The symptoms, conditions, r diseases cited are those which are reported tn the but 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 which have been reported as offering ex posure to inch hazards, and not necessarily those in which apecilio esses of injury have occurred. The form of the pamphlet haa been changed somewhat to facilitate reference to the symptoms and occupations listed under each hesard. While the number of hazard groups remains the seme, we have com pletely revised the method of presenting some of the hazards. M Ex treme light", now listed as w radiant energy ", has been subdivided to those of M extreme dry hest " and " sudden varistlons of tempera ture.1* The hazards covered now include " abnormalities of temper ature "compressed air"; "dampness": " defective illumination "dust"; "infections": "radiant energy"t "repeated motion, pres sure, ahock, etc"; ana the "poisons." The section on "skin irri tants " is now listed under the heading " dermatoses." The number of poisonous substances considered has been increased from 59 to 94. Hie number of hazardoua occupations listed has been increased to approximately 900. The authors desire to acknowledge their indebtedness to the mem bers of the medical profession ofthe United States and Canada, wh have so graciously received the previous editions, and who hava bo enthusiastically cooperated in extending its scope. It would be impracticable to make personal acknowledgment of all the assist ance which has been received In preparing this revision. Mention, however, should be made of the following authors and organizations from whose published works so large a part of the information used u. 111MIS As IT XJIIIIIIill A IIUill|IOVII} Mll| MOV WIV International Labor Office of the League of Nations, Harvard School of Publio Health, United States Bureau of Labor Statistics, United States Public Health Service, United States Bureau of Mines, and tlie Bureau f Industrial Hygiene of the New York State Depart ment of Labor.

Hie health of those who work with the poisons, such as lead, arsenic, mercury, picric acid, etc., of those who are exposed for long periods to dust, heat, humidity, r to the infectious materials, may be impaired seriously as the result.of their work. The occupation is now recognized as of the very first irn- ortance as a factor in the causation of disability and even f death. fa see titis reflected in the frequent revisions of compensation laws to Include an increasing number of occupational diseases. Dr. Edsall has shown that in the clinic he conducted at the Massachusetts General Hospital many of the conditions for which treatment was sought by men of worjeing ages were the effects of occupation. Other, industrial clinics are reporting similar results. With their attention directed to occupation as a possible factor, industrial physicians are able to diagnose a great many obscure cases which previously had puzzled even the most competent clinicians. In this way they discover .a great many more cases of disease f occupa tional origin than haa before been thought possible. Thus, In 1917, about 160 cases of lead poisoning ware discovered at the Massa chusetts General Hospital, which are more than were receded by this clinic during the 6-year period prior to the adoption of the more intuitive methdda of study. It is generally recognized that patients coma to physicians with pains and complaints of an in- definite character, and it la only when consideration is given to the occupation and its possible effects that many of these cases are cleared up. Hie medical examiner should therefore be very careful to aee 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 their patients, where no other explanation of the csss is readily available. In the case of those exposed to lead, such as employees of storage-battery plants, white-lead workers, paint mixers, painters, etc., the blue line on tha gum, the pale, sallow ap pearance, and the trembling fingers are significant as indications of chronic lead poisoning, and the physician should look for these signs. Physical symptoms and conditions which ordinarily might be passed by, in this way become very important if they point to the possible affect of the occupation. 2 OOOUPAIIOV HKWM AHD DIAOHOBTIO BUMS _. This handbook has been prepared to aid physicians in genera) praci. j tke, industrial hygienists, safety engineers, and others wno come into ' dose professional contact with those who are engaged in industrial O processes. Nine major hazards of employment are listed; namely, abnormalities of temperature**; "compressed air": "dampness"; firi defective illumination **;Ndust"; "infections " radiant energy **; repeated motion, pressure, or shock '*: and the " poisons." A sepay.. j rate section of the bulletin is devoted to a discussion of the der4 ; matoees. Long exposure to any of these will usually leave definite ?. * physical signs which the medical examiner can discover if he will 1 . look for them. To aid him in detecting the hsxsrds and their effects n the worker, two lists an presented. The first consists of the more ;' common hazardous occupations, arranged alphabetically; the aecond ' ' consists of hazards, together with their effects or symptoms, as well J as the occupations affected. After each occupation in the first list is a reference in code to the particular hazard in the second list.* The . capital letters after each occupation, A, B, 0, etc., refer to the general hazard. Hie arabio numerals signify the particular hazard!, as E 1, inorganic dust; E 9, organic dust. - The following example will show how this guide may be of value 'to the general practitioner: A man, who works in a garage, suffering from continuous headaches visits his physician. The latter can find no cause for the patient's illness. The patient shows no sign of disease other than the subjective symptoms which he describes. Per haps the physician will recommend an examination of the subject's eyes, ears, and sinuses, which will prove negative. A correct diag nosis in a puzzling case such as this is much easier to determine when the occupation is ascertained and this guide is utilized. Alongside of "garage workers** in the Alphabetical List of Hazardous Occupa tions, Hie physician finds the symbols J 15,24.01,85. "J ** represents the hazard " poisons", ud 10, 24, 51, 85, the particular poisons-- gasoline, carbon monoxide, lead,' and tetraethyl lead, respectively. Upon looking up the symptoms of these poisons in the second list, he Ands that all produce headache. In such i case an effort should be made to discover which of these poisons exists as a hazard in the plant where the' patient ia 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 Alpha betical List of Hazardous Occupations (p. 4). If found there, it is possible that the person has been exposed to and is possibly suf fering from the effects of some hazard of his occupation. The num erals will indicate the naiticular hazards of the occupation. The nhysician should then make special effort to discover the symptoms ir signs referred to in the second list. By this meins he can readily \ determine whether the person examined is in fact suffering from the effect of his occupation. His examination is in this way made more illuminating. Physicians, not specialists In occupational hygiene, can thus learn to detect toe effects of industry ana, conversely, can eliminate the occupation as the cause when certain symptoms are ob served whi'* 4 not fit the usually observed effects of the occupation. A 3 In JLl OJ *C-- o UJ CL. C3 c O c: V. s u o o Ui INTBODJIOTIOH 3 Medical examiners should remember that It la often necessary to keep in mind not only the nresent occupation but the former one as well. Persons suffering from certain ailments may no longer be engaged in the industry which was responsible for their condition. But careful inquiiy into their occupational history will sometimes result in the reconliiig of in occupation the effects of which are clearly those from which the patient is suffering. The medical {irofession must give occupational findings greater weight in form- ng their judgments regarding physical conditions and in diagnosing ana treating disease. 1 It is hoped in this wey that tha medical profession will become more and more acquainted with occupational diseases and help in tli^ movement to discover and eliminate cases thereof. In our country, it is still true that very large numbers of working people are con stantly exposed to serious occupational hazards and suffer, often unnecessarily, very seriously from the effects of such exposure. The greater interest of medical practitioners will help materially in the campaign of prevention. Medical schools esn aid greatly in bring ing about this result by giving due weight to the subject in their courses of study. Already the form and content of the pamphlet have recommended it to several schools, which report Its value. Ia the same way, plant executives and safety engineers must take cog nizance of the existence of these occupational diseases and look care fully into their own establishments to see to what degree the proc esses in their shops are devoid of the dangers which are usually associated with industrial Operations. Factory inspectors, labor officials, snd workmen's compensation boards will find it helpful in inspecting and evaluating the hazards of numerous industries. Many hazards may be revealed which they have not known were associated with the processes of manufacture and of which the employers themselves have been ignorant. The vapidly expanding field of industrial rehabilitation should find this bulletin an aid in selecting occupations for those with arrested of tuberculosis and for others weakened by disease.

Abnormalities of Temperature and Humidity Exposure to environmental temperature beyond the. action of the body's thermostatic control primarily results in disturbances of the circulatory system. The cutaneous circulation responds to heat stimulation in the skin by increasing the blood flow through the capillaries. The capillaries, responding to a reflex action of the nerves in the skin, dilate ana induce the flow of a greater volume of blood through the cutaneous circulation. Cold, on the other hand, constricts the blood vessels of the skin, causing a diminished blood* supply through the cutaneous circulation and not infrequently a serious congestion of tits internal organs. Abrupt changes of tem peratures, particularly from extreme heat to cooler leni)H!ratures and often to cold currents of air or drafts, are of more frequent occur rence, resulting in much bodily discomfort, and are contributory causes of neuralgia and respiratory diseases. Extremes of tempera ture may produce acute symptoms in the body directly attributable to the temperature. Thus, expupure to excessively high tempera tures results in heat exhaustion or heat stroke) to excessively low temperatures in frostbite or gangrene and death. The relative humidity is an important factor to consider in con nection with temperature. It is contended that a low relative humid ity tends to dry up the mucous membranes of the nose, throat, and lungs, thus lowering the resistance of these organs to infection. An excessively high relative humidity, on the oilier band, ia undesirable because of Us interference with the normal evaporation of moisture from the skin. Under extreme conditions of high temperatures and high relative humidities there occurs a msrked increase in tb pulse rate, systolic blood pressure, And in tlie body temperature. Low tem peratures and high relative humidities have the effect of undermin ing the general vitality of the organism, weakening its resistance to diseases of Ilie respiratory passages, aibd to neuralgia and rheumatie affections. With the above data in mind, abnormalities of tempera ture have been classified under three headings, namely, "sudden variations of temperature ", M extreme dry heat", and " heat and humidity." u Extreme cold " has not been fisted as a distinct hazard, because temperature so low as to cause the direct effects mentioned above is rarely met in industry. It is evident that the occupations listed in the divisions " extreme dry heat", and " heat and humid ity," are exposed not only to the danger of the direct action of the high temperatures but also to the hazard, "sudden variations of temperature." The prevention of diseases due to exposure to extremes of tempera ture consists, obviously, in the ftvoidsnee of sudden variations of IS CO n i t 14 OOOUPATKW HAZABD6 AND DUQNOSTIO BIQNB tornMixture. Worker* In cold processes should keep active end avoid chill. The hot-process worker should allow his body to cool off gradually after completion of the day's work. He should car fully regulate his diet, drinking plenty of water. As direct preventive measures for the effects of extreme heat, it is advisable to make use of shields, helmets, goggles, water-cooled furnace doors, exhaust systems, cold air, fans, etc. Our knowledge of the responses of the body to atmospheric con ditions has been greatly enhanced recently by studies of American and foreign investigators. Men undergoing exposure to varying degrees of temperature, humidity, and movement of air have been medically examined. It has been amply demonstrated that these variable factors must be jointly considered in determining whether working conditions are inimical to health. Zones of comfort and discomfort and f effective working conditions have been charted. Means to mitigate the hazards of nigh temperature and humidity in certain industries have been devised. Those who have need for technical data on these subjects will find much of value In the paper by Dr. R. R. Sevan and Sara Davenport, entitled M Review of Literature on the Physiological Effects of Abnormal Temperatures and Humidity ", in the United States Public Health Service Reports, April 8, 1927, page 988. and in reports of cooperative studies con ducted by the United States Public Health Service.

Pat tenderer* workera B. Compressed Air In building tunnels, laying deep foundations for large buildings, etc., it is necessary for tlie work to be carried on under increased sir pressure in order to prevent the entrance of water into the exca vations. The laborer is lowered gradually end, at short intervals, the pressure of the air in the compartment is increased. The first sensation of compression is felt on the eardrums, which msy be re lieved by tlie ect of swallowing. If the air is too auickly compressed hemorrhage may occur. The greater part of the danger of working in compressed sir lies in hasty decompression. While under com pression the blood end tissue juices dissolve an increased amount of air, the gases of which are released when the pressure is suddenly decreased. The bubbles of nitrogen thus formed cut off the blood supply from vsriouB parts of the body by blocking up the capillaries. The symptoms of compressed-air illness, the so-called w bends " are the result. Workers in compressed sir must follow strictly the rules covern- ing gradual compression and decompression. State regulations re garding work in cumpressed air cover limits of pressure, hours of labor under varying pressures, time of compression and of decom pression, physical reauirements, and oilier safety measures; see, for example, industrial Code: Rules Relating to Work in Compressed Air, Bulletin N . 23, of the New York State Department of Labor, 1022 Ht amendment lo theta rules reported in Special Bulletin No.. the New York State Department of Labor, 1825, page 24. list or hazaubb, symptoms, bto. 17 B.

There remains, however, to be considered, exposure to wet conditions where tem perature and humidity are apparently not abnormal. Such condi tions are brought together under the heading w dampness." Tank and vat men, washers and flushera, for example, are required to carry on their duties constantly in wet clothes. Drivers snd other out door workers are also subject to frequent wetting from exposure to the weather. Exposure to dampness generally has been considered to be a con tributing factor in diseases of the respiratory system, neuralgic end rheumatic affections. Possibly dampness, like sudden variations in termn perature, taxes the heat-regulating mechanism of the body. When dampness ia a feature of any industrial process, work places should be supplied with drain channels to prevent the accumulation of water, or uae should be made of duck boarding. Adequate water proof clothes should be supplied, such as rubber boots, rubberized aprons, etc. C.

Defective Illumination Defective Illumination, characterised by insufficient, quantity of O c/> - light, glare, unsuitability of color, and Improper diffusion and dis- $- tribution ox light,isthe cause of eye fatigue, headache, dixsiness, and c:i errora f refraction. Miners' nystagmus, a condition In which Uio eyeball acquires a1 peculiar oscillatory movement, is an outstanding uh example ox the effects of insufficient illumination. This disease Is very common among British miners, hut apparently la not found to any extent among American miners. The explanation for the favor able situation or the American miner probably lies in the better illumination of the American mines. Not only is defective illumina c tion the cause of these serious impairments of vision but it is an i- important factor in reduced working efficiency in industry generally, ana it is a very frequent cause of industrial accidents. i. The hazard of defective illumination ia not limited to any single industry or group of industries. It may be present in any plant. ..I Men engaged in occupations requiring close, fine work, bucIi as jewelers, engraven, clerks, snd mail sorters, are especially liable to suffer from exposure to this hazard. It ia a comparatively simple matter to provide for all the require ments for properly illuminating workplaces in some industries, while in othen the advice of illuminating engineers ia required. The American Standard Code of Lighting for Factories, Mills, snd Other Work Places^ prepared by the Illuminating Engineering Society of New York City, ia an excellent reference work for those who have need of a knowledge of the technical requirements of the work.

E. Dust 0l*ZZ Uf J Dusts have been divided into two kinds--organic and Inorganic. Organic dusta do not cause pulmonary lesions, while inorgsnio dusts produce fibrosis of the lung tissue, the extent of which depends upon the kind of dust, the sin of the dust particles, the concentration of dust, and the length of exposure to the particular .dust inhaled. Dr. H. B. M. Landis found that, when fibrosis was present in the lungs of men exposed to organic dust, the latter was always mixed with some form of inorganic duBL Workers exposed to organic dust for years showed no pulmonary changes other than those found in people living in the city. Dust, whether organic or inorganic, by acting as s carrier of bacilli, may increase their number in the lungs. In this way men exposed to dust may be in greater danger.of con tracting tuberculosis than others. Whether or not all inorganic duBta, per se, are capable q ing lung fibrosis, given a sufficient length of exposure an enough concentration of dust, is still an open question. H c(h r- ganic dusts found in industry have been inhaled for lof ids without noticeable injury. Dusts containing free silica, ho I ire definitely known to he extremely harmful, producing serious pul monary damage in a comparatively short time. The pathological condition resulting-from exposure to Bilica dust is properly referred to h silicosis. X-ray pictures of the silicotic lung show a character istic mottling due to the formation of fibrotic nodules where silica has lodged in the lymphatic system. Symptoms of the disease may not show until it is well advaheed, when there is a decreased lung expan sion, marked shortness of breath, and cough. The silicotic lung is a fertile field for the tubercle bacillus: a very largepercentage of:ases of silicosis terminate in a fatal tuberculosis. The action f silica on the lungs is to promote the growth of connective tissue. Asbestos dust ia another dust which, it has recently been definitely determined, produces a lung fibrosis under existing industrial condi tions, although its action is apparently milder than that of free silica. The relation of tuberculosis and asbestos dust is not entirely clear. Complete protection for workmen exposed to silica dust has been found difficult in many processes. X-ray pictures, therefore, should be taken at regular Intervals of all workmen exposed. It u of the utmost importance that these pictures be interpreted by a physician familiar with Uw> appearance of the lungs at various stages in the development of silicosis. Workmen who are found to be affected should be transferred to other jobs, where they will not be exposed to dust. There are four methods that may be used to keep down the amount of dust generated through industrial processes. No one of these can apply to all conditions, but the particular method to be used must be adapted to the peculiarities of the process. 1. The ubo of water dr oil to wet the dust, thus preventing it from rising and filling the atmosphere. Thia method Is now believed to be of doubtful value in aomo processes, and in these should not be retied upon when other methods are practicable. S. The use of exhaust systems which remove the dust at the point of origin. 1IU1S*- 4 t 20 OCCUPATION nUUIDS (Nil ItUdnMito a*u.w 8.

Among the more common of these are anthrax, hookworm, tetanus, trachoma, {^antlers, tularemia, actinomycosis, ringworm, athlete's foot, undu- ant fever, and septic infections. Anthrax, hookworm, anti septic infections are of esj>ecisl intemt because of the frequency of flicir occurrence in industry. A brief summary, therefore, of tits symp toms of these diseases and the principal occupations in which infection is likely to occur have been included. Prevention of these diseases lies in the observance of th wellestablished rules of general ssnitation. The following special meas ures are also recommended: uw 11U IJUUtHMiiU UIU4)J 1. Anthrax.--All hidea and animal hair must bo thorough!/ steri lized. Foreign akins or hair ahould not be carried on the unprotected shoulder. The hands should be frequently washed with bichloride of mercury. Hair sorters should wear respirators. 2. Hookworm.--Workers in mines and others who are exposed to Infected soil should make special effort to keep the skin clean. Shoes _must always be worn and gloves are also of value in preventing the entrance of the hookworm through the skin. Infected soil should be disinfected and kept dry. The utmost attention should be given to the prevention of soil pollution. S. Septic infeoticne.--Cuts, scratches, or abrasions should be treated, at once to avoid Infection.

(rribtMaak Tho increasing use of X-rays and of radium in tha detaction and treatment of disease and the more extended use f X-rays In indus try sb an aid in detecting hidden defects in metals hare greatly added to their importance as potential sources of occupational dis- ; ease. Recently, radioactive substances (radium, radiothorium, mesothorium) have been added to the list of occupational hazards found in manufacturing industries following upon the discovery that these substances were responsible for the serious Impairment I and death of several young women who had been employed in the painting of luminous watch dials with radioactive paint. The nsztrd u now known to be present also in several other industries. Exposure to X-rays and emanations from radium and other.radio active substances may produce serious burns and cancer, while the blood and blood-forming organs are profoundly affected. Anemia and leukopenia are frequently associated with exposure to radiations; Much has been learned concerning adequate measures for the pro tection of workers exposed to X-rays and radioactive substances since the esrly days of their discovery, when many pioneers in medi cal treatment with these new agencies, suffered severe mutilating disabilities because of their unmitigated exposure. Protective meas- 1 unis today have been worked (Hit in considerable detail for the variety of conditions met with. See for example, The Journal of the American Medical Association, April 27,1929, pages 1429-1430, and the Monthly Labor Review for June 1929, pages 22-24.

Then is little definite evidence that welding may causa cataract, similar to glassblower's cataract, but it is prob able that prolonged exposun to infrared nya may cause haziness f the cornea (part of eyeball).

This section is not concerned with the neurasthenic phenomena fol lowing accidental injuries, commonly referred to as traumatic neu rosis. Everyone is familiar with the muscular strain experienced in performing for the first time some exercise, such as rowing, long walking, etc. Men newly introduced into a process requiring such repeated action are affected similarly but often much more severely, so as to disable them temporarily for the particular job. After*-* long-continued exposure the muscles involved do not function when called upon to perform the accustomed task, although their function is unimpaired for other activities. The injury does not stop with muscular strain but may even cause inflammation of the surrounding shentlis or paralysis of the parts concerned. Where 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 or holding the instrument, if this is possible. Occasional rest periods will do much toward the prevention of muscular pains and cramps. H.

Poboni The continued introduction of new processes making use f new ri . poisonous substances and the increasing use in industry of other J well known to be injurious to health make this section of ' more and more importance. During comparatively recent years the -3 - , highly poisonous chemicals, tetraethyl lead and radio-active paints, vi have been introduced into manufacturing processes and have been j, '< productive of serious poisoning. A group of refrigerants (methyl V bromide, methyl chloride, ate.) have found widespread use in the manufacture of refrigerators and have proved Injurious to the health of workmen. Phosphorus, tetrachlorethane, and certain other chemi cals, on the other hand, have decreased in importance. Industrial - poisoning caused by these substances is comparatively rare today. Since we cannot foretell, however, when a new use wiO be found in industry for a poisonous substance, the inclusion of theaa chemicals In our list has been thought desirable. The revised List of Industrial Poisons, compiled by Sommerfetd and Fischer for the International Association for Labor Legislation, has formed the basis for the data presented In this section.1 The materiel in that list baa been revised end brought up to date. A number of poisons beve been added, end the occupations exposed an given for each poison. The symptoms cited an those which an reported in the best works available. In order to avoid swelling the list of poisons to unwarranted proportions, substances, the effects of which an similar, have been grouped. Thus ell nitro compounds of benzol and its homolomiea have been included under one heading, and the'aame procedure lias been followed with amino compounds. The next section (p. 50) is devoted to the substances occurring in industry which produce typical occupational dermatoses. Because of the very large number of substances in the latter class it has not been possible to tnat them as fully aa the other poisons. To pnvent industrial poisoning the following precautions should be taken: Workers must be instructed as to the toxicity of the substance bandied. Frequent medical examinations of workers must be made to detect early symptoms of disease. Before new substances are employed in industrial processes their toxicity should be determined. Personal cleanliness must be maintained, and proper washroom facilities, therefore, should be provided. Men should not bo allowed to eat in workrooms where poisonous substances are handled. Work clothes should receive special attention and should be removed at the end of the day's work. The use of gloves end boots is often necessary. Mechanical devices for confining the poisons are of prime Impor tance. Reference should be made in thia connection to the preventive measures discussed under H Dust." Fumes and gases should be taken care of by proper ventilation, the use of exhaust systems, fans, ami. V blowers. Men who work in an atmosphere polluted by poisonous fumes and gasea should always wear gaa masks properly suited for the obtaining conditions. 1 Bee O.B. Soma *t labor Statistic* Sul. Ha. 100.

Because the dermatoses form so * !. large proportion of ell disabling occupational diseases, the more Important occupations exposed to agencies producing skin affec tions bare been listed separately. A complete enumeration of such occupations would be impracticable. Almost any foreign substance can become e akin irritant if it ia In continuous contact with the skin. Thus, soap end water, which ordintrilj do not irritate the skin, may cause serere dermatitis in laundresses. Under the derma toses are included the effects on the skin of such causetire agencies as poisonous and irritating chemicals, heat and cold, dust, radiant energy, friction, plants and woods, proteins, and vegetable and animal parasites. Occupational dermatoses are frequently distinguished by their grouping, situation, mode of appearance, spread, and evolution. They crop up in series, retaining their initial type throughout, un less they ere secondarily infected. They ere most often local, except when they are a differentiating sign of the toxemias. The onset and development are usually sudden. The inflammation is sharply utllned. Exudation ia excessive, end there is a deep-seated edema. Tiie eruption usually predominates on tha right side. Skirt affec tions caused by different external irritants often, however, may uliow tiie same clinical picture. A number of occupational skin eruptions have no specific lesions or special pathology, which makes their differential diagnosis very difficult. For these reasons, the symptoms for each irritating substance have not been listed as has men dona for the other hazards. The excellent work of Dr. It. Prosser White entitled ** The Derina- tergoses, or Occupational Affections of tike Skin tt, admirably covers tiie entire subject of causative agencies and differential diagnosis.

The following is e list of the more common occupations exposed to agencies causing dermatoees. It ia a partial list only.
