R 325.2122 Construction shapes, materials, surfaces, and loads.

Rule 22. (1) A swimming pool owner shall ensure that the pool and appurtenances are shaped and arranged so that the maintenance of safe and sanitary conditions and the recirculation of the water are not impaired. Nothing shall extend into or above a swimming pool tank so as to create a safety hazard. (2) A swimming pool owner shall ensure that a pool and appurtenances are constructed of materials that are inert, nontoxic to humans, impervious, durable, and strong enough to withstand structural stresses. (3) A pool owner shall ensure that a finished surface of a swimming pool wall or floor does not have sharp edges, open cracks, or open joints and is slip-resistant, easily cleanable, nonabsorbent, and light-colored, except that a dark marking may be inserted against a light background. (4) A swimming pool owner shall ensure that a pool tank is designed and constructed to withstand all anticipated loadings for both full and empty conditions. If a swimming pool tank is subject to external hydrostatic pressure, then the pool owner shall provide means to relieve the pressure.
