The flame-resistant cotton in the FO9-32P is made FR by the application of flame-retardant chemicals. When exposed to flame or light sparks, FR cotton relies on a chemical reaction to extinguish the flame. Our standard FR cotton is tested to ASTM F1506 standards to maintain flame-resistant protection through 50 home washings.
