Electrical safety in urban outdoor children's play areas requires strict adherence to grounding resistance standards to prevent electric shock hazards. International standards including IEC 60364-7-702 and ASTM F1487 specify that all metallic parts of playground furniture that could become energized must have a grounding resistance not exceeding 1 ohm. Regular testing using fall-of-potential or clamp-on methods ensures continuous compliance. Proper earthing systems must be installed to divert fault currents safely to the ground, with annual inspections recommended for public play facilities. These measures are critical for preventing electrical accidents in playgrounds where moisture, equipment wear, and environmental factors can create potential electrocution risks. Municipalities and playground operators must maintain documentation of all grounding tests to demonstrate compliance with local safety regulations.
