At VSS our air quality testing is undertaken in accordance with the Health & Safety & Welfare at Work 1999 Act, with reference to Regulations 5 & 6 which stipulate cleanliness and regular inspection and maintenance of the ventilation systems.
Our guidance is based on threshold levels taken from CIBSE, World Health Organisation and REVHA guidelines.
Covid-19 has increased awareness that adequate ventilation is required to reduce how much virus is in the air. It also helps reduce the risk from aerosol transmission.
Aerosol transmission can happen when someone breathes in small particles in the air (aerosols) after a person with the virus has been in the same enclosed area.
The risk from aerosols is greater in areas that are poorly ventilated.
