LPG and Gas Cylinder Storage Safety
Liquefied petroleum gas cylinders are used on construction sites for heating, brazing, soldering, and hot works equipment. LPG is heavier than air and accumulates at low levels where it can find ignition sources. Cylinders are pressurised vessels that can explode if exposed to fire or heat. Correct storage, handling, and use of LPG cylinders prevents leaks, fires, and explosions. Every worker who handles or uses LPG must understand the storage requirements and emergency procedures.
- Store LPG cylinders upright in a well-ventilated outdoor cage away from buildings and ignition sources.
- Separate full and empty cylinders within the storage area and clearly label each group.
- Secure all cylinders with chains or straps to prevent them falling over during storage and transport.
- Check all hose connections, regulators, and valves for leaks using soapy water before each use.
- Keep LPG cylinders at least three metres from oxygen cylinders or separated by a fireproof barrier.
- Close cylinder valves fully when not in use and fit protective caps during transport and storage.
- Never use heat, force, or tools to open a stuck cylinder valve — return it to the supplier.
- Position a fire extinguisher suitable for gas fires within immediate reach of every LPG use location.
- Display no smoking signs and prohibit naked flames within the gas storage and use area.
If an LPG cylinder is involved in a fire, evacuate to at least 100 metres and call 999. Do not attempt to move or cool the cylinder. Warn others and prevent re-entry. An LPG cylinder in a fire can explode violently.
- LPG is heavier than air and accumulates in low-lying areas, pits, and basements at dangerous levels.
- Cylinders must be stored upright in a ventilated outdoor cage away from ignition sources.
- A leaking LPG cylinder in an enclosed space can create an explosive atmosphere within minutes.
- Check all connections with soapy water before use — never use a naked flame to detect leaks.
- A cylinder in a fire can undergo a boiling liquid expanding vapour explosion with devastating force.
- Keep LPG and oxygen cylinders at least three metres apart or separated by a fireproof barrier.
