The Ministry of Health has recently updated guidance around using ventilation to help reduce the risks of Covid-19.
SARS-CoV-2, the virus that causes COVID-19, spreads in particles that escape from an infected persons mouth or nose through the air.
The risk of infection can be reduced by:
- air ventilation (which exchanges old air for fresh air)
- air cleaning (which removes the virus in the air without changing the air).
In most situations, you should combine these methods with other personal protection methods such as vaccination, physical distancing and masks.
The guidance includes some interesting information about HVAC units and other systems that are relevant to hospitality venues. Making sure your current systems are working properly is important including regular cleaning and maintenance to ensure they are working to their full potential.
