(4) "Plummet" means a vertical line which passes through the end of, and which is at the
center line of, a diving board or diving platform.
(5) A swimming pool owner shall install diving equipment in compliance with this rule
and the equipment manufacturer's recommendations.
(6) A swimming pool owner shall ensure that a diving board, platform, and appurtenances
meet all of the following requirements:
(a) Be constructed to ensure stability and safely carry the maximum anticipated loads.
(b) Be constructed of corrosion-resistant, easily cleanable, nonabsorbent, and slip-
resistant materials.
(c) Have handholds on both sides of the ladder or stairway to a diving board or diving
platform.
(d) For a diving stand or platform 1.0 meter or higher above the water, have guard railings
on both sides of the diving board which extend to a position above the edge of the water
and which are equipped with intermediate rails. A diving stand or platform used
exclusively for competitive purposes is exempt from this subdivision.
(7) A swimming pool owner shall consider the safety of swimmers and divers in the
location and orientation of diving facilities. A swimming pool owner shall locate all diving
boards and diving platforms at a pool on the same wall.
(8) For pools that have diving facilities which were constructed before the effective date
of this rule and which do not comply with this rule, the department may approve the diving
facilities for competitive purposes. For competitive purposes, a swimming pool owner shall
ensure that the pool diving depths and facilities meet the requirements in effect on March
24, 1971 and shall operate the facilities in accordance with R 325.2198.
(9) If a pool is not in compliance with the requirements of this rule, and if the department
has issued a correction order to remedy an unsafe condition under R 325.2114, then a
swimming pool owner shall remove a diving facility or bring it into compliance with this
rule.
