Why is lone working generally prohibited for height work tasks?

A. Without another person present, there is no one to observe the work, raise an alarm if something goes wrong, or begin the rescue plan promptly

B. Lone working is only a concern for night-time tasks

C. It is purely a union-negotiated rule with no underlying safety basis

D. It is not actually prohibited — height work is fine to do alone if the worker is experienced

A. The deck area should be cleaned and the slope/level checked against the MEWP's rated operating limits before deployment; if outside those limits, a different position or method should be used

B. Proceed and rely on the MEWP's outriggers to compensate for any surface condition

C. Proceed as normal — MEWPs are designed to handle uneven surfaces automatically

D. Proceed but instruct the operator to move slowly

A. No — the worker should receive a specific briefing/familiarisation on the rigid rail system's traveller mechanism, attachment/detachment points, and any system-specific limitations before first use

B. No, but only if the worker has never climbed a mast before at all

C. Yes — all fall protection systems work the same way functionally

D. Yes, provided the harness is the same brand as previously used
