3.11.4.1.Diving Boards or Platforms
(1) No diving board or diving platform shall be installed in a public pool unless the requirements of Sentences (5) to
(17) are met but the requirements for a diving platform do not apply to a starting platform.
(2) No diving board or diving platform shall be installed in a modified pool or a wave action pool.
(3) Where a public pool is equipped with a diving board or a diving platform, the board or platform shall have a non-
slip surface.
(4) Where a diving board or a diving platform in a public pool is more than 600 mm above the water surface, the board
or platform shall be equipped with one or more adjacent handrails.
(5) Where a public pool is equipped with a diving board or a diving platform not more than 3 m in height above the
water surface, the pool shall be designed and constructed in conformance with Sentences (6) to (15).
(6) The depth of water in the area directly below a horizontal semi-circle in front of a diving board or diving platform
having a radius of 3 m measured from any point on the front end of the board or platform shall not be less than
(a) 2 750 mm, where a board is 600 mm or less in height above the water surface,
(b) 3 m, where a board or platform is greater than 600 mm but not more than 1 000 mm in height above the water
surface, and
(c) 3.65 m, where a board or platform is greater than 1 000 mm but not more than 3 m in height above the water surface.
(7) Except as permitted in Sentence (8), the water depth in a public pool shall be at least 1 350 mm at the horizontal arc
having a radius of 9 m measured from any point on the front end of the diving board or diving platform and intersecting
the vertical projections of the walls of the pool.
(8) Where a Class B pool is equipped with a diving board 600 mm or less in height above the water
(a) the water depth shall be at least 1 350 mm at the horizontal arc having a radius of 7.5 m measured from any point on
the front end of the diving board, and
(b) a warning notice, on which is printed in letters at least 150 mm high, the words DANGER — AVOID DEEP OR
LONG DIVES, shall be posted in a location clearly visible to divers.
(9) The slope of the bottom of a public pool having a diving board or diving platform shall not change by more than
17% where the water depth is less than the applicable depth set out in Sentence (6) and greater than the depth set out in
Sentence (7) or (8), as applicable.
(10) The horizontal distance between the vertical projection of the centre line of a diving board or diving platform and
the vertical projection of the centre line of another board or platform shall be at least 2 750 mm.
(11) The horizontal distance between the centre line of a diving board or diving platform and the vertical projection of
the closest side or any ledge on the closest side of a public pool shall be at least
(a) 3 m, where a diving board or diving platform is 1 000 mm or less in height above the water surface, and
(b) 3.6 m, where a diving board or diving platform is greater than 1 000 mm in height above the water surface.
(12) A diving board or a diving platform 600 mm or less in height above the water surface shall project over the water a
horizontal distance of at least 900 mm from the vertical projection of a pool wall under it.
(13) A diving board greater than 600 mm in height above the water surface shall project over the water a horizontal
distance of at least 1 500 mm from the vertical projection of the pool wall under it.
(14) A diving platform greater than 600 mm in height above the water surface shall project a horizontal distance of at
least 1 200 mm from the vertical projection of the pool wall under it.
(15) The space above a diving board or diving platform shall be unobstructed and shall consist of at least
(a) a space having a width of 2 500 mm on each side of the centre line of the board or platform, a length equal to the
sum of the horizontal distance the board or platform projects over the water plus 3 m, and a height of,
(i) 3.65 m above a diving board 3.65 m or less in length,
(ii) 5 m above a diving board greater than 3.65 m in length, or
(iii) 3 m above a diving platform, and
(b) the space below the planes originating from the front and sides of the uppermost horizontal plane of the space
determined under Clause (a) and sloping downwards at 30° from the horizontal.
(16) A diving board or diving platform greater in height than 3 m above the water surface shall be equipped with a gate,
barrier or other device capable of preventing access to the diving board or diving platform.
(17) Where a public pool is to be equipped with diving boards or diving platforms greater than 3 m in height above the
water surface, the design of the diving boards or diving platforms and the corresponding water depths and clearances shall
be in accordance with FINA, “Rules and Regulations - FINA Facilities Rules 2021-2025 – FR3 Diving Facilities.”
