Storage Guidance

• Store cylinders in a well-ventilated covered area, preferably outside on a level, well-drained surface. If this is not reasonably practicable, store in an adequately ventilated building or part of a building specifically reserved for this purpose
• Full and empty cylinders should be stored separately
• Cylinder stocks should be rotated so that the oldest cylinders are used first
• Cylinders should be stored vertically and securely fastened to prevent them from falling over
• Segregate cylinder by properties of gas - Flammable, Oxidising, Inert etc.
• Ensure that gas cylinder valves are kept shut on empty cylinders
• Avoid storing gas cylinders so that they stand or lie in water - Oxygen must be stored away from oil or grease
• Protect gas cylinders from external heat sources that may adversely affect their mechanical integrity
• Gas cylinders containing flammable gas should not be stored in part of a building used for other purposes
• Do not store other products in a cylinder store, in particular flammable materials such as fuel, oil, paint or corrosive liquids
• Gas cylinders must be clearly marked to show what they contain and the hazards associated with their contents
• Store cylinders where they are not vulnerable to hazards caused by impact from vehicles such as fork-lift trucks
• Do not store LPG cylinders within three metres of other gas cylinders - The use of a firewall reduces the distance to 1.5 meters

There are specific requirements for certain products. Storage of cryogenic, liquefied (e.g. Propane) and heavier than air compressed gases should be sited with due regard to the dangers of gases collecting in low-lying areas such as drains, basements and ducts.

It is advisable to label your storage area with relevant hazard labels and colour code chart.
