Electricity is the second leading cause of death in construction, accounting for over 600 deaths annually. Proper safety procedures and equipment are required to prevent electrical accidents and injuries. Key risks include contacting energized power lines or equipment, using defective tools or cords, and failing to follow lockout/tagout procedures to de-energize circuits before working. Proper grounding, GFCI protection, insulation, and avoiding overloads are vital for electrical safety.
