NIOSH Testimony on Arsenic by R. A. Lemen, July 17, 1982.
NIOSH 1982 Jul:4 pages
Evidence of the carcinogenicity of arsenic (7440382) prompted the recommendation by NIOSH in 1975 of an exposure limit of 2 micrograms/cubic meter (microg/m3) for a 15 minute sampling period. In 1978 the OSHA standard was set at 10microg/m3. More recently the data supporting an increased incidence of lung cancer due to arsenic exposure was used to determine a quantitative estimate of the risk to workers. OSHA concluded in 1982 from the quantitative assessment that between 7.7 and 25 excess deaths per 1,000 workers would result from lung cancer among employees exposed to arsenic at 10microg/m3 over a working lifetime. OSHA further indicated that through the use of appropriate hygienic controls, personal protective equipment, and good working conditions, exposures would be reduced beyond the 10microg/m3 limit and thereby reduce the number of increased cases of lung cancer arising from exposure. NIOSH contended that by this statement of reduced exposure through good work habits, OSHA was concluding that a significant risk still existed at the proposed level of 10microg/m3 and that a person who was acting in his own best interests would seek to lower that exposure level still further. NIOSH urged that the recommended exposure level of 2microg/m3 be reconsidered and accepted.
