    Which of these does the manual list as special purpose equipment to check on a tank vehicle?

    The answer

    Answer: D. The list also includes vapor recovery kits, emergency shut-off systems and a built-in fire extinguisher. If your vehicle has the equipment, make sure it works. Livestock ramps, refrigeration units and hydraulic dump hoists belong to other vehicles, while grounding and bonding cables help prevent sparks when handling flammable liquids.

  2. Emergency systems2 of 2

    What must you do before moving a tank of hazardous materials, however small the amount or short the trip?

    The answer

    Answer: A. Manholes and valves must be closed to prevent leaks. Open vents, capped hoses and the manufacturer's label do not prevent spills, because open manholes or valves allow liquid or vapor to escape, even on a short trip with a small amount.
