Fire Extinguisher Emergency Equipment on Airplane

Emergency Equipment On Airplane – In order to effect a safe and expeditious evacuation of the aeroplane and the necessary functions to be performed in an emergency.

The number of cabin attendants required for each type of aeroplane will be based on seating capacity of the number of passengers carried in accordance with the table below:

Number of Passengers
Number of cabin Attendants
1 – 50At least 1
51-100At least 2
101-150At least 3
151-200At least 4
201-250, etcAt least 5, etc

Fire Extinguisher Emergency Equipment on Airplane

1. H2O water fire extinguisher [color : gray or blue]

The waters F.E may be used to flight “Class A fire” mostly cabin fires in the waste containers. Duration: 30-45 Seconds. This type of fire extinguisher is not suitable:

  • On bumping liquids such as fuel, oil, grease, etc. Inflammable liquids are lighter than water will start floating on water, spreading out the fire
  • On electrical fires, pantry or cockpit fires. When sprayer on electrical fires, the danger of electrocution exist.

2. CO2 Fire Extinguisher [Color : Red with black horn]

The CO2 turns to clod snow [79° celcius] when leaving the discharge horn. Duration : 20 seconds

The snow lowers the temperature and shocks the fire by cutting off the air supply to the fire. This type of fire extinguisher is especially suitable to fight ‘inflammable liquid’ and ‘electrical fire’

3. BCF [Bromo chlouro di Flouro methane] fire extinguisher [color : Yellow with black horn]

This F.E is filled with BCF which is non-poisonous agent. The nozzles discharge BCF gas at 70 psi and snuffs out the fire at 50 mph.

BCF does not cause cold burns or harm fabrics, metals or other materials it may contact. This FE is suitable to fight class B and class C fires. It will also deal very effective with small class a fires.

4. Powder [dry chemical]

The extinguisher consist of a potassium bicarbonate, based charge dry chemical cylinder a discharge nozzle, pressure indicator, operating and holding handle. It is provided for the main Cabin for use against live electrical and inflammable liquid fires.

5. Halon Fire Extinguisher [color : red with black handle and discharge nozzle] use on all classes of fire.

The concentrated agent, or the by-products created by the heat of the fire, are toxic when inhaled.

The extinguisher is not recommended for use in confines spaces. However should it be used in such an area, and after the fire is out, ventilate immediately.

Class of Fires
Extinguisher Type
Class A: Combustable Materials

Paper, wood, fabric, rubber, certain plastic etc. where quenching by water is effective

Type A

  1. Water [H20]
  2. Saturates material, and
  3. Prevent rekindling
Class B : Inflammable Liquids

Gasoline, oils, grease, solvent, paints, burning liquids, cooking dats, etc where smothering action is required

Type B

  1. Carbon dioxide [CO2]
  2. BCF
  3. Dry Chemical
Class C : Live Electrical

Fire started by short circuit or faulty wiring in electrical, electronic equipment, or fires in motors, switches, galley equipment, etc where a non conducting extinguisher agent is required

Type C

  1. Carbon Dioxide [CO2]
  2. BCF
  3. Dry Chemical

List of Emergency Equipment On An Aircraft

Using the wrong extinguisher may do more harm than good, for example: B&C rated extinguisher is not as effective as H2O on a class A fire.

Water on inflammable liquid fires spread the fire. Water on a live electrical fire cloud cause severe shock or death.

Oxygen Systems

Supplementary oxygen systems are provided to allow unpressurized flight above 10.000 feet. For medical reasons, and to provide oxygen in the event of failure of the aircraft’s pressurization system.

Pressurized aircraft are often fired with an auto-deployment oxygen available to the mask, should the cabin altitude become excessive. The pressure to the mask automatically releases the dispenser doors and allows the masks to fall out.

Cabin pressurization is maintained at an altitude of 5.000-7.000 feed for the comfort and safety of passengers and crew members.

A decompression occurs when cabin pressurization is lost. The primary danger resulting from decompression is ‘hypoxia’ [lack of adequate oxygen to the body tissue]. If a victim of hypoxia does not get oxygen quickly, unconsciousness will follow.

After 4-6 minutes without oxygen, he/she will suffer serious brain damage or may be death, so the oxygen must be supplied immediately.

Without supplemental oxygen, time of useful consciousness after a decompression is:

Cabin Altitude
Time of Consciousness
40.000 feet18 Seconds
35.000 feet30 seconds
30.000 feet45 seconds
28.000 feet1 minutes
25.000 feet2 minutes
22.000 feet5 minutes

The emergency cabin oxygen system is designed to supply oxygen to all occupants while the aircraft is descending to a safe altitude following a decompression.

A rapid decompression is a sudden loss of cabin pressure which may be caused by an explosion, a rupture in the fuselage or a malfunction of the pressurization system.

Immediately following a decompression, the cockpit crew will initiate a sleep spiral descent to a safe altitude [10.000 feet or below]

Causes of Fires

Cargo Compartment fire Classifications:

1. Class A

  • Located in forward & aftward of the cabin
  • Accessible in flight
  • No cargo doors is/are equipped
  • Hand held fire extinguisher available in cabin
  • Provide visual detection of smoke

2. Class B

  • Located in cabin [Usually in afterward of the cabin]
  • Accessible in flight
  • Cargo door is equipped
  • Hand held fire extinguisher available in cabin
  • Cargo compartment is equipped with a separate system of an approved type smoke detector or fire detector to give warning to the cockpit

3. Class C

  • Located in the lower cargo [below the cabin floor]
  • Cargo doors are equipped
  • Cargo compartments are equipped with smoke detectors and built in fire extinguisher, controlled from the cockpit

4. Class D

  • Located in the lower cargo [below the cabin floor]
  • Cargo doors are equipped
  • Cargo compartment which designed and constructed that a fire occurring there in, will be completely confined without endangering the safety of the aircraft or occupants [fire proofed cargo compartment]

The Age of Jet

Almost all aircraft accidents happen when the plane is taking off or landing. The plane is going at high speed, it is close to the ground and the pilot has to think of many things. Darkness and weather also tend to concern the pilot during take-off and landing.

Aircraft today are bigger and faster. Usually passengers are not worried. The design of aircraft today I very good and the engines are very reliable. Also the pilots are well trained and there are many electronic devices on the plane.

Helicopters can take off and land vertically. They have rotating wing, which lifts the aircraft. But helicopters can not fly as fast as fixed-wing aircraft.

There have been many aircraft build with VTOL [Vertical take-off and landing] ability. The most famous is the Hawker Siddeley Harrier.

This is a fighter plane and has the performance of and ordinary jet fighter and the take off and landing ability of a helicopter.

Why do we need the jet engine? Only the engine can meet the needs of our modern world. The jet engine is much faster than other types of engine.

Two speeds are best for transport aircraft. The first is subsonic, below Mac 0,8 to 0,9. Above this speed, drag can become a problem. The second is supersonic speed.

Above this speed, drag can become a problem. The second is supersonic speed. Mac 2.0 and above. The economy of flying at this speed is greater than the effect of drag on the aircraft.

Air traffic around the world is growing, so it is cheaper to use one large plane instead of two small ones. Aircraft manufactures are designing bigger and faster planes.

The weather

Today, meteorologist send rockets and balloons up into the atmosphere to study it and also to get samples. They put satellites up in the rockets and these satellites orbit the earth and send back information.

There are many satellites up in space which are at different heights. The information they send back is studied with the help of powerful computers.

With all this information, meteorologist hope that they can predict tomorrow’s weather. We often se this on television, it is called the weather forecast. These forces affect the weather, and of course, the weather affects you and me!

We can see many benefits from the study of meteorology. The reports from these meteorologists can save people’s live. When you become a pilot, you will use them to let you know the type of weather you will be flying through.
