why would you like to know them cowboy lol ( sorry that name makes me laugh)
Because if there were any (which I highly doubt) they would likely say:
"Number of injuries caused by falling poles : ZERO"
The point being that this isn't a significant risk, and certainly not one that would require courdons to be placed. Doing so is simply disproportionate to the risk involved and would never be considered 'reasonably practicable'.
Andy Willis and his crew are clearly coming up with idiotic statements like 'over 90% of window cleaning with waterfed poles doesn't comply with the law' to scare people into coming on their training course, and continue claiming money for the government for each one. His whole business depends on this so of course he's going to try to scare people into thinking they need training any way he can.
If you can't see that his only objective is to get people to do his course then you are naive. If he had the window cleaner's interests at heart, he wouldn't want to see us burdened with unnessassry regulations, let alone be interpreting them to wrongly imply that we need to do something the law doesnt require.
