For a liquid propane gas truck involved in fire, which type of fire stream is recommended?

• A. Use two handlines with wide fog while advancing.
• B. Use one handline from an aerial position.
• C. Place unmanned monitors with smooth bore nozzles.
• D. Advance two handlines with wide fog while advancing.

Answer: (C)

When a liquid propane gas truck is on fire, the priority is to cool the tank from a safe distance to prevent a BLEVE and reduce vapor release. The best approach is to use unmanned monitors with smooth bore nozzles. A fixed, high-volume water stream delivered from a monitor keeps firefighters well back from the hazard while providing ample cooling to the tank surface and surrounding area. The smooth bore nozzle concentrates the water into a solid jet that can reach and blanket the critical areas, maximizing heat absorption and reducing the chance of the tank rupturing. Other approaches that require closer proximity or use a fog pattern can spread flammable vapors or deliver less effective cooling, increasing risk. An aerial handline may offer reach but still exposes operators and often cannot deliver the same cooling capacity as a large, unmanned monitor. In short, remote cooling with unmanned monitors and smooth bore nozzles offers the safest stance and strongest cooling for LPG tank fires.
