Why the ‘Fresh Air’ in ‘Hands, Face, Space and Fresh Air’ is so important.


From ‘Hands, Face, Space’ to ‘Hands, Face, Space and Fresh Air’ – why is this difference so important?



The government have come with a new Coronavirus slogan ‘Hands, Face, Space and Fresh Air’ to replace their old one ‘Hands, Face, Space’. Why has ‘Fresh Air’ been added and is it really that important? As we all know, Covid-19 is an airborne virus, meaning it flies around in the air and is very likely to be transmitted in that way. So, making sure the air in confined spaces like offices and schools is clean is crucial for lowering transmission rates.


Proper ventilation is important for workplace hygiene in addition to individual things you can do like wear a mask and sanitise your hands. Every workplace should have good ventilation where the air in the room is being mixed with fresh air from outside since the risk transmission in enclosed spaces is so high.


Everyone can wash their hands and wear their masks but if you’re all breathing in a room with poor ventilation and there is an infected person in the room, the likelihood of other people catching the virus is shockingly high.


The way Covid-19 can be transmitted through the air is through aerosols. Aerosols are microdroplets released from sneezes and coughs that are 1 micrometre (0.001mm) in diameter - so small that they hover in the air for much longer than larger droplets that just drop to the ground.


Typically, thousands of aerosols can be expelled when someone sneezes or coughs, and they can stay in the air for hours, they can even travel tens of metres from where they originally were expelled from.


Now we know why ventilation is so important and how airborne viruses are spread, the question is, how can you make sure your premises are safe in terms of air quality?


The HSE recommends that there should be a flow of fresh air either by vents or windows that are opened. An addition to this is using air purifiers in your workplace. Air purifiers usually have filters like the true HEPA filter that filters out 99.9% of particles that are 0.3 microns in size or larger.


Another type of air purifier are ones that use UV light, UV-C light specifically – it kills 99.9% of bacteria and viruses by penetrating the cell and permanently damages the cell, killing it in the process.


All in all, we can understand now that the ‘Fresh Air’ in ‘Hands, Face, Space and Fresh Air’ is arguably the most important and measures should be taken to provide good ventilation as people return to work and school.
