"The recommended standard is given limiting employee exposure to less than 15 milligrams of hydrogen-sulfide (7783064) per cubic meter of air (10ppm) during a 10 minute sampling period for up to a 10-hour work shift in a 40-hour workweek with evacuation of the area if the concentration equals or exceeds 70 milligrams per cubic meter. In addition, standards are given for medical surveillance, labeling and posting, personal protective equipment, work practices, sanitation, and monitoring and recordkeeping. The criteria for the standards are also given, including extent of exposure in the United States, historical reports of exposure, effects on humans, epidemiological studies, animal toxicity, correlation of exposure and effect, carcinogenicity, mutagenicity, teratogenicity, effects on reproduction, environmental concentrations to which workers have been exposed, various attempts at controlling exposure, environmental sampling and analytical methods, biological monitoring, work practices and safety precautions for handling carbon-disulfide, the bases upon which previous and the present standards are recommended, and research needs. Appendices give the recommended air sampling method, analytical method, specifications for monitors, material safety data sheet, and NIOSH interim work practice recommendations for the gas and oil industry issued in August, 1976. Tables give physical and chemical properties, occupations with potential exposure, and calibration setup for personal sampling pump. (Contract No. 099-74-0031)" - NIOSHTIC-2
