What lighting requirement exists for working areas after dark in surface mining?

Proper illumination is essential in surface mining working areas after dark to ensure the safety of all personnel. Adequate lighting minimizes the risks of accidents and injuries by allowing workers to clearly see their surroundings, equipment, and any potential hazards. This requirement aligns with safety regulations designed to protect workers in potentially dangerous environments.

While dim lighting might reduce visibility, it is insufficient for the tasks and operations that occur in mining areas, which can involve heavy machinery and complex activities. The absence of a specific requirement does not provide a safe environment for workers, and relying on natural light is not feasible during nighttime operations. Thus, proper illumination is not just a recommendation but a critical necessity to maintain safety standards in surface mining environments after dark.
