Environmental and breathing zone samples were analyzed for ethylene- oxide (75218) at the Florida State Archives (SIC-8411), Tallahassee, Florida in November, 1984. The evaluation was requested to determine if an ethylene-oxide fumigator could be operated safely in view of the change in the OSHA standard from 50 to 1 part per million (ppm). Ventilation measurements were made. Ethylene-oxide was found to be leaking from the fumigation cylinder; associated plumbing produced potential exposures up to at least 500ppm during the evacuation cycle. Ethylene-oxide concentrations in the restoration and photography laboratories which shared common plumbing with the fumigator were 1 to 8ppm. A sample taken on a day when the fumigator was not operating showed 0.6ppm ethylene-oxide in the area near an ethylene-oxide cylinder. Breathing zone concentrations ranged from non detectable to 0.20ppm. The ventilation system dedicated to the fumigation operation worked well. The fumigation area was under sufficient negative pressure to prevent contamination of other parts of the building. The authors conclude that a health hazard exists if the fumigation system is operated without additional controls. Recommendations include adding local exhaust ventilation and using respiratory protection devices.
