Watch this video and learn what not to use to put out a grease fire.
This is a great video. Everyone should watch it and take heed. When I was stationed in Charleston Navy base at the Fire Fighting Training school we would demonstrate this with a deep fat fryer set on the fire field. An instructor would don a fire suit and using an 8 oz cup at the end of a 10 foot pole toss water onto the grease fire. The results got the attention of the students. The water, being heavier than the oil, sinks to the bottom where it instantly becomes superheated. The explosive force of the steam blows the burning oil up and out. On the open field, it became a thirty foot high fireball that resembles a nuclear blast. Inside the confines of a kitchen, the fire ball hits the ceiling and fills the entire room. Also do not throw sugar or flour on a grease fire. One cup creates the explosive force of two sticks of dynamite.
