Check-in baggage screening process at CSMIA

Step 1 – Passengers handover their Check-in bag at the airline counters. The airline representative sticks a barcode tag on the bag

Step 2 – The bag goes through an X-Ray, one level down, transported on blue conveyor belts

Step 3 – Eight X-Ray machines scan each bag and send it off. The In-Line Security team member receives the scanned X-Ray image and within 20 to 30 seconds he decides if the bag is clear to go ahead. CCTV cameras track each bag during this entire process

Step 4 – Once cleared by In-Line Security team member, the bags go through vertical separation. All the cleared bags are dropped down to a green conveyor belt whereas the suspicious bags go to the red line

Step 5 – The bags on the red belt pass through another round of screening by In-Line Security team members. If found suspicious, the owner is contacted and informed about the prohibited items in the bag which resulted in rejection

Step 6 – If the passenger is present at the airport, he/she must be physically present when the bag is opened. After the removal of prohibited items by In-Line Security team members, the bags are once again scanned and if cleared they join the remaining bags on green conveyor belt

– If the passenger is present at the airport but there is little time left for the flight to takeoff, then the airline representative will take the passenger to a dedicated facility from where the passenger via CCTV and Video Screens can see the prohibited item being removed from the bag by In-Line Security team members. After the removal of prohibited items, the bags are once again scanned and if cleared they join the remaining bags on green conveyor belt

– If the passenger has left the airport, he/she must give authorization to the respective airline staff to open the bag in presence of the In-Line Security team members and remove the prohibited items. In this case, passengers must wait till the respective airline sends the bag back to the destination

Step 7 – The bags travelling the green belt get on the tilt-trays belt, which tilts them into the final conveyor belt

Step 8 – The final conveyor belt that contained all the luggage dropped by the auto-separation belt

Step 9 – Porters load the bags into a container wagon and drive off to the aircraft.
