To create a safe haven when a liquid propane gas truck is involved in fire, firefighters should:

• A. Let the fire burn itself out.
• B. Off-load the tank.
• C. Advance hoselines from the sides of the tank.
• D. Advance two 1-3/4 inch handlines from both ends of the tank.

Answer: (C)

When propane is heated in a fire, the tank can fail violently if the heat isn’t controlled. The main goal is to prevent a BLEVE by cooling the tank so its temperature and internal pressure don’t spike. Applying water to the sides of the tank achieves this by covering a large surface area around the vessel, cooling the metal and slowing heat absorption from the fire. That cooling helps preserve the tank’s integrity, making it safer for firefighters to place themselves in a protective haven behind the tank as the fire is managed. Letting the fire burn or off-loading the tank expose you to extreme heat and potential spills or rupture, so those aren’t viable options. Attacking from the ends can focus water on fittings and may not cool the entire tank effectively, which is why cooling from the sides is the preferred tactic.
