Propane is a very safe fuel. But as with any energy source, there are steps you should take to further ensure your safety. The following is information you can use to learn more about propane.

Odor loss also can diminish propane's smell.
On rare occasions, propane can lose its odor. Several things can cause this including:
Since there is a possibility of odor loss or problems with your sense of smell, you should respond immediately to even a faint odor of gas.
If you are concerned that you or others in your home may have difficulty smelling propane, consider buying one or more propane gas detectors.
If you smell gas inside or outside of your home:
No flames or sparks! Immediately put out all smoking materials and other open flames. Do not operate lights, appliances, telephones, or cell phones. Flames or sparks from these sources can trigger an explosion or a fire.
Leave the area immediately! Get everyone out of the building or area where you suspect gas is leaking.
Shut off the gas. Turn off the main gas supply valve on your propane tank, if it is safe to do so. To close the valve, turn it to the right (clockwise).
Report the leak. From a neighbor’s home or other building away from the gas leak, call your propane retailer right away. If you can’t reach your propane retailer, call 911 or your local fire department.
Do not return to the building or area until your propane retailer determines that it is safe to do so.
Get your system checked. Before you attempt to use any of your propane appliances, your propane retailer or a qualified service technician must check your entire system to ensure that it is leak-free.
