engine white Q2.

Q6. Water mist systems suppress fires by:

a) Creating a foam blanket
b) Cooling and displacing oxygen with fine droplets
c) Electrically shocking the fire
d) Releasing nitrogen gas

Q7. Foam sprinkler systems are particularly effective against:

a) Electrical panel fires
b) Hydrocarbon fuel fires
c) Wood and paper fires
d) Bilge water fires

Q8. Inert Gas (IG) systems are safer for crew because:

b) Class B fires only
c) Electrical fires
d) Class C gas fires

Q12. Which extinguisher is most appropriate for an electrical panel fire?

a) Foam
b) CO₂
c) Water
d) Dry powder

Q13. The main source of water for hydrants in the engine room is:

a) Freshwater tanks
b) Seawater via fire pumps
c) CO₂ cylinders
d) Bilge pumps

Q14. What is the function of hydrant valves?

a) Release CO₂ into pipes
b) Control the flow of seawater to hoses
c) Detect leaks in pipes
d) Regulate foam mixing

Q15. Hose reels are designed to:

a) Store fire extinguishers
b) Unspool hoses quickly during a fire emergency
c) Supply fuel to pumps
d) Drain bilge water

Q16. Before activating a CO₂ flooding system, what must be ensured?

b) Crew have evacuated the engine room
c) Foam sprinklers are turned on
d) Exhaust fans are off

Q17. Monthly checks for fire systems include:

a) Fuel tank calibration
b) Testing solenoid release valves and pump pressures
c) Changing extinguisher colors
d) Draining the bilge

Q18. Extinguisher gauges should be:

a) Always in the red zone
b) Checked only after use
c) In the green zone for readiness
d) Ignored unless fire occurs

Q19. Crew fire drills in the engine room typically start with:

a) Resetting the fire panel
b) Charging hoses immediately
c) Alarm activation and evacuation
d) Inspecting extinguishers

Q20. Why should detection and suppression piping be clearly labeled?

a) To reduce corrosion
b) To avoid confusion during emergencies
c) To meet paint requirements
d) To improve water pressure
