    PUBLIC SWIMMING POOLS

    SECTION401
    GENERAL

    401.1 Public swimming pools.

    The provisions of this chapter shall apply to public swimming pools. Public swimming pools covered in this chapter include Class A, Class B, Class C and Class E pools.

    401.2 Scope.

    The requirements contained in this chapter provide specifications for the design, equipment, operation, warning signs, installation, sanitation, new construction, and alteration of public swimming pools.

    401.3 General.

    In addition to the requirements of this chapter, public swimming pools shall comply with the requirements of Chapter 3.

    401.4 Dimensional tolerances.

    Finished pool dimensions, for other than Class A pools, shall be held within the construction tolerances shown in Table 401.4. Other dimensions, unless otherwise specified, shall have a tolerance of ± 2 inches (51 mm).

    TABLE 401.4

    CONSTRUCTION TOLERANCES

    DESIGN ASPECTCONSTRUCTION TOLERANCE
    Depth–deep area, including diving area± 3 inches
    Depth–shallow area± 2 inches
    Length–overall± 3 inches
    Step treads & risers± 1/2 inch
    Wall slopes± 3 degrees
    Waterline–pools with adjustable weir skimmers± 1/4 inch
    Waterline–pools with nonadjustable skimming systems (gutters)± 1/8 inch
    Width–overall± 3 inches
    All dimensions not otherwise specified herein± 2 inches

    For SI: 1 inch = 25.4 mm, 1 degree = 0.017 radians.

    401.4.1 Class A pool tolerances.

    Dimensional tolerances for Class A pools shall be determined by the authority that governs such pools.

    401.5 Floor slope.

    Except where required to meet the accessibility requirements in accordance with Section 307.9, the slope of the floor in the shallow area of a pool shall not exceed 1 unit vertical in 10 units horizontal (10-percent slope) for Class C pools and 1 unit vertical in 12 units horizontal (8-percent slope) for Class B pools. The slope limit shall apply in any direction to the point of the first slope change, where a slope change exists. The point of the first slope change shall be defined as the point at which the floor slope exceeds 1 unit vertical in 10 units horizontal (10-percent slope) for Class C pools and 1 unit vertical in 12 units horizontal (8-percent slope) for Class B pools.

    401.6 Dimensions for Class A pools.

    Class A pools shall be designed and constructed to provide the dimensions determined by the authority that governs such pools.
