Fragile surfaces (roof lights, cement sheeting, slates and tiles, glass etc)

Carry out works from underneath from a suitable working platform wherever possible.

If work cannot be done from underneath and access is needed to the topside of the roof, consider use a mobile elevating work platform (MEWP) that allows people to work from within the basket without standing on the fragile surface.

If access onto the fragile surface cannot be avoided, install robust perimeter edge protection, and use stagings/platforms with guard rails on the fragile surface to spread loads. Seek specialist advice to establish the surface will withstand loads to be introduced onto it before access is attempted.

If the above is not possible, birdcage scaffolding, or safety nets should be installed underneath by appropriate competent persons.

Proprietary covers may be available to prevent someone who is passing or working near fragile material from falling through.
