Health and Safety
1.
All piers, floats, and platforms shall be in good repair,
and where applicable, the water depth shall be indicated by
printed numerals on the deck or planking.
2.
There shall be a minimum water depth of 10 feet for a
one-meter diving board and 13 feet for a three-meter board
or diving tower.
3.
For outdoor swimming areas in natural bodies of
water, the bottom shall be cleared of stumps, rocks, and
other obstacles.
4.
Diving boards shall be mounted on a firm foundation
and never on an insecure base, such as a float that can be
affected by shifting weight loads and wave action. The entire
length of the top surface of diving boards shall be covered
with nonskid material. The diving board shall be level. All
diving boards shall be installed in accordance with
manufacturer’s guidelines for the board by professional
swimming pool installers who shall certify in writing to the
facility that the diving board is adequately installed in
accordance with manufacturer’s guidelines for the board, in a
commercially reasonable manner, located so as to allow a
child to safely enter the water from the diving board, and that
the diving board is safe for its intended use. Facilities with
existing pools equipped with diving boards that are unable to
obtain the required certification within 60 days of the
adoption of this regulation shall have the diving boards
removed.

Swimming
pools, when in
use, shall be
continuously disinfected by a chemical that imparts an
easily measured free available residual effect. When
chlorine is used, a free chlorine residual of at least 0.4
ppm shall be maintained throughout the pool whenever
it is open or in use. If other halogens are used, residuals
of equivalent disinfecting strength shall be maintained.
6.
A testing kit for measuring the concentration of
the disinfectant, accurate within 0.1 ppm, shall be
provided at each swimming pool.
Swimming pool water shall be maintained in an alkaline
condition as indicated by a pH of not less than 7.2 and not
over 8.2. A pH testing kit accurate to the nearest 0.2 pH unit
shall be provided at each swimming pool. The alkalinity of
the water shall be at least 50 ppm, as measured by the
methyl-orange test. The following chart may be used for
reference:
7.
If cyanuric acid is used to stabilize the free available
residual chlorine, or if one of the chlorinated isocyanurate
compounds is used as the disinfecting chemical in a
swimming pool, the concentration of cyanuric acid in the
water shall be at least 30 mg/L but shall not exceed 100
mg/L. The free available residual chlorine, of at least the
following concentrations, depending upon the pH of the
water, shall be maintained:

8.
The water in a swimming pool shall have sufficient
clarity at all times so that a black disk, six inches in
diameter, is readily visible when placed on a white field at
the deepest point of the pool. The pool shall be closed
immediately if this requirement cannot be met.
9.
For natural bodies of water (e.g., lakes, rivers, streams,
etc.), sewage treatment plants or other discharge lines shall
not be within 750 feet of swimming areas.
