Fire Prevention and Fire Fighting Flashcards

What are the three elements of the fire triangle?

Answer: Fuel, heat, and oxygen

The fire triangle consists of fuel (combustible material), heat (ignition source), and oxygen; removing any one element will extinguish the fire.

What class of fire involves flammable liquids such as oil, gasoline, and paint?

Answer: Class B

Class B fires involve flammable liquids and gases such as oil, gasoline, diesel fuel, and paints, which are common hazards aboard vessels.

Which type of fire extinguisher is most appropriate for a Class C (electrical) fire?

Answer: Dry chemical or CO2 extinguisher

CO2 and dry chemical extinguishers are non-conductive and safe for Class C electrical fires; water and foam conduct electricity and can electrocute the operator.

What is the purpose of a fire detection system aboard a vessel?

Answer: To provide early warning so the crew can respond before a fire spreads

Fire detection systems provide early warning through heat, smoke, or flame detectors, allowing the crew to respond quickly before a fire grows to an uncontrollable size.

When fighting a fire in an enclosed space, what is the primary personal safety concern?

Answer: Oxygen depletion and toxic smoke inhalation

Enclosed spaces rapidly become oxygen-deficient and fill with toxic gases during a fire; firefighters must wear self-contained breathing apparatus (SCBA) to survive.

What is the first action a crew member should take upon discovering a fire aboard?

Answer: Sound the alarm to alert the crew and master

The first action upon discovering a fire is to sound the alarm to alert the entire crew, enabling a coordinated response and ensuring safety of all persons aboard.
