Untitled Document back to index 5. Cylinders may be stored in the open only if protected from the weather, i.e. away from ground dampness and away from direct sunlight.
Bulk storage is to be in approved rooms or outside enclosures.
Bulk storage cylinders should be chained and security measures taken to prevent tampering and loss. Do not store empty cylinders with full ones, and do not place cylinders where they may become part of an electrical circuit. All gas cylinders in service or storage, empty or full, shall be securely held upright in substantial racks or secured to other rigid structures so that they will not fall or be knocked over. Cylinder caps should be kept in place during storage. All cylinders are to be considered full unless properly identified as empty.
