And to think you could have just set it outside 2 months ago and made it solid :)
Seriously, I think Noble Co would have your answers. They make a lot of premix, concentrate, both flavors, and the special Hastings style for big heads in cold places. glc -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Chris Cahill Sent: Tuesday, April 21, 2009 3:46 PM To: [email protected] Subject: RE: antifreeze combustibility? I took some 50/50 and added dry ice to bring it down to -37. Definitely slushy not frozen though it should have been. It would come out of a sprinkler head but not terribly effective. Think milk shake from McDonalds after about 20 minutes at room temperature. Chris Cahill, P.E.

Todd and others, I've heard of contractors using 100% anti-freeze on small systems 'cause " the guys aren't good at math and what harm is it?" I pointed out that freeze point rises beyond 40-50%. The flammability issue didn't occur to me. C.

This all begs a lot more questions: 1. Has this scenario be reproduced in a lab or other controlled environment? Full scale testing? 2. How does concentration impact reaction? 3. Was the antifreeze a pre-mix solution or mixed by the contractor? 4. Does the antifreeze and water separate over time? 5. If this is an issue, why hasn't NFPA been more proactive? 6. Glycerine vs. Propylene Glycol? 7. Does is react to flame or only a heat source? At 03:02 PM 4/21/2009, you wrote: >Members, > >A settlement was reached in this matter.
