Question 1

What are the three elements of the fire triangle?

Accepted Answer

Fuel, heat, and oxygen

Answer

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

Question 2

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

Accepted Answer

Class B

Answer

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

Question 3

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

Accepted Answer

Dry chemical or CO2 extinguisher

Answer

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.

Question 4

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

Accepted Answer

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

Answer

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.

Question 5

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

Accepted Answer

Oxygen depletion and toxic smoke inhalation

Answer

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