DHHS (NIOSH) Publication No. 81-111 |
 | | These recommendations are based primarily on a Chemical Industry Institute of Toxicology (C I I T) study in which laboratory rats and mice exposed to formaldehyde vapor developed nasal cancer, and are supported by a New York University study where rats exposed to a mixture of formaldehyde and hydrochloric acid vapors developed nasal cancer. |
 | | In 1976, NIOSH recommended, based upon the irritant effects of formaldehyde, that employee exposure to formaldehyde in the occupational environment be controlled to a concentration no greater than 1.2 milligrams per cubic meter of air (1 ppm) for any 30-minute sampling period. |
 | | Based on these results, NIOSH recommends that formaldehyde be handled in the workplace as a potential occupational carcinogen. |
