RT Journal T1 Occupation hazards and diagnostic signs: A guide to impairments to be looked for in hazardous occupations. (revision of bulletin no. 306.) JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1939 FD June 17 VO 112 IS 24 SP 2559 OP 2559 DO 10.1001/jama.1939.02800240075033 UL http://dx.doi.org/10.1001/jama.1939.02800240075033 AB The third edition of this bulletin has been reissued to meet a steady demand. Nine hundred occupations, actually or potentially hazardous to the health of workers, are listed alphabetically. The hazards themselves are arranged according to a useful classification whereby symptoms, occupations in which they occur and methods of prevention are correlated. There is also a partial list of skin irritants identified with certain occupations. Physicians will find it time saving to consult this useful compilation as an introduction to more extended treatment in the standard textbooks on industrial health in the study of cases in which occupation is suspected as a contributor to poor health.
