As Chief Engineer, how would you instruct a new Third Assistant Engineer to use the fire fighting apparatus illustrated to fight an oil fire at the bunker station? Illustration SF-0020

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

Applying AFFF directly onto a Class B liquid fuel fire risks splashing burning fuel. The correct technique deflects the foam stream off an overhead or bulkhead, allowing it to gently blanket the fuel surface and form an aqueous film that smothers vapors.
