ASTM F2733, Standard Specification for Flame Resistant Rainwear for Protection Against Flame Hazards, contains minimum performance specifications and other requirements for rainwear used to protect workers from hydrocarbon or petrochemical flash fires in wet conditions.
The intent of this standard is to outfit workers with products that will lower the percentage of body burn and burn severity from a 3 second flash fire, thereby increasing survivability.
Similar to its ASTM F1891 counterpart for arc flash rainwear, key performance requirements of ASTM F2733 include:
NASCO industries is a leading manufacturer of FR raingear in the USA; watch NASCO’s video of flash fire raingear testing according to ASTM F2733:
NFPA 2112 is often seen as the parallel, or complementary, standard to ASTM F2733 as both set forth minimum requirements to maximize protection for workers facing flash fire hazards. NFPA 2112 governs flash fire protective work shirts, pants, and coveralls while ASTM F2733 is specific to flash fire rainwear.
ASTM F2733 was last updated in 2009 and is available for purchase through ASTM.
If your workers face an arc flash hazard and are not exposed to flash fire, read our post on ASTM 1891, Standard Specification for Arc and Flame Resistant Rainwear for more information about arc protective rainwear.
