The British Occupational Hygiene Society (BOHS) in collaboration with HSE Occupational Hygienists develop a freely available tool for assessing general ventilation and COVID-19 transmission.
Good ventilation can help limit the risk of COVID-19 transmission, especially in enclosed spaces. The ventilation tool supports employers, building users and building owners by using a simple scoring system to indicate the effect their ventilation arrangements are likely to have on reducing COVID-19 transmission. It also provides recommendations for acting, where appropriate.
