I spent a year at a local fertilizer plant when I was young
Worked a lot with anhydrous. Even did custom application for far
This thread just brought back memories. I’m looking right now at a 50 year old scar on my wrist that was nothing more than a scratch that I got working on a tank. Took all summer for it to heal
I worked with it also. We piped it from tanks to heat treat furnaces using extra strong fittings and seamless pipe schedule 80. I had the misfortune of getting gassed a few times, very scary just a whiff was enough to gag and make you puke. burn your eyes and skin. Nasty shit.
