I thought I would post these 2 fatal accident reports concerning window cleaners. Perhaps we can use our networks to raise the awareness to the hazard when we see a window cleaner at work.

Very sad for those involved. I wonder how common this is, are we really unlucky in seeing two in a year or is this typical ?
If it is a common accident perhaps a technical solution, such as an insulating break in the pole would be worthwhile promoting to manufacturers of such kit.
The chaps and chapess that do the windows here actually use de-ionised water, so the water conductivity is quite poor - there is an pump and ion-exchange resin in the back of their van that softens the tap water - and that indicates the cartridge needs changing, when conductivity exceeds some value in the range around 1.0 µS/cm. Of course they then add detergents to the DI water, so no idea what that does (well some idea… but its not quite that sort of soap of course) .
Oddly I have used kit with an HV power supply that used a window cleaner style resin cartridge in it to keep the cooling water conductivity down as it flowed over both metal live bits, as well as metal earthed bits at the other end of long hoses.
The promotion of less conductive tools and detergents cold perhaps be second claw to the pincer as well as a simple “look up - look out” campaign.
