What safety practices should be employed while working near power lines?

Maintaining a safe distance from power lines and avoiding operating the boom near them is crucial for safety when working with equipment like telehandlers. This practice minimizes the risk of electrocution, which can occur if the boom or any part of the telehandler makes contact with or gets too close to power lines. Utility regulations and safety guidelines often specify the minimum safe distances that should be maintained from power lines, and adhering to these regulations helps protect both the operator and others on the site.

The other options do not promote effective safety. Ignoring utility regulations is fundamentally dangerous. Wearing insulated gloves and boots, while beneficial in certain electrical work contexts, does not substitute for maintaining safe distances from power lines and does not prevent accidents involving large machinery. Working at night when visibility is low introduces additional risks and hazards, as this can lead to accidents due to impaired sightlines and increased chance of errors. Thus, option B stands out as the most effective and prudent safety measure.
