LPG Handling and Storage: Propane Safety for Small Businesses
Overview
Liquefied petroleum gas (LPG), commonly called propane, is a highly flammable fuel used for heating, cooking, forklifts, and various industrial applications. Safe handling and storage of LPG cylinders and tanks prevents fires, explosions, and asphyxiation hazards in workplace environments.
Why This Is Important
LPG is heavier than air, accumulating in low areas where ignition sources can trigger explosions. Leaking propane displaces oxygen, creating asphyxiation risks in confined spaces. Improper storage near ignition sources or inadequate ventilation has caused devastating fires and explosions. Understanding LPG properties and following safe practices protects workers and facilities.
Best Practices & Safety Tips
- Store LPG cylinders outdoors in well-ventilated areas away from building openings, ignition sources, and high traffic zones
- Keep cylinders upright and secured to prevent tipping, with protective valve caps in place when not in use
- Maintain at least 20 feet clearance between LPG storage and any ignition sources including electrical panels and welding operations
- Inspect cylinders, hoses, and connections regularly for damage, corrosion, or leaks before each use
- Use leak detection solution (soap and water) to check connections—never use open flames to detect leaks
- Transport cylinders in well-ventilated vehicles with valves closed and cylinders secured to prevent movement
- Never store or use LPG cylinders in enclosed spaces, basements, or near floor drains where gas can accumulate
- If you smell propane (mercaptan odorant), evacuate the area immediately, eliminate ignition sources, and call emergency services
- Ensure only trained personnel connect, disconnect, or service LPG equipment and cylinders
- Post “No Smoking” and “Flammable Gas” signs in LPG storage and use areas
Discussion Questions
- Why must LPG cylinders be stored outdoors or in well-ventilated areas?
- What should you do if you smell propane in your work area?
- How do you properly check for leaks on LPG connections?
- What ignition sources must be kept away from LPG storage areas?
- Why is propane more dangerous than natural gas in terms of accumulation hazards?
Takeaway
Liquefied petroleum gas provides convenient, efficient energy but demands respect and proper handling. Outdoor storage, leak detection, and keeping ignition sources separated are non-negotiable requirements—the explosive nature of LPG means that shortcuts can result in catastrophic consequences.
