Which statement about the approach boundaries is true?

The correct statement regarding approach boundaries is that they are determined by system voltage and equipment type. Approach boundaries are crucial for ensuring safety during work on or near electrical equipment and are defined to minimize the risk of electrical shock or arc flash incidents.

The reason this statement is accurate lies in the fact that the approach boundaries, namely limited approach, restricted approach, and prohibited approach boundaries, are established based on various factors such as the voltage of the system and the characteristics of the equipment in use. For example, higher voltages create larger approach boundaries to ensure that workers maintain safe distances from sources of electrical hazards.

Understanding this aspect allows for the implementation of appropriate safety measures tailored to specific situations rather than applying a one-size-fits-all approach. Therefore, adherence to these boundaries is essential for protecting workers from potential electrical hazards during maintenance or operational tasks.
