    potentially higher than average risk of exposure to ethylene oxide include sterilization technicians and industrial workers involved in the manufacture and/or use of ethylene oxide. 5.2 PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL . 5.2.1 Production . Ethylene oxide is primarily produced through ethylene oxidation with silver catalyst (Khan et al. 2002; Parod 2014). Ethylene and oxygen

  • Ethylene Oxide Overview Occupational Safety and

    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. It is also used as a fumigant in certain agricultural products and as a sterilant for medical equipment and supplies. Unfortunately, EtO possesses several physical and health hazards that merit special attention. EtO is

  • ETHYLENE OXIDE World Health Organization

    Most of the data on occupational exposure are related to the production of ethylene oxide and its use in industrial and hospital sterilization. Data were not available on exposures that are incurred outside North America and Europe, where almost half of the global amount of ethylene oxide is produced (Table 1).

Chronic (long-term) exposure to ethylene oxide in humans can cause irritation of the eyes, skin, nose, throat, and lungs, and damage to the brain and nervous system. There also is some evidence linking ethylene oxide exposure to reproductive effects. EPA has concluded that ethylene oxide is carcinogenic to humans

    22.08.2018· In fact, one comprehensive lifetime exposure study of workers in ethylene oxide production facilities found no statistically significant excess cancer risk due to ethylene oxide exposure. A similar result was found in Michigan when the state analyzed the population near a facility that used ethylene oxide in Grand Rapids.

    Main Routes of Exposure: Inhalation. Inhalation: VERY TOXIC. Can cause severe irritation of the nose and throat. Can harm the nervous system. Symptoms may include headache, nausea, dizziness, drowsiness and confusion. A severe exposure can cause unconsciousness. Skin Contact: CORROSIVE. The gas irritates the skin. Direct contact with the liquefied gas can chill or freeze the skin (frostbite).

  • Ethylene oxide Wikipedia

    Ethylene oxide is an organic compound with the formula C 2 H 4 O.It is a cyclic ether and the simplest epoxide: a three-membered ring consisting of one oxygen atom and two carbon atoms.Ethylene oxide is a colorless and flammable gas with a faintly sweet odor. Because it is a strained ring, ethylene oxide easily participates in a number of addition reactions that result in ring-opening.
