cabinet are used to provide an accu-
rate layout of the accumulators, C02
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
C02 (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 C02 gas. Unless the space has
been thoroughly ventilated with fresh air, a
self- contained breathing apparatus must be
worn when entering enclosed areas where
C02 gas has been released.
When releasing C02, operators must stay
out of fumes and oxygen-starved area cre-
ated by the C02 gas.
The maximum safe storage temperature for
all C02 cylinders is 130 °F. To avoid acci-
dental release of C02 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.
