Hong Kong Airport Employs Latest Technology in Fight Against COVID19

Hong Kong's Airport Authority has implemented the latest technology, including disinfection channels, antimicrobial coating and autonomous cleaning robots, at Hong Kong International Airport (HKIA) to protect passengers and airport staff from COVID19 infection.

HKIA is the world’s first airport where “CLeanTech”, a full-body disinfection channel facility, is being trialled in live operation.

People using the facility will have a temperature check before entering an enclosed channel for the 40-second disinfection and sanitizing procedure.

The interior surface of the channel is equipped with antimicrobial coating which is designed to remotely kill virus and bacteria on human bodies and clothing by using the technologies of photocatalyst and “nano needles”. Sanitizing 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.

The airport is also testing the application of an 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.

Autonomous cleaning robots are currently being deployed to ensure thorough disinfection of public areas and passenger facilities.

 The Intelligent Sterilization Robot, equipped with ultra violet light sterilizer and air sterilizer, is deployed round-the-clock in public toilets and key operating areas in the terminal building.

 The robot can move around autonomously and sterilize up to 99.99% of bacteria in its vicinity, including both the air and object surfaces, in just 10 minutes.

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.”
