US Occupational Safety & Health Administration (OSHA)

OSHA has confirmed that garments that meet the requirements of ASTM F1506 are in compliance with OSHA 29 CFR 1910.269 Electrical Power Generation, Transmission and Distribution, with regard to garments not contributing to burn severity. ASTM F1506 is a minimum industry standard.

By utilizing FR garments, electrical utilities can comply with OSHA requirements and avoid potentially more serious burn injuries from garment ignition.
