Firefighting Fundamentals Question And
Verified Answer
Flash point - Answer -✔✔the minimum temperature at which a flammable substance
gives off vapors that burn when a flame or spark is applied.
Fire Point - Answer -✔✔The temperature at which a fuel continue to burn after it has
been ignited. The fire point is usually a few degrees higher than the flash point
Spontaneous Combustion - Answer -✔✔With certain types of materials, slow oxidation
can turn into fast oxidation if heat is not dissipated, and results in a fire. For more info
refer to spontaneous combustion conditions.
Auto-Ignition/ Self- Ignition Point - Answer -✔✔The auto-ignition or self- ignition pt is the
lowest temp at which a substance must be heated to give off vapors that burn w/out the
application of spark or flame.
Water extinguisher - Answer -✔✔Absorbs enough heat to raise temp to 212° water
vapor temp. Steam carries away heat cooling surface temp.
Water Extinguisher - Answer -✔✔Class A & D Fires
CO2 Extinguisher - Answer -✔✔Displaces oxygen. Settles and blankets fire
CO2 Extinguisher - Answer -✔✔Class A&C Fires
Aqueous Film Forming Foam (AFFF) - Answer -✔✔Cools fire and coats fuel, preventing
contact w/ oxygen. Quickly spread over surface.
(AFFF) - Answer -✔✔CLass A&B Fires
Potassium bicarbonate - Answer -✔✔Extinguishes fire by separating the 4 parts of the
fire. Prevents chemical reactions halts production of 🔥.
Potassium bicarbonate - Answer -✔✔Class A&B Fires
Fire Tetrahedron - Answer -✔✔Heat, Fuel, Oxygen, Chemical Chain Reaction
Halon 1301/ HFP FM200/HFP - Answer -✔✔Works by mainly interrupting the reaction
of the fire tetrahedron. / Removes oxygen from space.
Halon 1301/ HFP FM200/ HFP - Answer -✔✔Class B Fires
, Aqueous Potassium Carbonate (APC) System - Answer -✔✔Generates a soap like froth
that excludes air from surface of grease/ oil.
Aqueous Potassium Carbonate - Answer -✔✔Class B Fires
Water Mist - Answer -✔✔Discharges high-pressure fresh water. That knocks down open
flame to a smoldering state, preventing fire from spreading.
Water Mist - Answer -✔✔Class A Fires
Lithium (special hazard) - Answer -✔✔Class D
Highly reactive combustible
Jettison overboard & then combat fire w/ H2o.
Magnesium (special hazard) - Answer -✔✔Class D
Combustible
Jettison combat fire w/H2o
Deep Fat Fryer (special hazard) - Answer -✔✔Class B
Multiple Factors that contribute to increased intensity and spreading of fire
Aqueous Potassium Carbonate
Isolation Impor (Electrical power) - Answer -✔✔Usually root cause of fire. Potential to
feed the intensity of fire.
Isolation Impor ( Mechanical Systems) - Answer -✔✔Potential to feed/ contribute to fire
intensity
Boundary Area Cooling Methods - Answer -✔✔Charged hoses: Cools fire boundaries
between safe boundaries and fire
Boundary area cooling methods - Answer -✔✔Sprinkler system: Prevents spread of fire
boundary space & assist/ eliminate need 4 boundary men
Boundary area cooling methods - Answer -✔✔Water Application: Provides small
amounts of water to cool bulkheads & decks. Cooling achieved & prevents rapid build
up of steam.
Procedures 4 Reporting Casualties - Answer -✔✔1). Cas/ Fire
2). Location
3). Compartment #
4). Name Off of Deck
5). Conduct initial actions
