Falls from heights prevention - Hierarchy of control
You can’t undo a fall, but you can prevent one. If you’re a builder, subcontractor, site supervisor or employer, it’s your job to keep people safe. WorkSafe expects the highest level of fall prevention to be in place.
Level | Control | Example |
---|---|---|
1 | Eliminate the risk. | Work on the ground. |
2 | Passive fall prevention devices. | Guardrails, scaffolds, EWP, safety mesh. |
3 | Work positioning systems. | Rope access, travel restraints. |
4 | Fall-arrest systems. | Harnesses, catch platforms. |
5 | Ladders/Admin controls. | For short, low risk tasks only. |
A mixture of controls is usually required - not just one.
This video will help you chose the right level of fall prevention for your work.
