Amid the COVID-19 outbreak, CAG has taken a more rigorous approach to cleaning to ensure the safety of airport workers, passengers and visitors. For more than nine months, CAG had been testing a self-disinfecting coating named sdst, which is now used in various parts of Changi Airport. Frequently-touched surfaces such as the automated check-in kiosks, escalator and travellator handrails, trolley handles and more, are coated with a layer of sdst using a special spray gun. This self-disinfecting coating bonds to the treated surfaces and safeguards against viruses, bacteria and fungi for up to six months.
To help the Town Councils understand the science behind sdst and the proper application method for maximum effect, CAG conducted briefings for Town Council staff and conservancy workers.
