Current intelligence bulletin 20 - tetrachloroethylene (perchloroethylene).
NIOSH 1978 Jan; :1-12
On a recent study indicating that tetrachloroethylene (127184) causes liver cancer in mice, NIOSH recommends that it is prudent to handle the compound in the workplace as if it were a human carcinogen, while its carcinogenic potential at work is being further evaluated. The recommended NIOSH tetrachloroethylene exposure limit of 50ppm and the OSHA standard for occupational exposure of 100ppm, may not provide adequate protection from potential carcinogenic effects because they were selected to prevent toxic effects other than cancer. It is estimated that about 500,000 workers employed in dry cleaning establishments and other industries are currently at risk of exposure to the compound in the U.S. Suggested procedures for control of overexposure to tetrachloroethylene, and guidelines for personal protective equipment and personal hygiene are outlined.
