aerial cableways and fixed objects such as ramps, platforms and

chutes.

enclosed or fenced.

devices that prevent inadvertent tipping.

8.1.5. If workers have to pass from conveyances to supports,

devices to enable this to be done safely should be provided on

both.

supports, working platforms complying with the requirements of

section 3.2 should be provided if necessary to prevent danger.
