(b) The nominal weight of each component, in kilograms.
(c) Instructions for erection, re-positioning and dismantling the perimeter protection screens.
(d) Guidance for the servicing and inspection of the equipment and the rejection of damaged components.
(e) Details giving sufficient information to determine–
(i) the maximum height of screens between connctions to the supporting structure;
(ii) the maximum freestanding height of screens above highest connection to the supporting structure;
(iii) the maximum horizontal distance the screens can span between connections to the supporting structure;
(iv) the maximum number of platforms supported off a screen and the maximum working load per platform; and
(v) the maximum load that can be placed on a loading platform connected to a screen.
(f) Maximum loads imposed on the supprting structure.
(g) Method of conncting the screen framing to the supporting structure.
(h) Method of safe lifting of screen assemblies by mechanical devices.
