Emissions Monitoring

Under the Clean Air Act amendments of 1990, certain “major sources” and “area sources” using ethylene oxide must ensure that the concentration of ethylene oxide emitted into the atmosphere is below a threshold limit set by EPA regulation CFR 40 Subpart 63. Typically, the exhaust ethylene oxide from sterilizers passes through a two part scrubber system before being vented to the outside. Regulated facilities are required to demonstrate that they are emitting less than 1 ppm of ethylene oxide into the atmosphere, which requires a means to monitor the concentration emitted after the second phase of the scrubbing process.

ChemDAQ’s Steri-Trac® Emissions Monitoring System includes an Emissions Monitoring Control Unit (EMCU) to manage the flow of ethylene oxide gas samples, an EO sensor to measure gas concentration in the exhaust and a DAQ™ Central Monitoring System to calculate and report the 24-hour daily ppm average. The Central Management System also has enhanced graphics for trend analysis, alarm notification and record keeping.

For companies that have installed ChemDAQ’s Steri-Trac® ambient air monitoring system, the EMCU is easily added-on, allowing the facility to monitor employee safety and emissions from a single platform.
