STCW Basic Fire Fighting ACTUAL
Questions and CORRECT Answers
Fire Triangle - CORRECT ANSWER - Oxygen, Heat, Fuel
Types of Fuel and Combustion:
Liquid Fuels - CORRECT ANSWER - Vaporization - is the release of liquid's molecules
into the atmosphere, when vapors reach the *Flashpoint they ignite
Types of Fuel and Combustion:
Volatility - CORRECT ANSWER - - Indicates the ability of a liquid to liberate into a gas
- The lower the boiling point, the more volatile
Types of Fuel and Combustion:
Flame Point - CORRECT ANSWER - The lowest temperature at which the liquid emits
adequate gas to ignite with a flame.
(May be a light flicker because the liquid does not emit enough gas to keep the fire alive)
Types of Fuel and Combustion:
Combustive point - CORRECT ANSWER - The temperature where the liquid will emit so
much gas, that if ignited, it will continue to burn
Types of Fuel and Combustion:
, Self-Ignition Point - CORRECT ANSWER - The temperature at which the gas/air mixture
will start to burn by itself without being ignited by a flame or a spark
Categories of Combustion:
Spontaneous Ignition - CORRECT ANSWER - Occurs when a substance heats up and
ignites itself without any external heat source
Ex. fish flour, chemical substances, rags, waste from oil/paint and copra (coconut oil)
Categories of Combustion:
Inflammable Materials - CORRECT ANSWER - The material will ignite with a match and
continue to burn after ignition
Ex. paper, wood, textiles
Categories of Combustion:
Non-flammable Materials - CORRECT ANSWER - Need a large supply of heat before it
ignites and will extinguish itself if the external heat source is removed
Ex. Wool, plaster, certain plastic products
Backdraft - CORRECT ANSWER - A fire explosion when air is rapidly introduced to an
oxygen deficient space, increasing safety risk to fire fighters
Class A Fire - CORRECT ANSWER - - Ordinary Combustible Fires
- Ex. Wood, paper, plastic and everything that leaves behind ash when burned
- Primary extinguishing agent: water (cools fuel below ignition point) and dry chemicals
Class B Fire - CORRECT ANSWER - - Flammable Liquid fires
