Coronavirus updated guidance: Ventilation and air conditioning

HSE has published updated guidance on ventilation and air conditioning during the coronavirus pandemic. 

The law requires employers to ensure an adequate supply of fresh air in the workplace and this has not changed during the pandemic. Good ventilation, together with social distancing, keeping your workplace clean and frequent handwashing, can help reduce the risk of spreading coronavirus.

Our updated guidance will help you identify poorly ventilated areas of your workplace and provides steps you can take to improve ventilation while maintaining a comfortable temperature. It will apply in most workplaces and includes guidance on:

  • balancing ventilation with keeping people warm
  • identifying poorly ventilated areas
  • how to improve ventilation
  • ventilation in vehicles

The new ventilation and air conditioning guidance is part of our advice on making your workplace COVID-secure.
