FAQ n.115307

What precautions will be taken to avoid contamination via air conditioning systems?


Airport operators have been advised to ensure proper air ventilation of their facilities. This includes minimising the percentage of air recirculation and favouring when possible the use of fresh air, in accordance with international guidance for ventilation of indoor public spaces.

Furthermore, heating, ventilation and air conditioning (HVAC) systems should be optimised to ensure a high rate of air change. In older facilities, subject to airport/terminal construction and meteorological conditions, windows can be kept open for additional supply of fresh air, subject to the absence of horizontal air flows.
