14. Service Precautions
a. Handling Refrigerant 12
Refrigerant 12 is stored and shipped as a liquid
under piessure contained in heavy metal drums
in 10, 25, and 145 pound sizes. Correctly handled,
it is as safe as compressed air. Incorrectly
handled, it can explode and cause serious damage.
In handling refrigerant drums, always observe
the following safety precautions.
1. Do not leave drum uncapped. The metal
cap furnished with the drum when it is shipped
is to protect the valve in case the drum is ac-
cidentally knocked over. This eliminates the
possibility of the drum flying through the shop
and causing serious damage to people and prop-
erty. A safety plug is also provided on the valve
in case the temperature exceeds the safe limits
of the drum. The cap is designed so that if the
safety plug at the valve should blow, the refriger-
ant will escape without causing the drum to move.
2. Do not overfill drum. A safety plug is pro-
vided in case the temperature of the refrigerant
exceeds the safe limits of the drum. However,
if the drum is overfilled, the pressure created
