This winter, we could be in for yet another season in which the spread of viruses makes people hesitant to eat out. Now is a good time to ensure your indoor dining areas feel as safe as possible. While it’s more common for COVID-19 to spread through close contact with an infected person, airborne transmission can occur in spaces with poor ventilation. The CDC advises you have your ventilation systems checked to make sure they are operating efficiently, and also increase the circulation of outdoor air by opening windows and doors and prioritizing outdoor seating. Also consider running your HVAC system at maximum outdoor airflow for two hours before and after it is occupied, checking filters for proper installation and function, and possibly improving the engineering controls of the system to enhance ventilation efficiency.
