Propane Facts

  • Propane is an odorless gas. The smell of propane is an additive for safety.
  • Propane is a hydrocarbon made up of 3 Carbon atoms and 3 Hydrogen atoms (C3H8).
  • Propane is a by-product of natural gas and crude oil.
  • Propane exists as both a liquid and a gas.
  • Propane is 270 times more compact as a liquid than a gas.
  • Propane gas is heavier than air, so it will accumulate at the lowest point in the area.
  • Propane is environmentally friendly. It is considered one of the cleanest burning fuels. Since it becomes a vapor outside of the tank, it poses no risk of contaminating soils in the event of a leak.

Propane Leak

How do you tell if there is a propane leak?

propane smells like rotten eggsBy the smell. A disagreeable odor (similar to rotten eggs) is added to propane so that you will be able to detect the smell easily in case a leak develops.


If you think you smell propane...


  • Extinguish all smoking materials and any other open flames or sources of ignition.
  • Get everyone outside and away from the building.
  • Shut off the gas supply at the tank.
  • Call your propane supplier from a neighbor’s phone. If you cannot reach your supplier, call the fire department.
  • Stay outside and leave the gas off until the leak has been fixed.


  • Turn light switches, appliances or thermostats on or off, and do not use the telephone. A spark from one of these could ignite the gas.
  • Light or try to re-light any appliances. Leave this job to your propane supplier.
  • Re-enter the building, until the problem has been corrected.
