Safety Practices
If liquid argon or nitrogen is used, the gas cylinder must be fitted with an over-
pressure regulator, which will vent the cylinder as necessary to prevent it from
becoming a safety hazard.
Listed below are some general safety practices for the proper identification,
storage, and handling of gas cylinders. Consult References 3 and 4 on page 53 for
more detailed information and additional guidelines.
Identification of Gas Cylinders
•
Legibly mark cylinders to identify their contents. Use the chemical name or
commercially accepted name for the gas.
Storing Cylinders
•
Cylinders should be stored in accordance with the regulations and standards
applicable to the customer’s locality, state, and country.
•
When cylinders are stored indoors in storage rooms, the storage room should
be well ventilated and dry. Ensure that the ventilation is adequate to prevent
the formation of dangerous accumulations of gas. This is particularly important
in small or confined areas.
•
Do
not
store cylinders near elevators, gangways, or in locations where heavy
moving objects may strike or fall against them.
•
Use and store cylinders away from exits and exit routes.
•
Locate cylinders away from heat sources, including heat lamps. Compressed
gas cylinders should not be subjected to temperatures above 52 °C (126 °F).
•
Do
not
allow ignition sources in the storage area and keep cylinders away from
readily ignitable substances such as gasoline or waste, or combustibles in bulk,
including oil.
•
Store cylinders standing upright, fastened securely to an immovable bulkhead
or permanent wall.
•
When storing cylinders outdoors, they should be stored above ground on a
suitable floor and protected against temperature extremes (including the direct
rays of the sun).
