What Is Fire Resistant Clothing?
Fire protection clothing is protective clothing worn by firefighters and high-temperature workers when working near fire. It is used to insulate and protect the upper and lower torso, head, hands, and feet, including fire jackets, fire pants, fire hoods, and fire gloves As well as fire-resistant feet. It has the characteristics of fire resistance, heat insulation, abrasion resistance, folding resistance, flame retardant, and anti-radiation heat. The temperature of anti-radiation heat is up to 1000 .
