Current through Register Vol. 48, No. 12, March 22, 2024
Swimming facilities and appurtenances, including other pools
associated with or provided as appurtenances to swimming pools, shall comply
with this Subpart.
a) Enclosures
1) The swimming pool area shall be completely
enclosed by a protective wall, fence or other barrier, at least 4 feet high,
measured on the inside and outside, and not providing ready footing for
climbing. The height of an opening under the bottom of the barrier shall not
exceed 4 inches. The openings in any barrier shall not exceed 4 inches in width
and height.
2) Each entrance into
the pool enclosure shall be equipped with a door or gate that is self-closing
and self-latching. This requirement is not necessary when people enter the pool
area through the bather preparation facility and lifeguards are provided in the
pool area. Doors and gates at all entrances to the pool enclosure shall be
equipped with hardware that permits secure locking of the entrance.
3) A balcony shall not overhang or extend
within 10 feet horizontally of any portion of the water surface of a swimming
pool.
4) Sand areas shall not be
allowed inside of the pool enclosure unless a barrier is provided to control
access to the pool. If access is allowed to sand areas, bathers passing from
the sand area to the pool area shall be required to pass through a shower
facility with heated or tempered water for removal of sand.
b) Bather Load. The Department
will compute a bather load for each swimming pool area. A bather load shall be
specified with the issuance of a construction permit for a new swimming pool.
In the case of multiple swimming pools contained within a common enclosure, the
Department may compute a combined bather load for the pool enclosure. The
criteria to be used for computing the bather load are as follows:
1) Shallow Area. Fifteen square feet of water
surface shall be required for each bather.
2) Deep Area. Twenty-five square feet of
water surface shall be required for each bather, with 300 square feet deducted
for each diving board or platform.
3) The bather load for wading pools shall be
computed at 15 square feet of pool water surface for each bather.
4) A designated plunge area or landing area
for a slide, as specified in Section
820.250, shall not be
considered in computing a bather load.
5) One bather shall be allowed for each 50
square feet of pool deck area in excess of the minimum specified in subsection
(j)(1).

licensed architect or structural engineer shall certify that the pool is
designed to withstand all anticipated hydraulic structural loadings for both
full and empty conditions. All appurtenances to the pool, such as diving boards
and slides, shall be designed to carry the anticipated load.
d) Material. Pools shall be constructed of
materials that provide a rigid, watertight shell with a smooth, impervious,
light-colored finish that is non-toxic and easily cleaned. The floor of shallow
areas shall have a slip-resistant finish. Pool vinyl liners may be installed
only over a base of concrete, steel or other rigid material.
e) Obstruction. An obstruction creating a
safety hazard shall not extend into or above the pool, or shall not protrude
from the floor of the pool. Certified safety covers for suction outlets shall
not protrude more than 2 inches from the floor or walls of the pool.
f) Slope of Pool Floor. The floor of a pool
shall slope downward toward the main drain. The slope in shallow areas shall
not exceed 1 foot vertical in 12 feet horizontal except for a slope directed
downward from a transition point, which shall not exceed 1 foot vertical in 3
feet horizontal. In portions of the pool with a depth greater than 5 feet, the
front slope of the deep area shall not be steeper than 1 foot in 3 feet. The
slope requirements are illustrated in Appendix A.Illustration A.
g) Transition Point. Transition points shall
be marked with a stripe on the pool floor at least 4 inches wide in a color
