Portwest FR56 Red Bizflame Offshore Trousers

The Portwest FR56 Red Bizflame Offshore Trousers are equipped to cope with a variety of industrial hazards, such as splatters of molten metal, arc flashes and radiant, convective and contact heat. The trousers feature inherent anti-static properties and the stripes of reflective tape help to increase their visibility in low light conditions.

What Can the Red Bizflame Offshore Trousers Do for Me?

The trousers have many helpful features:

  • Flame/Heat Resistant: Class 2 welding protection from molten metal in addition to resistance to radiant, convective and contact heat
