Improper storage of helium compressed gas can cause the helium-filled cylinder to fall, tip or be over-exposed to heat, which in turn can lead to a crack or weakness in the cylinder. The proper storage of helium compressed gas is essential for the safety of those handling it.
Label cylinders as "Full" or "Empty" (or "MT") and keep them separated.
Secure the helium cylinder upright to a sturdy, fixed structure. Use durable chains, straps or cable to secure the cylinder.
Label the helium cylinder. Using a permanent label or tag, mark the cylinder with the name of cylinder's contents, date of the cylinder's last use and the name of the person who last used the cylinder (if available).
Label the cylinder storage area with precautionary signs and place one or more signs in highly visible areas.
Put caps on all cylinders. Each cylinder must be capped at all times except when in use.
Store helium containers in a dry, well-vented area away from heat, flame, sparks and sockets. Exposure to salt can cause corrosion of the cylinders. Never tamper with any pressure-release device.
