ANSI/PHTA/ICC-7 2020 American National Standard for Suction Entrapment Avoidance in Swimming Pools, Wading Pools, Spas, Hot Tubs, and Catch Basins is a revision of ANSI/APSP/ICC-7 2013. This is the only standard that protects against the three root causes of entrapments: suction, water velocity and mechanical binding. Based on the best science and practices, PHTA-7 offers technically sound solutions to prevent all forms of entrapment: hair, limb, body, mechanical and evisceration. The ANSI/PHTA/ICC-7 2020 standard addresses how to calculate maximum flow for both commercial and residential pools. This key safety standard provides a model code for national, state and local officials, which PHTA urges all states to adopt. PHTA-7 is consistent with the Virginia Graeme Baker Pool and Spa Safety Act (VGBA) and current U.S. Consumer Product Safety Commission (CPSC) interpretations. A print version is also available in the PHTA Store.
