AEDs in Missouri schools
Missouri reaches schools through a required cardiac emergency response plan (CERP). From 2026-27 CERP must implement AED placement incl. each athletic venue; purchase not required unless legislature appropriates funds (L. 2025 SB 68). The law is RSMo 160.482. A CERP that places AEDs means the school has to buy them.
AEDs in Missouri gyms and health clubs
Missouri has no statewide AED mandate for gyms or health clubs. Many clubs still keep one because members are high-risk and insurers ask about it.
Workplaces and government buildings in Missouri
We found no general Missouri law that requires private employers to have an AED, and no verified mandate for state buildings. Federal OSHA does not require AEDs either, though it encourages employers to consider them. Local fire codes and building codes can add requirements, so check with your local authority.
Good Samaritan protection in Missouri
Every state protects people who use an AED in good faith from civil liability (SCA Foundation review of state AED laws). Most of these laws expect the AED to be maintained and, in some states, registered with local EMS. A unit with expired pads or a dead battery can weaken the protection.
