Presenters: Dewey Case, Technical Director, Council for the Model Aquatic Health Code; Michele Hlavsa, RN, MPH, Epidemiologist, U.S. Centers for Disease Control and Prevention; Joseph Laco, Commander, U.S. Public Health Service, Centers for Disease Control and Prevention; and Vincent Hill, Chief, Waterborne Disease Prevention Branch, Centers for Disease Control and Prevention

 

Summary

The CDC has revised the Model Aquatic Health Code (MAHC) three times, based on national input. For this update cycle, the Council for the MAHC (CMAHC) collected and assessed change requests (CRs) and relayed recommended MAHC revisions to CDC. During this session, we’ll examine the 2021 MAHC (4th edition) and its representation of over 300 approved CRs. Topics include cyanuric acid, removal of Cryptosporidium oocysts by filtration, safety ropes and float lines, suction outlet fitting assemblies, and differentiating among the types of chlorine and between enclosures and barriers.

 

Learning Objectives

  • Identify key revisions in the 2021 MAHC
  • Describe next steps to protect patron and aquatic staff health and safety
