I think that all of us on this forum would not recomend ladders being banned,
  not only our industry but others would be effected. The issue lies in the safe
  use of ladders, I don't know about you guys but new houses today are not built
  window cleaner friendly.
  When you are having to do windows from the side and often reaching out this
  is when I consider ladders to be a risk. When you buy a ladder there is always
  stickers indicating safe use of ladders, and I'm sure including myself we have 
  crossed that barrier in our time.
  Hence since using WFP I have found this a safer alternative, and like most on this
  forum we were dubious about changing over. In the end I'm glad it does the 
  same results as trad provided you use the tools right. 
  I want to expand like most of us on here but the last thing we want on our minds
  is the death of a employee, another reason why I went WFP.
  Yes it has it down sides like trad but I feel a lot safe as well as my staff.
   I don't think there is anyone on this forum who has never had that filling your
   pants feeling as your ladder moves, now it's that wet feeling with WFP.  
 
   Each to their own but I was as stubborn as David-St Ives and I changed and it's
    like a weight off my shoulders. 
    My advise is try WFP but go the DIY route as I feel some company's rip us off,
    I'm quite willing to give anyone some money saving tips.
     Just remember " YOUR LIFE IS IMPORTANT FOR YOUR FAMILY"
