You are hauling compressed gas cylinders in a vehicle that has no racks for them. Which loading method is acceptable?

Correct answer: Upright or lying flat, braced so they cannot move.

Answer options

  1. ALeaning against a side wall with no bracing at all
  2. BStacked in loose layers close to the rear doors
  3. CUpright or lying flat, braced so they cannot move Correct

Why

Without racks, the cylinders can ride either standing up or lying down, provided they are secured against shifting while the vehicle moves. A loose or leaning cylinder can fall, and a broken valve could release gas under high pressure.
