When storing LPG or compressed gas cylinders, it’s important to follow the relevant Australian Standards including AS 4332 The Storage and Handling of Gases in Cylinders and SafeWork guidelines.
(The information below is provided as a general guide to safe storage of gas cylinders in accordance with Australian Standards and SafeWork regulations. Always consult your site safety officer, gas supplier, and local regulatory authority to confirm compliance for your specific application.)
Below are the key safety points to help you ensure your site is compliant and safe.
1. Store cylinders upright and restrained: Always keep cylinders standing upright and secured with a chain, strap, or purpose-built bracket. This prevents them from falling, rolling, or damaging the valve assembly.
2. Ensure adequate ventilation: Gas cylinders must be stored in a well-ventilated area to prevent the build-up of gas.
Avoid enclosed rooms or sealed sheds. Outdoor storage cages with mesh sides, such as the GSC210, are ideal.
3. Keep away from heat and ignition sources: Cylinders should be kept at least 3 metres clear of flames, sparks, welding equipment, or electrical panels. Avoid exposure to direct sunlight or other heat sources.
4. Separate incompatible gases: Flammable gases (e.g. LPG, acetylene) must be kept separate from oxidising gases (e.g. oxygen).
Maintain a 3 m separation distance or install a non-combustible fire-rated wall between them.
5. Use a stable, non-combustible surface: Place the cage or cylinders on a level concrete pad or similar solid surface. Do not store cylinders directly on soil, grass, or uneven ground.
6. Secure the storage area: Use a lockable, ventilated cage to restrict unauthorised access. Cages should be positioned in a safe, accessible area away from traffic and building exits.
7. Display correct safety signage: Install appropriate signs such as “Danger – Flammable Gas” and “No Smoking or Open Flames”. Signage should comply with AS 1319 – Safety Signs for the Occupational Environment.
8. Keep the area clean and clear: Maintain good housekeeping. Keep the area around the cylinders free of rubbish, vegetation, and other combustible materials.
9. Separate full and empty cylinders: Label and store full and empty cylinders in clearly defined areas. This helps prevent confusion during use and emergency response.
10. Inspect regularly: Regularly check cylinders for damage, corrosion, leaks, or missing labels. Ensure anchor bolts, hinges, and locks on the cage remain secure.
11. Keep Safety Data Sheets (SDS) accessible: An SDS for each stored gas must be kept near the storage location and available to workers at all times.
12. Plan for emergencies: Ensure fire extinguishers and emergency contacts are nearby and visible. Staff should be trained in the correct handling of gas cylinders and emergency procedures.
