No Sky abide by the law, try and cover all the risks, wear a helmet & secure the ladder as per WAHR, have correct training, and walk away when job cant be done safely. Ladders are still safe if used correctly, and for short periods.

The problem is often that window cleaners become complacent. They think that because nothing happened the last 10, 20, 100 or 200 times they done that, no accident or fall happened so therefore it's safe.
That is why it's so important to understand what 'risk' actually is as opposed to what some 'think' risk is.
It's like those that drive too close to the car in front which is so common place. They think that because they've being doing that for yonks without an accident that the rules about a safe distance from the car in front don't apply to them and are not needed because they know what is a safe distance from
not having having an accident.
