Preface Hie first edition of this guide to the hazards of occiipL.^.ls and to the symptoms of the diseases tiny cause was intended primarily to aid the medical examiners of the Metropolitan Life IiisurencaCo. in tlte discovery of impairments among applicants for insurance. Tlte pamphlet soon attracted the attention of others not immediately interested in insurance medical examinations. Industrial physicians, directors of compensation boards, factory inspectors, safety engi neers, industrial rehabilitation agents, faculties of medical colleges, sud. most important of all. general practitioners of medicine, have made a call for this work and have expressed their approval of it. SubBequcnt edilions have been equally well received. It has been repro duced either in whole or in part in a number of works by authorities 011 the subject of industrial hygiene. The present publication is a complete revision of Bulletin No. 682 of the United States Bureau of Labor Statistics, issued in 1033 under the same title. The authors are convinced by tlmir experience with Uiese earlier editions that this bulletin lias served s useful purpose, and that there is a, vital need for s compilation of this kina, which makes readily available the most recent finding? qp industrial hacards to those win have not the time for a thorough study. Obviously, the extension of the compensation laws of tin several States to include all occupa tional diseases, or an increasing numlwr of them, has made it neces sary for physicians to be familiar with at least their most common symptoms. Those who may wish to look further into the causes and effects of specific hasards will find detailed information in the sources referred to in the Iasi section. The two decades which have passed since the first edition of this bulletin was prepared have been years of tremendous expansion in Ilia field of indukrial hygiene. It has come to be recognised as an important branch of industrial management in which industrialists, physicians, engineers, chemists, laboretoiy technicians, statisticians, lidior taw administrators, workmen's compensation officials, and factory inspectors cooperate in the discovery of hazards, the nature of the injuries they cause, and in working out measures for their preven tion. Tiny have been years noteworthy for the luge number of scientific investigations undertaken lure and abroad to determine the causes of ill health among workmen and the effects of exposure to specific hazards.. As a result of newer findings, we have had to revise many of our views on the effects of specinO' industrial exposures. Our idea that dusts, for example^ were injurious in proportion to tlie hardness and sharpness of their particles, lias been drawn to bo erroneous. It is now tald that duBts are injurious in proportion to tho amount of free silica or the uinount of asbestos they contain. Our knowledge of the effects of many oilier hazards, long recognized as injurious, lias been enhanced, and In addition a wealth of informs- THIS DOCUMENT WAS NOT A RECORD OF PPG INDUSTRIES. INC. DIO NOi COME FROM IT'S FILES AND CANNOT BE AUTHENTICATED BY PPG INDUSTRIES* INC. 2234 -------- ------- tion his been supplied on the effects of Important new hazards, notably the volatile solvents and chemicals employed in the tnanii* lecture of synthetic) resins, to mention only two. In preparing this, the fourth edition of the pamphlet, the authors have endeavored to present the mast recent thought mi occupational hazards expressed in this vast literature on industrial hygiene. They realize full well the inadequacy of ezisting knowledge of the effects of many industrial hazards, and the amount of scientifio research necessary before these effects are definitely known. They have not presumed to attempt to settle controversial questions, nor have they attempted Ut set up standards for llte guidance of those whose responsibility it is to pan upon claims for compensation or damages. The symptoms, conditions, or diseases cited are those which are reported in the best works available on the several hazards. They have not been listed in the order of their importance, and many are perhaps of rather rare occurrence. Similarly, the occupations and Industries listed are those In wliich the hazard may be present, and not necessarily those in which specific coses of injury have occurred. It sliould be recognized that even where poisons or other hazards are present the chances of injury may be slight. Some industries today, due to the excellence of the preventive measures they have instituted, ere manufacturing or handling eztremely toxic materials with virtually no danger to the workmen. There is every reason to believe that most, if not all, plants could eliminate the hazard of poisoning if management and employees worked together toward that end and this may be said of many other hazards. A word of caution sliould be given to the layintn against the use of the materiel presented here for self-diagnosis or for diagnosing the illness of others. That is a practice fraught with the graven danger. The only people competent to make a diagnosis are physi cians. They should be consulted without delay whenever there are signs or symptoms of ill liealtb. The hazards covered now include "abnormalities of air pressure;1* "abnormalities of temperature;" "dampness;" "defective illumination;* "dust;" "infections;" "radiant energy;" "repeated motion, pressure, shock, etc.;" the "poisons;" end "dermatoses.* The number of poisonous substances considered has been increased from 94 to 128. The number of occupations listed baa been increased to approximately 1,100. The authors desire to acknowledge their indebtedness to the mem bers of the medics! profession of the United Stales and Canada who have so graciously received tlie previous editions and wlio have so enthusiastically cooperated in extending its scope. It would bo im practicable to make, personal acknowledgment of all the esaistamw which has been received in preparing this revision.

OCCUPATION HAZARDS AND DIAGnM^A SIGNS A Guide To impairment* To Be Looked For lit \ \ |ts \! Introduction Many occupations have injurious effects on tlie physical condition of those enmiged in them. The health of those who work with tlie poisons, sucu as lead, arsenic, mercury, picrie acid, and so forth, or those who are exposed for Ions periods to dust, heat, humidity, or to the^ infectious materials, may be impaired seriously as tlie result of tlieir work. Tlie occu|wtion is now recognised as of tin very first importance as a factor in the causation of disability and even of death. We see this reflected in tin frequent revisions of compensa tion laws to include an increasing number of occupational diseases. It is now generally recognised that patients come to physicians with Kins and comnlaints of an indefinite character, but which in many stances are tin effects of their occupation. With their attention directed to occupation as a possible factor, physicians are able to diagnose s great many obqcure cases which previously had puxxled even tin most competent 'clinicians. In this way they discover a great many more cases of disease of occupational origin than had before been thought possible. Tlie medical examiner sliould therefore be very careful to see if any of the usual diagnostic signs of poisoning, oust, heat, or other hazards which are known to be inherent in occupations are in evi dence among his patients, where no other explanation of the case is readily available. In the cam of those exposed to lead, such as paint mixers, painters, and so forth, the blue line on the gum, tlie pale, sallow appearance, and tlie trembling fingers, are significant as indi cations of chronio lead poisoning, and the physician sliould look for these Bigns. Physical symptoms and conditions which ordinarily might be passed by in this way become very important if tiiey point to the possible effect of tlie occupation. This handbook has been prepared to aid physicians in general firoctice, industrial hygienists, safety engineers, snd others who corns nto close professional contact witli those who are engaged In indus trial processes. Nine niajor hazards of employment are listed! namely. HabnonnaUties of air pressure"; ''abnormalities of tempera ture"; "dampness": "defective illumination"; "durt"; "infections"; "radiant energy"; "repeated motion, pressure, or shock"; and th "poisons." A separate section of the bulletin is devoted to a diecuiwion of the dermatoses. Long exposure to any of them may leave definite physical signs which the medical examiner can discover if he wiA look for them. To aid him in detecting the hazards and * 2 OCCUPATION HAZARDS AND DiAUNUbHU tMUr. their effects on the worker, tw lists are presented. The first con* slste of the m re common occupations in which hazards maj be found, arranged alphabetically; the second consists of hazards, together with their effects or symptoms, as well as the occupations affected. Q CO After each occupation in the first list is a reference in code to the -- LU particular hazard in the Becond list The capital letters after each O Zj occupation, A, B, C, and. bo forth, refer to the general hazard. The arabtc numerals signify the particular hazard, as E 1, organic dust; B 2, inorganic dust containing free silica. The following example will bIiow how this guide may be of value to lb general practitioner; A men who works aa a presser, suffering o :SZ from continuous headaches, visits his physician. The tatter can find no cause for the patient's illness. The patient shows no signs of dig* esse other then the subjective symptoms which he describes. Per haps the physician will recommend an examination of ths subject's eyes, ears, and Binuses, which will prove negative. A correct diag nosis In a puzzling such as this is much easier to determine when the occupation is ascertained and this guide is utilized. Alongside of Sj 'pressers* in the Alphabetical List of Occupations, the physician hide the symbols H, J 27. "H" represents the hazard "repeated ' o Vnotion, pressure, shock"; "J" the hazard "poisons"; and 27 the par ili ticular hazard "carbon monoxide." Upon looking up the symptoms f tltess hazards in the second list, he finds that carbon monoxide Sreduces headache. In such a case an effort should be made to iscover if this poison exists as a hazard in the plant where the i-- S-- oo patient ie employed. The remedy consists in the removal of the etiological factor---the specific poison. The following procedure is therefore recommended: The medical examiner or physician should ascertain the occupation of the person undergoing examination. He should then look for it in the Alphabeti cal List of Occupations (p. 4). If found there, it is possible that the person has been exposed to, and possibly is suffering from the effects of, some hazard of hi* occupation.. ,Tne numerals will indicate the particular hazards of die occupation. The physician should then make special effort to discover the symptoms or Bigns referred to in die second list. His examination is in this way made more illumi nating. Physicians not specialists in occupational hygiene can thus learn to detect the effects of industry and, conversely, can eliminate the occupation as the cause when certain symptoms are observed which do not fit the usually observed effects of the occupation. Medical examiners should remember that itto often necessary to keep In mind not onto the present occupation but former ones as well. Per sons suffering from certain ailments may no longer be engaged in the Industry which was responsible for their condition. Bui careful in quiry into their occupational history will sometimes result in the re- fHing of an occupation the effects of which are clearly those from h the patient is suffering. The medical profession must give V national findings greater weight in forming their judgments re garding physical conditions and in diagnosing and treating disease. It is hoped in this way that the medical profession will become more and more acquainted with occupational diseases end help in the move- ment to discover and eliminate cases thereof. In our country it is still tru that very large numbers of working people are constantly exposed to serious occupational hazards snd suffer, often unnecessarily, very seriously, from the effects of such exposure. Occupational disease haz ards can be brought under control if management and men work to gether. Hie greater interest of medical practitioners will help mate rially in tlie campaign of prevention.. Medical schools can aid greatly \Z\in bringing about this result by giving due weight to the subject in their courses of Btudy. Already the form and content of tills pamphlet . have recommended it to several schools, which report its value. In tli 0I i to i same way, plant executives anil safety engineers must take cognizance ! | er. l of die existence of these occupational discuses and look carefully into 1 I -- i their own establishments to see to what degree the processes of their shops are devoid of the dangers which are usually associated with in dustrial operations. Factory inspectors, labor officials, and workmen's compensation boards will find it helpful in inspecting and evaluating the hazards of numerous industries. Many hazards may be revealed Is! icQi 1 ca i !-! which they have not known were associated with tlie processes of manufacture, and of which tlie employers themselves hav been ' ignorant. Those concerned with industrial rehabilitation aliould find this bulletin an aid In selecting occupations for those with arrested cases of tuberculous or other organic diseases. All of the foregoing comments receive a special emphasis st this time due to the general defense program. One result of tlie enor mously increased manufacture of munitions of all kinds is the use of many chemicals about which little or nothing is knownt and many of which are entirely new. Furthermore, the lengthening of the hours of work and of Ilia number ftf work days in the week and tlie added stress of production carry with them a likelihood of aggra vation of occupational hazards so that hazards which are ordinarily of minor importance may become serious under the stress of war time conditions.

Compressed Air (Increased Atmospheric Pressure) l In building tunnels, laying deeii foundations (or large buildings,o and bo forth, it is often necessary for tlie work to be carried on under increased air pressure in order to prevent ilia entrance of wuter into tk excavations. After the workers enter the compression chamber or u!ockn Urn pressure of tlie air in tho compartment is increased gradually and at short intervals. Tito And sensation of compression is felt on (he eardrums, which may be relieved by the act of swallow ing. If the air is too quickly compressed, hemorrhage may occur. The greater part of the danger of working in compressed sir lies in liasty decompression. While under compression the blood and tissue 1Alices dissolve an increased amount of air, the gases of which are re eased when the pressure is suddenly decreased. The bubbles of ni trogen tliUB formed cut off the blood Bupply from various parts of tlie body by blocking up the capillaries.

Exposure to decreased atmospherlo (pressure has a profound effect on ueallh. 43- 17 16 OCCUPATION HAZARDS AND DIAGNOSTIC BIGN8 The physiologic*) changes which occur are chiefly due to oxygen went (anoxia), and tlie term used fur the resulting condition is "Altitude sickness." It may be acute, due to rapid ascent or prolonged stay at high altitude, or chronic, due to the cumulative effect of repeated prolonged exposures to minor degrees of oxygen want. Furthermore, as the external air pressure on tin body decreases, the internal pressure must decrease correspondingly if the body is not to burst; eot given sufficiently extreme conditions of decreased pressure and rapiu ascent, the internal gases of the body will oxnand and eventually, at altitudes of 30,000 feet or over, dissolved airbubbles will form in the blood vessels and tissues as in compressed air illness ("the bends"). "Aeroembolism" is tlte term given to tltis condition in aviation medicine, and normal individuals vary greatly in suscep tibility, so that it may occur at lower altitudes. Disturbances of the middle ear are common among flying personnel' due to rapid changes in altitude and pressure.. A rapid dive with negative pressure on the eustacliiun tube prohibiting ita opening may cause the drum to rupture. Tlte lowered partial pressure of oxygen in the inhaled air at high altitudes hss also a dangerous indirect effect in that it renders the individusl more susceptible to carbon-monoxide1 gus should this be present in the pilot or passenger compartment. Low concentrations which would be considered safe at normal atmospheria pressure are capable of causing anoxemia and asphyxia at high altitudes due to the progressively decreasing oaygen saturation of die blood under Uiese conditions. The discussion in this section is based upon the exhaustive treatment of the subject given in the work by Dipt. Harry O. Armstrong entitled "Principles and Practice of Aviation Medicine," Williams & Wilkins, 1939. Anyone interested in any phusu of thu Increasingly important subject will And this work indispensuble.

Abnormalities of Temperature and Humidity Exposure to environmental temperature beyond the action of the body* thermostatic control primarily results in disturbances of tlto circulatory system. The cutaneous circuit! I ion responds to licat slimu-. lation in the skin by increasing tlie blood Dow through the cujiillaries. The capillaries, resjjondiiig to a reflex action of the nerves in tho skin, dilate and induco.tho flow of a greater volumo of blood through the cutaneous circulation. Cold, on the oilier hand, constricts the blood vessels of the skin, causing a diminished blood supply through1 the cutaneous circulation and not infrequently a serious congestion of* the internal organs. Abrupt changes of temperatures, from extreme heat to cooler temperatures or vico versa, are of frequent occurrence, and are a contributory cuuse of respiratory diseases. Extremes of tem perature may produce acute symptoms in tho body directly attributable to tlie teniiiemture. Thus, exposure to excessively high lemjwrutures results in heat exhaustion, heat stroke, or in heat cram{is; to exces sively low temperatures in frostbite or gangrene and death. i Tlie relative humidity is an ini|M>itant rector to consider in connec tion with temperature. It is contended that a low relative humidity tendS'to dry up the mucous membranes of the nose and throat, thus lowering the resistance of these organs to infection. An excessively high relative humidity, ou the other hand, is undesirable because of ita interference with the normal evaporation of moisture from tlie skin. Under extreme conditions of high temperatures and high relative hu midities there occurs e marked Increase in the pulse rate, systolic blood pressure, and in the body teinperalure. Low temperatures and high relative humidities have tlie effect of undermining the general vitality of tho organism, weakening its resistance to diseases of the respiratory passages, and to neuralgia and rheumatic affections. Willi th above data in mind, abnormalities of teni|enitura have been classified under two headings, namely, "Sudden variations of temperature." and "Heat." "Extreme cold" has not been listed as a distinct hazard, because tlte factor of occupational exposure is readily recognized and the effects well known. It is evident that the occupations listed in the division "Heat" are exposed not only to the danger of the direct action of the high temperatures but sIbo to the hazard, "Sudden variations of tem perature." The prevention of diseases due to exjmsure to extremes of tempera ture consists in tlie avoidance or niltigution of such exposure as far as practicable. In recent years, ventilation, refrigeration, and air-con ditioning have received much attention, and installations of machinery to control atmospherlo conditions are becoming more and more com mon. Protective clothing and insulating methods can mitigate haxards of abnormal temperatures. The me of salt as a preventive of heat cramps hss become a standardized procedure. Those who have a need for technical dataon these subjects will find much of value in tlte chapter on "Lighting and Atmospheric Control" by Dr. William J.

Defective Illumination a Defective illumination, characterized by insufficient quantity of light,^lure (light out of place), uiumitahility of color, anil improper diffusion and distribution of light, i tho cause of eye fatigue, head ache, dizziness, and errors of refraction. Miners* nystagmus, a con dition in which tin eyeball acquires a peculiar involuntary oscillatory movement, is attributed to tho effects of iuHuflieicitt illuntiiml ion. This , disease is very common among. British miners, but ap)tarently is not found to any extent among American niincra. The explanation for the favorable, situation of the American milter probably lies in the better I illumination of the American mines. Not only is defective illumina-1 lion the cause of these Berious .ImjMiirmcnts of vision but it is an im- i portant factor in induced working efficiency in industry generally, uml it ib a very frequent cause of industrial accidents. Tim hazard of dufeclivo illumination is not limited to any single industry or group of industries. It may be present in uny plant. Men enguged in occupations requiring closu, Duo work, such as jewelers, en gravers, clerks, and mail sorteni, are especially likely to suffer from exposure to this haunl. It is a comparatively simple matter to provide for all tho require ments for properly illuminating workplaces in some industries, while in others the advice of illuminating engineers is required.

C 22 OCCUPATION HAZARDS AND DIAGNOSTIC SIGNS Poisonous dusts ire not considered in this section but under tbeir appropriate headings relating to their composition. For practical purposes industrial dusts are divided into two classes, organic and inorganic. ORQANIO DUST Organic dusts contain carbon and are largely derived Iran sub stances of animal and plant* origin. Examples of these are textile dusts, flour, sugar, wood, leather, and feathers. Organic dusts may irritate the skin, causing an occupational dcrmutitis or may irritute the conjunctiva. Many, if not most, organic dusts may cause an allergic reaction in some persons. When present in very large quan tity, any organic dust may cause irritation of the upper air passages. Some woods may also cause skin irritation, notably Brazil wood, satin- wood, teak, soma mahoganies, cocobolo, California redwood. Organic ditsls do not cause pneumoconiosis or pulmonary fibrosis of a specific disabling nature. The particles of many types of organic dusts are not of the size or shape to permit them to penetrate to the lung tissue and those which do gain entrance into tiie body are ab sorbed. Coal 1b an organic dust, but on account of its origin la some times classed with the mineral dusts. CWI dust does get into the lungs, causes pigmentation, and may stimulate the production of fibrous tissue but will not produce a disabling pneumoconiosis The "miners' asthma** of anthracite miners has been shown to be in fact s silicosis, modified by the presence of coat dust along with the silica, and is properly termed antliraco-ailicosis. INORGANIC DUST Inorganic Industrial dusts are mostly metallic and mineral. Of all the various types of such dusts, only those containing "free** or \mcoinbined tilica will produce the specific pneumoconiosis known as silicosis. Other inorganic dusts may cause some pulmonary fibrosis of s benign or nondisabling character. Hie action of silica dust upon the lunga is probably chemical, and the dust particles producing the reaction are mostly those from one-half to three microns in diameter. The reaction of silica is the production of nodules, distributed throughout both lungs, producing a characteristic appearance on the X-ray film. Another effect of silica is to stimulate tubercle, infection and Bevere cases of silicosis frequently die with tuberculosis. Dusts containing silica in combined form do not cause silicosis. However, one Bitch dust, ariiestos, a magnesium silicate, will produce a characteristic fibrosis. This is unite different in its pathology from silicosis, and has a characteristic "ground glass'' appearance on X-ray film. . Animal experimentation indicates that the action of asbestos is probably mechanical, since it cannot bo produced in other than the pulmonary tissue. Asbestosis may cause disability, and a few fatal cases have been recorded, but in those cases showing marked disability, thcr organic disease is usually also present. The control and prevention of silicosis and asbestosis depends on both medical and engineering supervision. . Periodic X-ray examina tion of workmen exposed to these dusts is essential.

Much has been learned concerning adequate measures for the pro lection of workers exposed to X-rays snd radioactive substances mice ( the early days of their discovery, when many pioueera in medical treatment with these new agencies suffered severe mutilating disabili ties because of their unmitigated exposure. Protective measures today have been worked out in considerable detail for the variety of condi tions met with.

Ultraviolet tad Infrared Rays Ultraviolet and infrared rays are an industrial hazard in a number of occupations where there is exposure to excessive radiance. Welders end cutters especially an exposed to ultraviolet rays; furnacemen and other workers around molten metal and glass, to infrared rays. Al though we cannot see ultraviolet snd infrared rays, they an very active and powerful and are usually coexistent with excessive radiance. Ultraviolet rays are chemical In their action, and cause intense irritation of the eyes and burns of the skin, similar to sunburn. Snow blindness, desert blindness, and the "eye flashes** of welders are one and the same condition, all due to the action of ultraviolet rays upon the eye; their effects can be very painful and cause disability for sev eral days, though usually they do not cnuBe permanent damage. Infrared rays act upon the eyes simply as heat, but muy cause per manent damage (cataract). _ There is little definite evidence that weld'"f bas caused cataract, similar to glussblower*s cataract, but it is bable that prolonged exposure to infrared rays may cause haziness V dm cornea. The injurious effects resulting, from excessive light due to defective illumination are not consideredliere. but treated as a separate hazard. St* Hazard D.

Repeated Motion, Pressure, Shock, tc. Under this heading are included those conditions which are causeu by continuous repetition of movements, pressure, or blows peculiar to many occupations. This section is not concerned with the neurasthenia phenomena following accidental injuries, commonly referred to as traumatic neurosis. Everyone ib familiar with the muscular strain experienced in per forming for the first time some exercise, such as rowing, long walking, and so forth. Men newly introduced into a process requiring such repeated action are affected similarly but often much more severely, so as to disable them tem|rarily for the particular job. When the body is Bubiected to constant pressure or rejwated shocks such as are encountered in working with pneumatic tools or when muscles are used for a long period under conditions of severe strain, there may result tenosynovitis or bursitis. In the use of pneumatic tools, due to the rojteatcd shocks or vibration, there ny occur also marked vasomotor changes with a characteristic condition known as "dead fingers.** Ex posure to vibrations may also cause changes in bone structure. After long-continued repetitive motion in which small groups of muscles are used excessively, the muscles involved may not function when called upon to perform Uie accustomed task, although their func tion is unimpaired tor other activities. This condition, of which a typical example is writers* cramp, is referred to as occupational or professional neurosis. Whera continuous pressure or shock is the cause, pads or cushions are often beneficial. Workers who have to grasp tools tightly would do well frequently to change their method of holding the instrument, if this is possible. Occasional rest periods will do much toward the prevention of muscular pains ami cramps. # 30 OCCUPATION HASARDS AND DIAGNOSTIC SIGNS SYMPTOM, CONDITION, OS WUU VO LOOK POR Pala of muscle Med, set ap bp a myoaltls, borat(Is, synovitis, or other local cbangoaof a ebnmle InKoammlory aatura; trembling, cramp.

Poisons Industry today produces or employs s far greater number of poi sonous compounds than ever before. Extensive chemical research, particularly in ths field of the volatile solvents, is adding to the number every year. The production of new synthetic materials find* ing industrial uses as substitutes for wood, textile, and other natural products, lias also added to the list It would be impracticable to cover all or even the greater number of these industrial poisons in a work of this kind. Only tlie more important ones concerning which we know something of the toxicity haye been included. Some poi sons, long used in industry, on the oilier hand, are being displaced. Since it is extremely difficult to determine whether their use hnsbeen ' entirely discontinued, and we cannot foretell when a new use will be found for them, their inclusion In our list lias been thought desirable. The revised List of Industrial Poisons, compiled by Sommerfeld and Fischer for the International Association of Labor Legislation1 formed the basis for the data presented in the section on poisons in the first edition of this bulletin. The material in that list has been revised and amplified in subsequent editions, and new poisonB have been added. Tne Bymptonra cited are those which are reported in the best Works available. In order to avoid swelling the list of 'tisons to unwarranted proportions, substances whose effects are nilar have been grouped. Thus alt nitro compounds of benzol ^nd Its homologues liave been included under one heading, and the same procedure nas been followed with amino compounds. The next section is devoted to the substances occurring in industry which pro duce typical occupational dermatoses. Because of the very large >ImD. i Ns. too. Washington, ISIS. LUrr u jiazauub, bvxreiund, etc. di number of substances In the latter class, it lisa not been possible to treat them es fully as the other poisons. The occupations and industries listed under the various poisons ere those in which tin hasard may be present. They are not neces sarily those where actual cases of poisoning hare been re|mrted. Adequate preventive measures, vigilantly earned out, may make Ih chance of poisoning from even an extremely toxio compound vir- tually impossible. That fact has been fully established by the splendid record of many American companies which have manu factured some of the most toxic compounds for years without having single case of poisoning develop In their plants. To prevent, industrial poisoning the following precautions should betaken: Workers must be instructed as to the toxicity of the substance bandied. Frequent medical examinations of workers must be mad to detect early symptoms of disease. Before new substances are employed in industrial processes, their toxicity should be determined. Persona! cleanliness must be maintained, and proper washroom facilities, therefore, should be provided. Men sliould not be allowed to eat in workrooms where jwisoiious substances are handled. Work clothes should receive special attention and should be removed at the end of tho duy's work. The use of gloves and boots is often necessary. Mechanical devices for confining the poiaons are of prime impor tance. Reference sliould be made in this connection to (lie preventive measures discussed under "Dust.1* Fumes and gases should be taken care of by proper ventilation, the use of exhaust systems, faro. and blowers. * If, complete removal of the poison ia not possible, men who are required to work in an atmosplicre polluted by poisonous fumes and gases should wear respiraturv protective devices constructed for tlie ywdfto poison with which they work, and approved by the United States Bureau of-Mines for tlie conditions of exposure likely to be encountered.

Methyl Formate Methyl formate la used In fumigants. It baa also been considered for use aa a high boiling refrigerant tor housebold appliances. The United States Bureau of Mines studied the acuta responses of guinea pigs to a alnght expoaare lo vapors of methyl formate. According to this Bureau, tha animals showed, In their order of occurrence, nose and eye Irritation, reteblug movement, nucoordlnation, narcosis uccomiaiulcd by uncoordinated movements iff the extremities, and death. Methyl formate vapor was found to be Irritating to the lungs. Congestion and edema were the moot constant and prominent findings after exposure which resulted lu death. A hyperemia of the liver and kidneys and congestion of the sartoep vessels of tbe brain and adrenals usually accotapuulcd tbe lung changes. Lung Irritation was frequently found immediately after exposure which dhTnot cause death, but was absent In animals examined 4 to 10 days following exposure. Men exposed for 1 mlmile to 0.1B percent vapor In air, according lo the same authority, noticed Die idenaant ethereal odor or methyl formate, but cs|>ertencvd no nusal or eye Irritation or other signs or symptoms While the odor of methyl formate Is distinct and oollccubls In concentrations which am relatively sato from the slundpolnl of producing neule poisoning. owing to Its pleamint tutlure mid Ilia nccurrcncs of olfactory totlgue It la doubtful whether tbo odor of methyl formate will servs as an effective warning of harmful conditions of s'-'-nire.

Because the dermatoses form so Urge a proportion of all disabling occupational diseases the more Important occupations exposed to agencies producing skin affections have been listed separately. A complete enumeration of such occupations would be impracticable. Almost any foreign substance can become a Bkin irritant if it is in continuous contact with tlie akin. Tlius soap and water, which ordinarily do not irritate the akin, may causa severe dermatitis in laundresses. Under the dermatoses are included the effects on the Bkin of such causative agencies as poisonous end Irritating chemicals, heat end cold, dust, radiant energy, friction, plants and wood, proteins, and vegetable and animal parasites. Occupational dermatoses are frequently distinguished by their grouping, situation, mode of appearance, spread, ana evolution. They are most often local and predominate on the right side of riglit-handea people. Hie onset and development are usually sudden. Tlie associa- r O other substances, however, have no specific lesions or special pathology, and some are selective in tlie people in whom they cause injury, thus making it more difficult to associate Hie condition with occupational exposure. Hie excellent work by Drs. Louis Schwarts and Louis Tnlipan, entitled "Occupational Diseases of the Skin,1* fully treats of Hie dis eases of tlie skin and the agencies involved in their causation. It should he consulted by anyone who has a need for an extensive work on the subject. Dr. It. ProsserWhite's book enUtledThe Dennatergoses: or Occupational Affections of Hie Skin" is another very fine work. Tlie data presented in this section are based largely on these two volumes. Tlie following is a list of the more common occupations exposed to agencies causing dermatoses. It is a partial list only. Reference sliould aim be made t Hie specific hazards listed for the occupation under consideration in section I.
