WARNING

A hazardous condition exists regardless of the method used to open and remove the canopies. It is imperative that ballistics lines to ejection seat catapults be severed immediately upon gaining access to the cockpits.

Once access to the cockpits is possible, rescue personnel can begin immediately with flight crew removal porcedures. (See, Sheet

Damage Prevention.

The following Information conaiata of data and recommended procedure* for the extinguishing of aircraft firea.

Fire and Explosion Hazard*.

Personnel ahould be familiar with the fire and exploatoa hazard* of thia aircraft ao that precautionary meaaurei can be taken. Flrea and exploeion* generally occurlammable substance, osygen (air)ource of ignition are brought together. The primary flammable sub-stances in this aircraft are fuel, hydraulic fluid, lubricating oil and greases and pyrophoric fluid used In the engine ignition system. Pure oxygen canire or explosion simply by contact with these substances. Common source of ignition are electric arcs, flame add hot surfaces, The following conditions are particulary hazardous:

a. The mixture of fuel vapor and air in the fuel tanks snd vert system is explosive *sien Igntied. However,lass fuels are not as critical as other type jet fuel also the aircraft tank* are in-ertedlanket

pyrophoric fluid (triethylborane) used in the enginewill ignite immediately upon exposure to air.

Fir* Fighting Precautions.

Personnel should be alert for possible aire raft ground fires and be prepared to act rapidly and effectivelyire is discovered. It Is recommended that all personnel become familiar with the following types of fire hazards and precautions.

to notify professional fire fighting personnel immediately.

c- The agents that are recommended for different kinds of fires and how to operate extinguishing equipment eg, area water, water fog,CP or chemical and mechanical foams.

d. Chemical and mechanical foam agents leavef possible these agents should be remoVed by flushing with water.

> CAUTION Annul Plusry Chemical Powder should not be used except la an emergency. If used, all traces of residue shall be completely removed by spraying with JP5 Class Fuel, flushing thoroughly

Oxygen Fires.

Oxygen can cause spontaneous ignition and explosions when it comes in contact with flammable subetancea. Flrea aided by oxygen will burn intenaly and apread rapidly, therefore, .CO? or DCP (dry chemical powder) should be applied to alow the progress of these flrae. However.effective extinguishing of oxygen-supplied ftrea generally require foam. Sourceser cent oxygen in the aircraft are the battle* or containers located la the nose wheel compartment area.

Engine or nacelle (ires may not be indicated by the engine fire and/or overheat system. Personnel should be alert for this condition at all timosengine ground operation.

Chemical Ignition Fuel (TEB) Fires.

lrewill occur when triethylborane (TEB) is exposed to airesult of line rupture or leaks. ToEB fire, the fire fighter should attempt to confine the fire by blanketing the burning liquid with foam, water spray or co2.

W ARN1NG

Carbon tetrochlorlde and halogenated hydrocarbons react with TEB and should never be used to combat flree.

Note

Tests have indicated that TEB will Ignite when exposed

to air at all temperatures to be encountered during hanldlng.

Wheel Brake Fires. (See. )

WARNING

Exceeaive brake heating tends to weaken tire and wheel structure and increase tire pressure. The area inboard and outboard of the wheel should be avoided.

a. Apply DCP, water or water fog to brake and wheel.

ealth Liquid Nitrogen.

Liquid nitrogen is contained in two flasks located within the nose landing gear compartment. Contact with thie liquid shall be avoided aa direct akin contact can reeult in extremely painful aorea, which resemble burns. Alao, symptoms of hypoxia can occur from prolonged contact with eacaping GN2 in confined areas.

Ammonia.

Ammonia gas is poisonous in strong concentrations, and can cause severe damage to the tissues of the eyes, nose, throat and lung*. Aqua ammonia solution is very caustic, and can be damaging to the skin tissue if not waahed off immediately after contact.

qua ammonia solution is containedompartment located on the right lower fuselage section just forward of the wing leading edge.

Triethylborane (TEB).

TEB will cause serious thermal burns upon akin contact. The burned area may provide highly absorbent area for this compound. akin contact must be avoided. Inhalation of these compounds isunlikely due to the pyrophoric characteristics. However, the fumes are toxic. Two TEB tanks, one for each engine,c of fluid each when initially serviced. (Seeor tank location. )

Should personnel contact be made witheurce ofclean water must be uaed to flush burning fuelerson. contamination of the burned area if at all poaaible. If TEB contacts the eyes, flush immediately with large quantities of water foroinutes or until medical personnel arrive.

CAUTION

Do not attempt to support aircraft for tooime. Bags do not have adequate pressure-holding qualities to permit them to be used as permanent supports.

b. When aircraft is adequately supported, remove bags, pads, tar-pulins and mooring ropes.

Extension of Landing Gear. (See. )

Once the aircraft has been raised to gear extension height plus approximately six Inches above terrain, the following procedures shall be followed to extend the landing gear:

CAUTION

Ensure that the main and noae landing gear doors are clear.
