  • Hold one can of Callington Top of Descent, start spraying from the back of the aircraft moving forward, keeping a steady walking pace.
  • Can(s) should be kept at arm’s length and directed away from passengers and towards the ceiling and closed overhead lockers.
  • When one side of the aircraft is complete, switch aisles, spraying all the way until you reach the rear of the aircraft.
  • 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.


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.
