This test defines the ability of the system to distinguish and display objects, which are close together. The CTP has 16 copper gratings at right angles to each other. A tick in the log sheet will indicate that gaps in the gratings are visible. 6. THIN METAL IMAGING: (Test No 6). 6.1 The requirement is to view image of steel O.lmm thick. This tests the machine's ability to image thin metal. A number of thin metals strips of various thicknesses are placed in a row. 7. METHOD: 7.1 The CTP should be certified by a Government Test lab for dimensions and material composition. The CTP is to be used as a quick routine test carried out daily to ensure that equipment is working properly and satisfactory image is obtained. The results of the tests should be recorded. 7.2 The CTP should be placed on the belt and passed through the belt atleast once in a day before the baggage is screened or after the X-Ray equipment is switched on to ensure that the equipment is working properly. If the image is satisfactory the equipment may be used. 7.3 The CTP may be viewed by using image enhancing facility till the operator is satisfied that the machine is working properly. The optimum position of CTP on the belt will depend on X-Ray source and detector arrangements. In case of dual view systems atleast one view should pass CTP. This may be ascertained from the service engineer, if need arises. 8. RESULTS: 8.1 The results of test should be recorded giving information like date. time. machine number and type, supervisors name and other remarks. 8.2 Supervisory officer should carry out the tests once in a week and compare the results with daily test sheets.

INTRODUCTION The existing X-ray machines installed at check in area in some of the airports to screen registered baggage are in stand-alone mode and not capable of detecting 100% explosives. Stand-alone machines occupy space at departure lounges and also cause big queues, which disrupt passenger flow during peak hours. Keeping in view the security threat it is desirable that multi-level CT-EDS based in-line detection system is installed at major airports. The Inline hold baggage handling system (HBS) shall be integrated with airport baggage handling system in order to provide complete hold baggage processing and screening system All new terminals and airports constructed in future will have only HBS. The priority of installation of HBS shall be decided by Airport Operator in consultation with BCAS. 2. Conceptual System Design The system designed for multi-level screening process shall have the following features: - 2.1 Levell Level screening is to be undertaken by a CT-EDS machine with automatic explosives detection facilities. All baggage images will be referred to Level 2 with suspicious area highlighted, if any, where a certified screener will accept or reject the baggage. 2.2 Level2 2.2.1 Level 2 screening is remote workstations(s) whereby operator(s) can analyze the image generated by the Levell CT -EDS machine. The workstation is required to be equipped with enhanced imaging / manipulation systems to assist operator to diagnose the screened image. 2.2.2 100% of level-l screened baggage images should be referred to level 2. 2.2.3 Whilst the bag is being referred to level 2, it should be 'tracked' while it travels along the length of the conveyor such that its position and identity is known at all times. 2.2.4 In practice, it is usual to provide a conveying system that allows a programmable time of ur to 30 seconds to queue and process the level 2 images. 2.2.5 In case of major airports with 5 MPP A or more, airport operators shall install level 2 B so as to ensure that Level-3 is not overloaded. In case of bigger airports (higher passenger density airport), a workstation 2B shall be introduced for longer time analysis. In this instance, there will be enhanced image manipulation capabilities; usually a more senior / experienced operator will view the image and have more time to interpret and take a decision. 2.2.6 In systems with multiple level 1 machines, the MUX / Matrix type set-up of several. levelland level 2 workstations will be linked together, enabling the next un-cleared level 1 image to go to next available level-2 workstation. The MUX / matrix data communication RESTRICTED Page 10 of 26  RESTRICTED shall enable any of the Level 1 X-ray systems to send rejected bag images to any of the Level 2 workstations. The proposed MUX / matrix scheme must be flexible enough to accommodate future expansion. In all cases, any bag considered suspect by the operator are to be flagged and routed automatically to Level 3. 2.2.7 Cleared bags shall proceed to the baggage make -up area. 2.2.8 In bigger airports any bag not cleared within a pre-determined time by the level 2A operators, are considered 'time-outs' and automatically forwarded to level 2B. In other cases it should be forwarded to level 3 from level 2. In addition any mis-tracked or unscreened bags on the conveying system are defaulted to the level 3 area. 2.3 Level3 2.3.1 There are several technologies available for level 3 screening, and the selection usually depends upon BCAS regulations and / or budget constraints. These include: 2.3.2 A workstation may be installed at level -3 to retrieve the image created by Level - I CT-EDS. These workstations may increase as per requirement and higher density airports. 2.3.3 These workstations should be able to pull the image of the baggage created by Level-l machine by a barcode reader/ scanner. 2.3.4 A standalone Dual Energy and dual view X-BIS shall be installed at Level-3 to screen the baggage again. Screener shall rescreen the baggage at level-3 invariably. 2.3.5 Explosive Trace / Particle detection Check. The un-cleared / suspected bags shall be checked with latest explosive trace detectors by using vacuum pump / specially designed filter papers for checking the presence of explosive substances. 2.3.6 Explosive Sniffer Dogs. The dogs being the most reliable explosive detection system, it is recommended that rejected bag at level 3 be sniffed by Explosive Detection dogs. A dog shall be deployed for confirmation, once ETD gives a positive signal. The dog is to be turned over everyone hour. In an 8-hour shift, there should be minimum 2 dogs with handlers. 2.4 Level 4 2.4.1 All un-cleared / suspected bags at level 3 are to be reunited with their owners for further inspection and interview. This process is normally manual and should be done in a safe area. 2.4.2 A workstation may be installed at level-4 to retrieve the image created by Level--l CT- EDS to facilitate the physical inspection of the baggage by the security staff. Bag should be accepted or rejected on the system as well as an entry in the baggage hand over register is to be made. 2.4.3 These workstations should be able to pull the image of the baggage created by Level-l machine by a barcode reader/ scanner. 2.4.3 Any bag that is still deemed to be suspect after passenger interview. or if the passenger RESTRICTED Page 11 of 26  RESTRICTED cannot be located, are normally handled as per SOP. Once a bag is declared as threat bag, it should be shifted through conveyor belt system/ automatic lift system. 3. System Throughputs 3.1 Normally a single inline CT -EDS at Level-l should have a throughput of 400-500 bags/hour or more, as per requirement of specific airport. 4. Approval by Regulatory agent. 4.1 Approval by Internationall ~ational regulatory agency: - The CT machines deployed at Level- 1 must be certified and approved by TSA / ECAC standard 3. 5.

Services Main supply 415V ± 10% 3 Ph, 50 ± 5%Hz Note the CT-EDS machine generally requires a conditioned power supply. 29. Bag conditioning pre screening The BHS should ideally include a number of features that condition and present the bag to the X-ray in a separate, spaced and controlled manner. This should include: - 1. Check in operator discipline e.g. tie up trailing straps, use tubs as appropriate etc. 11. Window reservation techniques at check- in Icollector conveyor 111. Use of zoned belts at transfer in feeds IV. Automatic baggage separation v. Spacing and pitching of bags to suit the needs of the X-ray machine. VI. Over-height detection Vll. Over-length detection 30. Collector System - Window Reservation technique 30.1 This feature is applied to those instances where by automatic checks in conveyors are provided to deliver bags on to collector conveyors. 30.2 A system known as "Window Reservation" is used to control the flow of bags. Effectively, the belt on the collector conveyor is split up into imaginary zones or "windows" each large enough to accept the bag and these are allocated to check -in desks on a demand basis such that all input have equal opportunity. This reduces passenger-waiting times. and also controls the flow of bags into the handling system right from the point of in-put. 30.3 As the allocated window approaches the desk. the Dispatch conveyor will automatically start up and the bag will be transferred onto the collector conveyor. This procedure is repeated until all bags in a single transaction are released in to the system. 30.4 It is preferential to arrange the conveyor speed such that the bags are fired across the collector conveyor. This encourages the bag to lie flat and also decreases the cycle time. 3 1. Transfer In feed - Marked Belt 31.1 In those instances where bags are delivered to the HBS system via a transfer in feed line (or similar) it is much harder to control the input and flow of bags as this is operator dependent. 31.2 There should be discipline about the type of bag to be handled and also the orientation that the bag is placed onto the belt, such that it is in the most stable orientation for conveying and
