An oil fire is reported in the purifier room bilge. How would you combat this fire?

Correct Answer: Option A — Direct aqueous film forming foam off the overhead or nearby bulkhead, using a bank down or bounce off method to extinguish the fire.

AFFF is highly effective for fuel fires. By bouncing the stream off a bulkhead or overhead, the foam forms a blanket over the fuel surface without agitating the liquid, preventing the fire from spreading and effectively cutting off the oxygen supply to the burning oil.
