7 steps

1. Ignorance: dont be lazy when setting up the scaffold, set it up correctly, dont cut corners.

2. instability: never move the towers when people of tools are up on it, never move the tower over unstable ground.

3.Exceeding the safe work height: never build the scaf higher than its suposed to go, there are different rules for different scaffold, also whether you are inside or outside, if outside consider the winds and what their going to do.

4. mountaineering: never climb up the outside of the scaff, there should be a ladder on the inside.

5. unsafe platform: always make sure your platform is set up correctly and safely. this means put together right, and set up on the correct flooring.

6: untied tower: always make sure the ladder you are using is tied to the top of the scaff, if not you shouldnt be using the scaffold at all.

7: overloading: never overload the tower with anything, people or tools. the safe work load is 400kgs with full scaffold.
