Posted By Lwood You can see a copy of the standards at http://www.scotland.gov.uk/library2/br/brs-04.asp The fact that it is a glass stair is not relevant other than the factor of 'modesty' for those workers wearing skirts/kilts. There is a slight aside on the issue of slips but that would be the same if it was a marble or tiled stair. We have used BRE (a charitable trust) in the past to provide a report on stairs and slips.

Posted By martinw PhilP have a flick through approved document K for the general stuff regarding stairs. BS 5395 Part 2 1984 Table 2 Requirements for the design and use of Spiral Staircases may also be of use if the stair is spiral, otherwise K should be enough. There are loads of commercial websites regarding glass staircases, so should be easy to find. The aspect about being a gap which someone could get their foot through sounds a bit dramatic, but if true could tax your risk assessment. From memory, the maximum gap allowed is 100mm for between balustrades, but I do not know if this applies to the gap between the edge of the stair and the fixing. I imagine that the same principle would apply but cannot be sure. http://www.pilkington.co...nd+codes+of+practice.htm the above gives all of the relevant british standards for the glazing, as I imagine that if the stairs are glass, so will the balustrades be, with the requirements which go with them too.
