Block 6 - Firefighting Fundamentals Flashcards
What is the primary duty of the fire fighter?
Saving lives
What is the secondary responsibility of the fire fighter?
Extinguish fires and limit the damage to aircraft
What is a simple model that includes heat, fuel, and oxygen as the key components?
Fire triangle
What are the key elements of the fire tetrahedron?
Heat
Fuel
oxygen
chemical chain reaction
What a that fire occurs in combustible materials that produce an ash, such as burning wood and wood products, cloth, textile and fibrous materials, and paper products?
Class Alpha fires
What are effective extinguishing agents for class alpha fires?
Water (H20
aqueous film forming phone (AFFF)
What class of fire occurs with flammable liquid Substances such as gasoline, jet fuel’s, oil, and other petroleum based products?
Class bravo fires
What are the effective extinguishing agents for class bravo fires?
AFFF
Halon 1211
purple K powder (PKP)
carbon dioxide (CO2)
What are energized electrical fires that are attacked by using non-conductive agents?
Class Charlie fires
What are effective extinguishing agents for energize class Charlie fires?
CO2
Halon
PKP
H2O in fog patterns with minimum distance of 4 feet
What class fires involves combustible metals such as magnesium and titanium?
Class Delta fires
What are the effective extinguishing agents for class delta fires?
H20 in large quantities in the high velocity fog
Apply water from a safe distance or from behind shelter as small explosions can occur
What fire fighting agent consist primarily of synthetic fluorocarbon surfactant Materials that are non-corrosive and have an unlimited shelf life when stored in a protected area?
Aqueous film forming foam (AFF) liquid concentrates
Water is also an effective agent for cooling ordinance, batteries in which class of fire?
Class alpha fires
Which fire fighting agent is intended primarily for use in class B and C fires, however it is a factor of a class A fires?
Halon 1211 (Bromichlorodifluoromethane)
What is a colorless, faint sweet smelling, electrically non-conductive gas that leaves no residue to clean up?
Halon 1211
What AFFF Concentration is approved for naval use?
3% and 6% AFFF concentrate
Current shipboard equipment requires which AFFF concentration
6% AFFF concentrate
What 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?
Water
What has the ability, when properly apply, to Cool the aircraft fuselage and provide a heat shield for personnel?
Water
What extinguishes fire by inhibiting the chemical chain reaction of the combustion process?
Halon 1211
What units are intended primarily for use on Class B and C Fires?
CO2 15 lb portable units
50 lb wheeled extinguisher units
This is a colorless, odorless gas that is approximately one and one-half times heavier than air?
CO2
What firefighting agent is intended primarily for use on Class B fires?
Potassium bicarbonate (purple – K powder or PKP)
What does not have cooling capabilities, therefore it will not result in permanent extinguishing (reflash protection) if ignition sources are present?
PKP
