This is one of those things that you learn over time unfortunately. Unless you happen to have friends with experience on the topic and can tell you what to look for or help move into action. Otherwise vidoes like this are helpful(hopefully this guys was able to save some of his plane). In this case, the large flame doesn't really faze him and I don't think he realized what was going on. With CO2 you can hit it when in doubt and err on the side of safety whenever you see smoke that is out of the ordinary(harder with diesel) or flame that is out of the ordinary. I've had some experience with hot/wet starts and seen a few at events that were handled well. One thing I have never seen and never hope to see is a collapsed pipe. Not sure what that's like.
