A Checklist identifying key steps owners and operators of commercial establishments (such as retail stores, services facilities, or activity venues) should take to mitigate the risk of liability to customers that claim to have contracted or been exposed to a contagious or infectious disease while in the business's premises during a public health emergency, including an epidemic or pandemic. This Checklist addresses compliance with governmental and public health authorities' requirements and guidelines, implementation of measures to reduce exposure risk, use of warnings and liability waivers, and insurance coverage.
