Banning ladders would actually make our job more dangerous.
Explain?
OK heres one:
I do a school in my area, it has a row of windows accessible from a flat roof. There is no way to reach the windows from the ground via a telescopic pole.
The school is fitted with fixing points for a ladder and a harness wire on the roof.
The flat roof has 2 stages so it would be impossible to access via a cherry picker or platform.
The only alternative I can imagine would be to dangle from a rope tethered to a helicopter.
Not practicable.
The safest method according to the risk assessments is using a chuffing ladder.
Otherwise we are either:
1. Dangling from a helicopter
or
2. Using some other as yet un-devised, un-tested method.
There is no reason for us not to use ladders. So long as we're not going to be silly billies about it.
