Which configuration is recommended for remote water application to a LPG truck fire?

• A. Unmanned monitors with smooth bore nozzles.
• B. Two handlines with wide fog nozzles from the ground.
• C. One handline from an aerial position.
• D. A single handline with a fog nozzle.

Answer: (A)

Remote water application to an LPG truck fire works best when you keep personnel out of the heat and vapors while delivering a steady, controllable stream to absorb heat and suppress the fuel source. Unmanned monitors let water be applied from a safe distance with a fixed, elevated position, so crews aren’t near the vehicle while the fire is being knocked down. A smooth bore nozzle delivers a solid, coherent stream that reaches farther and provides strong impact on the fire or fuel surface, offering efficient cooling and blanket suppression at the source. This combination minimizes the chance of vapor ignition or spread by wind while maximizing heat absorption and control. Handlines with fog patterns or operations from ground or aerial positions tend to require closer placement and can create more vapor or less precise cooling, making them less suitable for remote application in this scenario.
