Trichloroethylene levels in the workplace are regulated by the Occupational Safety and Health Administration (OSHA). The occupational exposure limit for an 8-hour workday, 40-hour workweek, is an average concentration of 100 ppm in air. The 15-minute average exposure in air that should not be exceeded at any time during a workday is 300 ppm. The OSHA standards are based on preventing central nervous system effects after trichloroethylene exposure. For more information, see Chapter 7.

The American Conference of Governmental Industrial Hygienists (ACGIH) and the Occupational Safety and Health Administration (OSHA) recommend that the highest average amount of heptachlor in workplace air over an 8-hour workday for a 40-hour workweek not be more than 0.5 mg/m. For more information on standards and guidelines for heptachlor and heptachlor epoxide, see Chapter/. 

The Occupational Safety and Health Administration (OSHA) sets rules for cresol levels in the workplace. The occupational exposure limit for 8-hour workdays over a 40-hour work week is 22 milligrams of cresols per cubic meter of air (22 mg/m ), which is equivalent to 5 ppm. See Chapter 7 for more information on regulations and guidelines for cresols.

The Occupational Safety and Health Administration (OSHA) regulates levels of benzene in the workplace. The maximum allowable amount of benzene in workroom air during an 8-hour workday, 40-hour workweek is 1 part per million (ppm). Since benzene can cause cancer, the National Institute for Occupational Safety and Health (NIOSH) recommends that all workers likely to be exposed to benzene wear special breathing equipment (NIOSH 1974). For more information on federal regulations, see Chapter 7.
