CAUTION: A small liquid relief valve set to 11/3 times the test
pressure is recommended for the pressure test system, in case
a vessel, while under test, is likely to be warmed up materially
with personnel absent.
(i) Vents shall be provided at all high points of the vessel
in the position in which it is to be tested to purge possible
air pockets while the vessel is filling.
