This document is a "Guide Only", and is not a comprehensive checklist for truck inspections. Please refer to
"B620/98 or 87" for complete requirements.

All tank inlets and outlets, except safety relief valves, shall be marked to designate whether they communicate
with vapour or liquid when the tank is filled to the maximum permitted filling density. For example: a spray fill
connection is considered a vapour valve because it communicates with the vapour space of the tank.
