Ethylene Oxide (EO) is an extremely flammable and volatile substance and is considered an occupational carcinogen by the National Institute for Occupational Safety and Health (NIOSH) and the U.S. Environmental Protection Agency (EPA).
As the federal government attempts to eliminate accidental releases and emissions, EO emissions are coming under increased EPA scrutiny. The main sources of environmental emissions involving EO are from controlled venting in an industrial facility or chemical plant; fugitive emissions from leaking tanks, valves, and other process equipment; grab sampling; and use as a medical sterilizer and fumigant.
Challenges associated with EO sampling include:
This illustration shows a traditional sample panel system with flow-through cylinder. It is widely used to sample EO and other highly toxic liquefied gases.
Traditional sample panel systems present these challenges:
At BIAR Samplings Systems, we offer a solution (see illustration) that addresses the issues outlined above while allowing the operator to reintroduce any excess sample to the process line and eliminate the need for EO disposal.
For a safer way to handle EO and other highly toxic liquefied gases…
