How far should scaffolding be kept away from electrical lines?

The correct choice emphasizes maintaining a safe distance of at least 10 feet (3 meters) from electrical lines, or adhering to local regulations if they prescribe a greater distance. This guideline is essential for ensuring worker safety, as electrical hazards pose significant risks on construction sites. Keeping scaffolding at this distance reduces the likelihood of accidental contact with overhead power lines, which can result in electric shock or electrocution. Additionally, local regulations may vary based on specific site conditions, the type of electrical lines present, and other safety considerations. Therefore, being aware of and compliant with these regulations is crucial for creating a safe working environment.

The other options suggest greater distances, but the recommended 10 feet or local regulations provide a balance between safety and operational feasibility, reflecting common industry standards. Too much distance can lead to inefficient use of materials and space on a job site, while too little may compromise safety. It's also important to note that specific industries or job sites may have additional requirements that necessitate greater distances, which is why local regulations should always be consulted.
