[ABN 505]

I was inspecting a Heat treating furnace once that used nitrogen for atmosphere, I had shut off the valve and locked it out but the valve was bad and was leaking. Within a minute of entry I found myself blacking out, I was able to give a last strength push and fell out of the vestibule before I passed out. I would have been dead within another 2 minutes. Scared the shit out of me. The next day I went out and bought a thousand dollar monitor system.

Yeah, NASA has lost a couple of people in nitrogen-purged rocket tanks that way. They black out so fast they don’t even know to call for help.

Damn near did the same ting to myself, was told the tank contained compressed AIR.

Well it wasn’t, it was CO2.

Was in a completely sealed off small boiler room after an abatement job, had my full face mask/PAPR on and was blowing out the burners on the boiler when I started getting stupid and making mistakes.

I realized that I wasn’t getting any oxygen and damn near kicked the door of it’s hinges to get out, to hell with the contamination, it can be cleaned up later.

Should have sued the company that supplied the “COMPRESSED AIR” tank but was just glad to be alive!
