FR Clothing

FR clothing costs more because the fabric itself is engineered or treated to resist ignition, which involves more specialized materials and manufacturing than standard cotton or polyester. The higher upfront cost reflects the protection built into every fiber, along with certification testing that regular workwear doesn't go through.

Most FR clothing can be tumble dried on low heat, but high-heat ironing directly on the fabric — especially over any printed logos — should generally be avoided since excessive heat can affect certain fabric treatments. Always check the specific care label on the garment, since instructions can vary slightly between fabric types like cotton and modacrylic blends.

Start by confirming the exact certification (NFPA 2112, NFPA 70E, or both) and CAT rating your job site requires, then choose a fabric weight suited to your climate — lighter for hot conditions, heavier for cold or high-abrasion work. Fit matters too, since overly tight or overly loose FR clothing can affect both comfort and how well it performs during a thermal event.

No, FR clothing is designed to reduce burn injury severity from flash fire and arc flash exposure by resisting ignition and self-extinguishing, but it isn't fireproof and won't protect against prolonged direct flame contact or extreme heat exposure indefinitely. It's meant to give you critical seconds to escape a hazardous situation, not eliminate all risk from fire.

Altering FR garments with non-FR thread can create a weak point at the stitched area, since regular thread doesn't carry the same flame-resistant properties as the fabric. If alterations are necessary, using FR-rated thread is the safer approach to keep the garment's protection fully intact.

Having 3 to 5 sets of FR clothing in rotation is common for a standard 5-day work week, giving enough time for proper washing and drying between shifts without cutting corners on care. Rotating multiple sets also reduces wear on any single garment, helping the whole wardrobe last longer overall.
