Storing Propane Cylinders Safely, at a Glance
Stored well, a propane cylinder is safe and ready when you need it; stored carelessly, it's a real hazard. This guide covers where a cylinder belongs, how to check it before use, and what to do with an 'empty' one in plain English. There's a printable 29-page version up top.
Common Questions
1 Where should I store a propane cylinder?
Outdoors, in the open air, standing upright — never inside the house, a basement, or an attached garage. Keep it away from heat, direct prolonged sun, and anything that could spark or flame.
2 Do I need to store an empty cylinder the same way?
Yes. A cylinder that reads empty still has some propane and vapor inside. Treat it the same as a full one: outdoors, upright, valve closed.
3 How do I check a cylinder before I use it?
Look over the valve and connection for dents, corrosion, or damage, and make sure any rubber seal looks intact. If anything seems off, don't connect it — have your propane dealer take a look.
4 Can I fill my own cylinder?
Filling is best left to a reputable propane dealer or exchange station. Modern cylinders include an overfill-protection device, and the people who fill cylinders every day are set up to work with it correctly.
5 Where should I connect a cylinder to my generator?
Outdoors only, and clear of where the generator's own exhaust runs. The same carbon monoxide danger that applies to the generator applies to anything sitting near its exhaust.
6 What should I do if I smell gas near a cylinder?
Leave the area, get everyone to a safe distance, and call from there — never search for a leak yourself or create a spark nearby. Our gas-leak guide walks through the full steps.
