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 entrapment and evisceration. The ANSI/PHTA/ICC-7 2020 addresses how to calculate maximum flow for both commercial and residential pools. This key PHTA safety standard provides a model code for national, state and local officials, which PHTA urges all states to adopt. ANSI/PHTA/ICC-7 is consistent with the Virginia Graeme Baker Pool and Spa Safety Act and current U.S. Consumer Product Safety Commission (CPSC) interpretations.
