How must metal structures or parts located near pools be treated according to NEC Article 680?

According to NEC Article 680, metal structures or parts located near pools must be bonded to the grounding system to mitigate shock danger. This bonding is a critical safety measure intended to prevent electric shock hazards. When metal components, such as handrails, ladders, or other related equipment, are not properly bonded, they could carry stray electrical currents, especially in a wet environment like a pool.

By bonding these metal parts to the grounding system, any unintended electrical current can safely flow to the ground instead of posing a risk to individuals who come into contact with those metal structures. This practice helps ensure that the electrical potential of the metal is equalized with the surrounding ground, significantly reducing the risk of electrical shock. The requirement for bonding is especially vital in environments where water is present, as water increases the conductivity and potential for electric shock.

Options that suggest insulation to prevent corrosion, leaving parts unbonded if painted, or prohibiting their proximity to pools do not address the vital safety needs outlined in the NEC for preventing electric shock in areas where water and electricity may coexist. Bonding provides a necessary layer of safety that these other approaches do not offer.
