Breakthrough Times for Footwear (Onguard® Chart)
NFPA-National
Fire Protection Association) To pass the applicable boot requirements
for NFPA 1991, 2000 edition, boots are independently tested to verify
compliance. Boots must resist permeation for 1 hour or more against
each chemical in the NFPA 1991, 2000 edition battery. The battery
consists of 15 chemical liquids and 6 chemical gases. The boots must
also pass a flammability resistance test. Hazmax® kneeboots have
successfully passed all of these tests.
