What is the Minimum Approach Distance (MAD) in electrical work?

The Minimum Approach Distance (MAD) refers specifically to the closest safe distance that a qualified electrical worker can approach an exposed electrical source or area that presents a potential shock or arc flash hazard. This distance is determined based on various factors such as the voltage level, the type of work being performed, and the safety protocols in place, ensuring that workers can perform tasks safely without risking exposure to live electrical components.

Understanding MAD is crucial for maintaining safety standards in electrical work, as it helps to prevent accidental contact with energized parts, thereby reducing the risk of electrical injuries. Qualified workers receive training that informs them about appropriate MAD guidelines according to industry regulations and best practices, which is essential for their protection while working near potentially hazardous environments.
