Fire Safety

So does anyone know what to do when you have a grease fire? Well there is the standard thing to do... cover it up with a lid or something...but what it its coming from the inside of the burner?? ha ha well I learned the hard way. Last week Austin and I had the missionaries over for dinner...well I was making chimichangas which you deep fry and then I was making homemade tortilla strips...I threw all the tortilla strips into the oil at the same time and it started to overflow onto the burner. A couple min later I look over and there is a huge fire coming from the stove... well the missionaries hopped up and one told me to throw flour on it...and IT WORKED. So if anyone out there has a grease fire and are not sure how to put it out, just throw some flour on it! Ha ha.
