Many years ago I had two weeks of marine firefighter training at Texas
A&M. When we studied BLEVE's, (Boiling Liquid Expanding Vapor
Explosions) he told us a good rule of thumb about such fires. "Hold
your thumb up at arms length and close one eye. When you can hide the
entire event behind your thumb, you are far enough away."


That works well for telling your wife that you just bought a new tool also.
