Recommendations for compressed gas systems
Gas installations
•
Legibly mark gas lines and outlets to clearly identify the contents. Use the chemical name or
commercially accepted name for the gas.
•
Use only approved regulators, tubing, and hose connectors.
•
Arrange gas hoses where they will not be damaged or stepped on and where things will not
be dropped on them.
•
Check the condition of pipes, hoses, and connectors regularly, and replace any damaged
parts.
•
Perform periodic gas leak tests at all joints and seals of the gas system by applying an
approved gas leak detection fluid.
Using gas cylinders
•
Store cylinders in accordance with the applicable national, state, and/or local regulations and
standards.
•
Legibly mark cylinders to clearly identify the contents and status—full or empty. Use the
chemical name or commercially accepted name for the gas.
•
When gas cylinders are stored in confined areas, such as a storage room, make sure that
ventilation is adequate to prevent toxic or explosive accumulations of gas.
•
Do not store acetylene in close proximity to oxidizing gases, such as nitrous oxide.
•
Store all gas cylinders upright, with the valve cap in place, in a dry, well ventilated area,
protected against temperature extremes.
•
Do not locate gas cylinders near exits and exit routes, elevators, gangways, or in locations
where heavy moving objects may strike or fall against them.
•
Locate gas cylinders away from heat sources, including the direct rays of the sun, and away
from ignition sources and readily ignitable substances, such as gasoline, oil, or combustible
waste. Compressed gas cylinders should not be subjected to temperatures above 52 °C (126
°F).
•
Locate all gas cylinders only in a vertical position, fastened securely to an immovable
bulkhead or a permanent wall.
•
Move cylinders with a suitable hand truck after making sure that the valve cap is securely in
place and that the cylinder is properly fastened to the hand truck.
•
Do not attempt to refill gas cylinders.
