I believe Turtle is referring to the very old sulfur Dioxide Refrigerant S02

Ammonium Sulfide (NH4)2S is also very deadly, but I don't think it was used
as a refrigerant. Ammonia, NH3 was, and is also very potent poison.
when I was a kid, many moons ago (over 50 years ago), I opened up a
compressor system from a very old refrigerator or freezer case; it had a
reciprocating compressor belt driven by a motor and had flare fittings. When
I cracked the fitting open: Wow! I will NEVER forget that! I was able to re
close the fitting and stop it. Man, that was the most stupid thing I ever
did, but I was a kid.

I agree with the majority he NO! remove everything possible without
compromising the sealed system.

Before you cut know that it don't have SO4 in it. If the SO4 hit the air
it will make vapor like H2SO4 which will kill you if you breath the
vapors. Now if it is in a basement with no vented area. You a goner in
just a few seconds.

READ THE TAG TO MAKE SURE IT'S NOT SO4 IN IT.

Isn't SO4 Ammonium Sulfide? Has SO4 ever been used as a refrigerant in
consumer products?
