Arc-Flash and Flash-Fire Garment Selection
CAT 2 identifies an arc-flash PPE category; it does not mean these jeans are suitable for every energized task or flash-fire exposure. The employer must complete the applicable hazard assessment and select a complete protective clothing system with an arc rating above the estimated incident energy. Confirm the FR428 garment label, fit, condition, compatible upper-body clothing, closures, layers, laundering instructions, and all other required PPE before use. Replace garments that are damaged, contaminated, or no longer serviceable.
