Fire Proximity Suit:
A fire Proximity suit(also, silvers or silver bunker suit) is a suit designed to protect a fire fighter from high temperatures, especially near fires of extreme temperature such as aircraft fires.
Fire proximity suits first appeared during the 1930's, and were originally made of asbestos fabric(hence also known as the asbestos suit). Today, they are manufactured from vaccum deposited Aliminized material that reflect the high radiant loads produced by the fire. There are three basic types of these Aluminisied suits: Approach suited for work in the general area of high temperatures such as steel mills and smelting facilities. Proximity suited for aircraft rescue and fire fighting(AR-FF) and, in more heavily insulated versions, for work requiring entry into the heated area.
•Entry suited for entry into extreme heat and situations requiring protection from total flame engulfment.
•Complete proximity protection for AR-FF requires.
•Aluminized hood or helmet cover with neck shroud.
•Aluminized jacket and pants complete with vapour barrier insulated liner.
•Aluminized lined gloves.
•Aluiminized AR-FF boots.

Various types of Fire Proximity Suits:
Some of the fire proximity suits are described as follows:-
•Gas tight chemical protective suits:When working with or handling dangerous chemicals, human health can often be at serious risk from these hazardous substances. The quality and design if protective clothing intended for a particular purpose will depend among other things on whether the chemical in question is in solid, liquid or gaseous form.
•Splash suits: Splash protection clothing is needed whenever a person's skin requires protection from the harmful effects of liquid and solid hazardous substances. In some cases, it is enough to wear partial body protection. However, if there is any danger that the whole body could come in contact with solid or liquid chemicals, only a splash protection overall will provide optimum protection.
•Hazmat suit: This is a garment worn as protection from hazardous materials or substances. It is generally combined with breathing apparatus for protection and may be used by fire fighters, emergency personnel responding to toxic spills, researchers, specialists cleaning up contaminated facilities or workers in toxic environments.
•Gas/vapour protection suit:Such suits are gas or vapour-tight, providing total encapsulation and the highest level of protection against direct and airborne chemical contact. They are typically worn with a self-contained breathing apparatus (SCBA) enclosed within the suit. These suits are typically constructed of several layers and, being air tight, include a release valve so the suit does not over inflate from air exhaled by the SCBA. The release valve does retain some air to keep some positive pressure (overpressure) inside the suit. Such suits are usually limited to just 15-20 minutes of use by their mobile air supply.
With each suit described, there is a manufactured device designed to protect the respiratory system of the wearer while the suit/ensemble is used to protect skin exposed to potential or actual dermal, hazardous agents. That device is a respirator. A respirator may be something as simple as a headband strap filtering face piece respirator (FFR), to a head harness negative pressure full-face respirator, to a full face, tight fitting, closed breathing air, or open circuit, self-contained breathing apparatus (CC-SCBA or SCBA).

FIRE ENTRY SUIT.
Highly insulated fir entry suits are worn by personal in preparation for possible fire eruption in the immediate work area or for stand by operations, should a rescue or evasive action require passage
through a fire zone. Seven additional insulation layers provide maximum protection from heat and fire. Highly insulated boot sole provides protection from hot floors Complete set includes hood, coat, pants, boots, mitts and foot locker box for storage.
•Hood: Designed to be used with air mask. Inner drape flame seals. Underarm adjustment straps. Built-in shell for structural support. Hard cap with ratchet headgear. Speedy clip for hard cap support. Hardened aluminium window frame with two tempered glass lenses, plus two gold plated lenses for thermal protection.
•Coat:Designed to be worn with a breathing apparatus Double storm fly front. Flame seal with drawstring at coat bottom.
•Pants:High waist design. 2-inch wide adjustable suspenders. Adjustment straps on leg bottoms.
•Boots:Designed to fit over shoes. Rear entry with overlap snap closure and adjustable take-up straps. Insulated wire reinforced sole of flame resistant neoprene fiberglass riveted to boot cover.
~Thermal Imaging:
Thermal imaging detects and measures the thermal heat emitted by people and objects. It has a wide range of applications, some of which require protective gear and special techniques. A person who takes a thermal image is called a Thermographer. Medical thermal imaging, also called thermography, locates disease via body surface temperature. Thermal imaging is also used by fire fighters to see through smoke and find victims or pinpoint the source of the fire. It is used by engineers to inspect and locate over-heating in equipment and power lines, by rescue teams to locate missing individuals, by the military, law enforcement and security and even by those studying volcanoes and the stars. Some of the more common thermal imaging cameras are semiconductor-based sensors that use combinations of elements, such as Indium Antimonide or Indium Gallium arsenides to detect heat. This type if camera is often used in high-power, high frequency electronics. Another type of current thermal imaging camera uses mercury cadmium telluride to create a semiconductor- based sensor that is used by car drivers to see through dense fog. Quantum well infrared photo detectors are sensors used by astronomers to detect the heat signature of far distant stars.
•Who invented the fire suits?
Former Racer And Inventor Of The Nomex Fire Suit Bill Simpson Dies At 79.
•Standard time require by a fire fighter.
It should take upto 2mins for a fire fighter to wear the suit along with other gears.
