Final answer:
Employees performing work from a scaffold must be trained on proper use of the scaffold, maximum load capacity, and electrical hazards.
Step-by-step explanation:
Employees performing work from a scaffold must be trained on several aspects to ensure their safety. This includes:
- Proper use of the scaffold: Training should cover how to set up, inspect, use, and dismantle the scaffold correctly.
- Maximum load capacity of the scaffold: Employees need to be aware of the weight limits of the scaffold and not exceed them.
- Electrical hazards: Training should address any electrical hazards present, such as power lines near the scaffold, and how to work safely around them.
Therefore, the correct answer is option 4) All of the above.
