OPD - Overfilling Protection Device

As of April 1, 2002, cylinders without OPDs cannot be refilled!
Beginning October 1, 1998, all newly manufactured small propane cylinders (capacity of 4 pounds up to 40 pounds) were required to be equipped with a over filling prevention device (OPD).


  • Avoid prolonged or repeated skin contact with fuel.
  • Wash skin thoroughly with soap and water in case of contact.
  • Avoid breathing vapors or mists.
  • Remove any clothing that is wet with fuel. Allow fuel to evaporate completely outdoors before washing. Thoroughly clean clothing before reuse. 


  • Handle any propane-powered equipment cautiously and always follow the manufacturer's instructions.
  • Cylinder tanks for equipment such as stoves and ovens must be located outside of the home.
  • Never store or use propane gas cylinders larger than one pound inside the home.
  • Never operate a propane-powered gas grill inside the home.
  • Have propane gas equipment inspected periodically by a professional for possible leaks or malfunctioning parts.
  • Carefully follow the manufacturer's instructions when lighting a pilot.
  • If you smell a strong odor of gas, leave the area immediately and call the fire department from outside the home.
  • For more information, please visit the Propane Education and Research Council Web site or give us a call!


  • Do not allow smoking, flames, or other sources of ignition near the fuel storage and handling areas. Gas vapors are heavier than air and will drift downward from the source. It is the vapor, not the liquid, which burns.
  • Follow safety recommendations of your fuel supplier during fuel delivery. Report fuel spills in accordance with regulations.
  • Use absorbent materials to clean up and prevent the spill from spreading.
  • Position the fuel delivery truck so that it does not interfere with the movement of other vehicles.
  • Make sure that fuels are delivered into the correct tank.
  • Check the levels in the tank to determine quantity needed before receiving commercial delivery.
  • Check the area around the vents of the receiving tanks for possible ignition sources.
  • Observe the vents during delivery for proper operation. Stop delivery if fuel is being ejected.
  • Have the driver stay near the truck flow valve while the fuel is flowing into the storage tank in case of the need for emergency shutoff.
  • Reinstall the fill and gauge caps.
  • Mark gauge and fill caps clearly to indicate the fuel type.
  • Open caps only during filling and gauging to minimize the release of fuel vapors
