The law says employers must make sure there’s an adequate supply of fresh air (ventilation) in enclosed areas of the workplace. This has not changed during the pandemic.
This guidance will help you and your workers:
- assess your workplace to identify poorly ventilated areas
- decide on the actions you can take to improve ventilation
Why ventilation is important
Someone who has coronavirus breathes out small particles (aerosols) of the virus.
Adequate ventilation reduces how much virus is in the air, so it reduces the risk of breathing in the virus.
Our guide on how ventilation helps you reduce the spread of COVID-19 summarises the main actions you should take.
Video on using ventilation to tackle COVID-19
The following video gives basic advice on how you can use ventilation to help reduce the risk of COVID-19 transmission in your workplace.
What to do in addition to ventilation
Although ventilation is important it doesn’t reduce:
- droplet transmission (from people being in close contact)
- contact transmission (touching surfaces)
You should still make sure you are working safely by:
- keeping your workplace clean
- ensuring that workers and others are washing their hands frequently
You can identify other control measures through your risk assessment.
We review and update this page regularly to reflect any changes in guidance.
