tare weight
Determine and
record the total fill
weight adding tare
weight to
manufactures DOT
fill weight.
Place cylinder on
scale; compare
empty (tare) weight
of cylinder to tare
weight on DOT
plate - any overage
is residual gas
Sample residual
gas in cylinder;
purge the cylinder if
necessary
Open cylinder vent

open the shut off
valve of transfer
line allowing liquid
