Question 16Safety & Environmental - Assistant Engineer

The correct answer is A) secure all sources of fresh air to the tank. The reasoning is that in a fuel tank fire, the first priority is to cut off the supply of oxygen to the fire. Securing all sources of fresh air to the tank, such as vents and openings, will starve the fire of the oxygen it needs to continue burning. This is the most critical and effective first step in fighting a fuel tank fire. The other options are not the optimal first response. Transferring fuel to other tanks (B) could potentially spread the fire. Stationing someone at the CO2 release controls (C) is a secondary step after securing the air supply. Topping off the tank (D) could actually increase the risk of explosion by forcing out vapors.
