What is the vapor pressure of ethylene oxide?
Ethylene oxide is a colorless, flammable gas. It is highly soluble in water (1×106 mg/L at 20°C) and possesses a high vapor pressure (1.095×103 mm Hg at 20°C).

Is EtO heavier than air?
6. Unusual fire and explosion hazards: Vapors of EtO will burn without the presence of air or other oxidizers. EtO vapors are heavier than air and may travel along the ground and be ignited by open flames or sparks at locations remote from the site at which EtO is being used.
Is ethylene oxide gas heavier than air?
Ethylene oxide is soluble in water and organic solvents. provide adequate warning of hazardous concentrations. The odor threshold is 500 ppm, while the OSHA PEL is 1 ppm. The gas is heavier than air and can cause asphyxiation in enclosed, poorly ventilated, or low-lying areas.
What pressure is ethylene stored at?
Operating conditions of ethylene horizontal tank Operating pressure: 1.83 MPaG; operating temperature: -30 °C; liquid specific gravity: 0.483.
Is ethylene gas heavier or lighter than air?
lighter
Ethylene appears as a colorless gas with a sweet odor and taste. It is lighter than air. It is easily ignited and a flame can easily flash back to the source of the leak. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.
How fast does ethylene oxide evaporate?
After inhaling ethylene oxide it takes about 45 to 60 minutes for half of it to break down and be exhaled back out of the body (the “half-life”). That means that ethylene oxide will be completely eliminated from the body within 1-2 days to a week after being exposed.
What does EtO smell like?
Ethylene oxide (EtO) is a flammable, colorless gas at temperatures above 51.3 ºF (10.7 ºC) that smells like ether at toxic levels. EtO is found in the production of solvents, antifreeze, textiles, detergents, adhesives, polyurethane foam, and pharmaceuticals.
Is ethylene stored as liquid or gas?
Ethylene is used in the gas phase at ambient temperature but liquefied under the conditions of low temperature and high pressure during storage and transportation [12].
Is ethylene less dense than air?
Ethylene appears as a colorless gas with a sweet odor and taste. It is lighter than air.
Does ethylene oxide break down?
Less than 1% of the industrial production of ethylene oxide is used as a fumigant and sterilizing agent for a variety of purposes and materials which include hospital equipment and certain food. Ethylene oxide degrades in both the air and natural water.
Is ethylene gas lighter than air?
Ethylene appears as a colorless gas with a sweet odor and taste. It is lighter than air. It is easily ignited and a flame can easily flash back to the source of the leak. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.
What is EtO used for?
ETO is used in healthcare facilities to sterilize critical items (and sometimes semicritical items) that are moisture or heat sensitive and cannot be sterilized by steam sterilization.
What is the EtO process?
The basic ETO sterilization cycle consists of five stages (i.e., preconditioning and humidification, gas introduction, exposure, evacuation, and air washes) and takes approximately 2 1/2 hrs excluding aeration time.
Is ethylene oxide in the air?
Ethylene oxide degrades in both the air and natural water. In the air, oxidation via free radical formation is the most probable degradation pathway; the estimated half-life of this reaction ranges from 2 to 5 months. The half-life estimates for other degradation pathways for atmospheric ethylene oxide vary widely.
What is EtO in chemistry?
Ethylene oxide (EtO) is produced in large volumes and is primarily used as an intermediate in the production of several industrial chemicals, the most notable of which is ethylene glycol.
