Another anecdote....what just happened in the kitchen:
Sometimes I get up and stumble into the kitchen in the pitch
black to make a coffee first thing in the morning.
So I don't wake the kids and wife, I leave all lights off and make
the coffee just by the light coming from the electric kettle neon.
(everyone knows us astronomy types and their aversion to bright
lights, right?
The kettle was about half full of water from it's weight.
Well, in the darkness I switched on the kettle not realising that
the hinged plastic lid on it's top wasn't fully clicked down.
When left like this the kettle takes ages to auto-click itself off
when boiled and sometimes doesn't.....first mistake.
While it boiled, I left the kitchen (second mistake) to switch on IIS
and check the latest messages and pop my head outside to see if it was
cloudy.
I forgot the kettle and got absorbed in reading a few things on IIS.
Next minute, I heard a low volume 'beep beep beep' coming through
the baby monitor in my daughters room.
I thought it was one of the kid's digital watches or toys going off
and went to investigate it so it wouldn't wake them up.
I found the kitchen full of steam, the kettle still boiling and the
lid of the kettle half up stopping it from turning off.
The kettle was almost boiled dry!
The passageway was full of steam and the fire alarm was going off
BUT AT VERY LOW VOLUME....almost just a clicking sound.
The battery in the alarm was fine, it seems that steam had disabled the
alarm from making lots of noise.
So I shouldn't have left the kettle.
Kettle may have caught fire and the fire alarm not alerted me.
Stupid fool I am!
