Bill,
Thanks for posting that link. It is interesting reading and I did go to a couple of the stores here that our Fire Chief recommended and they do not sell the Halon type any more. Mine in the kitchen, garage, and other places are so old that I am afraid they may not work. All I can find is the Triple type, dry something that is supposed to work on any kind of fire. Has a triangle and a couple of circles with A, B,& C inside them. A is in the triangle.
