Propane Bottle—Cylinder & Tank
In 2002, a federal regulation went into effect requiring portable propane tanks from four to 40 pounds to be equipped with Overfilling Prevention Devices (OPDs), a safety feature that helps prevent small propane cylinders from being overfilled. When the propane liquid fills approximately 80 percent of a cylinder's volume, the OPD mechanism shuts off the liquid flow into the container, allowing room for the gas to expand during warmer weather.
Propane filling stations are no longer permitted to fill tanks that are not properly fitted with the device. This will affect many users of older travel trailers, fifth wheels, tent campers, park trailers, and gas barbecue grills.
Consumers who are not sure if their cylinder has the OPD can check by looking at the valve on the tank. Old valves have a round hand wheel, but the newer OPD valves are triangular in shape and marked “OPD” on the valve body. Consumers who do not have an OPD equipped cylinder should contact their local gas supplier for information on replacing the valve or cylinder.
Propane bottles (including the small screw-on cook stove bottles), cylinders, and tanks without an OPD can be taken, free of charge, to any of the County's household hazardous waste collection facilities.
