When working near unknown overhead power lines, what is the minimum safe distance to maintain?

The correct answer is significant because maintaining a safe distance from unknown overhead power lines is crucial for ensuring the safety of workers. In many protocols and safety standards, including those provided by various safety organizations and regulatory agencies, a minimum safe distance of 7.0 meters is often recommended when working near electrical overhead lines. This distance is established to reduce the risk of accidental contact or arcing, which can result in severe electrical hazards.

By adhering to this 7.0-meter rule, workers minimize exposure to the dangers associated with high-voltage lines, including electric shock or electrocution. Such regulations ensure there is an adequate buffer zone to protect personnel and equipment from potential electrical hazards that can arise from unforeseen line sagging or swinging.

Other options, while they may represent safe distances in specific contexts, do not meet the requirements set for overhead power lines in general situations. They may be appropriate for different circumstances or types of electrical work but do not align with the universal safety standards that highlight the importance of the 7.0-meter guideline. Understanding these distances reinforces the need for thorough site assessments and safety precautions when working near overhead power lines.
