The Top of Descent spraying method is to be carried out with passengers on board, after passenger embarkation but before the overhead lockers are closed and the aircraft is pushed back for departure or on-arrival for aircrafts that were not disinsected before arrival or not disinsected correctly or as required as an additional treatment. The Top of Descent aerosol is also used for the disinsection ‘on-arrival’ for the ULD’s or Aircans.


Treatment Procedure

• The treatment is done after passengers have boarded and are seated and all service doors are closed.
• Before commencing treatment, all overhead and sidewall lockers must be opened.
• During disinsection and for 5 min after completion of spraying, the aircraft's air conditioning must be switched off or set to normal flow (not high flow) and the recirculation fans must be on.
• Hold one can of Top of Descent, start spraying from the back of the aircraft moving forward, keeping a steady walking pace at a rate of not more than one step or one row of seats per second.
• Can(s) should be kept at arm's length and directed away from passengers and towards the ceiling and opened overhead lockers.
• When one side of the aircraft is complete, switch aisles, spraying all the way until you reach the rear of the aircraft.
• Spray all galleys, including those on lower levels, and the lift access. Spray all toilets and coat lockers for 2s each. Ensure that the toilet seats and baby changing tables are up and are not sprayed. Spray all crew rest areas, avoiding the bedding, and the flight deck and cockpit for 3s each. Direct the spray away from aircraft equipment, officers and crew.
• Do NOT spray directly on exposed food, food preparation areas or food utensils.
• Spraying of cabins shall be carried out at a standard spray rate of 1g per second and based on a required coverage rate of 35g/100m3.

• Cabin crew should prepare the cabin for disinsection by opening all overhead lockers and requesting all passengers to remain seated.
• During disinsection and for 5 min after completion of spraying, the aircraft’s air-conditioning must be switched off. Recirculation fans may be left on if they are essential for operation of the aircraft but should be set at the lowest flow rate.
• Follow the same procedure as Pre-departure spraying.
• For ‘On-Arrival’ disinsection of Aircans or ULD’s, apply a full aerosol can per ULD/Aircan, spraying evenly and constantly into the space as soon as the Aircan is opened.


The applicator is responsible for ensuring that a certificate detailing the treatment is completed. For compliance purposes, the applicator must record the product serial number, located on the underside of the can. The certificate for top of descent cabin disinsection and the exhausted or partly exhausted cans must be carried onboard the aircraft and made available to an officer/inspector on request upon arrival.
