11) The notes by the team member at the
cabinet are used to provide an accu-
rate layout of the accumulators, CO2
pipework, and their connections to the
detector modules.
12) It is necessary that each and every
accumulator be tested in this manner
to ensure accumulators are all con-
nected to the pipework and none are
blocked.

WARNINGS
CO2 (carbon dioxide) gas used as an extin-
guishing agent does not contain oxygen in
any form for supporting combustion or sus-
taining human life in breathing. Caution
must be used before entering any space
filled with CO2 gas. Unless the space has
been thoroughly ventilated with fresh air, a
self-contained breathing apparatus must be
worn when entering enclosed areas where
CO2 gas has been released.
When releasing CO2, operators must stay
out of fumes and oxygen-starved area cre-
ated by the CO2 gas.
The maximum safe storage temperature for
all CO2 cylinders is 130° F. To avoid acci-
dental release of CO2 gas through activation
of the cylinder safety relief valve, ensure
that each cylinder is kept or stored in places
where the temperature will not reach critical
levels.
