This is the level to which a worker can be exposed for up to 30 minutes while escaping from a hazardous atmosphere without serious permanent injury. 263. While … One of the most adopted sterilization processes uses ethylene oxide (EO), a highly reactive, toxic and flammable gas capable of sterilizing at ambient temperature, preserving those medical devices which cannot be exposed to moisture or high temperatures — like the ones made of polymers, plastics or those containing electronic components. Evidence in humans indicates that long-term exposure to ethylene oxide increases the risk of cancers of the white blood cells, including non-Hodgkin lymphoma, myeloma, and lymphocytic leukemia. ETO sterilization can take up to 12 hours due to its slow action upon microorganisms, and lengthy processing and aeration time. What is ethylene oxide? Based on this finding, the EPA moved ethylene oxide in 2016 from a list of chemicals that probably could cause cancer to a list of chemicals that definitely caused cancer. The disinfectant effect of ethylene oxide is similar to that of sterilization by heat, but because of limited penetration, it affects only the surface.

The U.S. Occupational Safety and Health Administration has information about limiting occupational exposure to ethylene oxide. In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent. Because ethylene oxide is highly explosive and reactive, the equipment used for its processing generally consists of tightly closed and highly automated systems, which decreases the risk of occupational exposure. At room temperature, ethylene oxide is a flammable colorless gas with a sweet odor. If you have a legal question regarding Ethylene Oxide, we can help.

Alarmingly, industry has … In smaller amounts, ethylene oxide is used as a pesticide and a sterilizing agent. While using this gas for moisture or heat-sensitive equipment would be safe for that equipment, it wouldn't necessarily be … “Ethylene oxide is not the first best choice to sterilize medical devices.” 1 Not permitted to be carried in limited quantities. Triangle Park, NC: National Institute of Environmental Health and Safety, 2016. In the United States, OSHA now requires employers to monitor the amount of Ethylene Oxide their employees are … It is not usually recommended for use on seeds (Joubert and Du Toit, 1965), nursery stock or any growing plants. Therefore, following disrobe, improvised wet In general, with higher levels of exposure to the chemical, more severe effects will occur. It is correct that too much exposure to ethylene oxide can carry health risks, including cancer. The ability of ethylene oxide to damage DNA makes it an effective sterilizing agent but also accounts for its cancer-causing activity. Stomach and breast cancers may also be associated with ethylene oxide exposure. October 1, 2020 By Nancy Crotti. EtO is both flammable and highly reactive. Unfortunately, EtO possesses several physical and health hazards that merit special attention. 2. EtO is used for items that are sensitive to moisture, heat, or radiation. MP9.
