What standards does Bulwark apparel follow for workers exposed to flash fire hazards?

The NFPA® 2112 Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire and its companion standard, NFPA 2113 on Selection, Care, Use, and Maintenance of these garments specify design, performance, certification requirements, and test methods for flame-resistant garments for use in areas at risk from flash fires. Third party certification of garments is also required.

  • In addition to third-party certifications of garments, flame resistance of each fabric layer is required to be tested as received and after 100 cycles of washing and drying and/or dry cleaning.
  • The Thermal Protective Performance (TPP) must be tested and a minimum TPP rating of 6.0 is required for “spaced” and 3.0 for “contact.”
  • Finally, coveralls made to a standard pattern from candidate fabrics are tested for overall flash fire exposure on an instrumented mannequin in accordance with ASTM Test Method F1930. The exposure heat flux is 84 kW/m² (2.02 cal/cm²/sec) with an exposure time of 3.0 seconds. The average total predicted body burn must not exceed 50%.

NFPA 2113 provides guidance in the selection and specification of flame-resistant garments, including workplace hazard assessment. Other sections cover use and care and maintenance recommendations. Canadian General Standards Board (CGSB) CAN/CGSB 155.20, Workwear for Protection Against Hydrocarbon Flash Fire is the Canadian
flash fire standard. The Canadian standard requires that flame resistance, heat resistance and thermal shrinkage be tested and that the garment label be in both English & French. For single layer garments, the TPP values for both spaced and contact tests must be reported on the garment label.
