As a result of the lovely weather conditions we have been experiencing recently, we have had a number of enquiries regarding working from ladders in windy conditions. The type of work we are talking about is generally gutter work at around 2-storey level. We currently use the 'ladder fix' and restraining harness system. Appreciate that a 'local judgement' will obviously be important but was wondering if anybody has any rough 'rule of thumb' method that they use that doesn't involve the use of an anemometer. Have spoken to suppliers of 'ladder fix' but they don't have any specific guidance.

The simplist anemometer is made of a tube with a hole in the bottom and a plug you turn the hole towards the wind and it will drive the plug up the tube giving you the wind speed cost around £5.
Or you could get yourself a copy of the Beaufort Scale this is the famous gale force 1,2,3 etc and is a visual scale layed down by Admiral Beaufort as an aid to sailors.

Get the anemometers and Mobile elevating Platforms, (MEWPS), or cherry pickers to you and me, have a wind speed upper limit. I cannot remember what it is, but if you can find a hirer, or manufacturer they'd be able to tell you and then use it as a guideline. However, the old fallback "and do a risk assessment" is perhaps better advice.

Interesting thought - Who is going to ascend the ladder to check the speed at gutter level? As a rule of thumb first remember that alloy towers at this height are restricted to 25mph and this, if I remember the Beafort descriptors, is when medium size branches are beginnning to sway in the wind.
I personally would be sticking at around 20mph good as I know the ladderfix is in most situations.
