Preventing the Spread of Coronavirus Disease 2019 (COVID-19) Guideline for Airlines

Eighth Edition




In order to continue efforts in implementing routine COVID-19 prevention protocols, reinforce various measures aimed at preventing “disease importation and domestic resurgence”, and tighten measures aimed at curbing “virus spread via both human beings and cargo”, this eighth edition of Preventing the Spread of Coronavirus Disease 2019 (COVID-19) Guideline for Airlines is developed, taking into account of the changing international epidemic situation, virus mutations and the efforts in the establishment of an immune barrier among front-line personnel.


1. Assessment of Flight Risks and Differentiated Management


1.1 Risk Assessment of Domestic Flights


1.1.1 In principle, domestic flights are no longer classified into different risk levels; instead they are subject to routine prevention and control measures.


1.1.2 In case of regional epidemic rebound at places where domestic passenger flights originate, different prevention and control measures should be taken based on the different levels of response made by local governments to public health emergencies or on other relevant requirements. The details are as follows:


1.1.2.1 Measures in line with the prevention and control requirements for high-risk international/regional flights should be taken if local authority activates a level-I emergency event response.


1.1.2.2 Measures in line with the prevention and control requirements for medium-risk international/regional flights should be taken if local authority activates a level-II emergency event response or there are high-risk areas in the city of origin.


1.1.2.3 In other circumstances, measures in line with routine domestic prevention and control requirements should be taken.


1.1.2.4 Places of origin should be defined as prefecture-level cities (regions) or above.


1.2 Risk Assessment of International/Regional Flights


1.2.1 International/regional flights are subject to classified and differentiated management, with differentiated prevention and control measures implemented with respect to individual crew member protection, in-flight service and aircraft environmental hygiene management.


1.2.2 The risk levels of international/regional passenger flights will be determined based on a comprehensive rating of indicators such as epidemic situation at the points of origin, flight distance and passenger load factors. See Attachment 1 and 2 for details of rating methods.


1.2.3 Among indicators for risk assessment of international/regional passenger flights, epidemic situation at the points of origin and flight distance shall be rated based on actual situations; passenger load factors shall be rated by the planned load factors if the flights are subject to restricted load factors due to epidemic situations at points of origin. Refer to Attachment 2 for details of planned load factors.


1.2.4 The risk levels of international/regional cargo flights will be determined based on a comprehensive rating of indicators such as epidemic situation at the points of origin, type of cargo carried and the temperature at the point of origin/destination. See Attachment 3 for details of rating methods.


1.2.5 Flight risk levels shall be subject to real-time adjustment according to epidemic developments.

Crew members’ quarantine should be carried out by referring to the latest edition of COVID-19 Prevention and Control Program issued by the National Health Commission, taking into account of the specificity of crew members’ working schedules, and following the guidelines as follows.


7.1 Crew Members Quarantine Program


7.1.1 If any crew member shows such symptoms as fever, dry cough, fatigue, sore throat, impairment of smell (taste) and diarrhea during off-duty hours, and has a history of epidemiology (such as a history of living and traveling in high-risk countries/regions and of having contacts with suspected, confirmed or asymptomatic cases), he/she should be handled in accordance with the requirements in the COVID-19 Prevention and Control Program. Crew members who performed duty on the same flight on the day symptoms developed or during the previous 2 days and who had close and unprotected contact with him/her within the past 2 days should be instantly put under centralized quarantine.


7.1.2 If any crew member shows such symptoms as fever, dry cough, fatigue, sore throat, impairment of smell (taste) loss and diarrhea during the duty hours, he/she should cease performing his/her duties immediately as long as flight safety is not compromised. It is recommended to put him/her under quarantine in the cabin emergency quarantine area and avoid his/her close contact with other crew members. After the flight has landed, a special vehicle should be sent following the deplaning of passengers and other crew members, carrying him/her to a designated medical facility for examination. Other crew members should be quarantined as per 7.1.1.


7.1.3 Where any passenger on board a domestic flight shows such symptoms as fever, fatigue, dry cough, sore throat, impairment of smell (taste) and diarrhea, the crew members who have provided in-flight services for the symptomatic passenger should be under centralized quarantine after the flight has landed. Other crew members do not need to be quarantined for the time being. If the crew members having direct contact with the passenger have been personally well protected throughout the journey in accordance with the prevention and control measures laid down in this Guideline, they may be exempted from quarantine as close contacts. All crew members are required to monitor their health condition and report promptly any abnormalities that may arise.


7.1.4 Where an airline has received a message of confirmation from local disease control or quarantine department that a domestic flight operated by the airline did carry confirmed, suspected or asymptomatic case(s), the crew members involved should be quarantined as per 7.1.3.


7.2 Centralized Quarantine Measures for Crew Members


7.2.1 A special vehicle should be dispatched to carry crew members to a quarantine point to avoid contact with other people excluding the driver.


7.2.2 Crew members under quarantine should live in separate rooms, and must not leave the room except under special circumstances (and with the permission of the medical observation staff). They shall not come into contact with others under quarantine.


7.2.3 Crew members under quarantine should dine alone in their own room, and food should be delivered without any physical contact. No one other than the essential staff shall be allowed to enter the rooms where crew members are quarantined.


8. Management of International/Regional Flight Crew Members Stationed Abroad


During their stay abroad, crew members should enhance their prevention awareness, be mindful of their personal protection to avoid the risk of infection, and pay close attention to their health status.


8.1 During their stay abroad, crew members should wear personal protective equipment except in their own hotel room, and avoid close contact with others without effective protection.


8.2 While staying abroad, crew members should, as a minimum requirement, wear a medical surgical mask or KN95/N95 mask, goggles, disposable medical rubber or nitrile gloves. While staying in high-risk countries (with the prevalence rate exceeding 500 per one million people), they should wear protective clothing and KN95/N95 masks in addition to meeting the above requirements, and if they are unable to wear protective clothing due to special requirements of the local customs or border inspection authorities, they can wear disposable protective clothing with equivalent protective effect instead.


8.3 Except during their trips between airport and hotel, crew members must be strictly placed under closed-off management during their stay in the hotel. They must not go out or allow anyone to enter their rooms. Where the overseas hotel is shared by people other than the crew members, the crew members must not leave their rooms after check-in until they leave the hotel for the return flight.


8.4 Crew members should closely monitor their own health status, and report their body temperature and abnormal symptoms (fever, fatigue, dry cough, sore throat, olfactory (taste) loss, diarrhea, etc.) on a daily basis. Any abnormalities that may arise should be reported immediately. The pilot-in-command or chief flight attendant is responsible for reporting crew members’ health status and their activities to the airlines on a daily basis and recording such information for future reference.


8.5 When waiting at an overseas airport and going through customs clearance for entry, crew members should wear personal protective equipment, keep a distance of more than 1 meter, avoid mixing with passengers as far as possible, and avoid unnecessarily taking off of protective equipment. When clearing the customs, they should carry with them sanitizers and place in advance documents that need to be verified in a dedicated user-friendly transparent bag. They should disinfect the bag’s surface in time upon the completion of verification process and sanitize their hands immediately.


8.6 Crew members should be carried by dedicated vehicles, and should avoid sitting in the co-driver area. Vehicles should be cleaned, disinfected and ventilated prior to and after each ride, with enhanced disinfection for, in particular, those frequently touched surfaces such as door handles, seat armrest and railings in the vehicle.

1.4.2 Lavatory: from the heavily contaminated areas to lowly contaminated areas, disinfection in lavatory should be progressed as follows: toilet bowls, waste bins, sinks, wall panels, door surfaces, doorknobs, ashtrays (if installed), and latches.

1.4.3 Galley: from upper places to lower places and from outside to the inside, ovens, water boilers, coffee makers, galley itself, lockers/drawers, and waste bins.

1.5 Disinfectants

Aircraft cleaning and disinfectant products should be issued with an airworthiness approval to avoid damage to aircraft components. The following disinfectants are recommended to be used, at a concentration set out in product users’ manual.

As far as preventative disinfection is concerned, it is recommended to use compound quaternary ammonium salt, double-chain quaternary ammonium salt, or chlorine-containing disinfectant. Effective concentration of chlorine should be within the range of 250mg/L-500mg/L, with a reaction time of 10 minutes.

2. Operating Procedures for Preventative Disinfection in Cargo Hold

2.1 Ordinary spray disinfection or aerosol spray disinfection shall be used. Spray disinfection is suitable for the disinfection of object surface, and aerosol spray disinfection is suitable for disinfection of air and object surface. While spray disinfection is performed, the surface of the cargo hold shall be all moist.

2.2 The method of thorough disinfection should be used. Disinfectants should be sprayed from the ceiling to the floor and from the left to the right. Disinfection workers should spray and move backward at the same time, disinfecting the cargo hold in the following sequence: door, wall and floor. Finally, the floor should be sprayed again.

2.3 It’s recommended to use double-chain quaternary ammonium salt or compound quaternary ammonium salt as disinfectants, with the reaction time being the same as that of preventive disinfection in cabin. Attention should be paid to the selection of disinfectants that are not corrosive to the exposed carbon steel parts in the cabin. If it is impossible to determine whether the selected disinfectant is corrosive to carbon steel, the key parts made of carbon steel should be avoided in the disinfection operation.

2.4 After the disinfection is completed, cargo hold doors should be opened to remove the residual disinfectant particles floating in the air.



Appendix 2

Operating Procedures for Aircraft Concurrent Disinfection

Aircraft should be disinfected concurrently according to the following procedures in Emergency Medical Equipment Installation and Training for Large Transport Aircraft (AC-121-102R1 issued by CAAC):

1. Wear personal protection equipment.

2. Prepare disinfectant: Put one surface disinfection tablet into 250-500ml clean water to make a 1:500-1000 disinfectant.

3. Cover the respiratory secretions, blood, vomit, excretions and other contaminants evenly with absorbent disinfectant for 3-5 min to enable them to be solidified.

4. Shovel the coagulated contaminants with portable pickup shovels into biohazard waste bags.

5. Sterilize twice the contaminated area with pre-prepared disinfectant, make sure disinfectant stays on the contaminated surface for 3-5 minutes, then wash the area twice with clean water before drying the area with towels. Put those towels and other used disinfectants into a biohazard waste bag.

6. Disinfect hands before removing protections in the following order: take off protective suits (aprons), gloves, apply skin disinfection wipe for hand disinfection; then take off goggles, facial masks, and finally apply skin disinfection wipe to clean hands and other parts of the body that may have been exposed to contaminants.

7. Put all used protection gears and contaminated items into biohazard waste bags, seal the bags, and stick a “Biohazard Waste” label close to the seal.

8. Keep the sealed biohazard waste bags in a proper place temporarily to prevent them from being lost, damaged or contaminating meals on board.

9. Inform relevant ground handling agents at the destination to make preparation as required.

Appendix 3

Operating Procedures for Aircraft Terminal Disinfection

1. Aircraft Cabin Terminal Disinfection

1.1 After all occupants get off the aircraft, close cabin doors, and set the air conditioner to its maximum capacity to allow at least one complete cycle of ventilation in the cabin area.

1.2 Once the ventilation is over, the sitting area of the passengers with suspicious symptoms and lavatory should be disinfected before proceeding with the thorough terminal disinfection from periphery to center and from top to bottom.

1.3 After disinfection, the passenger cabin should be cleaned in accordance with the post-flight cleaning requirements.

1.4 For a stop-over flight carrying suspected cases, as a first move, its sitting areas should be disinfected during the stop-over, and after end of the flight, a terminal disinfection shall be conducted covering the whole cabin.

1.5 Air conditioning system shall be turned off during the disinfection and the cabin shall be fully ventilated after disinfection.

2. Aircraft Cargo Hold Terminal Disinfection

2.1 When animal remains or suspicious contaminants of a contagious nature are found in the cargo hold, the contaminated area in which the animal remains or the contaminants were should be disinfected and cleaned as the first step, followed by a thorough disinfection of the remaining areas of the cargo hold.

2.2 Thorough spray disinfection should be conducted. Disinfection should be performed from upwind to downwind and from top to bottom.

2.3 Before disinfecting the inside area of the cargo hold, spray around the door, close the door, enter into the cargo hold, and spray on the floor while moving forward till the whole floor is sprayed before disinfecting other areas of the cargo hold.

2.4 Disinfect the cargo hold by spraying disinfectant from left to right and vice versa, and then spray the cargo hold wall from top to bottom. The amount of disinfectant sprayed should not exceed the amount of the liquid that can be absorbed (the maximum amount of disinfectant the surface can absorb).

2.5 Upon completion, disinfect the cargo hold floor once again by spraying while moving backward. After returning to the ground along the ladder, disinfect the ladder by spraying.

2.6 Air conditioning system shall be turned off during the disinfection and the cargo hold shall be fully ventilated after disinfection.

3. Disinfectant

Aircraft cleaning and disinfection products should be issued with an airworthiness approval. During terminal disinfection, the passenger cabin should be wiped while the cargo hold should be wiped or sprayed with disinfectant. Liquid concentration should be in line with what’s specified in product users’ manual.

It is recommended to use chlorine-based disinfectant for terminal disinfection. The effective concentration of chlorine should be 1000mg/L, with a reaction for 30 minutes. Attention should be paid to the selection of disinfectants that are not corrosive to the exposed carbon steel parts in the cabin. If it is not possible to determine whether the selected disinfectant is corrosive to carbon steel, the key parts made of carbon steel should be avoided in the disinfection operation.
