboratories and to keep the condition of the men under close observation. It is pointed out that the problem may be originating in the reseirch laboratories of some universities and that thorough preplccement physical examinations may bar from employment chemists whose blood condition is poor. -- Ind. Hyg. News Letter, 5, 2 (Oct., 1945) 1209 Join the ftavy_j:nd Eat Penicillin Ice Cream.

The Division of Industrial Hygiene, Baltimore City Health Department, is making a study of the health hazards involved in the large-scale removal of blackout paint. Since scraping is not a feasible method for removal, chemical solvents must be used. One group of paint solvents contains alkalis which produce der matitis upon contact with the skin, and another group contains volatile chemi cals, chiefly benzol, alcohol, and methylene chloride, which may result in various types of physical damage. Kecommendations to protect the health of ex posed workers include protective garments, frequent determination of the atmos pheric concentration of toxic materials, and medical control through periodic examination of urine for sulfate ratios and of blood for both white and red cell counts. -- Safety Eng., 90, 113 (Oct., 1945) 1211 Need .for Campaign to Recruit Industrial Hygienists. Shortage of professional personnel is felt acutely by all industrial hygiene agencies. With the break in training of young men due to the war, the shortage is becoming particularly severe. One way by which it may be overcome is pointed out by Medical Director J.G.. Townsend, Chief of the Industrial Hygiene Division, U.S. Public Health Service. He urges that State and. local directors of indus trial hygiene units, make a determined effort to interest students in the profes sion. Lectures should be arranged and given to classes in medical schools, colleges of engineering and university scientific departments. The attractive opportunities available to industrial hygienists in the service of American in dustries or public health agencies should be set before students of chemistry, dentistry, nursing, and other professions associated with industrial health activities. In personal letters to deens of such colleges, training opportuni ties in the various fields of industrial, hygiene may be explained. If indus trial hygiene is to expand its activities to protect all industrial workers in the United States, many more men and women must be trained for all the contri buting professions. --Ind. Hyg.

The 'uthor discusses the manner in which an employer may safely permit the use of industrial medical records in his possession. A record can be made available on the request of the worker, in his interest, or by the employer to defend himself against the claims of the worker. This then would seem to eliminate the use of the records of a group of employees as a basis for sta tistical study or clinical investigation (except in reports required by law, as communicable diseases). However, the author feels that such use should be permitted, if the identity of individual employees is in no way revealed. Access to the medical records of an employee should be granted to his attend ing physician. -- T.7. McDavitt. Am, J. Pub.

Filed Novem ber 20, 1945 (CCH) 1216 Scone of Authority of Texas_Board of Insurance Commissioners to Control Opera tions of. Insurance. Carriers. Plaintiff association brought an action to enjoin the enforcement of and to test the validity of an order of defendant Board on the ground that said order exceeded the statutory powers granted to said Board. By means of the order, the Board sought to control dividends in complete detail in advance, on the ground that distribution of such dividends might affect the premium rate, by forbidding the writing of any compensation insurance by a participating com pany unless such dividend plan had been submitted to and approved by the -Board. However, the order set fortii no standard by which the Board was to be guided in either approving or disapproving the conditions on which a company would be permitted to write workmen1 s compensation insurance. A temporary C=0 injunction was granted by the trial court with certain limitations, namely, that the Board was not thereby prohibited from exercising its statutory powers to m^ke and enforce classifications of hazards and premium rates ap plicable to each class, to enforce a system of experience rating, or to re quire adequate reserves before approving an application for the payment of a 03118583 T)MBB-0011563 Industrial Hygiene Digest - 5 December, 1945 sum out of surplus for dividend distribution. The reviewing court affirmed, ruling that plaintiff was created by the workmen's compensation statute and was given authority to group subscribers based on premium (fixed by the Board and loss experience, and to fix ana pay dividends by and for groups. No such power was expressly granted to the Board. While the Board is required to ap prove dividends proposed before they can be paid, the statute fixes the stan dard by which approval or disapproval must be made, namely that such dividend must not reduce the association's reserves below what the Board deems to be adequate to meet losses end claims. But that is the extent of the Board's piwer in this regard, and it was without authority to regulate* dividends as attempted in the order in question. -- Board of Insurance Commissioners v.

Radiol., 18. 126-131 (Apr., 1945) This is a technical discussion of the procedure methods used in measuring redio-active material under various circumstances. The safe level for active material (radon gas) in the atanosphere was determined to be 10-1^ curie per liter of air. The level can usually be kept beneath this figure by exhaust ventilation. Measuring the amount of radium within, the body is of great impor tance in deciding whether on individual should continue work. This should in clude (a) measurement of concentration in expired air after the subject has breathed normal air for some time. The tolerance value given is 10-12 curie per liter, (b) direct gamma-ray measurement of the subject's body. The toler ance value here is given as 0.1 microgram of radium in the body. The investi gators found that most factories are not suffering from too great exposure of either sort. Special precautions should be observed by workers with larger amounts of radium, as in preparation of the luminous compound. 03118585 HWBB-0011565 Industrial Hygiene Digest - 7 December, 1945 1726 A Simple ?nd Accurate Method for thn .Determination .of Mercury in Biologic Material. T.H. Maren. J* Lao. Clin. Med., 28, 1511-1514 (1345) A colorimetric method is described for the analysis of mercury in biologic ma terials. It is simple, -*nd *in analysis can be completed in five minutes once the organic material has been digested. Dithizone in chloroform reacts with mercury at pH 1 to give a yellow color which is analyzed by the "mixed color method" in a spectrophotometer. Direct titrations can be made in the absence of a spectrophotometer.

Adequate exhaust ventilation system end proper personal protective equipment are required for workers exposed to s*nd blasting, welding *nd acetylene cutting, buffing and grinding of metals, and to toxic and dermatitis-producing chemicals. For workers in lead, zinc and various gases there should be frequent physical examinations, and for those exposed to metallic dust, frequent chest X-rays. The noise hazard is often neglected and should be reduced wherever possible by damping vibrations, insu lating enclosures end by the use of individual ear-plugs. Many operations with mewns of protection are listed, with illustrations. 1229 Evaluation of Methods to Control Air-Borne Infections. J.E. Perkins. Am. J. Pub. Health, 55, 891-897, 951-952 (Sept., 1945) This paper reviews briefly the development of modern conceptions of the role of ir in transmitting communicable diseases, and outlines the problems ahead. Possible methods of control of air-borne infections in enclosed spaces are clas sified by (A) point of application, *nd (B) method of control. (A) separates procedures directed at: (1) reservoir of infection: droplets end droplet nuclei from husrns -nd dust *nd lint from bedding, clothes, bandages, etc.; (2) sus ceptibility of individual; and (5) mode of transit8sion from reservoir to sus ceptible individual. (B) includes: (1) isolation and quarantine; (2) chemo therapy; -nd (5) other methods of rendering non-infectious, covering a wide variety of agents, ns: oiling; vaccines end sera; chemoprophylaxis; mechanical barriers of masks, partitions, controlled air currents, ^nd filters; dilution of air; reduction in crowding; disinfectant radiation bv daylight or artificial illumination; and disinfectant vapors. An editorial reviewing the pr-per (ibid. 951) adds that to arrive at sound engineering conclusions, three steps seem essential: (1) standard laboratory methods for quantitative estimation of microbe pollution in Idle atmosphere must be agreed upon; (2) extensive quanti tative studios must bo made in various occupied places using identical and 03118586 C=fl Industrial Hygiene Digest - S December, 1945 comparable methods, so as to provide a reasonably accurate standard to distin guish .*. safe atmosphere from a dangerous one; 2nd (3) such a standard must be applied under practical conditions to the testing of various procedures for the purification of the atmosphere so as to establish the efficiency and economy of each. 1250 Solvent Hazards in "Safen Plants. Mable Foy. Safety Eng., 90, 107-112 (Oct., 1945) In supposedly "safe" plants several instances are given of the use of substituted unknown solvents, of inadequate ventilation, of insufficient protective clothing and of careless .supervision of preventive measures, which have resulted in ill ness to workers and property damage. In order to help diminish the accident rate, the following should be observed: (1) know the nature and hazards of sol vents in use ?nd possible substitutions; (2) check the ventilating system with special attention to the possibility of corrosion, air currents, and interrup tions in operation; (3) examine carefully each special emergency, repair or cleanup operation before it is begun; (4) help the worker protect himself by giving him adequate information about the dangers of his job and how to use the protection with which he is furnished; and (5) be sure that there is constant cooperation with the employment and medical departments 1251 Chemical-Resistant Gloves.

A. Nutting. Southern Power and Ind., 63, 115-113 (1945) For successful operation, the air velocity must be maintained within limits if the usual design efficiency of 85% is to be attained; 90% efficiency requires a reduction in air velocity of 20%. Air distribution must be constantly uni form ovc-r the entire face area of the filter. Access of rain must be prevented by louvers, and preheating coils provided if snow or fog is encountered. Screens are desirable to keep out foreign materials, and filters to remove lint, if this is present. For excessive dust loads, precleaners are desirable. The alterna ting-current supply to the power pack should not have voltage variations greater than + 10% of the nominal value. Adequate space for maintenance and easy access is required. -- C.A. * 1255 Experiences with the Use of Propylene Glvcol as a Bactericidal Aerosol in an R.C.A.F. Barracks. J.M. Mather and A.D. McClure* Can. J. Pub. Health, 36, 181-187 (May, 1945) Propylene-glycol vapor in a concentration of less than 0.1 mg. per liter of air did not lower the incidence rate of respiratory illness nor the streptococcus hemolyticus carrier rate during a season when these rates were already abnor mally low. At this concentration it showed little germicidal activity. When present in a concentration greater than 0.1 mg. it is definitely bactericidal, but it is not practicable to maintain this concentration in the present type of barrack block. -- Authors' conclusions 1234 Study and Control of Industrial Atmospheric Pollution Nuisances. F. M. Stead. Am. J. Pub. Health, 35, 491-498 (May, 1945) Industrial atmospheric pollution nuisances include inert smokes and dusts, mucous membrane irritants and malodorous substances. The minute smoke particles are rarely a cause of complaint by urban populations. Odors are very difficult 03118587 HWBB-0011566 HWBB-0011567 Industrial Hygiene digest - 3 December, 1945 to evaluate and localize. After the source of the nuisance is determined, the investigator must find what changes in plant processes will alleviate the situ ation. Rather than repeatedly persuade or force management to control the re curring nuisances, the author v:ould depend on long-time planning, such as care ful industrial zoning and enlightened legislation. -- J.I.H.&T.

Acta radiol., 24, 206-216 (1945) Bronchography allows an intra vitam study of the changes of the topography of the bronchial tree which occur when the contraction sets in in third stage sili cosis. When the center of contraction is situated characteristically, above, lateral to and behind the hilus, it exerts its greatest pulling effect on the ventrally situated bronchi, of which the proximal is dislocated upwards, so much so that in severe cases right angles occur. The position of the dorsal bronchi is affected to a minor extent. The massive lesions are mainly situated in the epartericl bronchus' region of distribution on the right side and that of the first hyparterial bronchus on the left side. When the center of con traction is not situated typically, the changes in the topography of the bronchi are subject to variations, depending upon the position of the massive lesions. -- Authors' summary 1236 Egg-Shell Calcifications in Silicosis.

(2) The few authors who have hitherto reported on such shadows have differed in their statements regarding the distribution of them in the pulmonary roentgenogram. Some have stated that they exist only in the hilar areas; others have described their presence in the lung parenchyma as well. The cases in this report appear to confirm the latter view. (3) The previous authors have also differed in their interpretations of the cause of these shadows. They have variously labeled them as being (a) cal cified tuberculous lesions, (b) uncalcified silicotic densities, and (c) calcium degenerations in or around silicotic nodules. (4) To these a fourth viewpoint is now added; that the densities under discussion may represent the results of inhalation of calcium along with the silica particles. (5) In the absence of definite knowledge of the cause of egg-shell calcifications, the clinician and roentgenologist rho encounter them are placed in toe difficult position of de ciding whether they represent a complicating, tuberculosis infection or a less serious condition. -- Author's summary 1237 Silicosis of the Peric;jrdium --2 ase Report. Marguerite G. Stemmerman. Am. Heart J., 2S, 642-647 (May, 1945) A case report of a person with extensive adhesive pericarditis due to spread of pulmonary silicosis is given. The patient, a 51-year old white male, had symptoms from his lung condition for seven years prior to his death from silico- tuberculosis and progressive pulmonary failure. The only subjective or objec tive clinical evidence of cardiac disease in this case was an abnormality of the electrocardiogram, but toe author is of the opinion that had the patient lived sufficiently long, signs of cardiac embarrassment might have developed. At autopsy extensive pulmonary and pleural silico-tuberculosis and adhesive 03118588 oo t=a In"ustri-1 Hygiene Digest - 10 December, 1945 pericarditis was found. It is believed the silica particles found their way into the pericardial cavity through the small superficial lymphatic channels of communication between the pericardial and pleural cavities. The fact that the firmest attachments were .*t the site of the densest pleuro-pericardial ad hesions, at which point the pleura and both visceral ~nd parietal pericardium were cs one, w*.s the major evidence in favor of this view. -- J.I.H.&T. 1238 Silicosis - Its Prevention and Treatment.

C.U. Demehl and C.A. Nau. Tex'S F.epts. on Biology rnd Med., 3, 227-237 (Summer, 1945); Ind. Med., 14, 744-754 (Sept., 1945) ~ The authors review progress on dust disease during the past few years, includ ing (1) evidence from several sources refuting the silica solubility theory of silicosis; (2) aluminum therapy; (3) pulmonary lesions produced by cotton dust; (4) welders' sidorosis. A dust exposure apparatus is described by means of which it has been shown that antimony trioxide is many times more toxic when inhcled as when administered intraperitoneally. Their experiments will be re ported later in gre ter detail. 1241 Health nd Environmental Conditions in the Iron Industry. G.F. Keatinge and K.M. Potter. Brit. J. Ind. Med., 2, 125-141 (July, 1945) A brief description is given of modern iron-founding methods. Environmental studies were carried out in two foundries employing over 200 workers. These studies included a survey of ventilation and heating, and the dust hazard. To assess the dust hazard in a foundry knowledge is required of (a) the dust con centration in the work atmosphere, (b) the duration of work spells, (c) the cheraic?! composition of inhaled dust, and (d) its pnrticle-size frequency. It is shown that fettlers of medium end large castings have the dustiest occupa tion in the foundry, and the dust here consists largely of silica particles* It is estimated that the silica hazard of the fettler of large castings is fifty times that of a worker in the general body of the foundry; medium fettling hr.s a nine times greater hazard; end pneumatic mould-filling five times greater; workers in the core shop have toe least exposure. The simplest way to maintain routine control of atmospheric pollution in a foundry is by mass concentration estimation of 'ir-bome dust at breathing height. Sickness and accident rates among foundry-workers as compared with those in the constructional department showed tort: (1) toe number of cases of respiratory disease was less although toe average number of days lost per case rrs higher, and while some lungs showed evidence of "dust change" there wes no case of silicosis; (2) skin af fections were grer.ter, *'*ith the most dermatitis among the core workers; (3) the incidence of rheumatic disease -was greater; (4) accidents causing injury were fewer and caused less lost tiiae; end (5) among foundrynen heat cramps are un common but not unknown. Preventive measures against accident rnd ill-health are (*) pre-employment medical examination, including chest X-ray; (b) improve ment of ventilation by modern construction methods; (c) proper cloak-room, washing rnd bathing freilities; (d) attention to floors; (e) by adequate pro tective equipment for the individual worker; rnd (f) prevention of fumes and 031185S9 HHBB-0011568 oo C=fl Industrial Hygiene Digest - 11 December, 1345 dust by alteration in materials where possible, by increasing mechanized method of production, and bv good general house-keeping. -- From authors' summary 1242 Chronic Exudative and Indurative Pneumonia Due, .to Inhalation of Shellac. E.r. Hirsch end H.B. Russell. Arch. Path., .39, 281-28C (May, 1345) Chronic progressive induration developed in the lungs of a man engaged in manu facturing furniture. The postmortem examination demonstrated chronic diffuse exudative :ind indurative pneumonia in both lungs. The character of the consoli dated tissues in the lungs and the small deposits of fibrin on the visceral pleura suggested grossly the possibility of some form of lipoid pneumonia. Ethyl alcohol and ether extraction of the lungs yielded large amounts of a viscid ma terial like shellac dissolved in an oil medium. This material injected into the trochees of rabbits caused necrosis and marked exudative and fibroplastic inflam mation of the lungs. The exudative end fibroplastic tissue response approximates the changes reported in tissues with oils like cheulmoogra. Lac substances have a high content of certain fatty acids. Fatty acids of this character are known to cruse necrosis and marked exudative and proliferative tissue reactions. -- Authors* summary 1243 Case of DDT Poisoning in Man. V.B. Wigglesworth. Brit. Med. J.,,1, 517 (Apr., 14, 1345) ' The case is reported of a man who underwent exposure on three times to large amounts of DDT in acetone solution while conducting experimental studies on its loc-'l irritant action on the skin. He developed general intoxication and on three occasions he experienced involuntary muscular tremors over the entire body. After two weeks of bed care he began to make a slow recovery. He was away from work for 10 weeks and had not recovered completely at the end of a year. His condition improved rapidly when the true nature of the affection was known, which suggests that his symptomatology was influenced by anxiety. 1244 The Toxicity of DDT. G.R. Cameron and F. Burgess. Brit. Med. J., 1, 865-871 (1945) The toxicity of DDT was investigated on a variety of animals and on human sub jects. It is tolerated in large amounts when administered in single or repeated doses. Danger to health is likely to arise only in the careless use of concen trates. Prolonged contact with undergirments impregnated with the insecticide did not produce r. toxic effect. -- C.A, 1245 Th_e_Medi crj nd_ Public Health Import-nee of the Insecticide DDT. F.C. Bishopp. Bull. N.T. Acad. Med., 21, 561-580 (Nov., 1945) The value of DDT `S hi insecticide md the forms in which it is used are dis cussed. No toxicity or irritation results from 10% DDT in pyrophyllite applied s a dust to the skin, but in oil solutions it can be absorbed through the skin. T^e chronic toxicity of DDT in various forms has not been fully evaluated, but from available facts it may be concluded that DDT is much less dangerous to man from direct toxic action than most other insecticides. However, it should be handled with crc to avoid ingestion and prolonged contact of oil solutions with the skin. It is important that it be applied by the right method in the right IOITC. 1246 ' Determination of 2.2-Bis (p-Cliloroohenvl)-1.1 .l-Trlchloroethene (DDT) in Organs arid _3odv Fluids After Oral Administration. H.A. Stiff, Jr. and J.C. Castillo. J. Biol. Chem., 15S, 545-548 (1945) DDT was not found in the organs or body fluids of rabbits after oral administration of toxic doses. Determinations were made by the xnthydrol-potassium-hyaroxide-pyridine method. It appears that when administered orally, DDT is not 03118530 HHBB-0011569  CLi--oi C=fl Industrial Hygiene Digest - 12 Q December, 1945 un absorbed in its unchanged state, but that other organic compounds of chlorine ere formed which are assimilated and can be detected in the organs and body i fluids. These organic chlorides do not normally appear in the body fluids ?n tissues of animals. It is suggested that DDT is transformed to other organic* chlorides in the alimentary system rnd that only these organic chlorides 're absorbed. -- C.A. 1247 Ethvlene Dichlorids as Degreaser., and Paint Remover. T.J. Carter. Safety Rev., 2, 10 (Nov., 1945) Industrial health reports indicate that ethylene dichloride (1,2-dichloroethnne) is being used for removing preservatives from new equipment and that it is a major constituent of a point and varnish remover. It should be pointed out that ethylene dichloride is both flammable rnd explosive, and that its flash point is 65 F (open cup) rnd its vapor will explode when mixed with air in concentra tions ranging from 6.2 to 15.9 percent. Also, it is a powerful narcotic, is rn irritant, and hes a toxic action upon the heart. It should never be used with out adequate ventilation and proper respiratory protection to prevent inhalation of vapor. The accepted maximum permissible limit for an eight-hour exposure is 100 P.P.M. 1248 Methvl Chloride Intoxication. H.G.S. van Raalte and H.G.E.C.T. van Velzen. Ind. Med., 14, 707-709 (Sept., 1945) . Symptoms of acute methyl chloride intoxication are mainly those of asphyxiation and shock, -"ith irritation and later depression of the central nervous system, accompanied by acidosis and disturbance of the functions of the liver and kid neys. Oxygen therapy immediately is advised, and the administration of dextrose, sodium lactate and blood plasma by intravenous drip} if necessary to stimulate 'a depressed central nervous system, coranin and lobelin should be chosen. In cases of chronic intoxication with methyl chloride the symptoms are mainly those of degeneration of parts of the nervous system, hence care should be directed toward rest, physical therapy and a diet rich in proteins, vitamins and minerals, plus huge doses of thiamin given perenterally. The details of the case which lead to the publication of the article are given. ' 1249 Storing and Handling Chloroform. R.N. Anderson. Safety Rev., Zf 9-10 (Nov., 1945) Chloroform is not easily ignited but at high temperatures it breaks down readily into hydrochloric acid and phosgene. Chloroform not only can cause direct bums but can ''Iso be absorbed through the skin, therefore when 3pilled on the skin, it should be immediately removed by washing with a large quantity of water. Skin contact should be avoided. From 0.02 to 0.055 is the lowest amount that S can be detected by smell and as the concentration increases, symptoms of dizzi--,, nes% nausea and faintness become increasingly severe above 0.10%, there are i definite after-effects of fatigue and headache lasting for many hours. In the event of leakage or breakage of containers in the storage place, no one should be allowed to enter unless adequately protected by an air-line respirator- or . self-contained oxygen-mask. 1250 Carbon Tetrachloride Poisoning. S.M. Dillenberg end C.M. Thompson. Military Surgeon, 97, 39-44 (1945) Twenty cases of carbon tetrachloride poisoning occurred from its use as a cleaning solvent in a confined compartment of a submarine. One was e fetal case terminally presenting pulmonary edema. Only two patients worked with the sol vent, the ethers inhaled the fumes by being in or near the compartment over a period of two days. In addition to the one death, four were made critically ill. The predominating symptoms were gastrointestinal followed by renal shut down. Clinic studies revealed no evidence of liver damage, which is in contrast 03118591 u--d c=a Industrial Hygiene Digest - 13 December, 1245 [J^ --i to ether cases reported in the literature. The organ primarily involved was o the kidney. Microscopic studies revealed marked liver, kidney, and adrenal damage. Respiratory complications occurred late in the symptom complex, and cd there were radiograohic changes in the lung field of the four seriously ill. a The authors conclude that carbon tetrachloride must be considered a potent * poison for it c?n be absorbed through the skin, inhaled, and ingested, and that careful instructions as to its proper use should be given. -- C.A. 1251 Acute but Moderate Carbon Monoxide Poisoning. 2.

Scand., Q, 67-78 (1943) (Scandinavian) The inhrlation of carbon monoxide to the point of formation of ?5-32 carbon monoxide-hemoglobin Cr?.uses sn increase in relative cell volume and plasma- protein concentration. Neither the glucose nor lactic acid concentration in the blood were affected as long as the subjects remained quiet. Sugar tolerance ras not altered at all by the carbon monoxide intoxication. -- C.A. 1252 Effects of Oxygen at Increased Pressure. J.W. Bean. Physiol. Rev., Z5, 1-147 (1945) Pulmonary pathology caused by OHP (high oxygen pressure) contricutes to the reactions of poisoning by interfering with normal carbon dioxide removal, but such pathology is often absent and cannot, therefore, be regarded as essential in the poisoning by OHP. Repeated exposure to OHP induces permanently crip pling motor dysfunction, Kich indicates permanent damage to the central ner vous system, and this is further substantiated by recent discovery of degenera tive changes. Under OHP there is increased carbon dioxide tension of the tis sues associated -1th a failure of oxyhemoglobin to become reduced. It seems that even a slight rise in carbon dioxide tension under conditions of OHP is greatly potentiated, throwing an additional load on an already disrupted carbon dioxide transport system, and this constitutes an important etiological factor in OHP poisoning. The cellular metabolism is decreased through the direct in hibition of tissue oxidations by OHP, as well as by the increased tissue carbon dioxide tension and acidity. The direct effect of OHP is exe2'ted through action on the enzymic processes. The evidence presented indicates that the disruption of enzyme activity leading to hyperoxic anoxia and tissue acidity may be the ultimate cause of the OHP poisoning.

Science, 21, 506-536 (Oct., 1945) The three common 'md obvious difficulties experienced by aviators at great height are: (1) 1-ck' of oxygen; (2) ear and sinus trouble due to non-equaliza tion of pressure between the middle ear end the external atmosphere; *nd (3) intestinal pains due to expansion of gas in the intestinal tract. But at altitudes of 25,000 to 35,000 feet a fourth group of additional symptoms may appear which affect various parts of the body. These range from a mild rash or ache to unbearable pain near the joints, from tightness in the chest to serious coughing spells and from hyperesthesias or mesthesias to convulsions* paralysis ~nd syncope. The individual is definitely incapacitated, sometimes seriously. It has long been recognized that compressed air illness is due to bubble fermrtion in blood and tissues, and this discussion covers experiments of various types on animr Is end men as to the causes and prevention of the babbles. Analysis of gas bubbles in the blood indicato a very high percentage of nitrogen end the breathing of oxygen for a sufficient time before ascent will flush out tile nitrogen, md completely prevent the appearance of all symp toms of decompression sickness, thus offering the most effective prophylactic treatment. Tho amount of oxygen breathing necessary depends on the extent of exercise at altitude. The use of drugs in reducing the incidence of decompres sion sickness has not yet been thoroughly tested. The bubbles may form in 03118592 c=o Industrial Hygiene Digest - 14 rsi December, 1945 [J^ almost any part of the body, but air masses have been found by X-ray to be s present in joint cavities end in fascia between muscles and these caused no pain. Nervous symptoms and skin rash have not been fully explained. In cong elusion, the article states, "Some details remain to be filled in but on thesx whole the etiology of decompression sickness can be expressed by the one worlF -- bubbles." 1254 Adrenal Cortex snd Work in the Heat. M. Moreira, R.E. Johnson, A.P. Forbes, and F. Consolazio. Am. J. Physiol., 145. 169-176 (1945) The effects of large doses of extract of adrenal cortex were studied in healthy young men living on a constant adequate diet and marching 3.5 hours daily in moist heat. The extract had no effect on their performance or feelings. It has no effect on physiological or chemical functions such as heat balance, res piratory exchange, rectal temperature, rate of sweating, skin temperature, res piratory oxygen consumption and carbon dioxide excretion, blood pressure, serum chloride, sodium, potassium, non-protein nitrogen, or daily urinary ex cretion of sodium rnd of chlorine. On drys when extract was injected, the urinary excretion of potassium was increased. There was slight evidence that the extract lowered the concentration of chlorine and. sodium in the sweat and raised the concentration of potassium. -- C.A. 1255 Consideration of Iniurv as the Cause of Cancer. F.E. Adair. Compensation Med., 1, 5-6 (Dec., 1945) "A follow-up of severe human injuries such as civil and military injuries has failed to convince scientists that injury plays any role in the production of human c.-ncer." The author's own medical and court experience has confirmed this statement. He suggests that the entire problem of injury as the cause of cancer be taken out of the hands of the courts, and placed under the juris diction of a commission of eminent physicians and judges. 1256 Penicillin in the Treatment of Experimental Infection with Bacillus Anthracis. F.R. Heilman and W.E. Herrell. Proc. Staff Meet., Mayo Clin., 19, 492 (Oct. 4, 1944) Fifty-five percent of mice treated with penicillin were protected against 10,000 times the lethal dose of Bacillus anthracis, even when 16 hours had elapsed between the inoculation and the beginning of treatment. It is evident that infections with B. anthracis are susceptible to treatment with penicillin. -- Arch.

Med., 14. 639-646 (Aug., 1945) The chemical manufacture end packaging of nrsphencmine and related compounds are attended by the escape of dust in many different stages. The amount of arsenic in this dust in one pharmaceutical plant was .found to vary from 0.0002 to 0.017 milligrams per cubic foot. Urinary excretion did not reflect any absorption of organic arsenical dust at the low level of exposure encountered in the packaging department; at higher levels of exposure in the manufacturing department, increased urinary excretion was present, roughly in proportion to the magnitude of the exposure, the mean for the former .group was 0.014 mil ligrams per cubic foot, for the latter 0.059, and for normal controls 0.017, Clinical judgment did not give the impression that ~ny symptoms of arsenic poisoning existed except in a few isolated vrorkers in the manufacturing depart ment during s short period of unusually heavy exposure. Case reports of three workers showing transitory symptoms of borderline arsenic poisoning are pre sented. An analysis of 323 periodic complete blood counts in workers exposed to arsenical compounds and 221 counts in unexpo3ed workers doing otherwise similar work revealed no evidence of myelotoxic effect due to arsenicals. -- From authors' summary 03118593 5=3 t=fl Industrial Hygiene Digest - 1 m December, 194^ 1258 A Program of Industrial Vision. L.H. Whitney, (Reprinted from Executives Service Bulletin, Metropolitan life Insurance Co., June, 1945.) Ind. Med., 1, 320-323 (Oct.,1945) g Visual performance is one of several important br.sic skills which influence ** employee efficiency. A practical safetv program for eye protection is describ ed which has two main objectives: (1) the placement of applicants into posi tions for which they are qualified visually rs well as physically; rnd (2) the provision of safety glasses free of charge to ell employees assigned to hazar dous areas. It has demonstrated that teamwork can exist among the safety en gineer, psychologist, optometrist, ophthalmologist and general industrial phy sician when there is a definite goal. Further research is being encouraged in vision problems, including illumination, special color and contrast painting of factory equipment, vision training .and vision problems affecting safety measures. 1259 Qphthamologv in the Factory. I. Mann. Brit. J. Ind. Med. 2, 169-170 (July,1945) The eye can be regarded from two aspects, either as an optical instrument, the imperfections of which can be remedied by mechanical means, or as a living or gan which may become diseased or can participate in general diseases of the body. Upon entrance the eyes of ell factory workers should be examined from both aspects, and the tests should include visual acuity at the distance of the proposed job. Thus suitable optical instruments mc.y be fitted so that each employee may work in comfort. The ophthamologist should see that conditions of illumination ^re satisfactory. It is recommended that each worker should have a periodic eye examination every three to five years. Industrial eye diseases peculiar to each factory involved should be studied and understood by tiie factory doctor, *nd any red or painful eyes should be reported and investi gated at once; if a condition or injury is serious it should be sent to the hospital. Possibly the greatest need today is for the production and populari zation of a comfortable and efficient protective goggle. 1260 Effects of Exposure to Ultra-Violet Light on Visual Thresholds. E. Wolf. Proc. Nat. A. can. Sci. 51, 23S--241 (Aug., 1945) Experiments with baby chicks reveal thet exposure of eyes to ultra-violet light ranging from 300 to 365 millimicrons in wave length, a range previously considered harmless by some authorities, delays dark adaptation and impairs visual functions even when the eyes themselves show no obvious injury. Since the visucl characteristics of chicks' eyes approximate closely those of a human, the author concludes that protective lenses excluding the- dangerous rays should be worn by welders and their helpers, skiers, fliers, sun bathers and others oxnosed to the radiation. 1261 Unusual Forme of Nystagmus.

Several clinical syndromes have been reported: white fingers, arthritis of the wrist, elbows ar.d shoulders; the formation of areas of decslcification in the bones of the carpus; and injuries of the palmar aponeurosis and the ulnar nerve. The authority for each of these conditions is given. The most important of these syndromes is the vascular disturbsnce which produces anemia of the fing ers of the band holding the tool; cold is a precipitating factor. When once "white fingers" have been established they tend to recur even though use of vibrating tools has been given up.

The author has found that the non-soluble oils which S hove been thinned with paraffin tend to produce severe acne and severe eczema* toid rashes, whereas the soluble oils have the opposite effect. The thick, heavy oils rre not necessarily the most toxic. Discussion is given to show thrt the more refined lubricating oils usually cause less trouble then the cruder forms. Investigation by industrial chemists would do much to end the uncertainty of this problem.

Industrial Health Officer, Philadelphia Rsvy Yard. Safety Rev. 5, 12-13 (Oct., 1945) An outbreak of dermatitis occurred among 150 workers employed in processing khaki cloth that had been treated with an antimildew agent. The eruptions were essentially erythematous, papule pruritic, and eczematous, not vesicular or suppurative. The antimildew agents are a group of chemicals with known skin sensitizing properties. Sensitive persons either become hardened or develop an eruption. It is advisable to permit persons with light eruptions to continue at the operation for two weeks, using skin protective creams and bland washing agents, or if the protection is inadequate, leather, synthetic rubber or vinylite gloves. If the eruption does not subside the worker should no longer handle the treated cloth. Directions for patch tests are given. 1271 A New Dressing for Bum.s_._aad Extensive Abrasions. G.S. King. Ind. Med. 14. 796-797 (Oct., 1945) The author describes his own method of applying dressings to bums. An envel ope of verv thin, pliable cellophane is used. The lower surface of the en velope is perforated with many very Small holes, while the upper surface is left intret. The envelope is filled with the desired medication and applied with the perforated side directly upon the burned surface. As the ointment gradually melts it seeps through the openings to come in contact with the . wound. The dressing may be left in situ without change at least twice as long as a gauze dressing, and it is easily removed without pain or adhesiveness to the wound surface. The envelopes of medicated ointment may be prepared in advance and kept in jars in layers to be removed one at a time.

I.H. Tebershaw and B.D. Tebbens. Ind. lied. 14, 709-711 (Sept. 1945); J. Med. Assoc., Alabama (Sept. 1945) This paper constitutes a review and analysis of the use of aluminum in the control of silicosis, by means of data gathered by personal interview and ob servations at various centers in the United States where aluminum is used either sc a prophylactic or therapeutic agent. The following points have been established by animal experimentation: (l) if alumina and quartz lodge in the same cell the effect of the quartz is neutralized; (2) further progression of tissue reaction is arrested by this phenomenon; (3) mature silicotic lesions become static and immature lesions are resolved; (4) the presence of aluminum does not lter the distribution of quartz in the tissues; (5) the effect of aluminum after inhalation is prolonged (a single large dose may remain in the tissues for over a year); and (6) the presence of aluminum in the tissues pro duces no toxic effect in healthy animals with one possible exception, that hydrated alumina in large doses may alter the body defenses against tubercu losis. The authors discuss the merits of a particular type of hydrated alumina, as used by Gardner, and aluminum used throughout in the Canadian investigations, and concludes that the choice is a matter of personal preference. After re viewing the work of Hr;nr.on on therapy and discussion of the place of aluminum in prophylaxis, the authors conclude: (1) the widespread use of aluminum as a therapeutic agent should be encouraged if strictly controlled by means of medical observations; (2) aluminum therapy should also be used in limited number of silicotics without disability such as those still, or recently ex posed to silica dust and individuals with a precocious susceptibility to the disease; (3) os a. prophylactic agent aluminum should be considered only an f.djuvant tc engineering control. 1274 Aluminum Therapy for Silicosis. D.R. Johns and S.J. Petronella. Monthly Bull. Indiana Strte Ed. Health, 48, 203, 216-217 (Sept. 1945) ' A report on aluminum therapy and prophylaxis, using 276 employees of a foundry, 75 of which completed treatment. Each man was given a thorough examination, including chest X-ray, before and after the 30-40 treatments, which completed the course. The methods of preparing the aluminum and of administration, are ` fully described. The subjects were classified into eigit groups before and sfter treatment, depending on the presence and state of.silicosis, and then . into four groups indicating the degree of improvement. None of the subjects treated became worse. The authors conclude: (1)"Inhalation of aluminum powder, while not a cure for silicosis, results in the amelioration of symptoms of silicosis snd an increased capacity for work in a significant high percentage of cases. (2) Inhalation of aluminum powder gives no evidence of toxicity. (?) There is early evidence that aluminum therapy will be of value as a pro phylactic measure." The experiments are still in progress at the plant men tioned shd at one other, ana fuller results may he expected in the future. (Ed. Note: The data indicate that while 52% of the test subjects "1th defi nite evidence of silicosis experienced "definite improvement", 62% of those without evidence of silicosis also experienced "moderate improvement".) 03118597 2 (01 M 0 Co C=3 Industrial Hygiene digest - 19 December, 19 =5 ^ rtA** 1275 Tr.f.'istrial Zenith Examinations .in tile Iron and Steel, industry.

Four principal types of examinations are considered: (1) Primary exrmination, given to an applicant, is a complete examination for* general fitness, discovery of minor disabilities, for -vn initial industrial health record. (2) Special examination, after illness, injury or transfer, and limited largely to the needs of the occasion, or to special requirements of the job. (3) Secondary examination, given periodically to employees in occupations which involve known health hazards, with a view to protecting the employees. (4) Termination examination, given on termination of employment after illness, injury or for other causes, in order to determine any ill effects from his employment. The scope of any industrial health examination should be suffi cient to provide a reasonable appraisal of the applicant1 s physical and mental fitness for employment* The examining physician should be familiar ^ith em ployment requirements in the iron and steol industry, end a female attendant should be present during the examination of women. All findings of a question able nature* should be discussed with the examinee and with his family physician. It is suggested that each applicant be requested to sign a form stating that the medical examiner has informed him of any ailments, defects, or physical or mental disabilities, which h*ve been revealed. Simple forms or re-commended methods are presented as general suggestions but many of them may vary with the size of the plant, the executives of which 3hould study, select and adapt the suggestions to their respective requirements. 1276 The Personal Side of the Amp' Industrial Medical Program at the San Francisco Port of Embarkation.

Program for Federal Employees. J.**\ Cronin, B. Solby and tt'.S. Tilder. Pub. Health Kept. 60, 1525-1536 (Nov. 9, 1945) The introduction of mental hygiene programs into industry results from the conviction that thev will benefit both production and performance. This exten sion of mental hygiene measures beyond the traditional limits of the medical field into the realm of personnel administration, points to completely new vistas of mentrl health for our adult productive population. In addition to the preventive aspects of such a program an unexplored field of psychotherapy is opened, in which the psychiatrist becomes an educator as well as a physician. Psychiatry in industry will not take the place of efficient personnel management and supervision, but it offers a new orientation as basis for methods which personnel management will develop. -- From authors* conclusions. 1281 The Future of Medicine in Industry. H. Bartle. Ind. Med. 14. 794-796 (Oct., 1945) The author sees the future of industrial medical service as the unlimited appli cation of the achievements of medicine and surgery to the welfare of all workers and he believes that "industry and labor, in splendid team work, will support and promote medic',1 research, fellowship and other features to promote and ad vance industrial health". 1282 Simple Guides for History Taking. C. Leggo. Ind. Med. 14, 697-698 (Sept.,1945) A guide to sound practices in co.se history recording in the industrial dispen sary is offered, with comments which apply regardless of the form in which the record is kept. The principles laid down attempt only to describe the essen tials of c^se recoiling end the special points stressed are: the date should include the year; the nistory should describe when, where, how, what, and the treatment and disposition of each claimed injury; any unusual incident should bo mentioned; each entry made bv cither o nurse or a doctor must be signed. 1283 Added Infection in Industrial Founds. B. Clayton-Cooper and F.E.O. Williams. Brit. J. Ind. Med. 2, 146-153 (July, 1945) . Of 531 small wounds and septic lesions examined in the surgeries of 19 different factories, 483 were infected with pyogenic cocci. In general, the older the wounds the higher was the infection rate. A detailed comparison of 472 wounds treated in two factories engaged in similar work, tut where different dressing routines ^ere followed, shored that the incidence of infection was less in the surgery ^hure the wounds ^-ere treated with a relatively rigorous no-touch dress ing technique. In the surgery with the higher infection rate, where the wounds vere handled more freely, the obvious deficiencies in Idle dressing routine were of the kind that would facilitate the spread of pyogenic microbes from one pa tient to another and it is highly probable that cross-infection of this kind was responsible for a substantial part of the difference in infection rates. The extra berden of infection associated with the less rigorous technique is not primarily an indication for the adoption of a full aseptic routine since, in the small wounds studied, infection did not notably increase the average 03118599 Li--J C=3 On Industrial Hygiene Digest - 21 December, 1945 ri disability to the patient. Nevertheless the hish incidence of infection in- dicatos the existence of a risk which, in tne long run, -'dll manifest itself i in occasional severe infection, particularly of large rounds; e risk which, [g in our opinion, can be substantial!'/ minimised cr the ^dootion of a simple bi|g rigorous routine of dressing. -- Authors' summary*. 1284 Education in Industrial H-or 1th. Report of the Education Committee of the Association of Industrial Medical Officers. Brit. J. Ind. Med. Z, 158-165 (July, 1945) Great Britain has the same general problems in industrial health as the United States. Their present facilities for education in industrial health are quite inadequate but toere is prospect of early improvement. Undergraduate training in industrial health should be carried out in every medical school end medical post-graduate training should be available at universities in industrial areas. There is need for the training of nurses for industry and for the education of laymen in industrial health, especially social workers and hospital personnel. After a term of post-graduate study a Diploma of Industrial Health should be instituted solely by the Royal Colleges. -- From authors' summary. 1285 Industrial Health. A Tale of Three Cities. Health Advisory Committee, Chamber of Commerce of the United States. Washington D.C. 24 pp. (1945) Recent advances in industrial health plans in three typical American cities are described. I. TTillismsoort. Pa. Industrial health service in 1945 was inadequate rs in most cities. The first step was a campaign of publicity and education of the public end of individual companies conducted by several in terested societies. Then the main program began with X-ray chest surveys, blood tests for venereal diseases, follow-up supervision of those diseases and pdvising employers on veteran rehabilitation. As results of the campaign to date: (1) 11 of the larger companies have integrated medical service or health units} (2) 61 industries have some degree of medical service; (5) at least five out of seven plant employees have group health insurance; (4) at least four out of five employees have had chest X-rays and all school children will be X-rayed in 1945} (5) employees and homemakers have been impressed with the importance of proper nutrition; and (6) absenteeism has been decreased in plants having health units. Many letters testify to the success of the pro gram. The general plan adopted by the Lycoming County Medical Sooiety for small plants involves the presence of a physician for a stipulated time at each plant, with a minimum of an hour a week per 100 workers, and the same physician may be retained permanently or a plan of rotation used. II. Phila delphia. Trade and medical organizations cooperated in developing a general industrial medical service program. Five alternate methods for small plants are proposed, two of which are variations of the Lycoming County plan, and the others involve dispensaries established and supported by a group of small industries in the same building or adjacent. Publicity, contact with a number of industrial groups, and full discussion of possibilities are still a part of the growing program. Out of 623 industries contacted, 98 have.instituted or added some form of medical service plan. III. Los Angelas. The program of publicity education, X-ray examinations and blood tests were much the same as in the other cities, especially as given for Williamsport, md the extent of the tests is rapidly expanding. Other problems attacked include hospital facilities, cross connections in the water system, mosquito and rat abatement, smoke and fume control, dental hygiene, veteran relationships, interruptions in garbage collections, end health legislation. Here also industrial health service in small plants is receiving a large share of the attention. The con clusion states that the accomplishments of these three cities may be duplicated in *tny other city through initiative and cooperation of the chamber of commerce or similar trrouo with the medic*! society. _ ^ _____ 0.3118600 M L--u c=a Industrial Hygiene Digest - 22 December, 1345 1286 Dental Programs for Indiana Industries. L.D, Heaccck. Monthly Bull. Indiana State Bd. Health (Oct., 1945) Dentistry is receiving recognition as part of industrial hygiene. The indus trial dental program should be staffed and equipped to render dental services, including: (1) preplacement and periodic oral examination and diagnosis for ell employees; (5) emergency service, including the treatment of occupational injuries and disease; (3) treatment and eradication of oral sepsis; (4) ade quate recording of findings and recommendations; and (5) education in dental health and follow-up of individuals to encourage complete and regular dental service. The dental program should be an integral and well coordinated part of the industrial health service and in large plants may require the full time services of one or even more dentists. 1267 Standing Orders for Nurses in Industry. American Mutual Liability Insurance Co., Boston. Ind. Nursing, ^4, 15-22 (Sept., 1945) This pamphlet for industrial nurses presents a uniform set of orders which should serve as a guide for treatment and advice to the workers who come to the plant dispensary. These orders may be amended or revised by each plant physician and should bear his signature of approval before they become effec tive. The orders cover emergency procedure and routine care of the various types of industrial injuries with special emphasis on fracture and eye in juries, non-occupntional and minor illnesses, dermatitis, and pregnancy. 1238 The Psvchifltrij^Araroacfc in Industrial Nursing. C.A. Bonner. Ind. Nursing, 4, 12-14 (Sept., 1945) "Today the industrial nurse is regarded as an essential and integral member of the well-organized industrial set-up." There are not enough psychiatrists to provide direct care for the so-called average normal person in industry, but "an industrial nurse, blessed with good sound common sense and elementary knowledge of psychiatric causes and effects may be a very valuable factor in the development of morale" among plant workers. In dealing with personality problems, an approach should be made along four lines: n thorough physical examination; an understanding of the personality of the individual; an inves tigation of the home situation; and an analysis of the job situation in terms of the worker end his adaptability to the particular type of work that he is doing. In all of these investigations the nurse is invaluable. 1239 Accidents bv Anv Other Name. Henry Ross. Chem. and Met. Eng., 52, 96-99 (July, 1945) The author, writing under a nom de plume, tells about a long established com pany that, despite a. good safety record and a competent medical staff, still lost, by early sickness and death, many comparatively young men in responsible positions. Worry among executives is believed to have played a large part in bringing about these illnesses. A psychiatrist could have aided most of the men end saved many of their lives. The remedy lies in the employment of an industrial psychiatrist for the plant. 1290 Uses and Value of Industrial Vital Statistics. Ruth R. Puffer. Am. J. Pub. Health, 35, 553-558 (June, 1945) Statisticians would be of real value in industric-1 hygiene activities, both to provide data for the definition of the health problem at hand and to study the common causes of illness in the general population as they affect industry. The author recommends a study of all absences of one calendar day or longer. -- J.I.H.&T. 03118601 08SU00-88NM HWBB-0011581 Industrial Hygiene Digest - 23 December, 1945 Industrial Relations, Personnel 1291 Responsibilities of Employers to Professional Employees.

F.A. Magoun. Personnel, 2Z, 109 113 (Sept., 1945) A good personnel director is not content to remain just an employment manager but will see in his job the opportunity to be e. staff officer, adviser and policymaker in his field. Under his jurisdiction come all sorts of problems which he must understand and communicate to executives, foremen rnd workmen, end bring to them Hie psychological requirements for cooperation. His reel function is to diagnose and safeguard the mental health of the organization, achieving his effectiveness more by persuasion than by authority. 1293 The Coming Age of Industrial ..iedicine. L.G. Rowntree. J.A.M.A., 129. 595 600 (Oct. 27, 1945) The war has taught us the value nd the problems of the health and fitness of individurls. Postwar plans stress the need in medical and dental schools for organised research in industrial health, and for more extensive instruction in hygiene, toxicology, industrial medicine and traumatic surgery. There is need for basic training progrsm/SSE industrial health personnel. There must be a closer cooperation vith labor and with management to give the individual workman and the rural communities more adequate health services and hospitals, and better health education programs.

Med., 14, 649 (Aug., 1945) In the manufacture of Timken tapered roller bearings, it is essential that the diameter of various parts be ground to within very fine dimensions of the . . specified sizes, and in Hie final inspection, the rejection of those parts over nd under specification is controlled by different colored lights. The Timken Roller Bearing Company has invented a-sound detector which does the same work, thus enabling blind operators to complete this very fine inspection by means of their ears. File testing is another job accomplished by the blind where the operator differentiates by rtfeel" as to the hardness or softness of steel for rejection or pass. It has been found that blind employees can per form about 80 percent ss efficient work as the regular employee, and the re sults observed are gratifying to those instrumental in the rehabilitation of the blind by developing new methods. 03118602 If--d C=fl Industrial Hygiene Digest - 24 December, 1945 in 1295 ftld to Physically Handicapped* A.B.

He says that most per sonnel men seem unaware of the deep transformation wrougit in the attitudes of their former employees by army life, and of the new philosophy *nd work habits soldiers have acquired. He emphasizes three ways in which industry can and should help every veteran, namely: (l) the serviceman must be con vinced that private industry sincerely wants to help him get a start back in civilian life at a good job; (2) industry must impress upon him that the only thing which can be offered him is the opportunity to work, and that he, him self, must prove his worth; (5) he must be taught again how to work and how to regain his initiative and the desire to do a good job. 03118G03 (o Cu--oi & Li---- J 00 J---- 1 G=fl m oo un r-- Industrial Hygiene Digest - 25 December, 1945 S o 1300 Medical Problems of the.

Deafhess becomes a special problem because it carries with it a large number of psy chological factors: the deaf tend to minimize their handicaps, to develop un warranted suspicions, to misinterpret sounds and to develop deterioration of speech. A fully rounded program should be developed in which psychological and employment factors are considered. The cause and degree of hearing loss should be ascertained by medical examination and proper hearing aids selected. Lip-reading and speech correction should be a part of the program.

Med., 14, 769-794 (Oct., 1945) 1. During the past year there has been no significant change in the physical and mental make-up of individuals comprising the veteran group as a whole in our experience. (A) There has been a slight increase in the numbe# of veterans who have been wounded in combat. At present they comprise 1.2# of our entire group. Some two-thirds of our total veteran group have Certified Disability Discharges. (B) The so-called neuropsychiatric group have not been a problem. They comprise approximately 50% of the Certified Disability Discharges in our group. In our experience, 97% of the veterans were graded by their foremen as satisfactory (or better) in work performance. (C) Evidences of adjustment difficulties are more coranon during the first six months of employment and decrease rapidly thereafter. (D) About 20% of veterans in our group are over 53 years of age, 50% between 30 and 38, and 50% between 18 and 30. 2. Disa bility as it appeared in our veteran group did not decrease productive effi ciency. (A) A system of job placement respecting disabilities is beneficial mutually to employee and to employer. (B) Medical details of physical condi tions can be kept confidential. (C) 17% of veterans with Certified Disability Discharges do not acknowledge the disability present. This may. lead to im proper job placement if the disability is not detected on physical examination. 3. The rate of turnover in our veteran group per month is somewhat less than in our civilian group. (A) Since the War Manpower Commission no longer insists on a Certificate of Availability for veterans, there have been few disciplin ary discharges. (B) In our group, disability (mental or physical) has not been a casual factor in disciplinary discharge cases. 4. Employers should have a list of official local agencies which assist veterans. 5. In our experience, the seriously incapacitated veterans have not yet appeared as applicants for jobs (up to April. 1945) in any significant numbers. 6. A policy of greater consideration, but not of greater privilege, has so far proved satisfactory to both management and the veteran. -- Authors* summary. 03118604 Industrie!

Med., ,14, 691-697 (Sept., 1945) The results of a tuberculosis survey covering 25,676 industrial workers showed the incidence of significant tuberculosis was 1.08% and that of active pulmon ary tuberculosis was 0.22%. In the age group, 45 years and older, the incidence was about four times that in the 16 to 44 year-old group. In plrnts using chest X-rays in their pre-c-mployment examinations the incidence was about half of that in the plants not using X-ray? in photofluorography the roll film camera was found to have the advantage of speeding up mass surveys. The importance of in dustrial surveys from the standpoint of community welfare has been shown, con sidering the groups surveyed as sempling, the case incidence of active pulmonary tuberculosis in the population group of 15 years end older was estimated as 0.52% in m industrial community of over 100,000 people. It is suggested that tuberculosis surveys of the industrial plants be repeated regularly by the tu berculosis agencies of the community, at no expense of the employees or manage ment; and that "house organs" published by various plants be better utilized for health education among the workers. A more direct stand on the part of national labor organizations in favor of such surveys could lead to a greater participation of organized labor and thus to its better health protection. -- From authorsf summary. 1306 The.-Role of a Sanitarian - In an industrial Hygiene Program. A.L. Koven and W.S. Johnson. Ind. Med., 14, 704-707 (Sept., 1945) The term "srnitarian" may denote either an engineer, or one who has been trained in a science related to sanitation, or an inspector, depending on in dividual training, aptitude and application. It reviews the dangerous results which arise from careless sanitary conditions and habits in industrial plants, thus showing the important role a sanitarian plays in health education. There is a strong movement toward the recognition of industrial sanitation as a prime ingredient in industrial operations. 1509 The Epidtttntnlngy of Influenza in Industrial Workers. L.K. Khotsianov. Gigiena i Sanitariya. No. 4-5, pp. 8-15 (1944) (Russian) . . Figures arc given for the incidence of influenza in 19 different Industries over the period 1925-1939, comprising 9,256,000 cases. Some industries show a much greater incidence than others, end this difference remains constant from year to year, while in all industries tne number of cases has shown a gradual increase during the period studied. The variation in incidence among the in dustries has been attributed to variation in meteorological factors, but the author considers that other factors besides weather are responsible, such as overcrowding and deficient ventilation of factories in winter. Climatic fac tors cannot explain different incidence in two industries at a time when they are equally unfavorable in both cases. Alleged low incidences in certain in dustries have been attributed to the beneficial effect of radiation (arc-welding 03118606 Industrial Hygiene Digest - 28 December, 1945 > 00 or inhalation of chemicals (chlorine, phenol, etc.), but there is a low inci dence of influenza in other industries in which these factors are absent. Th^a author quotes figures for the morbidity rate among chemical workers in whom there is no significant difference free that seen in other industries. He coo siders that adaptability of the heat-regulating mechanism of the body plays are* important part in lessening the susceptibility to influenza; thus, the inciderfEe is lower in iron-miners, and in agricultural end other outdoor workers. Indus tries where workers are most crowded d*ow the highest incidence, and vice versa; the low incidence in the metallurgical industry is more likely to be due to the absence of overcrowding than to the protective effects of radiation. -- Bull. Hyg. 1510 Public Health in an Industrial Area. State Department of Health, R.H. Hiley, Director. Maryland Health Bull., 17, 58-60 (Sept., 1945) The Baltimore County Health Department, the County Medical Association, the Glenn l>. Martin Company and the Federal Government hove successfully cooperated in a health program for the industrial population in the Middle River area. After more than four years of intensive activity they now have well ordered housing with adequate sanitation, tuberculosis and preschool clinics, day nur series and a nursery school; they control the care and handling of milk and other food products; there is ?. small infirmary for emergency care with hospi talization available in Baltimore City for more serious or longer cases; there is a "loan closet" well stocked with blankets, pillows and sickroom needs, which may be borrowed at 25^ per week. Community centers provide wholesome recreation, thus contributing to the mental health. Favorable environmental conditions now prevail and health is maintained at a high level. Accident Prevention 1311 Inflammability of Natural Gao; Effect of Preagura Ttnem Llartte. G.W. Jones and R.E. Kennedy. U.S. Bur. Mines, Rept. Invest. No. 3798. 15 pp. (Feb., 1945) This report gives the results of tests made to determine the effect of increased and reduced pressure upon the limits of of natural gas--air mix tures. When natural gas-air mixtures are confined at pressures below atmos pheric, the limits of inflammability are virtually the some as at atmospheric pressure. As the pressures are reduced below atmospheric, the mixtures become more difficult to ignite; however, if a suitable source of ignition is employed, the limits of inflammability ore as wide at three pounds per square inch abac- r lute as they ore at atmospheric pressure. Natural gas-air mixtures are able to propagate flames when ignited at very low pressures. Certain mixtures were found to be inflammable at pressures as low as 1.0 pound per square abso lute. The lower limits of inflammability of natural gas-air mixtures are vir tually independent of the pressure over the pressure range extending from atmos pheric to 500 pounds per square inch. The upper limit of iwfi 1 j ty is affected markedly by increased pressures, rising as the initial pressure on the mixture increases. This effect widens the limits of inflammability as the pres sure increases. At 1QP pounds pressure, the range of iirrtnmmaMlIty is about 1.5 times that at atmospheric pressure; at 200 pounds, 1.9; at 800 pousds,2.7; and at 350 pounds pressure, 3.5 times that at atmospheric pressure. It is tfww seen that when natural gas-air mixtures are compressed, the range of inflamma bility is widened, and hazards attending their use are increased 03118607 HWBB-0011587 Industrial Hygiene Digest - 29 December, 1945 The calculated limits of typical natural gases are given, from which, by com parison of these with the composition of the natural gas employed in a given process, the explosion hazards may be estimated* -- Authors' conclusions. 1312 Microseismic Method of Predicting Rock Failure in Underground Mining.__ Part 1. General Method. L. Obert and If. Duvall. U.S. Bur. Mines, Rept. Invest. No, 3797. 7 pp. (Feb., 1945) All rock formations show microseismic activity when subject to stresses ap proaching the strength of the rock. There is a rapid increase of 10 to 100 fold in the microseismic rate immediately before failure. The larger the af fected area, the longer of increasing microseismic activity before failure. These microseisms or vibrations can be detected by suitable apparatus, include a geophone which is inserted into a deep drill-hole, amplifiers, and recording apparatus. A skilled operator can detect and locate the microseismic distur bances, two months' training has often boon sufficient. 1313 Blazing Hazards in Strip Mines. Ad jacent to Underground Workings. J.J. Forbes and H.F. Weaver. U.S. Bur. Mines, Inf. Circ. No. 7296 . 5 pp. (Oct., 1944) Precautions necessary for prevention of injury from blasting in strip mines are stated. The principal hazard is the penetration of poisonous gases into the underground mines. Some typical accidents are described. 1314 C&al-Mine Explosions and Coal- and Metal-Mine Firea in the Statea Paying the. Fiscal Year Ended June 50. 1944. D. Harrington and W.J. Fene. U.S. Bur. Minos, Inf. Circ. No. 7330* 35 pp. (Aug., 1945) Both fires and explosions have been decreasing in frequency over a period of years. There was only one major coal-mine fire disaster during the year, but ^2 fires and 23 explosions occurred in that period. Causes ore analyzed and classified. Electrical sparks, smoking and lighting safety lamps with matches are among the chief causes. Improved ventilation would hove been a corrective in most of these cases. - - gome explosions occurred where rock dusting was used, but in most cases 'there was no dusting or it was inadequate. 1315 Surface Storage of Explosives. D. Harrington and R.G. Warnicke. U.S. Bor. Mines, Inf. Circ. No. 7307. 16 pp. (Feb., 1945) Of many thousand storages of explosives inspected during the war, not more than 10$ were found Safe or efficient, and great carelessness was often shown in choosing storage places, often in the open, sometimes in houses or dieds, often with little protection against theft. A number of rules for safe storage ore given, with sectional drawings of typical magazines. 1316 Destruction of Damaged. Deteriorated or Unwanted Commercial Explosives. R.D. o o Leitch and P.R. Moyer. U.Sl Bur. Mines, Inf. Circ. No. 7335. 6 pp. (Aug. ,1945) Directions are given-for disposal of waste dynamite, black powder, smokeless powder, detonators, electric squibs, safety fuse and primacord. Burning is the method recommended in most cases. The question of disposal of nitrogly cerine rnd other materials not included should be referred to the manufacturer, tut directions for washing nitroglycerine from magazine floors are included. c=a 03118608 C=3 Absenteeism 1504 statistics 1505 Accident statistics Book Review 1222 Air analysis organic halogens 1227 Air-borne, infections control of 1229 Aircraft assembly control of hazards in 1228 Aluminum prophylaxis 1273 Aluminum therapy in silicosis 1274 Analysis, photometric of certain metals 1224 Anthrax, experimental penicillin treatment 1256 exposure in arsphena- mine manufacture 1257 Asbestos possible substitute 1239 Atmospheric pollution study and control 1234 Aviators bends in 1253 Book reviegg-_and_ notices 1221-1222-1223 Burns 1272 new dressing for 1271 Cancer, traumatic 1255 Carbon monoxide poiaoning blood changes in 1251 Carbon tetrachloride acute poisoning from 1250 Case histories guide to recording 1282 Chlar?,f.OT safe handling and stor age 1249 D.D.T. case of poisoning 1243 fate of in body 1246 medical and public health importance 1245 toxicity of 1244 INDEX (December, 1945) Dermatitis acute mildew agents 1270 . cutting oil 1268 cutting tools 1267 rubber gas mask 1269 Dust diseases results ?;ith new expo sure apparatus 1240 Electric .shock secondary circulatory reactions 1264 Electrostatic air fil ters design and operating requirements 1232 Ethvlene dichloride health and accident hazards 1247 in gas mixtures effect of pressure 1311 Explosives disposal of 1316 safe storage of 1515 OaB poisoning in mine fires 1315 Gloves chemically resistant 1251 bent . effect of 1265 Industrial ar,o.sa public health services in 1310 Industrial dental program 1286 Industrial health educa tion 1277-1284 Industrial medical ser vice by group effort 1285 : evaluation of . 1278 Industrial medical records uses of 1214 Industrial medicine educational needs 1295 future of 1281 postgraduate course in Book Review 1223 oo 00 un Industrial nurres --< 69 22 I jg psychiatric services!* 1298 * standing orders for 1287 Industrial_ psvchiatrist need for 1289 Industrie l__S8iiitatlon. 1398 Industrial ..vital statis tics 1290 Industrial wounds added infection in 1283 Influenza epidemiology of 1309 Iron foundry health hazards in 1241 Iron and steel foundry health examination in 1275 Mental hygiene program for Industry 1280 JttSEOUS determination in bio logical materials 1226 Methvl chloride intoxication from and treatment 1248 Mine explosions in P.S. during 1944 Nutrition 1314 review of Nystagmus 1266 demonstration of 1262 unusual forms of 1261 Occupational Jiisccse con trol .
