LP (Propane) Tanks - Various Suppliers Informative - Grilling Season Is Here - Beware Of Potentially Dangerous LP Tanks

Review by Hugh_Jorgen on 2008-06-16
Now that grilling season is upon us, many of us will be running down to the corner store and exchanging our empty gas grill bottle for a freshly refilled one.

But inspect that new tank carefully - apparently, the folks out there running Meth labs have been using some of these LP tanks for the storage of Anhydrous Ammonia that's used in their Meth processing. They are then returning these contaminated tanks to local stores and exchanging them. Some of these tanks are getting refilled and being sent back into the market.

The trace amounts of Ammonia in the tank will cause rapid disintegration of your grill from the inside out, but more importantly, it will degrade the valve at the top of the cylinder - with potentially disastrous results.

A contaminated valve will have a blue-green color to it, almost like aged copper. You might also notice the smell of ammonia around the tank. If you encounter one of the tanks - LEAVE IT ALONE and call your local fire department immediately.

There is more info, as well as photos of the valves in question at the Propane Gas Assocation's web site -

Hugh, if I get a tank with one of these blue-green thingies on it, will I get a cheap high? :)

Good info, thanks.

Thanks for the info. We grill all the time and I was unaware of this problem.

Wow Hugh thank you so much for posting this! I grill darn near every night in the summer time and wouldn't have given the valve on the tank a second thought, other than it looked funny. If you don't mind I am going to forward this to my family, thank you again for posting this.

You should get your tank refilled instead of trading in the tank. It may take a few minutes, but it's for your safety.
