Interesting article, BUT...
I disagree with this:
"I've recently been looking at water-fed pole work, and I estimate that over 90% of it does not comply with UK statutory law"
Sorry but that is just rubbish. You go on to say that this is because of the hazard of falling objects:
"Regulation 10 of the working at height legislation covers falling objects, and makes it clear that in order to fully comply with the law, a safety zone should be demarcated, ideally including cones, tape or barriers.
There should also be clear signs indicating that work at height is in progress, and that there may be a falling objects hazard. Such barriers and signs are frequently missing."
Partly true, but you omit the part where the regulations say that these measures should be taken if they are "reasonably racticable". IE in proportion with the risk, as assessed in a risk assessment. A window cleaner cleaning windows over a pavement for 20 minutes would not be expected to erect barriers and demarcate a safety zone, because its simply not reasonably practicable, and the risk of the pole falling is so small that it would not be justified.
The regs actually say that you have to take "suitable and suffient steps to prevent, so far as is reasonably practicable, the fall of any material or object."
Common sense would say that holding onto a pole (ie not leaving it unattended while extended) would be suitable and sufficient to reasonably prevent it falling on someone. Marking out barriers etc, is way beyond that. Personally I'd be more than happy to justify this to a H&S inspector if one asked me.
If you're saying that the risk of falling poles does justify such extravagant measures for the short time threy'd be needed, you'd have to back it up with statistics showing how many injuries had been caused by falling poles, which of course you can't because no such statistics exist. (which itself is a true indication of just how small a risk this is).
Personally I've never heard of anyone being injured by a falling pole.
