The nature of any electrical hazards, fall hazards, and falling object hazards in the work area 2. The correct procedures for dealing with electrical hazards and for erecting, maintaining, and disassembling fall protection and falling object protection systems 3. The proper use of the scaffold and proper handling of materials on the scaffold 4. The maximum intended load and load-carrying capacities of the scaffolds used 5. Any other pertinent requirements of the subpart [OSHA 3150 Scaffold Guide, Sec 5, p.51] **Retraining Requirements** Retraining is required when: 1.
