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

D) Turn off the fire alarm system

B) Ensure all personnel have evacuated the machinery space

C) Open all machinery space doors

A) Increase ventilation

2 / 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

C) To increase ventilation during high temperatures

A) To maintain constant air pressure

D) To cool machinery using CO₂

3 / 10

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

D) By an automatic time delay switch

A) By an automatic temperature sensor

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

C) By a smoke detector in each cylinder

4 / 10

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

B) Within 2 minutes

D) Within 15 minutes

A) Within 5 minutes

C) Within 10 minutes

5 / 10

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

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

C) To control the CO₂ release duration

6 / 10

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

C) Keep cylinders empty until needed

A) Discharge each cylinder annually

D) Replace all hoses every month

B) Test cylinder pressure and inspect for leaks periodically

7 / 10

What type of signage is required near CO₂ activation points?

A) "Ventilation Required"

D) "CO₂ Gas – Risk of Suffocation"

C) "Fire Extinguisher Inside"

B) "Do Not Enter During Discharge"

8 / 10

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

A) To increase pressure in the machinery room

B) To concentrate CO₂ in specific areas for rapid suppression

D) To control the temperature of the CO₂ gas

C) To filter the CO₂

9 / 10

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

A) Near the main engine

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

D) Outside the vessel

C) Directly in the machinery space

10 / 10

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

C) To increase CO₂ concentration

D) To allow fire alarms to activate after discharge

B) To provide time for personnel to evacuate before discharge

A) To allow time for system testing
