The Portwest FR417 Bizflame Work+ FR Trousers are multi-norm protective trousers for work where flame, heat, electric arc and light chemical splash are all risks. They protect against radiant, convective and contact heat and are suitable to be worn in an ATEX environment.
The trousers are free of nickel and ferrous metal, so they suit sites that use metal detectors. Five pockets carry tools and essentials, and the extendable leg length lets you adjust the trousers to suit your height.
