Safety Information for Users of LP Gas 

 

Propane (LP Gas) is a flammable gas which can cause fires and explosions. In its natural state, propane is odorless and 
colorless. You may not know all the following safety precautions which can protect both you and your family from an accident. 
Read them carefully now, then review them point by point with the members of your household.   Someday, when there may not 
be a minute to lose, everyone’s safety will depend on knowing exactly what to do. If, after reading the following information, you 
feel you still need more information, please contact your gas supplier. 

 

 

LP Gas Warning Odor 

If a gas leak happens, you should be able to smell the gas because of the odorant put in the LP Gas. 

That’s your signal to go into immediate action! 

 

 

Do not operate electric switches, light matches or use your phone.  Do not do anything that could ignite the gas. 

 

IMMEDIATELY get everyone out of the building, vehicle, trailer or area.  

 

Close all gas tank or cylinder supply valves. 

 

LP Gas is heavier than air and may settle in low areas such as basements. When you have reason to suspect a gas  

      leak, keep out of basements and other low areas. Stay out until firefighters declare them to be safe. 

 

Use your neighbor’s phone and call a trained LP Gas service technician and the fire department. Even though you may  

      not continue to smell gas, do not turn on the gas again.  Do not re-enter the building, vehicle, trailer or area. 

  Have the service technician or fire department air out the area before you return. Properly trained LP Gas service 

technician must repair the leak, check and relight the gas furnace for you.
