How should refrigerant cylinders be secured during transport in a service vehicle?
a.Laid loose in the bed so they can roll freely
b.Left with the valve caps off for quick access
c.Upright and secured, valve caps on
d.Stacked horizontally without restraint
Explanation
Cylinders should be transported secured in an upright position and restrained so they cannot fall or roll, with valve protection caps installed to protect the valve. Letting cylinders roll loose or stacking them unrestrained risks valve damage and a dangerous release, and caps should stay on until the cylinder is in use. A snapped-off valve can turn a cylinder into a dangerous projectile.
