Employers must, by law, ensure an adequate supply of fresh air in the workplace and this has not changed.
Good ventilation can help reduce the risk of spreading coronavirus in the workplace.
It is important to focus on improving general ventilation, preferably through fresh air or mechanical systems.
Where possible, consider ways to maintain and increase the supply of fresh air, for example by opening windows and doors (unless fire doors).
