Implementing lockout/tagout procedures is essential for minimizing arc flashes during electrical work because these procedures ensure that energy sources are properly shut off and cannot be inadvertently re-energized while maintenance or inspection activities are being performed. Lockout/tagout involves placing locks and tags on energy-isolating devices to control hazardous energy. This practice not only protects the worker from electric shock but also significantly reduces the risk of arc flash incidents, which can occur when electrical equipment is unintentionally energized during maintenance.

While proper grounding techniques and the use of non-conductive tools contribute to worker safety and risk reduction, they do not specifically address the prevention of arc flash events. Sunglasses, while helpful in protecting eyes from bright flashes, do not prevent arc flashes from occurring. Thus, the implementation of lockout/tagout procedures stands out as the most critical practice for ensuring safety and minimizing the risk of arc flashes.
