PEL of Benzene 29CFR 1910.1028 Sample Clauses

PEL of Benzene 29CFR 1910.1028. The current OSHA PEL for benzene is 1 part of benzene per million parts of air at a TWA concentration over an 8-hour work shift; the short-term exposure limit is 5 ppm in any 15- minute sampling period. NIOSH recommends that benzene be controlled and handled as a potential human carcinogen in the workplace and that exposure be reduced to the lowest limit. NIOSH recommended the exposure limit as 0.1 ppm at an 8-hour TWA and 1 ppm as a ceiling in any 15-minute sampling period (xxxx.xxx). ACGIH has designated benzene as a suspected human carcinogen having an assigned TLV of 10 ppm as a TWA for a normal 8-hour work day and a 40-hour work week (xxx.xxx, Centers for Disease Control, NIOSH 1988)
