Standard Performance Specification for Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Arc and Related Thermal Hazards.
Most popular FR fabrics today are blends of different fibers. These may include fabrics that have difference amounts of “inherent” or “treated” fibers—or even non-FR natural fibers.
The NESC covers workers during the installation, operation or maintenance of electric supply and communication lines and associated equipment. The 2007 version now contains rules that cover the use of FR clothing.
An industry standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire.
NFPA 652 is a brand new document addressing combustible dust, and was written to be an “umbrella” standard over all the existing industry-specific dust standards. The Standard on the Fundamentals of Combustible Dust was published in August 2015.
Standard for Electrical Safety Requirements for Employee Workplaces.
Clothing designed to be worn for work activities where significant exposure to molten substance splash, radiant heat, and flame is likely to occur.
Clothing designed for continuous wear in designated locations where intermittent exposure to molten substance splash, radiant heat, and flame is possible (as defined by ASTM Standard F1002).
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.
“Inherent” fibers tend to be synthetic fibers that have been engineered to embed the flame resistant properties within the fiber.
Most “treated” products begin as naturally occurring flammable substances—usually cotton or other cellulosics. Humans engineer the FR in these substances.
