Criteria for a recommended standard: occupational exposure to n-alkane mono thiols, cyclohexanethiol, and benzenethiol.
Rockville, MD: 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. 78-213, 1978 Sep; :1-129
NIOSH recommends that employee exposure to thiols in the workplace be controlled by adherence to the following sections. The recommended standard is designed to protect the health and provide for the safety of employees for up to a 10-hour workshift, in a 40-hour workweek, during a working lifetime. Compliance with all sections of their recommended standard should prevent adverse effects of exposure to thiols on the health of employees and provide for their safety. Techniques recommended in the standard are valid, reproducible, and available to industry and government agencies. Sufficient technology exists to permit compliance with the recommended standard. Although NIOSH considers the recommended workplace environmental limits to be safe levels based on current information, employers should regard them as the upper boundaries of exposure and make every effort to maintain exposures as low as is technically feasible. The criteria and recommended standard will be reviewed and revised as necessary. Because of systemic effects, absorption through the skin on contact, and possible dermal irritation, "occupational exposure to thiols" is defined as work in any area where thiols are produced, processed stored, or otherwise used. If thiols are handled or stored in intact, sealed containers, e.g., during shipment, NIOSH recommends that only Sections 3, 5(a), and 6(g) of this proposed standard apply. If exposure to other chemicals also occurs, provisions of any standard applicable to the other chemicals shall be followed.
