Occupational Exposure to Hexavalent Chromium
The Occupational Safety and Health Administration (OSHA) proposes to amend its existing standard for employee exposure to hexavalent chromium (Cr(VI)). The basis for issuance of this proposal is a preliminary determination by the Assistant Secretary that employees exposed to Cr(VI) face a significant risk to their health at the current permissible exposure limit and that promulgating this proposed standard will substantially reduce that risk. The information gathered so far in this rulemaking indicates that employees exposed to Cr(VI) well below the current permissible exposure limit are at increased risk of developing lung cancer. Occupational exposures to Cr(VI) may also result in asthma, and damage to the nasal epithelia and skin. This document proposes an 8-hour time-weighted average permissible exposure limit of one microgram of Cr(VI) per cubic meter of air (1 mg/ m 3 ) for all Cr(VI) compounds. OSHA also proposes other ancillary provisions for employee protection such as preferred methods for controlling exposure, respiratory protection, protective work clothing and equipment, hygiene areas and practices, medical surveillance, hazard communication, and recordkeeping.
