Question 230Safety & Environmental - QMED

The correct answer is B) foam. Foam is an effective extinguishing agent for fighting large oil fires on the weather deck of a ship. Foam works by forming a blanket over the burning fuel, which cuts off the oxygen supply to the fire and cools the surface. This smothers the fire and prevents re-ignition. The other options are not as effective for this type of fire. High velocity fog (A) may not provide enough cooling and coverage to fully extinguish a large oil fire. Soda acid (C) and dry chemical (D) extinguishers are better suited for smaller, contained fires rather than a large deck fire. Overall, foam is the recommended extinguishing agent for effectively fighting a large oil fire on the weather deck of a ship.
