What does maintaining proper clearance from overhead power lines ensure?

Maintaining proper clearance from overhead power lines is crucial primarily for worker safety. Power lines can carry high voltage, and if machinery or hoisting equipment comes into contact with them, it can lead to severe injuries or fatal accidents for operators and nearby workers. This safety measure is essential to prevent electrical shock, which can occur if a worker or equipment inadvertently gets too close to these power lines. By adhering to guidelines regarding clearance, workers can mitigate the risk of electrocution and ensure a safer working environment.

The other options like effective load lifting and reduced equipment wear do not specifically address the serious risks associated with power lines. While enhanced driving speed may be beneficial in some scenarios, it is not relevant when considering the safety protocols necessary around overhead power lines. Therefore, the focus remains on the critical aspect of protecting workers through maintaining adequate distances from these hazards.
