Identification of High Risk Occupational Groups Using NOHS/RTECS.

NIOSH 1980 May:99-120
A method was developed for assessing the relative potential health risk of workplace chemical exposure to occupational and industrial groups. Data from the NIOSH Registry for the Toxic Effects of Chemical Substances (RTECS) and the National Occupational Hazard Survey (NOHS) were used to calculate a Hazard Risk Index for chemicals listed in both RTECS and NOHS. Algorithms were developed to rank order chemicals by their relative potential toxicological effect, to rank order chemicals by simultaneous consideration of their relative toxicity and the number of people exposed to each under industrial conditions, and to rank order industries and occupations by relative potential health risk due to aggregate chemical exposure. Methods for developing risk indices which emphasize specific outcomes, such as dermatitis or cancer, or which consider only certain types of animal or exposure route data were described. The authors conclude that the risk indices produced by the modelling procedure can be used by the occupational health community to prioritize occupational health research needs, to identify occupations and industries with unrecognized hazardous chemical exposure problems, and to assist in allocating health service resources.
