More Fire Safety

Sometime after my earlier fire-safety post, I received an email with this video about how to properly extinguish a grease fire. I'm posting it here (and yes, I vet all email forwards on Snopes or similar) for further dissemination.

Here's what happens when you try to extinguish such a fire with water- the water, being denser than the oil, sinks to the bottom of the pot where it instantly becomes superheated and vaporized. This newly created steam rises up with intense pressure, blowing the burning oil up and out, filling an enclosed space with a fireball. Different but similar results occur when trying to use sugar or flour to extinguish the flames.
