Compressed Gas Signs
Welding shops, medical storage rooms and repair garages keep compressed gas cylinders in racks, and this sign marks the area at the door. Pair the NO SMOKING line with the rack location so staff know where the rule applies.

Where compressed gas signs are used
Machine shops, dental labs and hospital maintenance rooms post this sign on the door of a cylinder room or the wall beside a cage. Welding trucks and mobile repair vans carry a small one on the rear door where bottles ride upright. It also goes on a gas storage cage at a brewery, where a cylinder is swapped each week and a delivery driver needs to see the rule before entering.
Choosing the size and where to hang it
Place the sign on the door of the cage at about eye level, where a person sees it before unlocking. The 24 in x 18 in size works for a standard cage door, and the 36 in x 24 in size suits a gate or a wide storage wall. Aluminum with holes is the choice for a damp or outdoor cage, while plastic is light and works in a dry indoor room with grommets and zip ties.
Questions about compressed gas signs
Caution or Danger?
Yellow Caution is the default when the injury risk is minor or moderate. Choose red Danger when the gas could cause death or serious injury. Your safety officer should make that call for the gas you store.
Is a sign enough to secure cylinders?
No. A sign marks the area but does not secure a cylinder. Use chains or racks for the cylinders, and check your local code and safety officer for storage and labeling rules that apply to your site.
Which size fits a cage door?
The 18 x 12 in landscape size fits a cage door, and the 24 x 18 in landscape size fits a wall beside a rack. Aluminum with 1/4 in holes at the four corners screws flat to a wall. Plastic with brass grommets suits a lighter spot.
Can I put a shop name or a gas type on it?
The optional extra line can hold a gas type, a cage number or a shop name. Keep it short so NO SMOKING stays readable from the aisle. Leave it blank when a plain warning is enough. Check your state and local rules for the labels and storage that apply to your cylinders.
Is aluminum or plastic better for a cylinder cage?
Aluminum is .040 in and rust-free, so it suits a cage outdoors or in a damp garage. Plastic is .020 in styrene and light, which suits a dry indoor room with grommets and zip ties. Pick by where the cage sits, not by the look of the sign.
