Fire extinguishers: smoke, fire, and kitchens

Wouldn't do for proscribed equipment, I'd think, as it's a stopgap. But then it's the price of a dinner with drinks....

I'd consider it the equivalent of a bucket of water or a hosepipe near a bonfire: prudent, a stopgap, not enough in some cases, but might just save your ass. And these work automatically, and are small enough that a "nuisance alarm" is a nuisance and not a catastrophe.

A residential sprinkler system that goes off unattended will flood the place eventually, possibly causing more damage than the bit of heat that set off a sprinkler head.

Then just keep moving it until it no longer goes off.

And social housing tenants who don't like where they live, are not above setting off sprinklers deliberately, which could cost £thousands in a tower block.

One brand of these was Kingston Fire Cable - I remember them strung across the boiler room when I was at school.

Given that I can find no reference whatsoever on google, I presume these were long gone before the Internet.

It's hard to get those asbestos-cement boards these days!

There are modern equivalents that sense insulation resistance that changes with temperature:

FyreLine Analogue Linear Heat Detection cable is constructed using a pair of copper conductors coated in a temperature sensitive polymer whose resistance changes as a function of temperature. A calibration resistance (white) and average ambient temperature sensor (red) core are twisted with the two original conductors. A foil shield, outer sheath and optional protective coating is extruded over the twisted cores.

We always used to have an asbestos simmering mat like thise

many ovens have a drip tray that will serve

indeed - or like, my maternal grandmother (born 1889) had much practice :)

And they don't work well unless the top of the pan is flat with no basket handles sticking up.
