Crikey.

not a nice way to go......


An absailing rope and a point to hook it onto, might be handy
for the
future or even just a rope. At least it would give them a
chance of
descending relatively safely.

A rope might burn through. I think I'd prefer a parachute if the
tower
were high enough.

From my parachuting days, I seem to remember that the minimum
height
for a chute to open is about 500ft and that's assuming that the
chute
opens perfectly, which is not always the case.

You need a rope and an air brake, just attach to harness and
jump, the
rope should survive the few tens of seconds needed.

Its still a bit risky if its windy, then you need the rope to be
attached to the ground.

Would a bungi rope be practical (obviously a slightly advanged
one, in
that it's slowly breaks the fall) If you know the hieght would it be
that difficult to design such a thing ?


We obviously need the HSE to step in and regulate these highly
dangerous
structures.

What about metal rungs going part of the way down (say20ft) and a
little
covered safe area where 2 people can sit and wait for rescue?

Makes more sense to have a fire proof rope and a gadget
that allows a controlled rate of descent on that rope.

Mechanisms can freeze up in icy weather.

In practice that is easily avoided by the mountaineers and riggers.

I still think that the best and safest/cheapest way, is to have metal
rungs so they can quickly climb down a short distance to a small covered
cubby hole where they can clip themselves onto until they are rescued.
They'd be away from the smoke and a small metal cover over their heads
will protect them from any falling bits. I'm sure it wouldn't cost much
to equip all of them like that.
There'd be no mechanisms to possibly fail either.


There are already access ladders and they failed.

I still think one of these would be better

If its windy you need a guide wire putting in place before you start
work so you don't blow around into the tower.
