Your employer is planning a job that involves working at height.
Put these in the order they should be considered, starting with the first.
Put these 3 steps in order.
AA. Reduce how far someone could fall and how badly they'd be hurt
BB. Avoid working at height if the job can be done another way
CC. Prevent falls, for example with guard-rails or a work platform
Show the answer and explanation
Correct order: B, C, A
B. Avoid working at height if the job can be done another way First. For example, do the work from the ground using tools with extending handles.
C. Prevent falls, for example with guard-rails or a work platform Second. If work at height can't be avoided, use equipment that stops a fall happening.
A. Reduce how far someone could fall and how badly they'd be hurt Last. Where the risk of a fall remains, use things like safety nets or air bags to make a fall less serious.
Explanation
Avoid work at height where you can. If you can't, prevent falls. Where the risk remains, reduce the distance and the harm of any fall.
