Which of the following practices best ensures safety when working near energized equipment?

Utilizing insulated tools and personal protective equipment is the most effective practice for ensuring safety when working near energized equipment. Insulated tools are designed to prevent electrical current from passing through them, which significantly reduces the risk of electric shock. Personal protective equipment, such as rubber gloves and arc-rated clothing, provides an additional layer of safety, protecting the worker from potential electrical hazards and burns.

Together, these measures create a barrier between the worker and the energized equipment, allowing for safer operation and maintenance. This is particularly important in environments where electrical hazards are present, as even a momentary lapse in safety can lead to serious injuries.
