Which of the following is NOT a method to ensure safety when working near energized lines?

The answer is correct because ignoring warning signs is fundamentally against safety protocols and practices. In the context of working near energized lines, warning signs serve as critical alerts to potential hazards. They are designed to inform personnel about the risks of electrical shock or other dangers present in the area. Ignoring these warnings can lead to severe accidents or fatalities, as it undermines all other safety measures in place.

The other methods listed are all important safety practices. Maintaining Minimum Approach Distance is a key safety protocol that ensures workers stay a safe distance away from live electrical equipment to reduce the risk of electrical shock. The use of protective gear, such as insulated gloves and non-conductive footwear, helps to protect workers from potential electrical hazards. Testing lines with a high voltage voltmeter is a crucial step in confirming that lines are de-energized before work begins, thereby ensuring that workers do not inadvertently come into contact with energized lines. Each of these methods contributes to establishing a safe work environment near energized lines.
