What is the minimal approach distance a Class A employee must maintain when working near Signal Line and Catenary?

The minimal approach distance a Class A employee must maintain when working near Signal Line and Catenary is crucial for ensuring safety while operating near high voltage equipment. Maintaining a distance of at least 3 feet is essential to minimize the risk of electric shock or arc flash incidents, which can occur due to proximity to energized lines. This distance allows for a safe margin when working in areas where there may be exposed electrical components, helping to protect employees from potential hazards associated with electrical systems used in trains and signal operations. Adhering to this established safety standard helps foster a culture of safety and vigilance in environments where electrical equipment is present.
