[Docket No. H-057a] RIN: 1218 - AB16

Occupational Exposure to Cadmium

AGENCY: Occupational Safety and Health Administration (OSHA), Department of Labor.

ACTION: Final Rules

SUMMARY: The Occupational Safety and Health Administration (OSHA) hereby publishes a new standard for occupational exposure to cadmium, applicable to general industry and agriculture and maritime. A separate standard regulating exposure to cadmium in the construction industry was also developed, because the differences in job duration, exposure and worksite conditions warrant unique treatment. OSHA is publishing the construction standard at 29 CFR 1926.63.

The basis of this regulation is a determination by the Assistant Secretary that employees exposed to cadmium face a significant risk to their health from lung cancer and serious kidney damage at the current permissible exposure limits and that promulgating this standard will substantially reduce that risk. The information gathered during the rulemaking demonstrates that employees chronically exposed to levels of cadmium well below existing permissible exposure limits are at increased risk of developing kidney dysfunction and cancer.

The new standard establishes a single 8-hour time weighted average permissible exposure limit (TWA PEL) of 5 micrograms of cadmium per cubic meter (ug/m(3)) of air for all cadmium compounds, including dust and fumes. Employers are required to comply with this limit primarily by means of engineering and work practice controls. For a small number of industries, OSHA has also established separate engineering control air limits (SECAL) of either 15 ug/m(3) or 50 ug/m(3) as the lowest feasible levels above the PEL that can be achieved by engineering and work practice controls. Like the PEL for other industries, the SECAL, where applicable, must be achieved by engineering and work practice controls except to the extent that the employer can demonstrate that such controls are not feasible.

EFFECTIVE DATES: The new standards published today take effect December 14, 1992.
