(1) TB 47- Aircraft Fire And Rescue

Question 1

Aircraft Crashes:

The CONTROL phase of aircraft firefighting involves the initial attack and establishment of rescue and/or escape areas, with full control of the situation established during the PRIMARY function, ______.

Answer 1

RESCUE

Question 2

Aircraft Crashes:

If no fire has occurred, all fuel as well as the aircraft engine should be covered with a _____ and the surrounding property protected with fog lines

Answer 2

Foam blanket

Question 3

Aircraft Crashes:

For a helicopter that has crash landed, if no other method is available, the engine can be shut down by discharging a _____ into the engine intake.

Answer 3

CO2 extinguisher

Question 4

In the “low impact” crash, RESCUE of occupants is the PRIMARY consideration.

In most high impact crashes, rescue is highly improbable. Fire control is principally sought to _________.

Answer 4

-protect exposed properties and to preserve evidence.

The high impact accident (hitting the ground or other objects) results in such structural breakup of the aircraft that survival of the occupants is highly unlikely (due to the impact trauma).

Question 5

No Fire Crashes

Particular attention should be given to any or all of the following points which may be important in the prevention of an outbreak of fire:

Answer 5

1. All engines not in use should be switched off. All exposed fuel blanketed with foam
2. Contain fuel
3. Stop leaking fuel by closing fuel valves or plugging ends of fuel lines
4. Avoid creating friction sparks
5. Do not interfere unnecessarily with aircraft
6. All forms of naked lights, flares, smoking etc., must be banned from area
7. disconnect aircraft electrical system

Question 6

Initial Attack

The best method for quick control of an area is ___________.

Answer 6

mass application of an extinguishing agent.

When water is limited, the use of fog nozzles or applicators with 1-1/2 inch hose lines is an acceptable approach. If additional water is available (by hydrants, etc.), the heavier 2-l/2 inch line and the deluge set with appropriate fog nozzles will provide wider coverage and more heat absorption for a more potent attack.
The use of AFFF should be an additional considertion.

Question 7

Initial Attack with water

Every effort must be made to maintain a wall of protection by overlapping the fog patterns and providing additional backup lines.

This is essential to avoid or reduce the probability of ______ so common to this type of operation.

Answer 7

reignition

Question 8

Initial Attack

The principal points of concern are:

Answer 8

the location of occupants trapped within the aircraft as well as normal and emergency entrances.

Question 9

Fuel

Special emphasis should be placed on reignition (flashback) while fighting a fire involving quantities of aviation fuels. An agent such as ______ should be used to completely cover the area

Answer 9

AFFF

Question 10

The primary objective during aircraft firefighting is the safe recovery of people involved in the incident. This objective is generally achieved in two stages:

Answer 10

1. Control of the fire
2. Rescue procedure

During the control phase, all effort must be directed to keeping the occupied portions of the aircraft cool by concentrating the extinguishing agents on those portions and the surrounding ground areas.

In no-fire incidents, the same basic procedures will be followed except that rather than fighting fire, the fuel spills must be blanketed or neutralized, and charged hose lines held ready in the event fire should break out.

Question 11

Establishing a rescue and escape “CORRIDOR” is the PRIMARY OBJECTIVE and determines the initial attack on the incident.

Selecting the area to provide this “corridor” will depend on:

Answer 11

-evacuation status of the occupants

-condition of the aircraft fuselage

-other factors such as wind direction
