Key prevention

  • Conduct regular visual inspections of all power cords and tools to identify and remove damaged equipment before use.
  • Ensure all temporary power outlets are equipped with ground-fault circuit interrupters to prevent severe shocks in damp conditions.
  • Establish a strict policy that only qualified personnel are permitted to perform electrical repairs or modifications on-site.
  • Maintain clear distances from overhead power lines when operating heavy machinery or using ladders and scaffolding.
  • Provide comprehensive training to all workers on identifying potential electrical hazards and the correct procedures for reporting faulty equipment.
