very easy to do that! you use the same equipment that you would if it was a side of a building!
full body harness and a fall arrest system! simples!
I was about to say, Cant you use absailing equipment. although ive no experience of this type of work i must add!!!
could, but cant move along that well, with the fall arrest system there will be a wire along the whole length of the building that a lanyard will be attached to that will side along as you move from window to window,
Which is the only way to do it. But will the initial cost of installing this and the annual inspection justify the cost of cleaning? (According to the local school who were considering installing this system to allow access to clean solar panels safely, the annual inspection and certification costs £450.00.)
Know what you're saying,
What would a law suit cost them if something happened?
A pub had to pay out nearly £300k for a death for a fall off the ladder.
The other way to look at it That 450 a year only works out at £37.50 a month, or roughly £9 a week, or even £1.23 a day. what cost do you put on someones life?
As for cleaning solar panels on the roof there are other fall arrest equipment that you can use that doesn't need all that, there are portable systems that can be taken up there for that sort of thing.
