Safety
If you smell gas:
Put out all smoking materials or any open flames -- do NOT operate any electrical switches, thermostats, appliances, telephones/cell phones, ring doorbells.
Leave the area immediately -- get everybody out of the building.
Shut off the gas at the tank (if you have an on-lot tank) -- if it is safe to do so, turn the valve to the right (clockwise).
Do NOT start a vehicle if the gas leak is outside.
Report the leak.
If the gas smell is inside your house, call your furnace/appliance service provider.
If it is from the exterior of your home, call 215-766-8069 (Greenleaf Propane 24-hr no.).
If you cannot reach anyone, or a fire has started, call 911.
Do not return to the building/area until the professional responder has deemed it is safe to do so.
Get your propane system checked.
Before you use any of your applicances, the appropriate professional must verify there are no leaks.
The furnace/appliance service provider may need to re-ignite appliance pilot lights.
