Use the ladder but take care when stepping over the position of the missing rung

45 / 47

What is the main danger of leaving someone who has fallen suspended in a harness for too long?

They may try to climb back up the structure and fall again

It is a distraction for other workers

The anchorage point may fail

They may suffer loss of consciousness and further injury

46 / 47

What is the main reason for using a safety net or other soft-landing system rather than a personal fall-arrest system?

Soft-landing systems are collective fall arrest measures
