304.3 Aquatic vessels in flood hazard areas subject to high velocity wave action.Aquatic vessels <br /> installed in flood hazard areas subject to high velocity wave action (coastal high hazard areas)shall be <br /> designed and constructed in accordance with ASCE 24. <br /> 304.4 Protection of equipment. Equipment shall be elevated to or above the design flood elevation or <br /> be anchored to prevent flotation and protected to prevent water from entering or accumulating within the <br /> components during conditions of flooding. <br /> 304.5 GFCI protection. Electrical equipment installed below the design flood elevation shall be supplied <br /> by branch circuits that have ground-fault circuit interrupter protection for personnel. <br /> SECTION 305 <br /> BARRIER REQUIREMENTS <br /> 305.1 General. The provisions of this section shall apply to the design of barriers for all aquatic vessels. <br /> These design controls are intended to provide protection against the potential drowning and near <br /> drowning by restricting access to such vessels. These requirements provide an integrated level of <br /> protection against potential drowning through the use of physical barriers and warning devices. <br /> Exception: Portable residential spas and portable residential exercise spas. <br /> 305.2 Outdoor Swimming Pools. All outdoor aquatic vessels shall be surrounded by a barrier that <br /> complies with Sections 305.2.1 through 305.8. <br /> Exception: Spas or hot tubs with a lockable safety cover that complies with ASTM F1346. <br /> 305.2.1 Barrier height and clearances. The top of the barrier shall be at least 48 inches (1524 <br /> mm) above grade measured on the side of the barrier that faces away from the aquatic vessel <br /> around the entire perimeter of the vessel and for a distance of three (3) feet measured <br /> horizontally from the required barrier. The maximum vertical clearance between grade and the <br /> bottom of the barrier shall be 2 inches (51 mm)from surfaces that are not solid, such as grass or <br /> gravel, and measured on the side of the barrier that faces away from the vessel.Where the top of <br /> the vessel structure is above grade, the barrier shall be at ground level or mounted on top of the <br /> vessel structure, and the maximum vertical clearance between the top of the vessel structure and <br /> the bottom of the barrier shall be 4 inches (102 mm). The maximum vertical clearance between a <br /> surface below the barrier to a solid surface, such as concrete, and the bottom of the required <br /> barrier shall be four(4)inches(102 mm) measured on the side of the required barrier which faces <br /> away from the vessel. <br /> 305.2.2 Openings. Openings in the barrier shall not allow passage of a 4-inch-diameter (102 <br /> mm)sphere. <br /> 305.2.3 Solid barrier surfaces. Solid barriers that do not have openings shall not contain <br /> indentations or protrusions that form handholds and footholds, except for normal construction <br /> tolerances and tooled masonry joints. <br /> 305.2.4 Mesh restraining barrier/fence. Mesh fences, other than chain link fences in <br /> accordance with Section 305.2.7, shall be installed in accordance with the manufacturer's <br /> instructions and shall comply with the following: <br /> 1. The bottom of the mesh restraining fence shall be not more than 1 inch (25 mm) above the <br /> deck or installed surface or grade. <br /> ISPSC Public Version 1.0 <br /> Page 25 <br />
