Fire suit, which is sometimes known as ‘bunker gear’ and ‘turnout gear’, consist of several protective layers of heat-resistant synthetic materials called aramids. These suits must not only protect the wearer from obvious extreme heat and burns, but they must also allow air transfer (to let cool air into the suit and expel body-heated air away), as well as preventing moisture buildup inside the gear itself. There are three main layers to a fire suit: the outer shell, the moisture barrier and, lastly, the thermal layer.

wearer to remain mobile. This layer is often a combination of carefully woven fibers made of a fire-resistant variant of Kevlar called NOMEX. A tight weave ensures that the material resists ripping during often strenuous firefighting activity. It also offers a degree of moisture deflection.

 

Below the outer shell comes an essential moisture barrier, which prevents liquids and chemicals from passing into the suit. This material consists of a breathable fabric such as Breathe-Tex, sewn in with the NOMEX/Kevlar blend.

Third is a strong thermal layer made from Kevlar-based fibres woven into the material. Flames won’t penetrate

through this layer and it also absorbs around three-quarters of a fire’s heat. The temperature of a typical fire ranges from 400-800 degrees Celsius (750-1,470 degrees Fahrenheit).

 

 

Fire Suit Layers

Function of Outer Shell

The purpose of the outer shell is to protect the firefighter from direct flame while providing abrasion and tear resistance and some thermal protection. Outer shell fabric comes in a variety of fiber blends, weaves, and weights, which impacts break-open resistance, strength, abrasion resistance, flexibility, and durability.

Function of Moisture Barrier

The moisture barrier protects the firefighter from water and NFPA “common liquids” (chlorine, battery acids, aqueous film forming foam, gasoline, hydraulic fluid, and antifreeze fluid) and is also tested for resistance to blood borne pathogens. The moisture barrier is required to provide “breathability” – letting perspiration move away from the wearer. This layer is made from an engineered membrane laminated to a woven or non-woven substrate.

Function of Thermal Liner

The thermal liner provides most of the thermal protection from ambient heat – the more thermal protection, the longer it will take for the firefighter to feel the heat. Thermal liners typically consist of a lightweight woven face cloth lining facing your body quilted to one or more layers of insulating non-woven batting.

The face cloth is made from a variety of fibers in spun (like cotton) form or filament (like fishing line) or a combination of the two. With more filament fiber, the lining fabric slides more easily against your body, which makes the gear more comfortable as well as making it easier to slide in and out of your gear.

The batting is typically a one-layer needle punch (like felt) or two or more layers of a spun lace (hydro-entangled) which is lighter and more flexible.

How Thermal Performance and Breathability Tested

Both the thermal protective performance and the “breathability” are tested on the base three-layer composite that makes up the turnout gear. The TPP test was introduced in the 1986 edition of NFPA 1971, with a minimum performance rating of 35, which remains the required test value today. In this test, samples of the three-layer composite are subjected to a bank of quartz lamps simultaneously with direct flame exposure, simulating flashover conditions.

The TPP value is determined strictly by the three material layers specified and is not impacted by design or construction. Different combinations will yield different results and, roughly speaking, if you take the TPP value of any three-layer ensemble and divide it in half, this would be the number of seconds of escape time for a firefighter caught in this environment before he would receive a second degree burn.

The second test, total heat loss (THL) is often referred to as the breathability test. The THL test was first introduced in the 1997 edition of NFPA 1971 as an annex item and became a requirement in the 2000 edition. This test is run on a guarded sweating hot plate and measures the ability of the same three base layers to allow heat to pass through the composite.

Not surprisingly, these two tests are like a see saw; in the TPP test we are measuring the ability of the layers to deter heat from the outside environment entering through the system, and in the THL test we are measuring the ability of these same three layers to dissipate body heat from the inside to the outside.

What is Firefighter Turnout Gear?

One of the definitions of “turnout” in the American Heritage Dictionary states: “An outfit or array of equipment, especially that worn by a firefighter.”

TURNOUT COAT

The early use of long trench coats, made of leather or canvas and later made of rubber, was the forerunner of modern turnout jackets. Back then firefighter coats had felt or wool liners to provide warmth in the winter. These felt and wool liners later evolved into the thermal protection liners found in today’s modern coats.

FIREFIGHTER PANTS

Firefighter’s turnout trousers (as well as the jackets) are made of different layers of fire-resistant materials to provide protection from extreme heat. The pants, when not in use, are usually stored open around the boots for immediate access when needed. In this way, a firefighter may just step into each boot and pull the pants up quickly.

TURNOUT BOOTS

Few professions demand such rugged and specifically manufactured footwear as firefighters, since they protect firefighters’ feet, ankles, and lower legs from many hazards.

TURNOUT GLOVES

Firefighters wear thick, leather gloves to protect their hands from burns, cuts and scratches.

TURNOUT HELMETS

In the early 1800s, felt caps were worn, but were more for decoration than service since this early headgear did not provide any protection against flame or head injury. At least it did keep water off the firefighter’s face.

Helmets protect a firefighter’s head from fire, falling debris, scalding water and extreme temperatures. Firefighter helmets have a chin strap to keep it in place, a visor on the front to protect the firefighter’s eyes and flaps to protect their ears.

SELF-CONTAINED BREATHING APPARATUS

Out of everything that firefighters wear, the Self-Contained Breathing Apparatus (SCBA) provides the highest level of protection. SCBA delivers air to the firefighter through a full face mask and is worn to protect against smoke inhalation, toxic fumes, and superheated gases.

PERSONAL ALERT SAFETY SYSTEM (PASS)

A Personal Alert Safety System (PASS) is commonly worn independently or as a part of the SCBA to alert others when a firefighter stops moving, which can assist another firefighter or rapid intervention team (RIT), in locating the firefighter in distress.
