Posted By Richard Perry I'm looking for clever solutions to access along the valleys of an asymmetric northlight roof. Glass on one (steep) side, Corrugated asbestos cement on the other. Gutter is strong and would bear a load. No access for cherry pickers and we'll need more than just fall arrest.

Posted By Ken Taylor This is probably the sort of question that is impossible to answer at a distance. Presumably the glass won't be safety glass either. I would expect that some combination of barriers (temporary or permanent), fall-restraint with fixed safety line and anti-slip flooring to the gutter may be the way forward. We have a number of interesting gutters on our historic buildings and have had to revert to various access solutions - all very site-specific. Inviting a specialist company to visit and put forward proposals has always proved invaluable but you do need to discuss these with the operatives concerned who will be working there.

Posted By peter gotch Richard, The HSE guidance to which you refer shows a proprietary system which spans across both slopes. In terms of natural lighting, particularly on the glazed side, the same principle could be extended to providing protection via a multiple guard-rail frame Someone would of course need to check that the purlins or astragals supporting the glazing and roof sheets are suitable for any additional loading. Presume that the roof predates CDM - otherwise perhaps you might ask the designers why they have not facilitated your compliance with Reg 13 of Workplace (HSW) Regs perhaps pointing out the implications of Section 36 of HSW Act to them and the words "Professional Indemnity Insurance".
