After extinguishing a paint locker fire using the fixed CO2 system, the next action is to have the space _______________.
AI Explanation
The correct answer is B) remain closed with vents off until all boundaries are cool.
When a fire is extinguished in a confined space like a paint locker using a fixed CO2 system, it is important to keep the space sealed and the vents closed until the boundaries (walls, ceiling, etc.) have cooled completely. This allows the space to remain oxygen-deprived, preventing a potential reflash of the fire. Opening the space or introducing water too soon could reignite the fire. Checking the oxygen content is also important, but should be done after the space has cooled, not immediately after extinguishing the fire. Removing the burned material can wait until the space is fully secured and cooled.
