Back in the early 60s, my G-ma toasted the wall in the kitchen, above the stove and under the hood, with what was described by the witness (my mother) as "...the greasefire of all greasefires!!" (Exact words)
The insurance company SUGGESTED that the backwall be treated to a serving of stainless steel backing that went along the width of the stove plus 6" each side, the taper/slope inward, near the top, into the overhead-directly-through-the-wall vent/hood.
That was then.
Now?
Ansul is a good start.
As for monitoring?
Considered a bell around Ed's neck? Not to confuse him with the cats around the place...
