What Is Firefighter Turnout Gear Temperature Rating (Heat Rating)?

Firefighter in Turnout Gear with Fire Nozzle

A firefighter turnout gear temperature rating is a heat-rating index (thermal protective performance rating) that measures the ability of your thermal protective material to protect you from high thermal exposure.

The heat rating, or degradation temperature, is when the fibers in the gear materials are completely destroyed. Firefighter turnout gear temperature ratings are not a threshold measurement of the temperature a human can withstand. Degradation temperatures are not survivability temperatures.

Yet turnout gear, also called bunker gear, is still critical to firefighter protection.

What Protection Does Turnout Gear Provide?

Although turnout gear provides limited protection to your body, it’s still one of the most important “tools” a firefighter has. Turnout gear will decrease the risks of harm from heat and flame, body fluids, cuts and abrasions, liquid splash from fireground chemicals, and other hazardous materials. Fire burns at temperatures up to 2,000° F (1,093.3° C) or higher. Stay protected with turnout gear during structural firefighting. It won’t make you invincible, but it does improve your chances of survival.

What Is the NFPA Standard for Turnout Gear?

There are numerous tests turnout gear must pass to be NFPA 1971 certified, not just heat resistance thresholds. Tear resistance, corrosion resistance, retro-reflectivity, breaking strength are just a few of the other tests.

The standard Thermal Protective Performance (TPP) requirement on turnout gear for structural firefighting is a Minimum 35 cal/cm2 TPP rating; 17.5 seconds to a second-degree burn.

The standard Total Heat Loss (THL) requirement on turnout gear for structural firefighting is a Minimum of 205 W/m2.

What Is a Compression Burn?

Moisture in your turnout gear and compression of its insulating air space may allow heat to travel through at a high rate, which results in a burn. Water adds weight and transfers heat.

Our turnout gear provides a moisture barrier. LION turnout gear uses IsoDri, which makes your gear lighter, absorbs less water, and its insulated air helps prevent compression burn.

How to Wash Firefighter Turnout Gear

NFPA recommends turnout gear undergo an advanced cleaning bi-annually and routine cleaning after each emergency response. Our blog offers more information on how to wash your turnout gear.

How Often Should You Replace Your Turnout Gear?

Retire and replace any gear that shows disrepair. You should inspect your turnout gear daily and your department should conduct bi-annual advanced inspections. The typical life expectancy of turnout gear is 5–7 years. Knowing your turnout gear temperature rating can help you to select the right gear for the job.
