Meth cooks are getting the propane tanks from the exchanges at Wal-Mart,
Kroger, gas stations, etc. and emptying them of the propane. They are
filling them with anhydrous ammonia (which is used in their meth
recipe). After they are finished with them, they return them to the
store.
They are then refilled with propane and sent back for you and me to buy.
Anhydrous ammonia is very corrosive and weakens the structure of the
tank. It can be extremely dangerous when mixed with propane and hooked
up to our grills, etc.
You should inspect the propane tank for any blue or greenish residue
around the valve areas. If it is present, refuse to purchase that one."
If you suspect you already have one of these tanks, don't touch it.
Notify the fire dept, DEA, or HazMat Emergency Response Unit immediately
for disposition.
Check out the following website for more details. They also have
pictures showing what contaminated tank valve might look like.

Responders to incidents involving anhydrous ammonia will require Level A chemical protective clothing and self-contained breathing apparatus (SCBA) to protect them or to perform rescue.
On Jan. 18, 2002, a Canadian Pacific freight train derailed outside Minot, ND. Five of the cars carried anhydrous ammonia. Leaking ammonia killed one person and sent dozens of others to hospitals for treatment. Ten of those seeking treatment were admitted to the hospital. Some local residents were evacuated while others were asked to shelter in place. Civil Defense sirens and local radio and TV stations alerted residents.
In 1984, one firefighter was killed and a second was burned over 72% of his body in an anhydrous ammonia explosion and fire that occurred in Shreveport, LA. Ammonia was leaking inside a cold storage building. While firefighters were working inside in Level A chemical protection, the ammonia reached an ignition source. Though it is listed as a non-flammable gas by DOT, ammonia burns inside structures and confined spaces; it is less likely to ignite out in the open. Precautions should be taken for ammonia leaks inside buildings just as for any other flammable gas.
An accident occurred in the late 1990s in a cold storage building in Ortana, PA. Two plant maintenance workers, who were also local volunteer firefighters, were conducting routine maintenance on liquid ammonia lines within the facility. A leak occurred, the men were splashed with liquid ammonia and both died. Firefighting personnel responding to the incident were burned by ammonia vapors as they entered the facility in turnouts to rescue the workers.
In Delaware County, PA, in the early 1990s, an ammonia leak occurred as workers were removing the material from a cold storage building. The entire first-alarm assignment was exposed to ammonia vapors and experienced symptoms. They all had to go through decontamination and medical treatment at the scene. Mild exposure to anhydrous ammonia can cause irritation to eye, nose and lung tissues. When NH3 is mixed with moisture in the lungs, it causes severe irritation. Ammonium hydroxide is actually produced in the lungs. Prolonged breathing can cause suffocation. The human eye is a complex organ made up of nerves, veins and cells. The front of the human eye is covered by membranes, which resist exposure to dust and dirt. None of these can keep out anhydrous ammonia, because the entire eye is about 80% water. A shot of ammonia under pressure can cause extensive, almost immediate damage to the eye. The ammonia extracts the fluid and destroys eye cells and tissue in minutes.
I would like to read what PPE is required and when, where have you found the regulations for PPE?
You wrote about rental propane tanks used for transporting anhydrous ammonia. I haven't heard about that, good tip. Where did you hear about the rental tanks being returned after transporting anhydrous ammonia. I would have thought the people who fill the tank would have an interest in ensuring the safety of the tanks.
Looking forward to your reply.

All you have to do is go to the OASHA web page to find proper ppe requirements for this chemical. all msds sheet should have this as well. this item on the returned propane tanks is from a pass around email on a report sent via the Government grapevine.

Hey rocket scientist, Please quote the regs stating no ppe is required, if you can well my bad but I know for a fact you are wrong. But in the sporting fashion I give you this chance, so as they say, PUT UP OR SHUT UP!!!!!!
