Many building users are unsure of the guidance when it comes to using air conditioning and ventilation systems during the Coronavirus pandemic.

Our conversations with businesses have revealed many feel concerned about the risks of using the systems, with some wondering if they should be using them at all at present. Here, we share the latest advice from the Health and Safety Executive:

General ventilation

The fact is that employers must by law ensure an adequate supply of fresh air in the workplace. This rule has not changed in light of the pandemic and good ventilation can actually help reduce the risk of spreading the virus.

Building users should therefore focus on improving general ventilation by increasing the supply of fresh air and improving outside air circulation. This can be as easy as opening windows and doors and using ceiling and desk fans.

Air conditioning

According to HSE, the risk of air conditioning spreading Covid-19 in the workplace is ‘extremely low as long as there is an adequate supply of fresh air and ventilation’.

Most types of air conditioning systems can continue to be used as normal but, centralised ventilation systems that remove and circulate air to different rooms are not recommended. Instead, turn off recirculation and use a fresh air supply.

Air conditioning systems that mix extracted air with fresh do not need to be adjusted. Neither do portable units or systems in individual rooms, as these operate on 100 percent recirculation.

Keep it fresh

Whatever air conditioning system in use, it is important to maintain a good supply of fresh air ventilation in the room.

And, if you’re unsure of the guidance for your specific system, get in touch. Our experienced team of engineers will be happy to assist with your ventilation requirements.
