NIOSH Testimony on Ethylene Dibromide by L. F. Mazzuckelli, February 9, 1984.
NIOSH 1984 Feb:8 pages
This testimony concerned the viewpoint of NIOSH regarding the occupational hazards presented by workplace exposures to ethylene- dibromide (106934) (EDB). EDB has been observed to be a potent animal carcinogen, producing tumors at the site of direct contact and at remote sites. NIOSH agreed that OSHA has sufficient data to warrant lowering the occupational exposure to EDB from the current recommended standard of 20 parts per million (ppm). However, NIOSH did not accept the 0.5ppm suggested limit as having any meaningful scientific basis. NIOSH also questioned the setting of a threshold when dealing with a carcinogen. NIOSH has recommended an 8 hour time weighted average concentration of 0.45ppm be set with a ceiling limit of 0.130ppm. OSHA has listed wholesale and retail food stores; automotive service stations; and distribution, storage and bulk handling of leaded fuel to be exempt. NIOSH expressed concern over the exemptions, particularly that of the food stores. NIOSH also discussed the proposed use of respiratory equipment and the sponsoring of medical surveillance.
