Stove Top Firestop is a product that was just brought to our attention by Capital Insurance Group, one of our most excellent insurance companies.  Part of the plug has to do with limiting or preventing costly insurance claims but obviously home fires are also a huge personal safety issue.  Stove Top Firestop is a fire suppressant in a can which attaches magnetically in the vent hood over your range.  In the event of a flame (not just a little smoke but more like a grease fire) the can releases it's contents and voila!  No more fire.  The flame must actually touch the bottom of the can for the contents to be released as you certainly would not want these things ruining your dinner every time you desire something well done.    It appears you need 2 cans for a 4 burner range.  Since it is magnetically attached it is ultra easy to install.  Even I can put it up!  So, help yourself, your family and your California home insurance by considering the purchase of the fireman in a can, Stove Top Firestop.  Google www.stovetopfirestop.com for more info.
