“Safe Storage of Compressed Gas Cylinders”

Key Hazards

Cylinders falling, tipping, or being struck
Valve damage causing uncontrolled gas release
Flammable or oxidizing gases stored near ignition sources
Incompatible gases stored together
Cylinders exposed to heat, weather, or physical damage
Leaks from valves, caps, regulators, or fittings

2–3 Minute Talk Script

Compressed gas cylinders store high-pressure energy and can become extremely dangerous if they fall, are damaged, or have a valve broken off. Safe storage is one of the most important controls.

Cylinders should be stored upright and secured with chains, straps, racks, or other approved restraints. A freestanding cylinder can be knocked over by a person, cart, forklift, or door.

Valve protection should be in place when required. Caps help protect valves during storage and movement, and cylinders should never be lifted or pulled by the cap or valve.

Cylinders should be stored away from heat, sparks, flames, electrical hazards, traffic areas, and locations where they could be struck or damaged.

Different gases may need to be separated. Flammable gases, oxygen, oxidizers, inert gases, and other cylinders should be stored according to compatibility requirements and site procedures.

Labels and markings should remain readable. Workers should be able to identify the gas and whether the cylinder is full, empty, in use, or damaged.

Leaks should be reported immediately. Workers should not attempt improvised repairs on leaking cylinders, valves, or fittings unless they are trained and authorized.

Safe cylinder storage depends on preventing movement, impact, heat exposure, and confusion. Secure cylinders, protect valves, separate incompatible gases, and keep the storage area organized.

Safety Reminders

Store cylinders upright and secured.
Use valve caps when required.
Keep cylinders away from heat, sparks, flames, and impact areas.
Separate incompatible gases according to procedure.
Keep labels and markings readable.
Identify full, empty, and damaged cylinders clearly.
Report leaking or damaged cylinders immediately.

Ask the Crew

Are cylinders secured so they cannot fall or tip?
Are valve caps installed where required?
Are cylinders protected from heat, traffic, and impact?
Are incompatible gases separated correctly?
Are cylinder labels readable and leaks being reported?
