    I can understand that. It's probably that they don't want anyone under the impression that it's safe to be in there when the system is activated.
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

    It's not too bad, unless the room is on a raised floor, and you're under it. Both gasses are heavier than air, so the hold you breath and run idea is okay. The thing to remember is to close the door when you get out. Wouldn't work for my server room, it has a big ass vent on the door. The thing to remember with water bases systems, is the water is usually just sitting in the pipes. Those pipes are usually iron. So the first hundred gallons or so is really nasty stagnant rusty water.

    Something that removes the oxygen from the room is going to put out a fire faster than water, and not be as much of a mess to clean up, so your recovery time is going to be a lot less.
    For a full fledged data center I totally agree.

    I was thinking more of the couple hundred square feet room on one floor of a building housing at most a few dozen machines....
    I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.

    I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.

    Just doing some quick research I found this to be interesting for small installations:

    Fireraser fire suppression system for small spaces and in-cabinet fire protection.

    I'm going to check on pricing. We only need to cover 200sq feet, so it probably wouldn't be too bad. But we may end up getting multiple units for things like our PLC cabinets, VFD's and such.

    Water hitting 480V three phase is never a pretty site.

    Fixed that for you.

    Mine would also be correct, since the site wouldn't be too pretty after the resultant short caused them big capacitors to explode.

    Didn't I tell you about the 480V 2000A lines that shorted out during the summer? We had smoke pouring out of manholes and the switchgear room was filled with smoke. Trust me, the site wasn't pretty.

    So you're saying that site wasn't a pretty sight?

    Pretty much that's what he's saying but what a sight it was.

    To prevent fire just lower the oxygen level to 15%. Standard air is about 21% oxygen. At 15% you can't have fire, but is safe for humans.

    When I was in the military all our equipment was in mobile vans. If it started buring, just jump out, 31 seconds, 32 seconds, didn't matter, whatever you felt like

    I heard David Carradine was doing some top-secret research in that area before his untimely death
