Which is a practice of fueling from one truck to another, not allowed?

• A. Vapor Hose
• B. Hot Hose
• C. Dry Hose
• D. Wet Hose

Answer: (D)

Transferring fuel between trucks using a hose that already contains product creates a high spill and ignition risk. When the hose is “wet” with fuel, any movement, disconnect, or misalignment can cause fuel to drip or spray, and the continuous liquid path can vent vapors or trap pressure, increasing the chance of a spill, exposure, or fire. Static electricity buildup during flow is another concern, and without proper controls, cross-contamination between loads and uncontrolled releases are more likely. Safer practice uses a dry hose system or transfers through approved equipment with proper bonding, grounding, shutoffs, and containment, so the line is kept free of product until a controlled connection is made and any spills can be quickly managed. In short, a hose that’s charged with fuel during a truck-to-truck transfer is not allowed because of the higher risk of spills, vapors, and ignition.
