NIOSH Testimony on Occupational Exposure to Ethylene Dibromide by J. D. Millar, November 21, 1983.
NIOSH 1983 Nov:16 pages
This testimony concerns the proposed rule from OSHA regarding occupational exposures to ethylene-dibromide (106934) (EDB). NIOSH has recommended that no worker be exposed to EDB at greater than period. Studies have demonstrated that EDB is a carcinogen, with experimental animals developing tumors following inhalation of EDB. OSHA has proposed an 8 hour time weighted average exposure concentration of 0.1ppm with a short term exposure limit of 0.5ppm. NIOSH agrees that a reduction of the current permissible exposure limit of 20ppm as an 8 hour time weighted average is necessary. Concern is expressed over the plan of OSHA to allow the use of negative pressure respirators. NIOSH does not believe that an adequate number of cartridges and canisters were tested under a sufficient variety of conditions to make this allowance. Medical surveillance and the use of chemical protective clothing are also discussed.
