• What is the primary purpose of a pre-incident plan in firefighting

operations?

• To schedule crew shifts
• To identify potential fire hazards and resources
• To replace standard operating procedures
• To train new recruits
• To identify potential fire hazards and resources

Rationale: Pre-incident plans allow responders to anticipate hazards,

plan resources, and implement strategies before a fire occurs. 1 / 4

• What type of fire involves flammable liquids such as gasoline or oil?
• Class A
• Class B
• Class C
• Class D
• Class B

Rationale: Class B fires involve flammable liquids and gases,

requiring foam, dry chemical, or CO2 extinguishing agents.

• Which fire suppression method is most effective for Class A fires?
• Smothering with foam
• Cooling with water
• Using CO2
• Sand application
• Cooling with water

Rationale: Class A fires involve ordinary combustibles like wood or

paper, where water effectively absorbs heat to extinguish the fire.

• During a shipboard fire, what is the primary concern when using water

on electrical equipment?

• Equipment damage
• Water pollution
• Electrical shock hazard
• Overcooling the fire area
• Electrical shock hazard 2 / 4

Rationale: Water conducts electricity; using it on energized

equipment poses a severe risk of shock or electrocution.

• Which type of portable extinguisher is suitable for electrical fires?
• Water
• Foam
• CO2
• Wet chemical
• CO2

Rationale: Carbon dioxide extinguishers displace oxygen without

conducting electricity, making them safe for electrical fires.

• What is the first action when a fire is discovered on a vessel?
• Investigate the fire alone
• Sound the general alarm
• Attempt to extinguish the fire immediately
• Evacuate the vessel
• Sound the general alarm

Rationale: Alerting the crew ensures coordinated action and safety

before fire suppression begins.

• What is the recommended position when advancing a charged hose

line into a fire?

• Upright with back to the fire
• Kneeling or low stance toward the fire
• Sitting on the floor 3 / 4

• Standing behind the fire
• Kneeling or low stance toward the fire

Rationale: A low stance reduces heat exposure and improves stability

when advancing hose lines.

• Which extinguishing agent works by separating fuel from oxygen?
• Water
• Foam
• CO2
• Dry chemical
• Foam

Rationale: Foam forms a blanket over flammable liquids, preventing

oxygen from fueling the fire.

• What is the primary hazard of smoke inhalation during firefighting?
• Heat exposure
• Oxygen displacement and toxic gas inhalation
• Reduced visibility
• Equipment damage
• Oxygen displacement and toxic gas inhalation

Rationale: Smoke contains carbon monoxide, cyanide, and other

toxic gases that impair breathing and can be fatal.

• What is the key advantage of using a self-contained breathing

apparatus (SCBA)?

• Increased mobility
