1 / 10

What is a critical safety step before discharging the CO₂ system in a machinery space?

D) Turn off the fire alarm system

C) Open all machinery space doors

B) Ensure all personnel have evacuated the machinery space

A) Increase ventilation

2 / 10

What is the function of CO₂ discharge nozzles in the system?

A) To increase pressure in the machinery room

C) To filter the CO₂

B) To concentrate CO₂ in specific areas for rapid suppression

D) To control the temperature of the CO₂ gas

3 / 10

Where should CO₂ cylinders be stored in a multiple bottle CO₂ system?

C) Directly in the machinery space

B) In a separate, well-ventilated room adjacent to the machinery space

A) Near the main engine

D) Outside the vessel

4 / 10

What is the primary purpose of a multiple bottle CO₂ gas system in a machinery space?

B) To rapidly reduce oxygen levels in the event of a fire, smothering flames

A) To maintain constant air pressure

D) To cool machinery using CO₂

C) To increase ventilation during high temperatures

5 / 10

What type of signage is required near CO₂ activation points?

A) "Ventilation Required"

B) "Do Not Enter During Discharge"

D) "CO₂ Gas – Risk of Suffocation"

C) "Fire Extinguisher Inside"

6 / 10

How is the multiple bottle CO₂ system typically activated in an emergency?

A) By an automatic temperature sensor

D) By an automatic time delay switch

B) By remote manual pull stations located outside the machinery space

C) By a smoke detector in each cylinder

7 / 10

What routine maintenance should be performed on a multiple bottle CO₂ system?

B) Test cylinder pressure and inspect for leaks periodically

C) Keep cylinders empty until needed

A) Discharge each cylinder annually

D) Replace all hoses every month

8 / 10

How quickly should the CO₂ system reach the necessary concentration in a machinery space?

C) Within 10 minutes

A) Within 5 minutes

D) Within 15 minutes

B) Within 2 minutes

9 / 10

Why is a time delay mechanism often incorporated in a CO₂ system for machinery spaces?

B) To provide time for personnel to evacuate before discharge

C) To increase CO₂ concentration

D) To allow fire alarms to activate after discharge

A) To allow time for system testing

10 / 10

Why does a multiple bottle CO₂ system use several CO₂ cylinders instead of a single large one?

C) To control the CO₂ release duration

D) To provide a redundant backup in case of individual cylinder failure

B) To distribute CO₂ evenly across different machinery zones

A) To allow for easy recharging
