  • AOpen valves quickly
  • BFollow procedures including bonding/grounding for flammables, monitor flow, secure when complete
  • CUnload in motion
  • DLeave hoses unattended

Correct answer: B. Follow procedures including bonding/grounding for flammables, monitor flow, secure when complete

How this question fits the Tanker test

Liquid surge can push a vehicle through an intersection or roll it on a curve. The Tanker endorsement specifically addresses how unbaffled and partially full tanks behave differently from rigid loads.

Study technique for this topic

Know the difference between baffled, unbaffled, and compartmented tanks, the safe outage percentage for liquid expansion, and why front-to-back surge is more dangerous than side-to-side surge.
