ITS TIME LADDERS WAS BANNED FOR WINDOW CLEANING
Whilst the case you point to is tragic you have to acknowledge there are risks in all occupations.
Your statement is like saying let's ban cars because people die every day whilst driving. We should all use public transport.
When someone chooses a career they consider the risks beforehand and choose whether or not to take up that career with it's risks. I'd rather be a window cleaner using ladders anyday over some other trades.
As with all other trades, whenever I take on a new job I do a risk assesment and work to minimise any risk to myself and others. If I think any part of the job is too high a risk then I don't do it.
I've done this since long before the HSE started telling everyone what they should and shouldn't be doing. That said I think much of what they say makes for a lot of common sense and are excellent guidelines.
As for a blanket ban on window cleaners using ladders though, I think it's very wrong. If a person doesn't want to use ladders at all, then he/she should only choose work that they can do without them. If they've got no problem using ladders safely, as many of us don't then we should be free to accept work that requires use of a ladder as long as we are prepared to carry out proper risk assesment and any risk involved is minimal.
