Three levels— AEGL -1, AEGL-2, and AEGL-3—are developed for each of five exposure periods (10 min, 30 min, 1 h, 4 h, and 8 h) and are distinguished by varying degrees of severity of toxic effects. 1910.1001 (a) (1) This section applies to all occupational exposures to asbestos in all industries covered by the Occupational Safety and Health Act, except as provided in paragraph (a) (2) and (3) of this section. 1910.1001 (a) (2) This section does not apply to construction work as defined in 29 CFR 1910.12 (b).Evaluating Exposure. Determinations of employee exposure shall be made from breathing zone air samples that are representative of the 8-hour TWA and 30-minute short-term exposures of each employee. Medical surveillance.

D. Blood lead level confirmed with a second blood analysis, at which employee may return to work.The RfC is an inhalation exposure concentration at or below which adverse health effects are not likely to occur. It is not a direct estimator of risk, but rather a reference point to gauge the potential for effects. At lifetime exposures increasingly greater than the reference exposure level, the potential for adverse health effects increases. (4) New Chemical Exposure Limits under TSCA. Under section 5 of the Toxic Substances Control Act (TSCA), any person who intends to manufacture (including import) a new chemical substance in the United States for commercial purposes must submit a premanufacture notice (PMN) to the EPA at least 90 days prior to manufacture (including …The SCOEL 8-hr time weighted average exposures represent levels to which an employee may be exposed via the airborne route for 8 hr per day, 5 days per week over a working lifetime which will not result in adverse effects on health of the worker or their progeny. ...
