You have just extinguished an oil fire on the floor plates of the engine room with a 15 pound CO2 extinguisher. Which of the listed dangers should you now be preparing to handle?

Correct Answer: Option A — Reflashing of the fire.

CO2 is an inert gas that smothers fire by displacing oxygen. However, it does not provide significant cooling. If the fuel source remains hot, the reintroduction of oxygen upon ventilation can cause the oil to re-ignite. Always maintain a fire watch and monitor the area for heat until the surface temperature drops.
