Has anybody come across any guidance on the maximum pitch of site temporary stairs?

We've got a job with really restricted space in which they want stairs but they are ending up at 60 deg with little left on the going. I know Part K gives guidance for public and resi - but aren't these for permanent stairs??

The irony is, if we are governed by Part K then I might as well forget the stair and put in a ladder. But even a 60 deg stair has got to better than a ladder surely?
 
Yes, pretty sure there's some guidance in 12811-1 might even be replicated in TG20 but would need to check.
 
Should have thought of that - yeap its in 12811.

Some formulas to jig around for teh goings and rise but essentially must be less than 55 deg.

Thanks all.
