Such special studies and training must have been sufficient in all of the above cognate sciences to provide the abilities (a) to rec ognize the environmental factors and stresses associated with work and work operations and to understand their effect on man and his well-being, (b) to evaluate, on the basis of experience and with the aid of quantitative measurement techniques, die magnitude of these stresses in terms of ability to impair man's health and well-being, and (c) to pre scribe methods to eliminate, control or re duce such stresses when necessary to allevi ate their effects " Scope Recognition of environmental factors and stresses which influence health requires that the industrial hygienist be familiar with work operations and processes The categones of stresses that interest him are (a) chemical-- American Industrial Hygiene Association Jour nal, 20 428-430 (Oct 1959)
