Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. 77-173, 1977 Jan; :1-148
Manual intended to help employers better understand the spirit and intent of existing and proposed Federal exposure monitoring regulations. NIOSH technical recommendations are given concerning ways of meeting the requirements with minimum burden to the employer while providing adequate protection to the exposed employees. Statistical sampling strategies are outlined to assist employers in developing efficient programs to monitor occupational exposures to airborne concentrations of chemical substances. Data analysis methods are given which assist in making better decisions regarding the relation of employee exposure measurement results to standards of safe exposure. Decision criteria are based on assumptions of normal and lognormal distribution models for sampling/analysis errors and for environmental fluctuations, respectively. The manual also discusses topics of industrial hygiene such as determination of the need for exposure measurements, recordkeeping, and the nature of effects and symptoms of toxic agents. Sampling strategies encompass selection of subjects as well as sampling times. (Contract No.099- 74-0075)
