  • Never leak test while smoking.


LP gas and natural gas have manmade odorants added specifically for detection of fuel gas leaks.If a gas leak occurs you should be able to smell the fuel gas. Since Propane (LP)is heavier than air you should smell for the gas odor low to the floor. ANY GAS ODOR IS YOUR SIGNAL TO GO INTO


  • Do not take any action that could ignite the fuel gas. Do not operate any electrical switches.Do not pull any power supply or extension cords. Do not light matches or any other source of flame. Do not use your telephone.
  • Get everyone out of the building and away from the area immediately.
  • Close all propane (LP) gas tank or cylinder fuel supply valves,or the main fuel supply valve located at the meter if you use naturalgas.
  • Propane (LP) gas is heavier than air and may settle in low areas. When you have reason to suspect a propane leak, keep out of all low areas.
  • Use your neighbor’s phone and call your fuel gas supplier and your fire department. Do not reenter the buiding or area.
  • Stay out of the building and away from the area until declared safe by the firefighters and your fuel gas supplier.
  • FINALLY, let the fuel gas service person and the firefighters check for escaped gas. Have them air out the building and area before you return. Properly trained service people must repair any leaks, check for further leakages, and then relight the appliance for you.
