What does ETO stand for in treatment?
Sep 18, 2016 · Overview. ETO is a colorless gas that is flammable and explosive. The four essential parameters (operational ranges) are: gas concentration (450 to 1200 mg/l); temperature (37 to 63°C); relative humidity (40 to 80%) (water molecules carry ETO to reactive sites); and exposure time (1 to 6 hours).
