HSE updates guidance on supplying adequate ventilation in the workplace

The Health and Safety Executive (HSE) has updated its guidance on supplying adequate ventilation in the workplace. 

The update has taken place in response to the relaxation of coronavirus restrictions; the law already says that employers must make sure there’s an adequate supply of fresh air (ventilation) in enclosed areas of the workplace.

You can do this by using:

  • natural ventilation - fresh air comes in through open windows, doors or air vents. This is also known as ‘passive airflow’, or
  • mechanical ventilation - fans and ducts bring in fresh air from outside

Ventilation isn’t the only way of making sure you’re working safely. You should also make sure workers are keeping the workplace clean and washing their hands frequently. You can also identify other control measures by your risk assessment.

This guidance will help you and your workers:

  • identify poorly ventilated areas
  • decide on the steps you can take to improve ventilation
  • assess the risk from breathing in small particles of the virus (aerosol transmission) in enclosed areas.

The HSE reminds employers that adequate ventilation reduces how much virus is in the air.; it helps reduce the risk from aerosol transmission.

Here is a video on howo n using ventilation to tackle COVID-19. It provides basic advice on how you can use ventilation to help reduce the risk of Covid-19 transmission in your workplace.
