Safety, Fire & Survival · Fire — Fixed CO2 System

- BIncrease the fuel supply
- CStart the bilge pump
- DAccount for all personnel, evacuate, and shut down ventilation and close openings✓ Correct
Explanation
CO2 flooding will asphyxiate anyone in the space, so all personnel must be evacuated and accounted for; ventilation is stopped and the space sealed (boundaries closed) before discharge so the CO2 concentration is achieved and held. An audible alarm precedes release.
