Toxic Off-Gases from Fires Detection Exposure Limits

Refrigerant HistoryCFC RefrigerantsIdeal RefrigerantsToxicityAcute Versus Chronic RisksFlammabilityToxicity and Flammability of RefrigerantsNearly all of the historically used refrigerants were flammable, toxic, or both. Some were also highly reactive, resulting in accidents (e. g., leak, explosion) due to equipment failure, poor maintenance, or human error. The task of finding a nonflammable refrigerant with good stability was given to Thomas Midgley in 1926.With his associates Albert Leon Henne and Robert Reed McNary, Dr. Midgley observed that the refrigerants then in us…See more on epa.govWhat are the most common toxic gases in confined spaces? the toxic gas concentration exceeds the PEL the atmosphere is hazardous. The OSHA PEL for carbon monoxide is 50 ppm, calculated as an 8-hour TWA limit. The NIOSH Recommended Exposure Limit (REL) consists of a two part definition, an 8 hour TWA limit of 35 ppm, and a ceiling limit of 200 ppm.
