Can ethylene oxide be used for sterilization?
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.
Is EtO sterilization banned?
25, 2019 — In 2005, the U.S. Environmental Protection Agency considered banning ethylene oxide in new sterilizing facilities because of the cancer risk it posed to residents who lived around the plants.
Why is EtO harmful?
Both human and animal studies show that EtO is a carcinogen that may cause leukemia and other cancers. EtO is also linked to spontaneous abortion, genetic damage, nerve damage, peripheral paralysis, muscle weakness, as well as impaired thinking and memory.
Is ethylene oxide illegal?
Failure to follow the label is a violation of federal law. EPA’s Office of Pesticide Programs 2020 draft risk assessment for ethylene oxide concludes that EtO poses inhalation risks of concern and that additional mitigation measures are necessary to protect workers’ health and surrounding communities.
What are the hazards of ethylene oxide?
Ethylene oxide (C₂H₄O) is a flammable gas with a somewhat sweet odor. Exposure to ethylene oxide may cause headache, nausea, vomiting, diarrhea, breathing difficulty, drowsiness, weakness, exhaustion, eye and skin burns, frostbite, and reproductive effects.
Which of the following are disadvantages of using EtO?
The main disadvantages associated with ETO are the lengthy cycle time, the cost, and its potential hazards to patients and staff; the main advantage is that it can sterilize heat- or moisture-sensitive medical equipment without deleterious effects on the material used in the medical devices (Table 6).
How much ethylene oxide is safe?
► Ethylene Oxide may polymerize (self-react) violently. OSHA: The legal airborne permissible exposure limit (PEL) is 1 ppm averaged over an 8-hour workshift and 5 ppm, as an excursion limit, averaged over a period of 15-minutes.
Is ethylene oxide harmful to the environment?
The Clean Air Act requires EPA to protect air quality and directs different approaches to address different types of air pollution. Ethylene oxide is a hazardous air pollutant, also referred to as a toxic air pollutant or air toxic. There are 187 different toxic air pollutants regulated by EPA.
Is ethylene toxic to humans?
EPA has concluded that ethylene oxide is carcinogenic to humans by the inhalation route of exposure. Evidence in humans indicates that exposure to ethylene oxide increases the risk of lymphoid cancer and, for females, breast cancer.
What are the drawbacks of ethylene oxide sterilization?
main disadvantages associated with ETO are the lengthy cycle time, the cost, and its potential hazards to patients and staff; the main advantage is that it can sterilize heat-or moisture- sensitive medical equipment without deleterious effects on the material used in the medical devices (Table 6).
What happens if you inhale ethylene oxide?
Acute (short-term) inhalation exposure to high concentrations of ethylene oxide can cause headache, dizziness, nausea, fatigue, respiratory irritation (e.g., coughing, shortness of breath, wheezing) and, in some cases, vomiting and other types of gastrointestinal distress.
How safe is ethylene oxide?
Exposure to ethylene oxide may cause headache, nausea, vomiting, diarrhea, breathing difficulty, drowsiness, weakness, exhaustion, eye and skin burns, frostbite, and reproductive effects. Workers may be harmed from exposure to ethylene oxide. The level of exposure depends upon the dose, duration, and work being done.
