BOHS and HSE introduce free online ventilation check tool

The tool is aimed to help limit the transmission of COVID-19 in workplaces

The British Occupational Hygiene Society (BOHS), a scientific charity, and the Chartered Society for Worker Health Protection has developed a free, online ventilation tool to help limit the transmission of COVID-19 in workplaces, in collaboration with the Health and Safety Executive.

With winter coming and businesses contemplating the challenges of COVID-19 and colder weather, the charity says, good ventilation is key to limit the risk of coronavirus amongst workers and provide clean air especially in enclosed spaces. The organisations developed this non-technical ventilation check tool to provide guidance and an indication of the effectiveness of the ventilation system used on reducing coronavirus transmission. The tool can be used by employers, building users, and building owners and does not aim to replace ventilation specialists or occupational hygienists assessing risks in a workplace, especially when it comes to more complex ventilation needs.

CO2 monitoring is also very important, as an increase in CO2 concentration in any area could be indicative of poor ventilation that needs improving. BOHS CO2 Monitoring guidance aims to provide basic information on why monitoring CO2 levels can help control the spread of coronavirus, when it does work well, what is a safe CO2 level and how to do the monitoring.

Andrew Curran, HSE’s Chief Scientific Officer, commented: “I’m really pleased to see the development of this practical tool which will help to inform decisions about ventilation in work spaces.”

BOHS CEO, Professor Kevin Bampton said: “Covid-19 has highlighted the central importance of air quality in protecting workers from illness. We hope that these tools will enable people better understand their working environment and the role ventilation plays in saving lives and preventing ill-health.”

Guidance on ventilation and CO2 monitoring can be found on BOHS COVID-19 hub.
