All Mini-MAHCs reference content from the 2018 MAHC (3rd Edition).
Specific public health issues addressed in the MAHC are often spread across multiple chapters. These Mini-MAHCs, which were created using the 2018 version of the MAHC, are intended to make the MAHC more accessible by aggregating the code and annex language on a specific public health issue into more concise documents. This will help environmental health practitioners and operators of public treated aquatic venues quickly find relevant MAHC guidelines and rationale to address specific public health issues and improve patron and staff health and safety.
This Mini-MAHC Code and Annex focus on preventing pool chemical injuries. It includes language to help decrease injury risk through safe equipment room and chemical storage area design and construction, pool chemical safety training, pool chemical safety, and chemical spill procedures and emergency response.
This Mini-MAHC Code and Annex focus on preventing in-line production of toxic chlorine gas, which can occur if there is no or low water flow in the recirculation system but the chemical feeders continue running. It includes language to help decrease the likelihood of the events through automatic deactivation of chemical feeders in the event of no or low water flow.
This Mini-MAHC Code and Annex focus on reducing the spread of Cryptosporidium (Crypto). It includes language to help decrease the public health impact of Crypto contamination by killing the parasite using secondary or supplemental (e.g., UV or ozone) disinfection and hyperchlorination after diarrheal fecal incidents (or high-risk Crypto contamination events).
This Mini-MAHC Code and Annex focus on bather hygiene and diaper changing. It includes language to help decrease the potential for water contamination through the routine use of properly operating bathrooms and diaper-changing stations and swimmer education to promote healthy behaviors.
