By: Sarah D’Mello, Senior Product Safety Specialist
OEHHA, The Office of Environmental Health Hazard Assessment released a draft document in early 2023 regarding ethylene oxide.
Read more about the proposed changes and learn how to participate in the public comment period below.
Cancer Inhalation Unit Risk Factor
The Office of Environmental Health Hazard Assessment (OEHHA) released a draft document outlining the carcinogenicity data and updated cancer inhalation unit risk factor (IUR) for ethylene oxide.
Cancer IURs are used in the Air Toxics Hot Spots Program to estimate lifetime cancer risks associated with inhalation exposure to a carcinogen.
The public comment period will end on May 22, 2023. Comments can be submitted online.
Updated to the No Significant Risk Level
OEHHA is proposing to update the No Significant Risk Level (NSRL) for ethylene oxide. The proposed updated NSRL for ethylene oxide is 0.058 micrograms per day.
The updated NSRL reflects the current scientific information available for ethylene oxide. Exposures at or below the NSRL are exempt from the warning and discharge requirements of Proposition 65.
OEHHA must receive comments on the proposed regulation by May 23, 2023. Comments can be submitted here.
It is strongly recommended to submit comments electronically rather than in paper form.
