And not just in Vernon — air regulators are monitoring ethylene oxide levels at more than a dozen facilities in Greater L.A.
What is ethylene oxide and who monitors it?
Because it can be used on a wide range of materials, ethylene oxide is well-suited for sterilizing medical equipment. But public health officials say long-term exposure to it can increase one’s risk of developing certain cancers, as well as reproductive issues.
The South Coast Air Quality Management District (SCAQMD) is responsible for monitoring the air and enforcing regulations in L.A., Orange, Riverside, and San Bernardino counties.
There are currently 15 facilities that use ethylene oxide to sterilize medical equipment under the agency’s jurisdiction, according to Susan Nakamura, SCAQMD’s chief operating officer.
