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?
