That looks like the cover off of an Infra-Red Heater.
Ian,
I'd like to make something a bit clearer about de-energising a house or any other installation that may be part of a fire.
As a Faultsman and Fire Officer, the need to make the installation safe, needs to be wieghed up with the risk to people that could be still trapped within the building.
We don't needlessly cut the power to a building unless there is a
real risk of electrocution of our staff (FF's).
Also, I will add, that water as it is, is slowly going "out of fashion" as far as Fire extinction is concerned.
Water causes a LOT of secondary damage not associated with the original fire and it is looked upon in this day and age as un-profressional to spray large amounts of water at smoke only.
Compressed Air Foam is the tool of the modern Fire Brigade.
Put in the right places,it gives a 600% better result than water (when backed up with a Positive Pressure Fan) and less property damage.
Fire-fighting is a lot smarter than it used to be.
The Jet nozzle is proof of that.
