Well I never, I have never heard of a telescopic ladder before
If it is any good it would be great for occasional access to a flat roof, or climbing over a wall or fence.
That accident is one of those types that I'll bet all of us who use ladders have come close to on the odd occasion.
As he was coming down he misjudged his footing and his foot slipped off the rung, taking him by surprise, maybe because of the fact he had that duster in his hand it prevented him from keeping hold of the ladder and down he went.
Because he wasn't holding onto the ladder correctly, one hand would have had a much tighter grip than the other, the hand holding that duster would have come away, his body twisted slightly and he was unbalanced....thud!
I've had this one happen to me on many occasions over the years, maybe a wet foot that slips of the rung or something, but I've always climbed correctly, your foot slips through the rung a...er...foot or so
but you recover safely.
Dread to think what would happen if you were 20ft up a ladder and the same thing happens and you suffer the same fate as the muppet in the clip!
Or your foot doesn't come out from between the ladder rungs and you are left dangling 20ft up a ladder with a broken leg...and all your weight suspended from that broken leg
Thats the trouble with getting older, you can visualise the consequences of an accident.
Now, if my foot slips of the curb I'm going, "Phew...
Could have done myself a real mischief there...hope I haven't put me back out
"
Right, time to get to work, going to stay well within the speed limit and I won't break the 2 second rule (I'd be a fool to do so
) Maybe I'll make it a 4 second gap just to be on the safe side :
