    "Refrigerator repairman loses part of arm in explosion"

    http://www.modbee.com/2014/05/16/334...F1571%2F&ihp=1

    I'm really curious to hear the results of their investigation. I don't think a standard refrigerant cylinder can do that. The fusible plug would blow first.

    Here is one from a few years ago.

    I was on a nearby building (Blue Grass rd) when I noticed the news helicopters hovering over the Blvd.

    Wow.

    These are both stories we just don't want to hear. For the sake of the rest of us though, it'd sure be helpful to know what caused either one.

    In my post #13 here> http://hvac-talk.com/vbb/showthread....gen-pro-s-only

    ...they knew what had caused that. That was outright negligence in observing a fundamental safety practice...because the right tool (a regulator) wasn't available, so he tried to shortcut the procedure.

    That incident occurred back in the late-sixties or early-seventies.

    There was no published info regarding any investigative outcome for the one I was near. I surmised that he might have allowed his DOT 39 tank to become pressurized, and may have been killed when the disc came out, like a shotgun blast.

    The restaurant never reopened. It was bulldozed a few months later, and now it is a part of the car dealership that was its next door neighbor.

    We were doing a remodel at a truck stop, I was installing a condensing unit on a six evaporator walk in cooler. It was in the middle of January and the temperatures were in the single digits that morning. I had a new 30 of R-22 still had the seal on the valve. The drum had been sitting in my frozen truck all week and I needed the whole 30 lbs. So I took it over to the kitchen mop sink and stuck the drum under full hot water. It was less than 20 seconds and the disk blew off the top of the drum laid my hand open and I shot off running out the back door with a whistling drum of refrigerant. When I got outside I tipped it upside down to shut it up bandaged my hand up with electrical tape and grabbed my thermometer. I found the discharge temperature at the fixtures was 187 F! Went to the water heater to find temp control all the way up to 205! and TNP valve was leaking pretty good on temperature I measured that at 200.
