The primary physiological effect of abnormal temperatures is the disturbance or the heat-regulating system of the body. Heat dilates the blood vessels on the surface of the body, increasing the supply of blood in this region. Cold, on the other hand, constricts the blood vessels, causing a diminished blood supply on the body surface. Continuous abrupt changes from one extreme of temperature to another may cause serious congestion of the internal organs, the heat-regulating system of the body not being capable of adapting itself to sudden variations. It is in this way that a cold draft, which causes a sudden variation of the temperature, may produce neu ralgia, paralysis, and respiratory diseases. Extremes of tempera ture may produce pathological changes by direct action. Thus, ex treme dry heat will cause conjunctivitis, cataract, and the familiar sunburn. Extreme cold may cause frostbite and eczema. With the above data in mind, abnormalities of temperature have been clas sified under only two headings; namely, "Sudden variations of tem perature" and "Extreme dry heat." Extreme cold has not been listed as a distinct hazard, because a 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 division " Extreme dry heat" 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 disease due to exposure to extremes of tem perature consists, obviously, in the avoidance of sudden variations of temperature. Drafts are particularly hazardous, and may he practically eliminated by the use of vestibule and storm doors. Workers in cold processes should keep active and avoid chill. The hot-process worker should allow his body to cool off gradually after completion of the day's work. He should carefully regulate his diet, drinking plenty of water and avoiding meats. As direct pre ventive measures for the effects of extreme heat, it is advisable to make use of shields, helmets, goggles, water-cooled furnace door--, exhaust systems, cold air, fans, etc. 88062*--22------- 3 11 12 OCCUPATION HAZARDS AND DIAGNOSTIC SIGNS.

In building tunnels, laying deep foundations for large buildings, etc., it is necessary for the work to be carried on under increased air pressure in order to prevent the entrance of water into the excava tions. The laborer is lowered gradually and at short intervals t lie LIST OF HAZARDS, ETC., AND PREVENTION. 13 pressure of the air in the compartment is increased. The first sen sation of compression is felt on the eardrums, which may be relieved by the act of swallowing. 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 coml pression the blood and tissue juices dissolve an increased amount of air. the gases of which are released when the pressure is suddenly decreased. The bubbles thus formed cut off the blood supply from various parts of the bodv by blocking up the capillaries. The symp toms of compressed air illness, the so-called " bends." are the result. Workers in compressed air must follow strictly the rules governing gradual compression and decompression, especially the latter. It is not advisable for boys and for men over 40 years of age to work under high pressure. B. Csmprasaad Air. Hutch basard. Symptom, condition, or disease to lode for.

The moisture content of the air is very important for the proper adjustment of the physiologic processes of the body. Damp air will prevent the evaporation of moisture from the body and will there fore affect the body temperature. High humidity tends to increase the effects of high temperature. Moist cold air has the effect of un dermining the general vitality of the organism, weakening its re sistance to diseases of the respiratory passages, and to neuralgic and rheumatic affections. The same effects are noticed among workers around open tanks and vats, who are continuously workingin wet clothes. Excessive dampness suggests dry air as a hazard. The lat ter causes chapped skin and catarrhal conditions. It has not been listed among the hazards because it is not characteristic of any one occupation but is prevalent generally, especially during the winter months. When dampness is a feature of an industrial process the following precautions should be taken to avoid ill effects: (1) Provision of exhaust systems wherever steam is generated. (2) Provision of floors with drain channels to prevent the accu mulation of water. (3) Provision of adequate waterproof clothing, such as rubber boots, rubberized aprons, etc. Wherever there is dampness special measures should be taken to keep the humidity at its proper percentage. In this connection the wet-bulb thermometer is invaluable in determining the degree of moisture in the air. By circulating the air the effects of high humid ity may be mitigated. 14 OCCUPATTOtf HAZARDS AND DIAGNOSTIC SIGNS. C. Sampasss. Hsalthhaxsrd. Symptom, condition, or disease Co look lor.

SUIT. Dusts have here been divided into two kinds, according to their chemical composition, namely, organic and inorganic. The dif ference in symptoms listed under each is based on the findings of recent investigators that organic dusts do not cause pulmonary lesions. Dr. H. R. M. Landis1 has found that wherever fibrosis was. present in the lungs of men exposed to organic dust, the latter was always mixed with some form of mineral or metallic dust. Tobacco workers exposed to organic dust for years showed no pulmonary changes other than those found in people living in the city. Mineral and metallic dusts, however, produce fibrosis of the lung tissue, the extent of which depends on the time of exposure and the particular dust inhaled. Of the inorganic dusts, silica is the most harmful, producing serious pulmonary damage in a comparatively short pe riod of time, while the least "harmful are those which produce slight changes and then only after long exposure, for example, lime. coal, etc. The relationship between occupational dust and tuberculosis is rather a doubtful one. Authorities disagree as to the effect of fibrosis on the resisting power to the tubercle bacillus. Dust, by acting as a carrier of tne bacilli, may increase their number in the 1 3m article on "Tbs Pathologic*] sad Clinical lfanifMtattOBi Inflowing th* Inhalation of Dust " m Ths Journal of Industrial Hygiene, July, 1919, pp. 117-139. LIST OF HAZARDS, ETC., AND PREVENTION. 15 lungs. In this way, men exposed to dust may be in greater danger of contracting tuberculosis than others. Dr. H. R. M. Landis claims, however, that in the trades exposed to inorganic dust, mistaken diagnosis of pneumoconiosis swells the mortality statistics for tuber culosis. As a means of avoiding incorrect diagnosis of pneumoco niosis, Roentgen ray examinations of the lungs and sputum analyses are invaluable. There are four effective methods that may be used to prevent the inhalation of dust generated during 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 use of water to dampen the dust and thus prevent it from rising and filling the atmosphere. (2) The use of exhaust systems which remove the dust at the point of origin. (3) . The use of enclosing chambers in which the dust-producing processes are confined, being regulated from the outside. (4) The use of respirators ana helmets. In many cases it may be necessary to combine several of these measures effectively to prevent the inhalation of dust by the worker. n. Dust Health haxard. Symptom, condition, or disease to look tor.

X. UT1IXX LIGHT. Intense light is usually a product of a process associated with heat. Among the different kinds of light included under this heading are the arc light, furnace glare, glowing metal or glass, and X-ray. Poor illumination as a hazard is treated under "G. Poor illumination." Continuous exposure to strong light is not only irritating to the con junctiva, but may also cause a degeneration oi the retina and decom position of the visual purple. Repeated electric flashes of brilliant light have caused severe ophthalmia, retinitis, and even blindness. Glass blowers and steel puddlers, who have to look at a glowing molten mass, are apt to develop cataracts. It seems that the invisible ultra-violet rays and infra-red rays are responsible. The introduc tion of X-rays into the medical field has brought to light the highly dangerous character of the radiographer's work. Severe dermatitis and cancer may ensue after exposure to X-rays. The following protective devices prove effective in preventing the injurious action of extreme light: !1) Shields. 2) Helmets. 31 Goggles which eliminate the ultra-violet and infra-red rays. 41 Clothing which covers the skin completely. 5) X-ray apparatus should be inclosed as completely as possible with lead plates. LIST OF HAZARDS, ETC., AND PREVENTION.

INJECTION'S. There are many infectious diseases, such as tetanus, trachoma, and syphilis, which are often of occupational origin. They are not, how ever. specifically occupational; that is, they do not arise from a con dition caused bv an industrial process. Tne conditions which cause these diseases in industry are identical with those which cause them out of industry. The above-mentioned diseases have not therefore been included m this list of occupational infections. Those diseases which have been included arise primarily in occupational exposure. There are a number of other diseases which occur in occupations, but these are of such little numerical importance that they also have not been included. Besides the general rules of sanitation, the following measures are recommended: (1) Anthrax.--All hides and animal hair must be thoroughly sterilized. Foreign skins or hair should not be carried on the un protected 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 prevent ing the entrance of the hookworm through the skin. Infected soil should be disinfected and kept dry. The stools of infected individ uals must be disinfected immediately. (3) Septic infection.--Workers should avoid puncturing the skin. Cuts, scratches, or abrasions should be treated at once to avoid in fection. Men having open wounds should not be allowed to work with putrid material. 18 OCCUPATION" HAZARDS AND DIAGNOSTIC SIGNS.

O. 7001 ZZXTnCZHATXOV. The effects of poor illumination are not easily apparent. The hazard may be present in any plant, but is especially prevalent :n a limited number of occupations because of the peculiar conditions that make it difficult properly to illuminate tne workroom. Miner's nystagmus is the outstanding example of the effects of this hazard. Poor illumination is not only the cause of the conditions listed below but ia also an important factor in the causation of accidents. Artificial light is least harmful to the worker when it comes from overhead, reflected from the ceiling by inverted bowl-shaped re flectors. Light-colored walls and ceuings aid materially in properly illuminating a room. Special precaution must be taken to avoid glare. Alllights should be shaded so that only diffused light reaches the eye. LIST OF HAZARDS, ETC., AMD PREVEXTIOIT. ft. Poor XUnmlnatfan. 19 Health hazard.

Under this heading are included those muscle-strain conditions which are caused by the continuous repetition of movements, pres sure, or blows. This section is not concerned with the neurasthenic phenomena which are sometimes called occupational neurosis. Everyone is familiar with the muscular strain experienced in per forming for the first time some exercise, such as rowing, long walk ing, etc. Men newly introduced into a process requiring such re peated action are affected similarly but often much more severely, so as to disable them temporarily for the particular job. The in jury does not stop with muscular strain but may even cause in flammation of the surrounding sheaths or paralysis of the parts concerned. Many types of occupational neurosis may be avoided by working at a comfortable pace, avoiding fatigue. 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. Occa sional rest periods will do much towards the prevention of muscular pains`and cramps. X. Repeated Kotin, Praanze, Shook, Xto. Health hazard. Symptom, oondltloa, or disease to look lor.

J. POXfOMf. 'Hie continued introduction of new processes making use of new poisonous substances in industry makes this section of more and more importance. The enormous increase in the production of dye stuffs and other chemicals will no doubt show its effects on the workmen in the form of industrial poisoning. During the war thv increased production of trinitrotoluol and tetrachlorethane for an - 20 OCCUPATION HAZARDS AND DIAGNOSTIC SIGNS. plane dope resulted in a large number of cases of poisoning from these substances. For the data presented under this heading, the revised " List of industrial poisons," compiled by Sommerfela and Fischer for the International Association for Labor Legislation, has been drawn upon largely. The arrangement is similar.1 The mate rial in that list has been revised and brought up to date. Seyerul ?oisons have been added and all the occupations exposed are given or each poison. The symptoms are those given by recent investi gators. In order to avoid swelling the list of poisons to unwar ranted proportions, substances the effects of which are similar have been grouped. Thus, all nitro compounds of benzol and its homo- logues have been included under one heading and the same pro cedure has been followed with amido compounds. An endeavor has been made to limit this list to those substances the actions of which are mainly constitutional. The next section (p. 29) is devoted to the substances occurring in industry which act as skin irritants. Because of the very large number of substances in the latter class, it has not been possible to treat them as fully as the other poisons. To prevent industrial poisoning the following precautions should be taken: Personal cleanliness must be maintained. Workers must be instructed as to the toxicity of the substance handled. Frequent medical examinations of workers must be made to detect early symp toms of disease. Men should not be allowed to eat in workrooms where poisonous substances are handled. Work clothes should be removed at end of day's work. Proper lavatory facilities should be `i provided. Work clothes should receive special attention. The use / M * of gloves and boots are often necessary. Mechanical devices for 1 confining the poisons are of prime importance. (See also preventive i measures, under "Dust.") Fumes and gases should be taken care of by proper ventilation, the use of exhaust systems, fans, and 1 blowers. Men who work in an atmosphere polluted by poisonous fumes and gases should always wear gas masks properly suited for the obtaining conditions. i I. Yiliiu. Baalthbaiard.

Because of the fact that dermatoses form such a large proportion of all occupational diseases and are often disabling, the more impor tant occupations that are exposed to skin irritants have been listed separately. A complete enumeration of such occupations would be impossible. 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 dermatoses in washerwomen. The data presented below are a compilation of the literature on the subject, taken largely from Dr. R. Prosser White's compilation of " Occupational Affections of the Skin." Skin affections caused by different external irritants often show the same clinical picture. A number of occupational skin eruptions have no specific lesions or special pathology, which makes their dif ferential diagnosis very difficult. Most superficial industrial skin diseases show simply a difference in degree of catarrhal inflamma tion. depending on the intensity of the irritant. For these reasons the symptoms for each irritating substance have not been listed as has been done for the other hazards. Occupational dermatoses are characterized by their grouping, situ ation, mode of appearance, spread, and evolution. They crop up in series, retaining their initial type throughout, unless they are secondarily infected. They are most often local, except when they are a differentiating sign of the toxemias. The onset and develop ment are usually sudden. The inflammation is sharply outlined. Exudation is excessive and there is deep-seated edema. The erup tion usually predominates on the right side. There are many cases of dermatitis which are caused by physical agents, such as heat, cold, friction, etc. In this bulletin these condi tions are dealt with only as they are related to the hazards listed. Thus among the symptoms for " Extreme dry heat " and " Extreme., light " we find skin eruptions. The following is the list of the more common occupations exposed to dermatoses with the irritating substances concerned: Occupation* Zxpoiod te IpocIStd BMa Irritant*, Occupation axpoMd.
