This is the fourth post of a four-part series where we cover recommendations for compliance with OSHA 1910.132 FRC Flash Fire Memo.
The final, and least rigorous, approach for meeting the OSHA 1910.132 requirements would be to use garments that meet the arc flash requirements of NFPA 70E, or are otherwise determined to be flame resistant. NFPA 70E addresses electrical safety requirements necessary to safeguard employees.
All NFPA 70E garments are required to meet ASTM F1506 “Standard Performance Specification for Flame Resistant Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Electric Arc and Related Thermal Hazards.”
This specification has three core components:
Garments that meet NFPA 70E and ASTM F1506 may also meet NFPA 2112 or be Flash Fire Rated. Furthermore, garments that are neither NFPA 2112 compliant, nor Flash Fire Rated may actually provide more protection than those that are. However, without ASTM F9130 Manikin 3 second flash fire test results, it would be difficult to determine the level of protection.
By definition, any garment carrying a label stating that it meets ASTM F1506 is flame resistant. You should check the garment label to determine which standards a garment meets. As such, it would likely be considered FRC and would likely meet the OSHA 1910.132 requirement.
