Understanding and following the steps and precautions to take when filling portable cylinders can avoid accidents:

Before filling any of the cylinders listed above, be sure to complete the following steps:

  • First, verify that the cylinder is designed to hold propane.
  • Second, verify that the cylinder is free of any defects that require rejection or requalification.
  • Third, check the latest test date to be sure that the cylinder is not due for requalification.

If the cylinder is 40 lb or smaller, used in vapor service (not a horizontal or motor fuel cylinder), and not equipped with an overfilling prevention device (OPD), it cannot be filled in most jurisdictions until an OPD is installed.
