Go straight for a van mount Ionic's if you can. Top Systems and the only ones that fully complies with the Road Traffic regulation to a modification. http://www.ionicsystems.com/english/crash_testing.html
There is no Road Traffic Regulation concerning a modification, you're making that up. Its a spoof (or at least the complying part!!!). The link you have provided..
http://www.ionicsystems.com/english/crash_testing.htmlconcerns the fitted Ionics system having accreditation from "Thatcham Research". As long as everyone understands that "Thatcham Research" is a private limited company. It actually carries no more kudos than me telling you i am or am not a member of the Window Cleaners Federation, The Guild of Window Cleaners or the Scottish Window Cleaners Association. It just means someone took the trouble to say its ok and they advertise the fact to the max. I'll bet it cost them a few bob too as accreditation from Thatcham aint cheap.
And i love this too.............
As a result, we remain the ONLY supplier of water-fed pole equipment to be awarded the FMVSS-208 certification.And that certification is an injury risk assesment based on dummy responses !!! Sounds good though, dunnit?
I make my own risk assesments up on an as an when basis as i go about my work, as do 90% of us here.
I also train window cleaners upto international standard MIKCAM 123 ISO , thats pretty much required for anywhere i work but i'll bet you never heard of it !!
