In response to the COVID-19 pandemic, the CAAC (Civil Aviation Administration of China), the aviation authority responsible for China, has released a guideline for airport management to help prevent the spread of coronavirus in airport settings. Within the guideline, the CAAC highlights chlorine dioxide as a daily preventative multipurpose disinfecting agent for air disinfection and ventilation cleaning and for disinfection of high-touch surfaces such as kiosks and check-in countertops, crowded places, elevator buttons, handrails, etc. Chlorine dioxide is also an adopted measure for when suspected or confirmed cases are present and/or passengers are displaying COVID-like symptoms; chlorine dioxide, in this case, is sprayed throughout the terminal and on terminal surfaces, especially densely packed passenger areas and contaminated areas.
