P-3 Eaws (Fire Fundamentals)

What is the fire triangle?

Back 1

It is a simple model that includes heat, fuel, and oxygen as the
key components.

Front 2

P-3 EAWS (Fire Fighting)

What partially replaced the fire triangle and why?

Back 2

The fire tetrahedron, because of a fourth critical
element which is the chemical chain reaction that takes place in a fire and allows the fire to both sustain itself and grow. The addition of a fourth element is what makes the triangle become a tetrahedron.

What happens when you remove one of the elements of the fire triangle or tetrahedron?

Back 3

The removal of any one
of the elements prevents or extinguishes a fire.

Front 4

P-3 EAWS (Fire Fighting)

How many classes are fires divided into?

Back 4

Four Classes, Alpha, Bravo, Charlie, and Delta.

P-3 EAWS (Fire Fighting)

What is an Class Alpha Fire and what are the extinguishing agents?

Back 5

Occur in combustibles materials that produce an ash such as burning wood and wood products, cloth, textiles and fibrous materials, and paper products. Effective extinguishing agents are water (H2O) or Aqueous Film Forming Foam (AFFF).

Front 6

P-3 EAWS (Fire Fighting)

What is an Class Bravo Fire and what are the extinguishing agents?

Back 6

Occur with flammable liduid substances such as gasoline, jet fuels, oil, and other petroleum based products. Effective extinguishing agents are AFFF, Halon 1211, Purple K Powder (PKP) and Carbon Dioxide (CO2).

Front 7

P-3 EAWS (Fire Fighting)

What is an Class Charlie Fire and what are the extinguishing agents?

Back 7

Are energized electrical fires that are attacked by using non-conductive agents. Effective extinguishing agents are:
- Energized. CO2, Halon, PKP, and H2O in fog patterns with a minimum distance of 4 feet.
- De-energized. Treat as a Class A, B, or D fire.

P-3 EAWS (Fire Fighting)

What is an Class Delta Fire and what are the extinguishing agents?

Back 8

Combustible metals such as magnesium and titanium. Effective extinguishing agents are H2O in large quantities in high velocity fog, apply water from a safe distance or from behind shelter as small explosions can occur.

What is AFFF and explain it's uses?

Back 9

Aqueous Film Forming Foam (AFFF) liquid concentrates consist primarily of synthetic fluorocarbon surfactant materials that are noncorrosive and have an unlimited shelf life when stored in a protected area. Three-percent and six-percent AFFF concentrate is approved for naval use. Current shipboard equipment requires six-percent concentrate.

What is Water(H2O) used for in fire fighting?

Back 10

Water is not generally considered to be a suitable agent for use in combating large aircraft fuel fires without the addition of either foam agents or surfactants. It has the ability, when properly applied, to cool the aircraft fuselage and provide a heat shield for personnel. Water is also an effective agent for cooling ordnance, batteries, and Class A fires.

Front 11

P-3 EAWS (Fire Fighting)

What is Halon 1211 and explain it's uses?

Back 11

Intended primarily for use on Class B and C fires; however it is effective on Class A fires. Halon 1211 is a colorless, faintly sweet smelling, electrically nonconductive gas that leaves no residue to clean up. Halon 1211 extinguishes fires by inhibiting the chemical chain reaction of the combustion process.

Name the 2 types of Fire Extinghishers and explain their uses?

Back 12

Carbon Dioxide 15-Pound Portable Units and 50-Pound Wheeled Extinguisher Units. These units are intended primarily for use on Class B and C fires. CO2 is a colorless, odorless gas that is approximately one and one-half times heavier than air. Fire suppression is accomplished by the displacement of oxygen to below the level that is required to support combustion.

Front 13

P-3 EAWS (Fire Fighting)

What is PKP and explain it's uses?

Back 13

Potassium Bicarbonate (Purple-K-Powder or PKP). PKP is intended primarily for use on Class B fires. The principal chemical in PKP is potassium bicarbonate and the dry chemical extinguishes the flame by breaking the combustion chain. It does not have cooling capabilities, therefore it will not result in permanent extinguishing (reflash protection) if ignition sources are present.
