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
created by the CO2 gas.
Operators must hold release nozzle horn by
its handle or wear thick gloves to protect
hands from freezing to nozzle. CO2 gas gen-
erates extreme cold which can cause per-
sonal injury.
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.
