who says wfp is 100% safe? :

the possibilities to meet your demise are still there:
touch an electrical overhead wire with the pole and zapp your dead
trip over the hose and into the path of a bus and smash your dead
walk backwards to get the lower half of the windows and fall into the canal and splash your dead. (maybe

)
and there are ways of killing others too with the thing, drop the pole on someones head and kaboom they are dead.
(yep i just watched one of the old batman shows

)
but thats the point.....its still safer than ladders in the RIGHT hands....untrained folk are just as a liability with the wfp as the guys on the ladders untrained.
who would you rather have work for you.....the untrained wfp guy or the fully trained ladder guy?
wfp is the way forward for any dangerous heights and angles, no doubt/no dispute, and most of my work is wfp due to that reason, however ladders still have a place in the workplace in my opinion.
