NIOSH Testimony on the Occupational Safety and Health Administration Proposed Rule on Occupational Exposure to Ethylene Oxide by J. D. Millar, June 22, 1983.
This testimony concerns the opinions of NIOSH concerning the proposed standard from OSHA. NIOSH generally supports the efforts to reduce the PEL for ethylene-oxide (75218) (EtO), but feels that the medical surveillance provisions of the proposed rule would not contribute to a reduction in risk. Concerning suitable methods for determining compliance with EtO permissible exposure limits, NIOSH suggests the procedure of Qazi and Ketchem of the Union Carbide Corporation, which has as its lower limit 3 parts per million. The possibility of lifestyle factors entering into the increased risk for cancer from exposure to EtO was discussed as well as proposed medical surveillance provisions, the use of personal protective equipment, the usefulness of field tests, the extent of the routine physical examination, the incidence of quadriradial or other chromosome aberrations and sister chromatid exchanges in peripheral lymphocytes over time after exposure to EtO, and circumstances for the wearing of respirators.
