What Happens If I Let My Tank Run out of Propane?

March 12, 2018 –

Running out of propane is a serious no-no that can cause all kinds of problems — and potential dangers — for you in your propane-powered home.

In fact, one of the best ways to practice propane safety is to make sure you never run out of propane gas!

Consider the following consequences of letting your propane tank run out:

  • If a valve or gas line is open when the propane supply runs out, a leak can occur when the system is recharged with propane.
  • Air and moisture that penetrate an empty propane tank can cause rust build-up inside the tank. Rust decreases the concentration of the odor of propane, making it more difficult to smell.
  • Any pilot lights on your appliances will go out if your propane tank runs out -– a problem that can be extremely dangerous if not handled properly.
  • Any interruption in service, including an out-of-gas call, requires that a qualified technician perform a leak test–paid for by you–to meet federal code requirements (National Fuel Gas Code Section 4.2.1/4.2).

The bottom line: Don’t run out of propane!

    We use propane gas tfor our hot water heater. This is the first time in 33 years that we ran out of gas …..today. We are concerned. We cut off the switch to the tank for the gas coming to the house. How long can you be out of propane gas in your tank before it is considered dangerous. Thanks

      Hi Anita! Your supplier will need to do a leak check after filling the tank and turning the system back on.

    I like what you said about your tank developing a leak when you run out of propane. My sister has been telling me about how she wants to start using propane to heat her home soon. I’ll share this information with her so that she can look into her options for propane services that can help her with this.

    It’s helpful that you mentioned that an empty propane tank can be very susceptible to rusting. I’m going to keep that in mind when finding a propane delivery service soon. I’d like to make sure that I wouldn’t have an empty tank for a long amount of time in order to avoid damaging it.

    If I left the heat on and propane runs out and then is refilled while valve inside the building is still open, what are the dangers? Will it continue to fill the room with propane gas?

      Hi JW! If you experience an interruption of service due to your gas supply running out your propane company, after refilling the container will turn the service valve off until a leak check can be done. During a leak check, the propane company verifies that your gas line holds pressure for 3 minutes with no equipment running to ensure that gas is not escaping into the home. At that point, the container valve can be reopened and regular appliance use resumed.

    This is the second time in a row my provider has allowed my propane tank to run empty. They said we may have to wait five days for a refill. Our house only runs on propane for heat. Is this legal for them to leave us without any way to heat our house? We have a sensor on our tank
