The National Institute for Occupational Safety and Health (NIOSH) has established a recommended exposure limit (REL) of 0.1 ppm (parts per million) over a 10-hour workday in a 40-hour workweek, and 15 ppm for short-term exposure of 15 minutes. The organization also specifies that an 800 ppm exposure poses an immediate risk of death or serious health effects.

Occupational EtO Exposure Limits

The Environmental Protection Agency (EPA) considers EtO one of the most potent airborne carcinogens, even at very low concentrations.

In contrast to NIOSH, the Occupational Safety and Health Administration (OSHA) has established a limit of 1 ppm EtO over an 8-hour workday in a 40-hour workweek and 15 ppm for short-term exposure of 15 minutes. However, NIOSH estimates that even long-term exposure at 1 ppm can pose a significant cancer risk over a worker’s lifetime. That means that even low-level exposure can increase the risk of cancers like lymphoma, leukemia, breast cancer, and stomach cancer because EtO is a genotoxic carcinogen.

The conclusion is that any exposure above 0.1 ppm (NIOSH REL) is considered unsafe for extended periods. Additionally, short-term exposures exceeding 5 ppm are hazardous for periods exceeding 15 minutes. People living near sterilization facilities or plants using EtO can be exposed to trace levels of the chemical gas, measured in parts per million.
