NIOSH Testimony on Occupational Exposure to 1,3-Butadiene by J. D. Millar, September 27, 1991.
NIOSH 1991 Sep:8 pages
This testimony contains the comments of NIOSH regarding the proposed rule on occupational exposure to 1,3-butadiene (106990). The testimony concerns a risk assessment using a recent National Toxicology Program bioassay in B6C3F1-mice, a reanalysis of an earlier case/control study, an explanation of why NIOSH certifies air purifying respirators for formaldehyde even though it recommends only the most protective respirators be worn for exposure to potential occupational carcinogens, a decision as to whether any further respirator cartridge breakthrough tests would be conducted for 1,3-butadiene by NIOSH, and a request for field notes from field studies and computer disks containing exposure data. The frequency of hematologic examinations following exposures and medical surveillance requirements were also considered.
