I'm not sure if this is really an appropriate question for here, but
I'd be grateful of advice!
There's a flight of external stairs that people have tended to fall
over on over the years. I've suggested better grip in the wet might be
a good idea and, as a result, an exterior paint, mixed with sand, has
been applied, giving a much better grip.
People still fall over - the stairs aren't even outside a pub, so
that's not the explanation!
I had somebody criticise some other stairs, saying that the risers were
too high and might be dangerous, so I wondered if that might be part of
These stairs have a railing, but the riser hight is 17cm and the tread
width 28cm. I gather, from a brief look at things, that 15cm is a good
size for a riser. Is 17 cm too high? Would it make sense to put an
extra stair between each of the current ones giving 8.5 and 14 cm, or
would that make it worse?
Not everybody using the stairs is in the first flush of youth, which is
part of the problem, I know. They have a railing, on the right hand
side going down, but they are over three metres wide. Should they have
a railing down the middle? Is the height of the railing important?
