NFPA 2112/CGSB 155.20 - Flash Fire
NFPA 2112 Standard on Flame-Resistant Clothing for Protection of Industrial Personnel Against Short-Duration Thermal Exposures from Fire, is a commonly used standard specification for the evaluation of flame resistant clothing. In the most recent edition of NFPA 2112, gloves and shrouds, hoods, and balaclavas are included; certification programs for these products are available. The standard is cited by OSHA for those drilling in the oil and gas industry and used throughout the world in refining, chemical processing, combustible dust exposures and other garments to protect from momentary flash fires.
The NFPA 2112 standard requires third party certification. ArcWear can provide pre-testing and this data can be used at with UL or SEI (the ASTM Certification Body).
Some companies certify to CGSB 155.20 the Canadian standard which has a few different test requirements specific to the colder climates of the Canadian oil sands. ArcWear performs self certification testing to CGSB 155.20 but most Canadian clients accept the NFPA 2112 third party certification from either UL or SEI which ArcWear partners with to provide third party accredited data.
