Restaurants asked to abide by state's new Safer Dining Program and last updated 2021-02-10 06:06:10-05 Now that indoor dining has reopened in Michigan, restaurants are being asked to voluntarily comply with the stateâs new âMI COVID-19 Safer Diningâ program. Restaurants that want to become a certified safe dining space will have to work with a licensed HVAC contractor who can recommend changes to air ventilation to improve circulation and reduce the risk of COVID-19 spread. The American Society for Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) has been guiding multiple states in writing new codes regarding indoor air issues, recommending a certification checklist businesses can follow to mitigate the spread of Covid-19. The CDC, EPA, and MI-OSHA are also helping businesses navigate this process, helping them develop "best practices" moving forward.
