Airport Authority Hong Kong (AA) has announced that it is adopting latest cleaning technologies at Hong Kong International Airport (HKIA) in its efforts to protect passengers and airport staff from COVID-19. The technologies include disinfection channels, antimicrobial coating and autonomous cleaning robots.
Steven Yiu, Deputy Director, Service Delivery of the AA, 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.”
Full-body disinfection channel facility
HKIA has become the first airport to trial a new full-body disinfection channel facility, called “CleanTech”, in live operation. Staff using the facility will have their temperature checked before entering an enclosed channel for the 40-second disinfection and sanitising procedures.
The interior surface of the channel is equipped with antimicrobial coating which can remotely kill virus and bacteria on human bodies and clothing by using the technologies of photocatalyst and nano needles. Sanitising spray is also applied for instant disinfection. The channel is kept under negative pressure to prevent cross-contamination between the outside and inside environment. Currently, the facility is designated for use by staff who take part in public health and quarantine duties at the airport in relation to arriving passengers.
Autonomous cleaning robots
Autonomous cleaning robots are also deployed to ensure thorough disinfection of public areas and passenger facilities in HKIA. Intelligent Sterilization Robot, equipped with ultra violet light steriliser and air steriliser, is deployed round-the-clock in public toilets and key operating areas in the terminal building. The robot can move around autonomously and sterilise up to 99.99% of bacteria in its vicinity, including both the air and object surfaces, in just 10 minutes.
Antimicrobial coating
Moreover, the airport is also conducting a pilot test of applying antimicrobial coating at all passenger facilities. An invisible coating to destroy germs, bacteria and viruses is applied to high-touch surfaces in the terminal, including handles and seats of Automated People Movers and passenger buses, smart check-in kiosks and check-in counters, toilets, seating area in the terminal, baggage trolleys, elevator buttons, and more. After completion of the trial in May, AA will consider implementing it as a long-term disinfection measure.
