Propane (LP Gas) Safety

Propane fuels heaters, roofing torches, forklifts and kettles on many sites. It’s heavier than air, so leaks collect in low spots like basements, trenches and pits, where a spark can ignite them.

• Construction
• General Industry

Storage

• Store cylinders outdoors in a secure, ventilated area, away from building openings, drains and ignition sources
• Upright, secured, with valves closed (and caps on, when provided)
• Not stored inside buildings except as specifically allowed by rule
• Protected from vehicle traffic and heat

Using propane

• Inspect hoses, regulators and fittings before connecting.
• Check new connections for leaks with soapy water, never a flame.
• Use heaters and torches designed for propane, per the manufacturer.
• Forklift cylinders: mount horizontally with the alignment pin in place; wear gloves and eye protection when changing them, since liquid propane causes frostbite.
• Close cylinder valves when equipment isn’t in use.
