Refilling Small Cylinders

MAKE SURE YOUR CYLINDER IS EQUIPPED WITH AN OVERFILL PREVENTION DEVICE(OPD).

An OPD is a safety feature that helps prevent small propane cylinders from being overfilled. An overfilled cylinder doesn’t have enough space left if the liquid expands when exposed to warmer temperatures. This can cause an increase in cylinder pressure and create potentially hazardous conditions.

Most cylinders with OPDs have special triangular handwheels with the letters “OPD” on them. In many states, cylinders without OPDs cannot be refilled. If you are uncertain as to whether your cylinder has an OPD valve on it, ask your propane retailer.

OLD OR DAMAGED CYLINDERS

NEVER use a damaged cylinder or a cylinder that been in a fire. All cylinders must be inspected before they are refilled. The law requires periodic inspection of cylinders, and it is against the law to refill out-of-date cylinders. The last inspection date is stamped on the cylinder.

DISPOSAL OF CYLINDERS

NEVER dispose of your propane cylinder by throwing it in the trash. Check to see if there are municipal programs for collection in your area, or contact your propane retailer for guidance on disposal of the cylinder.
