A fixed CO2 fire suppression system in an engine room is classified as what type of system?
- ALocal application system
- BTotal flooding system✓ Correct
- CDeluge system
- DPre-action sprinkler system
Explanation
A total flooding system fills the entire protected space with extinguishing agent to achieve a uniform suppression concentration throughout the volume. CO2 engine room systems are total flooding — all openings must be closed and all personnel must evacuate before discharge. Local application systems direct agent at a specific hazard (e.g., a fryer hood) without flooding the entire space.
