Co. in the discovery of impairments among applicants for insurance. The pamphlet soon attracted the attention or others not immediately interested in insurance medical examinations. Industrial physicians, directors of compensation boards, factory inspectors, safety eturineers, industrial rehabilitation agents, faculties of medical colleges, and. most important of all. general practitioners of medicine, have made a call for this work and have expressed their approval of it. Sub sequent editions have been equally well received. It has been repro duced either in whole or in part in a number of works by authorities on the subject of industrial hygiene. The present publication is a complete revision of Bulletin 2?o. 582 of the United States Bureau of Labor Statistics, issued in 1933 under the same title. The authors are convinced by their experience with these earlier editions that this bulletin has served a useful purpose, and that there is a vital need for a compilation, of this kind, which makes readily available the most recent findings on industrial hazards to those who have not the time for a thorough study. Obviously, the extension of the compensation laws of the severalStates to include all occupa tional diseases, or an increasing number 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 hazards will find detailed information in the sources referred to in the last section. The two decades which have passed since the first edition of this bulletin was prepared have been years of tremendous expansion in the field of industrial hygiene. It has come to be recognized as an important branch of industrial management in which industrialists, < physicians, engineers, chemists, laboratory technicians, statisticians, labor law administrators, workmens 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, They have been years noteworthy for the large number of scientific investigations undertaken here 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 specific industrial exposure;:. Our idea that dusts, for example, were injurious in proportion to the hardness and sharpness of their particles, has been shown to be erroneous. It is now neld that dusts are injurious in proportion to the amount of free silica or the amount of asbestos they contain Our knowledge of the effects of many other hazards, long recognized as injurious, has been enhanced, and in addition a wealth of in forma - VI PREFACE tion has been supplied on the effects of important new hazards, notably the volatile solvents and chemicals employed in the manu facture of synthetic resins, to mention onlv twqt In preparing- this, the fourth edition of the pamphlet, the authors have endeavoreu ro present the most recent thought on occupational hazards expressed in this vast literature on industrial hygiene. They realize full well the inadequacy of existing knowledge of the effects of many industrial hazards, and the amount of scientific research necessary before these effects are definitely known. They have not presumed to attempt to settle controversial questions, nor have they attempted to set up standards for the guidance of those whose responsibility it is to puss upon claims for compensation or damages. The symptoms, conditions, or diseases cited are those which "ire reported m 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 which the hazard may be present, and not necessarily those in which specific cases of injury have occurred. It should 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, are manufacturing or handling extremely 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 ana employees worked together toward that end and this may be said of many other hazards. A word of caution should be given to the layman against the use of the material presented here for self-diagnosis or for diagnosing the illness of others. That is a practice fraught with the gravest 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 health. The hazards covered now include `abnormalities of air pressure;" "abnormalities of temperature;'' "dampness;" "defective illumination;" "dust;" "infections;' "radiant energy;" "repeated motion, pressure, shock, etc.;" the "poisons:'' and "dermatoses. The number of poisonous substances considered has been increased from 94 to 128. The number of occupations listed has been increased to approximately 1.100. The authors desire to acknowledge their indebtedness .to the mem bers of the medical profession of the United States and Canada who have so graciously received the previous editions and who have so enthusiastically cooperated in extending its scope. It would be im practicable to make personal acknowledgment of all the assistance which has been received in preparing this revision. Mention, how ever, should be made of the following authors and organizations from whose published works so large a part of the information used in the pamphlet was secured: Drs. Alice Hamilton, George M. Kober, Emery H. Hayhurst, Yandell Henderson, Howard W. Haggard. R. R. Savers, W. F. Von Oettingen, L. Schwartz, L. Tulipan. W7D. McNally. H. F. Smyth, R. Prosser White, Carey P. McCord. Henry H. Kessler, Ethel Browning; and also the International Labor Office of the League of Nations, Harvard School of Public Health, United States Department FRETACE vi r of Labor, United States Public Health Service, United States Bureau of Mines, and the Division of Industrial Hygiene of the New York State Department of Labor, / The authors are especially indebted to Dr. Anthony J. Lanza and Dr. William J. McConnell, assistant medical directors, and to Miss Eleanor Rantoul. all of the Metropolitan Life Insurance C'o., for re viewing the entire manuscript, for assistance in the preparation of the text, and for manv valuable criticisms suggested By their broad ex perience in the field of industrial medicine.

The health of those who work with the poisons, such as lead, arsenic, mercury, picric acid, and so forth, or those who are exposed for long periods to dust, heat, humidity, or to the infectious materials, may be impaired seriously as the result of their work. The occupation is now recognized as of the very first importance as a factor in the causation of disability'and even of death. We see this reflected in the frequent revisions of compensa tion laws to include an increasing number of occupational diseases. It is now generally recognized that patients come to physicians with pains and complaints of an indefinite character, but which in many instances are tne effects of their occupation. With their attention directed to occupation as a possible factor, physicians are able to diagnose a great many obscure cases which previously had puzzled even the most competent clinicians. In this way they discover u great many more cases of disease of occupational origin than had before been thought possible. The medical examiner should therefore be very careful to see if any of the usual diagnostic signs of poisoning, dust, 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 case of those exposed to lead, such as paint mixers, painters, and so forth, the blue line on the gum, the pale, sallow appearance, and the trembling fingers, are significant as indi cations 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 effect of the occupation. This handbook has been prepared to aid physicians in general practice, industrial hygienists, safety engineers, and others who come into close professional contact with those who are engaged in indus trial processes. Nine major hazards of employment are listed: namely, "abnormalities of air pressure''; "abnormalities of tempera ture"; "dampness"; "defective illumination"; "dust"; "infections"; "radiant energy"; "repeated motion, pressure, or shock"; and the "poisons." A separate section of the bulletin is devoted to a dis cussion of the dermatoses. Long exposure to any of these may leave definite physical signs which tne medical examiner can discover if he will look for them. To aid him in detecting the hazards a in I 1 o OCCUPATION HAZARDS AND DIAGNOSTIC SIGN'S their effects on the worker. two lists are presented. The first con sists of the more common occupations in which hazard*. may be found, arranged alphabetically: the second consists of hazards, together with their effects or symptoms, as well 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. C. and so forth, refer to the general hazard. The arable numerals signify the particular hazard, as E 1. organic dust; E :2. inorganic dust containin'; free silica. The following example will show how this guide may be of value to the general practitioner: A man who works as a prefer, suffering from continuous headaches, visits his physician. The latter can find no cause for the patient's illness. The patient shows no signs of dis ease other than the subjective symptoms which he cle-rnbes. 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 pressers" in the Alphabetical List of Occupations, the physician finds the symbols H. J 27. UH" represents the hazard "repeated motion, pressure, shock"; "J" the hazard "poisons": and 27 the par ticular hazard "carbon monoxide." Upon looking up the symptoms of these hazards in the second list, he finds that carbon monoxide produces headache. In such a case an effort should be made to discover if this poison exists as a hazard in the plant where the patient is employed. The remedy consists in the removal of the etiological factor--the specific poison. Hie 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 his occupation. The numerals will indicate the particular hazards of the occupation. The physician should then make special effort to discover the symptoms or signs referred to in the 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 it is often necessary to keep in mind not only 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. But careful in quiry into their occupational history will sometimes result in the re cording of an occupation the effects of which are clearly those from which the patient is suffering. The medical profession must give occupational 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 and help in the move I>TRODCCTIOX 3 ment to discover and eliminate cases thereof. In our country it is still true that very large numbers of working people are constantly exposed to serious occupational hazards and 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. The greater interest of medical practitioners will help mate rially in the campaign of prevention. Medical schools can aid greatly in bringing about this result by giving due weight to the subject in their courses of study. Already the form and content of this pamphlet have recommended ft to several schools, which report its value. In the same wav. plant executives and safety engineers must take cognizance of the existence of these occupational diseases and look carefully into their own establishments to see to what degree the processes or 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 which they have not known were associated with the processes of manufacture, and of which the employers themselves have been ignorant. Those concerned with industrial rehabilitation should find this bulletin an aid in selecting occupations for those with .arrested cases of tuberculosis or other organic diseases. All of the foregoing comments receive a special emphasis at this time due to the general defense program. One result of the enor mously increased manufacture of munitions of all kinds is the use of many chemicals about which little or nothing is known, and many of which are entirely new. Furthermore, the lengthening of the hours of work and of the number of work days in tne week ar.d the 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. 1 / Section I.--Alphabetical List of Occupations Abraslres worker?.

Compressed Air (Increased Atmospheric Pressure) In building tunnels, laying deep foundations for large buildings, aiul so forth, it is often necessary for the work to be carried on under increased air pressure in order to prevent the entrance of water into the excavations. After the workers enter the compression chamber or "lock" the pressure of the air in the compartment is increased gradually and at short intervals. The first sensation of compression is felt on the 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 air lies in hasty decompression. While under compression the blood and tissue juices dissolve an increased amount of air, the gases of which are re leased when the pressure is suddenly decreased! The bubbles of ni trogen thus formed cut off the blood supplyfrom various parts of the body by blocking up the capillaries. The symptoms of com pressed-air illness, the so-called "bends," are the result. Workers in compressed air must follow strictly the rules governing gradual compression and decompression. State regulations regard ing work in compressed air cover limits of pressure, hours of labor under varying pressures, time of compression and of decompression. fhysical requirements, and other safety measures; see. for example, ndustrial Code: Rules Relating to Work in Compressed Air, Bulle tin No. 22, of the New York State Department of Labor, 1922. and the amendment to these rules reported in Special Bulletin No. 135 of the New York State Department of Labor, 1925, page 24.

OCCUPATIONS WHICH OFFER SUCH EXPOSURE Caisson workers Divers Tunnel workers 2. Altitude; Rarefied Air (Decreased Atmospheric Pressure) In contrast to working under compressed air. rising to an altitude of 10.000 feet.as in aviation is accompanied by a reduction in the barometric pressure from 760 mm. at sea level, to 520 mm., and at 18,000 feet, the normal pressure is approximately halved. Exposure to decreased atmospheric pressure nas a profound effect on health. 534374* 15 16 OCCUPATION' HAZARDS AND DIAGNOSTIC SIGNS The physiological changes which occur are chiefly due to oxygen want (anoxia), and the term used for the resulting condition is "altitude siclmess." It may be acute, due to rapid asairit 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 the body decreases, the internal pressure mu>t decrease correspondingly if the body is not to burst; so, given, sufficiently extreme conditions of decreased pressure und rapia ascent, the internal gases of the body will expand and eventually, at altitudes of 30,000 feet or oyer, dissolved air bubbles will form in the biood vessels and tissues as in compressed air illness ("the bends"). "Aeroembolism" is the term given to this 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 eustachian tube prohibiting its opening may cause the drum to rupture. The lowered partial pressure of oxygen in the inhaled air at high altitudes has also a dangerous indirect effect in that it renders the individual more susceptible to carbon-monoxide gas should this be present in the pilot or passenger compartment. Low concentrations which would be considered safe at normal atmospheric pressure are capable of causing anoxemia and asphyxia at high altitudes due to the progressively decreasing oxygen saturation of the blood under these conditions. The discussion in this section is based upon the exhaustive treatment of the subject given in the work by Capt. Harry G. Armstrong entitled "Principles and Practice of Aviation Medicine," Williams & Wilkins, 1939. Anyone interested in any phase of this increasingly important subject will find this work indispensable. STKPTOM, CONDITION. OR DISEASE TO LOOK FOR Acute altitude eicknet (anoxia).--Sleepiness, headache, altered respiration, fatigue, psychological Impairments, unconsciousness, and respiratory failure. Warning symptoms preceding unconsciousness are not always present. There may be even a feeling of freedom from care because of the dulling effect on the sensory nervous system. The effects of snoxla after a flight may be more severe than the subjective symptoms noticed while flying. There may be persistent fatigue, severe head ache, nausea, vomiting, dizziness, abnormal behavior, mental confusion, and muscular weakness. Chronic altitude sicxnett.--Repeated exposure to anoxia (even without symp toms of acute altitude sickness) results in bodily and mental fatigue, lrritabilitv, insomnia, marked deterioration In efficiency, and disregard for danger in the air. Aeroembolltm.--The symptoms depend on the location and volume of the air bubbles, and may manifest themselves as joint palna. Itching, formicatlou. pul monary pain and edema, neuritis, paralysis, convulsions, and coma. Middle-ear dUturbancet.

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 stimu lation 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 and induce the flow of a greater volume of blood through the cutaneous circulation. Cold, on the other hand, constricts tne blood vessels of the skin, causing a diminished blood supply through the cutaneous circulation and not infrequently a serious congestion of the internal organs. Abrupt changes of temperatures, from extreme heat to cooler temperatures or vice versa, are of frequent occurrence, and are a contributory cause of respiratory diseases. Extremes of tem perature may produce acute symptoms in the body directly attributable to the temperature. Thus, exposure to excessively high temperatures results in neat exhaustion, heat stroke, or in heat cramps; to exces sively low temperatures in frostbite or gangrene and death. The relative humidity is an important factor 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, on the other hand, is undesirable because of its interference with the normal evaporation of moisture from the skin. Under extreme conditions of high temperatures and high relative hu midities there occurs a marked increase in the pulse rate, systolic blood pressure, and in the body temperature. Low temperatures and high relative humidities have the effect of undermining the general vitality of the organism, weakening its resistance to diseases of the respiratory passages, and to neuralgia and rheumatic affections. With the above data in mind, abnormalities of temperature have been classified under two headings, namely, ``Sudden variations of temperature," and "Heat." "Extreme cold" has not been listed as a distinct hazard, because the 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 also to the hazard, "Sudden variations of tem perature.'* The prevention of diseases due to exposure to extremes of tempera ture consists in the avoidance or mitigation 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 atmospheric conditions are becoming more and more com mon. Protective clothing and insulating methods can mitigate haz ards of abnormal temperatures. The use of salt as a preventive of heat cramps has. become a standardized procedure. Those who have a need for technical data on these subjects will find much of value in the chapter on "Lighting and Atmospheric Control" by Dr. William J. McConnell, in Industrial Hygiene, Lanza and Goldberg, Oxford Medi cal Publications, 1939; in the article bv C. P. Y&glou entitled "Ab normal Air Conditions in Industry; Their Effects on Workers and Methods of Control," in the Journal of Industrial Hygiene, January 18 OCCUPATION' HAZARDS AND DIAGNOSTIC SIGNS 1937, page 12. and in reports of cooperative studies conducted by the United States Public Health.

Dampness Aside from high atmospheric humidities wjfich have been dealt with under "Abnormalities of temperature-' there remains to be considered exposure to constant wetting. Tankmen, vatmen, and washers, for example, may be required to carry on their duties constantly in wet clothes. Such exposures are brought together under the heading "Dampness." Rheumatic and neuralgic affections may result from exposure to dampness, which also may be a contributing factor to respiratory infections. When dampness is a feature of any industrial process, work places should be supplied with drain channels to prevent the accumulation of water, or use should be made of duck boarding. Adequate waterproof clothes, such as rubber boots, rubberized aprons, and so forth, should be supplied. SYMPTOM. CONDITION. OR DISEASE TO LOOK FOR Respiratory, neuralgic, and rheumatic affections.

Defective Illumination Defective illumination, characterized by insufficient quantity of light, glare (light out of place), unsuitability of color, and improper diffusion and distribution of light, is the cause of eye fatigue, head ache, dizziness, and errors of refraction. Miners' nystagmu-. a con dition in which the eyeball acquires a peculiar involuntary oscillatory movement, is attributed to the effects of insufficient illumination. This disease is very common among British miners, but apparently is not found to any extent among American miners. The explanation for the favorable situation of the American miner probably lies in the better illumination of the American mines. Mot only is defective illumina tion the cause of these serious impairments of vision but it is an im portant factor in reduced working efficiency in industry generally, and it is a very frequent cause of industrial accidents. The hazard of defective illumination is not limited to any single industry or group of industries. It may be present in any plant. Men engagea in occupations requiring close, fine work, such as jewelers, en gravers, clerks, and mail sorters, are especially likely to suffer from exposure to this hazard. It is a comparatively simple matter to provide for all the require ments for properly illuminating workplaces in some industries, while in others the advice of illuminating engineers is required. The Ameri can Standard Code of Lighting for Factories, Mills, and Other Work Places, prepared by the Illuminating Engineering Society. New York City, is an excellent reference work for those who have need of technical knowledge on this subject. SYMPTOM, CONDITION.

Dust Dust arising from industrial processes is produced by mechanical action, such as grinding, crushing, cutting, drilling, and so forth. Its composition is similar to the substance or substances from which it is derived, and in this respect it differs from fume, which is the result of chemical action and which does differ from the substance of its origin. The size of dust particles is important because this influences their ability to be inhaled into the finer air passages and reach the pulmonary parenchyma.  22 OCCUPATION HAZARDS AND DIAGNOSTIC SIGNS Poisonous dusts are not considered in this section but under their appropriate headings relating to their composition. For practical purposes industrial dusts are divided into two classes, organic and inorganic. ORGANIC DUST Organic dusts contain carbon and are largely derived from 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 dermatitis or may irritate 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, satinwood. teak, some mahoganies, cocobolo, California redwood. Organic dusts 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 the body are ab sorbed. Coal is an organic dust, but on account of its origin is some times classed with the mineral dusts. Coal 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 a silicosis, modified by the presence of coal dust along with the silica, and is properly termed anthraco-silicosis. INORGANIC DUST Inorganic industrial dusts are mostly metallic and mineral. Of all the various types of such dusts, only those containing "free" or un com bined silica will produce the specific pneumoconiosis known as silicosis. Other inorganic dusts may cause some pulmonary fibrosis of a benign or nondisabling character. The action of silica dust upon the lungs 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 severe cases of silicosis frequently die with tuberculosis. Dusts containing silica in combined form, do not cause silicosis. However, one such dust, asbestos, a magnesium silicate, will produce a characteristic fibrosis. This is quite 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 be 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, other 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. Engineering methods for the control of dust comprise: LIST OF HAZARDS, SYMPTOMS, ETC. 23 (1) The ose of exhaust systems or suction devices which entrap the dust at its point of origin. / (2) The use of water, and occasionally mi. to lay the/dust and keep it out >>f the atmosphere.

Radiant Energy L X-rays, Radium, and Other Radioactive Substances (radiothorium, mesothorium, etc.) The increasing use of X-rays and of radium in the detection and treatment of disease and the more extended use of X-rays in industry as an aid in detecting hidden defects in metals have greatly added to their importance as potential sources of occupational disease. Radio active substances (radium, radiothorium, mesothorium) have been added to the list of occupational hazards found in various manufac turing industries. The hazard is now known to be present a!<o m several other industries. 28 OCCUPATION" HAZARDS .AND DIAGNOSTIC SIGNS 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 lias been learned concerning adequate measures for the pro tection of workers exposed to X-ray- ami radioactive substances since the early days of their discovery, when many pioneers 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. See, for example, United States Department of Com merce, National Bureau of Standards Handbook H'23. "Radium Pro tection and Recommendations of The British X-ray and Radium Pro tection Committee," fifth revised edition (January 1938). SYMPTOM, CONDITION.

Ultraviolet and Infrared Rays Ultraviolet and infrared rays are an industrial hazard in a number of occupations where there is exposure to excessive radiance. Welders and cutters especially are exposed to ultraviolet rays; furnacenien and other workers around molten metal and glass, to infrared rays. Al though we cannot see ultraviolet and infrared rays, they are 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 bums 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 cause permanent damage. Infrared rays act upon the eyes simply os heat, but may cause per manent damage (cataract). There is little definite evidence that weld ing has caused cataract, similar to glassblower's cataract, but it is probable that prolonged exposure to infrared rays may cause haziness of the cornea. The injurious effects resulting from excessive light due to defective illumination are not consideredliere, but treated as a separate hazard. See Hazard D. LIST OF HAZARDS SYMPTOMS, ETC.. 29 Goggles, helmets, shields, and masks, equipped with colored lenses especially designed to exclude the kinds and intensities of rays met with, afford protection to the eye. Booths should be provided tor welders working indoors to protect others working nearby. Ciothitui which covers the body completely protects the skin from irritation caused by the rays.

Repeated Motion, Pressure, Shock, etc. Under this heading are included those conditions which are caused by continuous repetition of movements, pressure, or blows peculiar to many occupations. This section is not concerned with the neurasthenic phenomena following accidental injuries, commonly referred to as traumatic neurosis. Everyone is 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 sucn repeated action are affected similarly but often much more severely, so as to disable them temporarily for the particular job. When the body is subjected to constant pressure or repeated 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 repeated shocks or vibration, there may occur also marked vasomotor changes with a characteristic condition known as "dead fingers.'1 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 the 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. 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 of holding the instrument, if this is possible. Occasional rest periods will do much toward i Inprevention of muscular pains and cramps. 30 OCCUPATION' HAZARDS AN'D DLAGN'OSTIC SIGN'S SYMPTOM, CONDITION.

Poisons Industry today produces or employs a far greater number of poi sonous compounds than ever before* Extensive chemical research, particularly in the 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, has 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 the more important ones concerning which we know something of the toxicity have been included. Some poi sons, long used in industry, on the other hand, are being displaced. Since it is extremely difficult to determine whether their use has been entirely discontinued, and we cannot foretell when a new use will be found for them, their inclusion in our list has been thought desirable. The revised List of Industrial Poisons, compiled by Sommerfeld and Fischer for the International Association of Labor Legislation 1 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 poisons have been added. The symptoms cited are those which are reported in the beet works available. In order to avoid swelling the list of poisons to unwarranted proportions, substances whose effects are similar have been grouped. Thus all nitro compounds of benzol and its homologues nave 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 larire 1 S D. a Bnreaa of Labor Statistic* BulL No. 100. Washington, 1912. LIST OF HAZARDS, SYMPTOMS, ETC. 31 number of substances in the latter class, it has not been possible to treat them as fully as the other poisons. The occupations ami industries listed under/the various poisons are those in wh:"h the hazard may be present. They are not nece-sarily those where actual cases of poisoning have been reported. Adequate preventive measures, vigilantly carried out. may make the chance of poisoning from even an extremely toxic compound vir tually impossible. That fact has been fully established by the splendid record of many American companies which have manu factured >ome of the most toxic compounds for years without having a single case of poisoning develop in their plants. To"prevent industrial poisoning the following precautions should be taken: Workers must be instructed as to the toxicity of the substance handled. 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, aiul proper washroom facilities, therefore, should be provided. Men should uot be 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 and boots is often necessary. Mechanical* devices for confining the poisons are of prime impor tance. Reference should be made in this connection to tne preventive measures discussed under "Dust." Fumes and gases should be taken care of bv proper ventilation, the use of exhaust systems, fans, and blowers. If complete removal of the poison is not possible, men who are required to work in an atmosphere polluted by poisonous fumes and gases should wear respiratory protective devices constructed for the specific poison with which they work, and approved by the United States Bureuu of Mines for the conditions of exposure likely to be encountered. 1.

Cellosolve (mono-ethyl ether of ethylene glycol) This compound is used as a solvent for nitrocellulose and resins in the manu facture of lacquers. The United States Bureau of Mines studied the acute response of guinea pigs to a single exposure to vapors of eellosolve. According to this Bureau, the animals showed inactivity, weakness, dyspnea, and death following exposure for 18 to 24 hours to air saturated with cellosolve vapor (0.6 percent by volume). The principal gross pathological findings were congestion and edema of the lungs; distention of the stomach, with numerous reddish-brown petecbiae scattered over the mucous membrane: and congestion of the kidney. The contents of the stomach were also discolored reddish brown. Ail these occurred in the animals that died during or soon after exposure. The congestion and edema were the principal rJ findings in the animals that died 24 hours following exposure and broncho pneumonia In the animals that died 3 days following.'......... They also determined that men exposed to 0.6 percent for a few seconds reported the atmosphere to be irritating to the eyes and to have a very disagreeable odor. They thought that the odor and the irritation were sufficiently disagreeable to f make one desire to avoid a like exposure. Actual examinations of workers in lacquer and paint manufacture by the British Factory Department in 1984 revealed very little evidence of any Injury to health from the use of cellosolve. 30.

It Is reported to be a good solvent for nitro cellulose and has possibilities of use in malting lacquers and also varnish and lacquer removers. The United States Bureau of Hines studied the acute response of guinea pigs to a single exposure to vapors of hexanone. According to this Bureau, hexanone produces in these animals narcosis, terminating in death in the higher concen trations. Symptoms are principally eye and nasal irritation, followed by nar cosis. Animals that did not die during exposure recovered. The principal gross pathological findings were congestion and hemorrhage of the lungs, slight congestion of the brain, and moderate congestion of the liver and kidneys, as observed in the autopsies performed immediately after exposure. Men exposed to 0.23. 0.6S, and 20 percent vapor in air, according to this same authority, pronounced the atmosphere extremely disagreeable even for a short time (one-fourth to 1 minute) bemuse of strong odor and irritation to eyes and nasal passages. One-tenth of 1 percent was found to have a strong odor and moderate eye and nasal irritation. Concentrations producing no marked symp toms and apparently harmless to guinea pigs after one exposure of several hours have distinct warning properties of both odor and irritation that are very disagreeable to human beings. 6L Hexone (Methyl Isobutyl Ketone) Methyl lsobutyl ketone, commercially known as hexone, bas been proposed as a diluent and denaturant of ethyl alcohol for external use, and is used indus trially in making varnishes and lacquers. The United States Public Health Service studied the acute response of guinea pigs to inhalation of methyl isobutyl ketone. They found that: "Methyl lsobutyl / ketone vapor Inhalation canses Irritation of conjunctival and nasal mucosa in man at concentrations below 0.1 volume percent, although this concentration is well tolerated by guinea pigs. This indicates good warning qualities. At higher concentrations marked irritation is exhibited by guinea pigs as evidenced by lacrtmatlon and salivation. A progressive narcosis occurs, causing lowering of body temperature, respiratory rate, and heart rate. A lose of static control, consciousness, and the deeper reflexes follows. Death finally ensues at 1.0 volume percent In about 4 hours and In progressively shorter periods at higher concentrations. Complete recovery can be effected by removal at any but the terminal stages.

According to this Bureau all four produced similar symptoms. Including excitement, loss of equilibrium, inability to walk, rapid pulse, convulsive rapid respiration with rales, frothy (often blood-tingedi exudate from nostrils. The signs of lung Irritation were not as pronounced for exposure to ethyl chloride as for the other compounds. The gross pathology was quite similar for ail four of these alkyl halides and was characterized by con gestion, hemorrhage, and edema of the lungs, and by Injury to the vascular system, us shown by the tendency toward hemorrhage. Congestion was present In the organs of all groups, but parenchymal degeneration was most marked in those exposed to methyl-bromide vapors.

Methyl Formate Methyl formate Is used in fumigants. It has also been considered for use as a high boiling refrigerant for household appliances. The United States Bureau of Mines studied the acnte responses of guinea pigs to a single exposure to vapors of methyl formate. According to this Bureau, the animals showed. In their order of occurrence, nose and eye irritation, retching movement, uncoordination, narcosis accompanied by uncoordinated movements of the extremities, and death. Methyl formate vapor was found to be irritating to the longs. Congestion and edema were the most constant and prominent findings after exposure which resulted in death. A hyperemia of the liver and kidneys and congestion of the surface vessels of the brain and adrenals usually accom panied the lung changes. Lung irritation was frequently found Immediately after exposure which did not cause death, but was absent in animals examined 4 to ID days following exposure. Men exposed for 1 minute to 0.15 percent vapor in air. according to the same authority, noticed the pleasant ethereal odor of methyl formate, but experienced no nasal or eye Irritation or other signs or symptom* While the odor of methyl formate Is distinct and noticeable in concentrations which are relatively safe from the standpoint of producing acute poisoning, owing to Its pleasant nature aod the occurrence of olfactory fatigne It Is doubtful whether the odor of methyl formate . will serve as an effective warning of harmful conditions of exposure. 54 OCCUPATION HAZARDS AND DIAGNOSTIC SIGNS 1 78.

According to this Bureau, pentanone produces in these animals narcosis, terminating in death In the higher concen trations. Symptoms are principally eye and nasal Irritation, followed by nar cosis. Animals that did not die during exposure, recovered. The principal gross pathological findings were congestion, edema, and hemorrhage of lungs, liver, and kidneys, as observed in the autopsies performed Immediately after exposure. Men momentarily exposed to LS and approximately 5.0 percent pentanone vapor, according to the same authority, pronounced the atmosphere extremely dlsagreeable because of irritation to the eyes and nasal passages.

A high frequency of cancer of the lungs in Czechoslovakian miners of uranium Is believed to be due to the radioactivity of the ore. Very little has been published on the effects on man of exposure to uranium salts. The con ditions reporeed Include purpura of the legs, reduction of leukocytes, as well as diminution of red corpuscles, a reduction In urinary elimination of nitrated salts, and an increase In the chlorides.

Because the dermatoses form so large a proportion of all disabling occupational diseases the more important occupations exposed to agencies producing skin affections have been listed separatelv. A complete enumeration of such occupations would be impracticable. Almost any foreign substance can become a skin irritant if it is in continuous contact with the skin. Thus soap and water, which ordinarily do not irritate the skin, may cause severe dermatitis in laundresses. Under the dermatoses are included the effects on the skin of such causative agencies as poisonous and irritating chemicals, heat and cold, dust, radiant energy, friction, plants anu 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 right-handed people. The onset and development are usually sudden. The associa tion between occupational exposure and the dermatoses produced by some substances, particularly those which are primary irritants, such as caustic soda, chromic acid, and gasoline, is quite obvious. Many other substances, however, have no specific lesions or special pathology, and some are selective in the people in whom they cause injury, thus making it more difficult to associate the condition with occupational exposure. The excellent work bv Drs. Louis Schwartz and Louis Tulipan, entitled "Occupational Oiacaow pf tlw Skin," fully treats of the dis eases of the skin and the agencies involved in their causation. It should be consulted by anyone who has a need for an extensive work on the subject. Dr. R. Prosser White's book entitled "The Dermatergoses: or Occupational Affections of the Skin" is another very fine work. The data presented in this section are based largely on these two volumes. The following is a list of the more common occupations exposed to agencies causing dermatoses. It is a partial list only. Reference should also be made to the specific hazards listed for the occupation under consideration in section I. DERMATOSES Occupations Exposed to Specified Skin Irritant!
