Argon gas must be stored at a specific temperature in order to maintain the bottle's integrity. Argon should never be stored in an area that is hotter than 122 degrees or colder than minus 22 degrees. Do not store argon bottles in direct sunlight.
All gas containers, regardless of content, should be stored upright with their valve protection caps in place. Always move bottles with cylinder dollies or portable racks; never roll or drag a bottle.
Store argon bottles in an area away from foot and vehicle traffic to reduce the risk of accidental damage. Indoors, use a well-ventilated storage area. Outdoors, use a storage area that's protected from weather and equipped with a lock to prevent tampering.
