Worker exposure to ethylene-oxide (75218), propylene-oxide (75569), isopropyl-alcohol (67630) and allyl-alcohol (107186) was surveyed at Union Carbide Corporation (SIC-2869) in South Charleston, West Virginia, on May 30 and June 1, 1978. The facility employed approximately 1,700 workers and had industrial hygiene, medical and safety programs. Pre-employment and periodic medical examinations were given. Employees were expected to use appropriate protective equipment supplied by the company. Personal air monitoring and sampling were conducted and analysis was performed by gas chromatography. Concentrations of ethylene-oxide, propylene-oxide, isopropyl-alcohol and allyl-alcohol ranged from 1.6 to 23, 0.2 to 2.5, 0.2 to 1.2 and 0.4 to 4.7 parts per million (ppm), respectively. OSHA standards for ethylene-oxide, propylene-oxide, and isopropyl-alcohol were 50, 100 and 400ppm for an 8-hour time weighted average exposure. Allyl-alcohol standards were not given. The authors note that the sampling results were below detectable limits or OSHA standards.
