You have found a fire, reported it, and are leaving the area, what should you do with the doors as you leave the space?

Correct Answer: Option B — Close them securely

Closing doors securely is a fundamental fire-containment tactic. It limits the oxygen supply to the fire, preventing rapid growth and slowing the spread of smoke and heat to adjacent compartments. This action is essential for maintaining the integrity of fire boundaries and protecting the rest of the vessel.
