For safety construction of scaffolding system, you can't do these things as follows:

1. Climb on any portion of the scaffold frame not intended for climbing. Always use a fixed ladder, internal access stairway or built-in ladder to access the working platform. There should always be a handhold above the scaffold platform. Never climb with any materials or tools in your hand, they should be hoisted up to the scaffold separately.

2. Use the scaffold if it appears that it is damaged in any way, has been tampered with or if there are components missing such as planking, guardrails, toeboards, debris nets or protective canopies. Notify a supervisor immediately to get the scaffold in proper working order and inspected by a competent person. Never tamper with or attempt to repair a scaffold unless you have received training in scaffold erection.

3. Overload the scaffold. Proper training includes being informed of the maximum intended load of the scaffold you are working on as well as its load-carrying capacities. In most instances, scaffolds should be capable of supporting at least four times its maximum intended load.

4. Walk on scaffolding planks covered in ice, snow or mud. Worn wood planking can also be extremely slippery when wet. All snow, ice, mud and other debris such as wet leaves should be thoroughly removed before using the scaffold. You should also avoid using a scaffold during adverse weather such as heavy rain, sleet, ice snow or strong winds.

5. Leave anything on the scaffold at the end of your shift. This includes any building materials or tools that you may have been using on the scaffold while you were working. These items could potentially be blown off the scaffold or cause tripping hazards for the next person using the scaffold.

6. Use boxes or ladders to increase your work height. If you can’t reach an area you should request that your supervisor has the scaffold platform raised. Don’t use stilts unless the guardrails on the scaffold have been extended to a height that is equal to the height of the stilts.
