Airport Authority Hong Kong (AA) has implemented the latest disinfection technology at Hong Kong International Airport to reduce the risk of the Covid-19 infection spreading amongst passengers and airport staff.

The new measures include disinfection channels, antimicrobial coating and autonomous cleaning robots.

Hong Kong International Airport is testing a full-body disinfection channel facility dubbed CLeanTech in live operations. It is a fully enclosed facility that offers complete disinfection and sanitising procedures to users within 40 seconds.

The antimicrobial coating in the interior surface of the channel kills bacteria and viruses on human bodies and clothing using photocatalyst and ‘nano needles’ technology.

It also uses sanitising spray for instant disinfection. To prevent cross-contamination between the outside and inside environment, the channel is kept under negative pressure.

The facility is currently designated for use by staff involved in public health and quarantine duties at the airport in relation to arriving passengers.

Furthermore, AA is conducting a pilot test of applying antimicrobial coating at all passenger facilities in a bid to prevent contamination.

Hong Kong International Airport said it will consider implementing it as a long-term disinfection measure after the completion of the trial in May.

It has also deployed autonomous cleaning robots, equipped with ultraviolet light steriliser and air steriliser, for the thorough disinfection of public areas and passenger facilities.

These robots operate round-the-clock in public toilets and key operating areas in the terminal building. It can sterilise up to 99.99% of bacteria, including both the air and object surfaces, in just ten minutes.

Airport Authority Hong Kong Service Delivery Deputy Director Steven Yiu said: “The safety and wellbeing of airport staff and passengers are always our first priority.

“Although air traffic has been impacted by the pandemic, the AA spares no effort in ensuring that the airport is a safe environment for all users. We will continue to look into new measures to enhance our cleaning and disinfection work.”
