Structural firefighting is a test in managing extreme conditions. On any given call, a firefighter faces a myriad of hazards – direct flame contact, intense radiant heat, physical abrasion and exposure to hazardous fluids and pathogens. To survive, their turnout gear must act as a sophisticated armour system that is simultaneously impenetrable to external threats but breathable, and comfortable enough, to enable the wearer to perform at their best.

The Three-Layer Defence System

Structural firefighting gear is engineered as a complex three-layer system where each component plays a vital role.

  • The outer shell is the first line of defence – providing primary flame resistance and thermal protection, as well as the abrasion resistance necessary to survive multiple physical hazards.
    The moisture barrier is arguably the most technical layer due to its breathable and liquid resistant properties. Its role is to prevent liquids and substances, like hose water, chemical or bloodborne pathogens, from entering the firefighter’s suit. This means it must keep harmful substances and liquids out while simultaneously allowing body heat and vapor from sweat to escape the suit. This is an extremely important function and without it, the firefighter is at risk of heat-stress related injuries and sickness and even skin burns caused by their own sweat.
    The thermal liner is the innermost layer which sits closest to the firefighter’s skin. The thermal liner acts as an air buffer that insulates the firefighter’s body against extreme temperatures, both hot and cold.

Protection in Action against Heat Stress

A significant risk in firefighting isn’t fire, but heat stress which can be caused by the weight and insulation of a firefighter’s gear. The CHARNAUD® FIRE-SAFE® AIR-LITE® Structural Firefighting Bunker suit is specifically designed to combat this. Because it is lighter than other turnout gear available on the market, it reduces the physical load on the wearer.

The suit offers outstanding water vapor transfer, allowing users to operate for longer periods below the critical body heat stress threshold. Its’ ergonomic design includes scuff-resistant reinforcement on high-impact areas like the shoulders, elbows and knees, ensuring longevity for the suit and better endurance for firefighters out in the field. Furthermore, an extended back section ensures full body coverage at the interface areas, with better ergonomics especially when crawling or climbing.
