Basic Information
August 10, 2008.: A fire and several huge explosions occurred at a propane depot in Toronto, Canada.
Although it's not obvious from the video, this sort of facility is prone to BLEVE events (Boiling Liquid Expanding Vapour Explosions) in which a small leak of burning material can turn a storage tank into a fuel-air bomb - which is the likely cause of the massive explosion. The case study for such things is usually the San Juanico disaster of 1984.
