Robots Recruited to Keep Hong Kong Passengers Safe

Hong Kong’s Airport Authority (AA) is using enhanced cleaning technology, including robots and body disinfection booths, to protect passengers and staff from Covid-19.

Hong Kong International Airport (HKIA) is the world’s first airport to trial CLeanTech. After passengers and staff receive a temperature check, they enter the enclosed booths for a 40-second disinfection procedure.

The booths are equipped with antimicrobial coating, which remotely kills viruses and bacteria on human bodies and clothing through photocatalyst and nano needle technology. Sanitising spray will also be applied for quick disinfection.

Pilot tests are also being held for the application of antimicrobial coating on high-touch surfaces in passenger facilities, including smart check-in kiosks, baggage trolleys and bathrooms. Trials are slated to be complete this month. The AA will then consider implementing it as a long-term disinfection procedure.

In addition, Intelligent Sterilization Robots are being deployed to disinfect the airport’s public areas and passenger facilities.

The cleaning robots are programmed to move without constant human direction. They can use UV light and air sterilisers to sterilise up to 99.99 per cent of bacteria in its proximity, including surfaces and surrounding air, in about 10 minutes.

The terminal’s public toilets and key operating areas are already being serviced by the robots round-the-clock.

Steven Yiu, AA deputy director-service delivery, 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.”
