COVID-19 – Air conditioning at work

COVID-19 – Air conditioning at work

Public Health Gibraltar are advising against the use of air-conditioning in workplaces where possible. Good natural ventilation, with windows open, and sufficient physical distancing are preferred options.

The transmission of COVID-19 is thought to occur through respiratory droplets generated by coughing and/or sneezing, or through contact with contaminated surfaces.

Droplets will generally fall out of the air-stream within a short distance (depending on airflow speed and direction), hence the guidance to remain at least 2 metres apart. However, droplets may evaporate, reducing in size and mass and travel further in air-streams – increasing the risk of airborne transmission. 

While airborne transmission is not thought to be a primary route of transmission, there is a growing body of evidence that COVID-19 can also be spread through the air, particularly in poorly ventilated indoor spaces. Ventilation provision in workplaces and buildings should be reviewed in light of this. Read more here.
