- AIncrease ventilation to the space
- BEnsure all personnel are out and the space is sealed (ventilation and openings closed)✓ Correct
- CAdd fuel to starve the fire faster
- DOpen the space to the weather
Explanation
Account for all personnel and evacuate the space, then secure ventilation, dampers, and openings so the CO2 concentration can build and hold. Releasing CO2 with someone still inside, or into an open space, is both lethal and ineffective.
