Creating a Covid-19 Secure Dining Experience

The risk of COVID-19 transmission significantly increases in indoor settings. Dining areas in restaurants are the prime example of such an indoor setting. One such outbreak occurred in a restaurant in Guangzhou, China on 24th January 2020. Close prolonged contact between numerous people in an enclosed space significantly affected the rate of virus cross infected.


Transmission risks at dining areas depend on the factors such as ventilation strategies, layout, occupancy levels etc. However, risk mitigation in a restaurant on an ongoing basis can be challenging due to the close social proximity of diners. Moreover, the strategies should also be considerate of the occupancy levels to maximise cash flow while also minimising the associated risks

Recommending seating arrangements

Evaluate aerosol spread pattern for the existing dining layout. The evaluation enables understanding the transmission risks associated with the existing dining layout. Recommend adjustments to the layout and compliance with government guidelines. 

Guidance on improving occupancy

Evaluate aerosol spread pattern for the existing ventilation strategies or HVAC settings. Understand transmission risks associated with the existing strategies. Explore and develop new ventilation strategies to minimise transmission risks on an ongoing basis.

Developing safer dining practices

Based on developed ventilation and occupancy strategies, develop healthy work practices on an ongoing basis. For example, placing screen guard at strategically important locations.

Developing targeted cleaning policies

Identifying spread patterns of heavy droplets and aerosols for targeted surface and zonal cleanings.
