guishing agent does not contain oxygen in
any form for supporting combustion or sus-
taining human life in breathing. Caution

been thoroughly ventilated with fresh air, a
self- contained breathing apparatus must be
worn when entering enclosed areas where

out of fumes and oxygen-starved area cre-
ated by the C02 gas.
Operators must hold release nozzle horn by

erates extreme cold which can cause per-
sonal injury.

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.
