Do I really need to turn off the propane tank after grilling?

Asked by alabare (282points) January 29th, 2008

I have a really nice grill. Just wondering with these higher end grill models if it’s really necessary to turn off the valve after each use. Dad always taught me better to be safe than sorry, but was just curious.

It doesn’t so much have to do with the grill as with the tank. There’s two reasons to turn off the tank:

1. Save gas—if there’s a very small leak, you will suddenly come out to find an empty tank when you go to grill.

2. Fire safety—the interior of the grill is enclosed, if there’s a leak into there, the grill may build up enough gas to cause an explosion or fire if there’s a small source of flame nearby (cigarette, static from a cat’s fur, etc.)

The aside here is that when you open the valve on the tank you should make sure you open it all the way—tank valves are “double sealing” meaning they seal when open and when closed, but not necessarily in between. So if the valve isn’t all the way open, you may be losing gas out the top. Usually not enough to cause a fire, unless it builds up somewhere, but why lose gas you paid for?

Yes, I am a firefighter turn it off your connections could leak and propane is heavier than air and pools instead of dissipating like natural gas which means it sits or collects until it finds an ignition source or is mechanicaly moved. BE SAFE ALWAYS

I only turn it off about half the time. I know i should do it every time but I either forget, or am too lazy, or have something in my hand, or…. I have not noticed a difference.
I definitely turn it off if the grill is not going to be used for a while, e.g. more than a week.
