Safety Alert
Importance: High
Albany State University Police Department
Subject: Summer Safety Alert
Methamphetamine cooks are buying propane tanks from the exchanges at
Wal-Mart, Kroger, and emptying them of the propane gas. Then they fill
the propane tanks with anhydrous ammonia, which they now have a recipe
to cook Methamphetamine. After they are finished with the propane tanks,
they return them to the store. The stores refill the tanks with propane
gas, unknowing to them the improper substance that was inserted in the
tanks and sell them to their consumers. Anhydrous ammonia is very corrosive
and weakens the structure of the tank. It can be very dangerous when mixed
with p ropane gas and hooked up to a grill, recreation vehicle, etc.
You should inspect the propane tank for any blue or greenish residue around
the valve areas. If there are evidences of these substances, do not purchase
the propane tank and advise the vendor of your findings.
The information was researched, and you should check out the following
website for more details. They also have pictures for you to view.
