Hand sanitiser stations
Changi Airport has implemented several measures to ensure the safety of its passengers, staff, and visitors. One of the key measures is the significant increase in the number of hand sanitiser stations across the airport.
Prior to the COVID-19 pandemic, there were approximately 160 hand sanitiser stations available throughout the terminals and Jewel. However, recognising the importance of hand hygiene in preventing the spread of the virus, Changi Airport has increased the number of hand sanitiser stations to more than 1,200. This ensures that hand sanitiser is readily accessible to everyone in the airport.
These hand sanitiser stations are strategically placed at various high-contact and high-traffic areas within the airport, such as door knobs and handles, touchscreens, handrails, countertops, and railings. By providing easy access to hand sanitiser, Changi Airport encourages everyone to practise good hand hygiene, which is crucial in reducing the risk of virus transmission.
In addition to the hand sanitiser stations, Changi Airport has also enhanced its cleaning and disinfection protocols. The frequency of cleaning has been doubled, and disinfectants are now used instead of general-purpose cleaning solutions. This ensures that frequently touched surfaces are sanitised regularly, up to four times a day, to minimise the risk of viral spread.
Changi Airport's comprehensive approach to safety, which includes the widespread availability of hand sanitiser stations, enhanced cleaning protocols, and improved air filtration systems, demonstrates its commitment to providing a safe and healthy environment for all who pass through its gates. These measures are designed to instil confidence in travellers and assure them that their well-being is a top priority.

Temperature screening
Changi Airport has implemented several measures to protect the health and safety of its staff, passengers, and visitors during the COVID-19 pandemic. One of the key measures is temperature screening, which is conducted at various locations within the airport.
In addition to guest screening, Changi Airport also performs temperature checks for all staff members before the start and end of each shift. Staff members who exhibit fever or flu-like symptoms are advised to seek immediate medical treatment. This proactive approach helps reduce the risk of infected individuals coming into contact with others in the airport.
The airport has also increased the number of hand sanitisers available in the terminals and Jewel, providing over 1,200 access points for guests and staff to practice good hygiene. Changi Airport continues to advise its community to remain vigilant, observe personal hygiene protocols, and stay at home if they are feeling unwell.
Other precautionary measures implemented by Changi Airport include enhanced cleaning and disinfection efforts, particularly in frequently touched areas such as door knobs, handrails, countertops, and lift buttons. The airport has also upgraded its air-conditioning system filters to MERV-14-rated models, which can effectively remove approximately 85% of particles in the air that are smaller than the size of a coronavirus particle in a respiratory droplet. These multi-layered protection strategies help ensure that Changi Airport provides good ventilation and high-quality indoor air for all its visitors.

Cleaning and disinfecting
Changi Airport Group (CAG) has implemented enhanced cleaning and disinfecting protocols to ensure the safety of airport staff, passengers and visitors. The frequency of cleaning has been doubled across the four terminals, with a focus on frequently touched surfaces such as doorknobs, handles, touchscreens, handrails, countertops, lift buttons, and play areas. Disinfectants are now used instead of general-purpose cleaning solutions, and these surfaces are cleaned and disinfected up to four times a day. Tables at F&B outlets are sanitised after each use, and there is a heightened focus on cleaning toilets, emptying bins, and wiping sinks and countertops.
To further enhance indoor air quality, Changi Airport has upgraded its air-conditioning system filters from MERV-7 to MERV-14-rated models. These higher-grade filters can capture approximately 85% of particles in the 0.3 to 1.0 micrometre range, which is smaller than the size of a coronavirus particle in respiratory droplets. The filters are replaced regularly to ensure optimal performance, and all maintenance staff wear the highest level of personal protective equipment when handling used filters.
In addition, Changi Airport has maximised fresh air intake by fully opening dampers to increase outdoor air circulation. Ultraviolet-C (UV-C) sanitisation equipment is also being installed in Air-Handling Stations to eliminate any remaining virus traces. Portable air purifiers with hospital-grade High-Efficiency Particulate Air (HEPA) filters have been placed in more confined spaces, such as staff canteens and transfer holding areas, to further mitigate the risk of airborne COVID-19 transmission.
The airport has also increased the number of hand sanitisers available in the terminals and Jewel, providing over 1,200 hand sanitiser dispensers for added convenience and protection.

Air quality
Changi Airport has implemented several measures to improve air quality and ensure the safety of its passengers, visitors, and staff amid the COVID-19 pandemic.
Firstly, they have upgraded the air-conditioning system filters across the passenger terminals from MERV-7 to MERV-14-rated filters. These higher-grade filters can effectively capture and remove approximately 85% of particles in the air that are 0.3 to 1.0 micrometres in size, which is smaller than the size of a coronavirus particle in respiratory droplets. To maintain the efficiency of these filters, they are replaced regularly, every one to two months, and properly disposed of by maintenance workers wearing personal protective equipment.
Additionally, Changi Airport has maximised the intake of fresh air in the air-conditioning systems by fully opening the dampers to allow outdoor air to circulate. They have also deployed portable air purifiers with hospital-grade High-Efficiency Particulate Air (HEPA) filters in more confined spaces, such as staff canteens and transfer holding areas. These purifiers further enhance the air quality by removing more than 99% of any residual particles, ensuring a low Carbon Dioxide (CO2) level of less than 500 ppm (parts-per-million). This is significantly better than the allowable CO2 level stipulated in the Code of Practice for Indoor Air Quality, providing assurance of good ventilation and high-quality indoor air for all visitors.
Other measures taken by the airport include intensified cleaning and disinfection regimes, increased availability of hand sanitisers, and temperature screening for guests and staff. These comprehensive efforts demonstrate Changi Airport's commitment to providing a safe and healthy environment for all during the pandemic.

Staff vigilance
Changi Airport Group (CAG) has implemented several measures to ensure the safety of its staff, passengers, and visitors. CAG advises its staff to remain vigilant, practice good personal hygiene, and take leave from work if they feel unwell.
To facilitate this, CAG has increased the number of hand sanitisers available in the terminals and Jewel from about 160 to more than 1,200. Additionally, temperature screening is conducted for all staff before the start and end of each shift, and staff with fever or flu-like symptoms are asked to seek immediate medical treatment.
CAG has also enhanced its cleaning initiatives, doubling the frequency of cleaning efforts and using disinfectants in frequently used areas, including door knobs, handles, touchscreens, handrails, countertops, and railings. Tables at F&B outlets are cleaned and disinfected each time they are cleared. The frequency of toilet cleaning, emptying of litter bins, and wiping of sinks and countertops has also been increased, with a focus on using disinfectants for high-touch surfaces such as toilet flush buttons, door knobs, grab bars, and dispensers.
To further protect staff, CAG has upgraded the air-conditioning system filters across the passenger terminals to MERV-14-rated models, which can remove about 85% of particles in the air that are smaller than the size of a coronavirus particle in a respiratory droplet. These filters are replaced regularly, and all used filters are sealed and disposed of by maintenance workers wearing the highest level of personal protective equipment.
By implementing these measures, CAG aims to provide a safe and healthy environment for its staff and visitors, while also adapting to the evolving COVID-19 situation worldwide.
