5.1 This guide sets forth minimum standard requirements for use in local codes and ordinances relating to non-residential outdoor swimming pools, hot tubs, spas, and waters. This guide does not have the effect of law, nor is it intended to supersede local codes and ordinances of a more restrictive nature.

1.1 This guide provides recommended minimum requirements for various types of fences for non-residential outdoor swimming pools, hot tubs and spas.

1.2 The various types of fences may be chain link, wood, vinyl, ornamental steel or aluminum, welded wire, expanded metal, composite or others that would be incorporated into a design necessary to support the structure considering its height, application, location, and climatic condition. All types of fences shall be in accordance with ASTM standards.

1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The SI values stated in parentheses are provided for information purposes only.
