Like any fuel, propane is combustible and should be handled properly. Propane in cylinders should be stored in an authorized location (outside, detached storage with adequate ventilation is preferred) and should be isolated from heat and ignition sources. Separate storage locations should be provided for other compressed or flammable gases. Propane cylinders should be checked frequently for leaks, dents gouges and corrosion with emphasis placed upon the bottom of the cylinder. Cylinders are to be stored in an upright position and are not to be dropped or abused. The container valve should be closed and plugged when not in use. Empty cylinders retain some residue, so they should be treated as if they were full.

Whether you're transporting your propane cylinder or storing it for future use, you need to handle it carefully. Here are some guidelines you should follow:

Propane cylinders must be transported so the relief valve communicates with the vapor space at all times. For that reason, you should never transport a cylinder lying on its side unless it's a cylinder designed for horizontal use. When transporting disconnected cylinders, the container outlets must be plugged or capped. This will keep gas from escaping and prevent foreign material from entering the cylinder should the valve be opened accidentally. The threaded safety plug has left-hand threads, so you'll have to turn it counter-clockwise to tighten it. Never use, store or transport full cylinders or empty ones in the passenger space or living area of your RV or camper. Never store a cylinder inside a building, including a garage. Spare cylinders, for instance, should be stored outdoors and up off the ground on a non-combustible base. Another good practice when storing a cylinder is to plug or cap the service valve outlet. Any cylinder that is damaged, shows signs of corrosion, has been exposed to fire, or appears to be leaking gas should be removed from service immediately. Store defective cylinders in a safe, outdoor location. Then as soon as possible, have them repaired or disposed of by a qualified service technician.
