Turnout gear or "bunker gear" are terms used by many firefighters to refer to their system of outer protective clothing. "Bunker gear" and "turnout gear" can refer, depending on the context, to just the trousers and boots, and jacket, or the entire combination of personal protective equipment and personal protective clothing. The terms are derived from the fact that the pants and boots are traditionally kept by the firefighter's bunk at the fire station to be readily available for use.
The early use of long trench coats, made of leather or canvas and later made of rubber, was the forerunner of modern turnout jackets. Early coats had felt or wool liners to provide warmth in the winter. These liners later developed in basic thermal protection liners found in todays modern coats. Earlier rubber coats were much longer than today's modern turnout jackets, reaching down to a firefighters mid thigh and were worn with long rubber boots called "three-quarter boots" which came above the firefighter's knees. This interface of boot and coat left a large gap of protection against fire. This system has since been replaced by the modern combination of a jacket, pants with suspenders, and shorter rubber or leather boots, although some departments still wear the traditional old style of gear.
The combination of modern triple-layer turnout gear with self-contained breathing apparatus(SCBA), PASS device, and modern communications equipment made it more feasible and survivable to enter burning buildings. Modern turnout jackets and pants are made of fire resistant fabrics (mainly Aramids such as Nomex and Kevlar) or polybenzimidazole (PBI) fibers . The standard that the National Fire Protection Association has designated to firefighter protective clothing, NFPA 1971: Standard on Protective Ensembles for Structural Fire Fighting and Proximity Fire Fighting, which specifies "the minimum design, performance, safety, testing, and certification requirements for structural fire fighting protective ensembles and ensemble elements that include coats, trousers, coveralls, helmets, gloves, footwear, and interface components.
The materials used for the three layers in turnout pants and coats may vary but will very often include a Nomex/Kevlar combination of material. As an example, the materials used by the Los Angeles City Fire Department, as found in their 2005 recruit handout are as follows:
NFPA 1500 (Primary Guidelines for the Fire Service) and similar standards mandate features such as protective collars and sleeves to protect the fire fighter from exposure to heat, (hot or polluted) water and debris;
Once the need arises for actual firefighting protective equipment to be worn, also known as turnouts, a firefighter must properly wear protective equipment required. Turnout pants will be the first article of clothing that a firefighter will usually wear. Suspenders worn with the turnout pants should be the heavy duty type in order to stand up against such heavy weights and rigorous activities they will face. Most experienced interior firefighters (Firefighters that enter the structure in an emergency) will carry, in their turnout pant pockets, various tools and equipment as well as rope they may need during an emergency. You can expect to find a multipurpose tool in the cargo pocket of a firefighter. The turnout pants, when not in use, are usually stored scrunched down around the boots for efficient and fast access when they are needed. The firefighter may then step into each boot and pull up the pants and suspenders.
A turnout coat is the type of jacket typically worn by firefighters. Oversized pockets to allow for carrying tools and equipment, and reflective safety stripes to ensure that firefighters remain visible to each other. Protective coats will usually have Velcro or zipper functions which will enable a firefighter to properly and efficiently don this piece of gear. There is also a storm flap which covers this closure area and protects it against damage and loosening and as an extra measure to the fire fighter as these areas can be exposed to fire and heat. Wristlets, 4 inch (according to NFPA 1500) 100% Nomex coverings along the distal end of the coat arms in with the thumb joint will slip through, fit around the firefighters hand and provide redundant protection where the skin may show between the glove and coat. They are designed to prevent burns to the wrist, while preventing bunching and remaining flexible.
Usually pre-fitted inside the legs of the trousers are the firefighting boots, which can be made of either rubber or leather. When the trousers and boots are not being actively used, the trousers will fold down and out around the shins of the boots, ready for quick access for the firefighter. Due to the enormous amounts of potential hazards at a fire scene to the feet, turnout boots are required to be able to handle a variety of different burns and blows. All boots are required to be outfitted with safety toes and a puncture resistant midsole plate to prevent puncture from sharp objects that may be stepped on. Such emphasis on the midsole plate is made that IFSTA has deemed that “if there is doubt about midsole protection, [one should go as far as to] x-ray the boot.”
When helmets do not provide built-in protection for the ears, neck and part of the face a protective firefighting hood is worn by firefighters. These are fitted and designed to protect the firefighter’s ears, neck, and the parts of his face which are not protected by the SCBA mask.
They are designed to the guidelines set by NFPA 1975. Cal/OSHA Title #8 also has regulations in the state of California. They are made of Nomex Knit Fabric which weighs 6 oz./ Sq. Yrd.; they are most often double ply with only one seam running from the top center of the face opening, over the top and down the bottom of the bib. The Nomex Knit, which is standard, is why they are commonly referred to as Nomex hoods. First, the hood is tucked into the collar. The SCBA mask is then donned, and the hood pulled over the face seal to cover any exposed skin.
The design of helmets vary from fire service to fire service and depends on the brigade's or department's requirements. Some helmets are fitted with a face guard or shield to protect the firefighters face against heat, dust, water and debris when working on a rescue or extraction call as well as when preforming fire exposure protection. In the case of exposure protection the shield works better for it keeps more heat from the firefighters face, but the goggles give more eye protection in extraction and rescue ops.
EN 443:1997 (Helmets for firefighters) specifies the properties that are demanded for protection, comfort and durability. There are optional specifications to cater for national requirements.
Work gloves are a must for all fire departments. They are used when gloves are required, but actual firefighting gloves are not. They allow better mobility to perform various types of functions from relaying hose beds to vehicle maintenance. Work gloves are usually made of leather or a leatherlike material.
Extrication gloves are similar in design and appearance to auto mechanic's gloves but are made of a heavier rip-proof and puncture-resistant material such as Kevlar while still lightweight enough to allow the manual dexterity to operate rescue equipment and sometimes enough to take a victim's pulse. These are used in urban search and rescue, vehicle extrication and related applications, but are not rated for firefighting.
For an actual working fire, structural firefighting gloves must be worn. Structural gloves tend to be the last piece of protective equipment to be donned; usually because the free dexterity of the fingers are required to perform functions such as properly placing an SCBA mask on and accurately tightening a helmet strap. The gloves will fit over the wristlets and under the distal part of the coat sleeve, ensuring full enclosure of the latter arm. Gloves are designed to protect from extreme heat, various penetrating objects, and to allow dexterity. Usually the latter is sacrificed in order to give adequate protection to heat and sharp objects. Newer gloves are more lightweight and don't lose their dexterity when they dry after becoming wet such as leather gloves do.
Proximity gear or a fire proximity suit is turnout gear with an outer layer of heat-reflecting metallic material, used in firefighting applications of extreme heat such as aircraft fires and some chemical fires.
