I remember seeing a very enlightening video a couple months back that showed the effects of what this person did. The video was showing the dangers of adding water to a cooking fire leading to catastrophic results. Here's the link, http://www.youtube.com/watch?v=sZGzbd0IvUE. It doesn't surprise me that a confined area could or would explode in the way the news article points out. Regardless of previous lawsuits, the likely hood that the antifreeze solution in the sprinkler system helped propagate the fire is unlikely. Watching the video, it's not hard to ascertain that an oil fire that is incorrectly attempted to be extinguished with water can lead to disaster. This is where the fire community needs to step it up and continually and aggressively educate the public.
