General 1.1 This document refers to the technical requirements and specification of Gantry" X-Ray container scanning system. 1.2 The system will include all auxiliary and supporting elements required for the proper performance, operations and functioning of the scanner taking into account safety requirements, whether detailed or not in these specifications or accompanying tender documents. 1.3 Scope of Supply This document together with its appendices defines the system tender supply requirements, which include, but are not limited to: Design Fabrication/Assembly Supply and shipment Installation and erection, including connection to the electrical / communication network Start-up, testing and running in Maintenance/warranty services ensuring the specified availability and reliability Receipt of required permits and approvals from the Israel Ministry of the Environment Protection and other relevant Israeli authorities. 3

4 2. Site Operational Concept 2.1 Location: The system will be installed at the Allenby Bridge Border crossing and operated by Israel Tax Authority/Customs. 2.2 Operational flow process The truck loaded with cargo will enter to the Allenby Bridge Border crossing and will go through Border entrance procedures After getting all approvals the truck driver will be directed by border personnel to the Customs scanning site Truck traffic into, through and out of Customs Site will be directed and monitored by Site's Command and Control (SCC) subsystem as defined hereby Site Check-In Station (CIW) The truck will approach the check-in station, equipped with an LPR system to automatically identify and record the truck license plate number (Arabic Script). Shipment Identification, being part of site's command and control (SCC) system, will be automatically recorded and input into the system, by means of Truck/Vehicle License Number - Shipment ID This shipment ID, uniquely identifying the current shipment will serve by means of LPR system to monitor cargo traffic in the site (from entrance through screening, manual search processes until exit from site) Check-in operator confirms shipment's documents, inputs the Customs ID (manifest numbers (one or more)) into the command and control system that links cargo data with the specific truck number According to a priori Customs instructions (Customs computer) the operator directs the driver to the next station according to the designated inspection, one of the following: a. R : X-ray only (to the pre-scan parking lot) b. RD: X-ray + Material discrimination (pre-scan parking lot) c. M : Manual (manual area) d. RM : X-ray + Manual e. E : Exit 4

5 The SCC system, at CIW, will enable on site change of pre-defined inspection; for example: sending the shipment to radiography after manual inspection or adding manual inspection After documents confirmation the SCC will issue a unique number that links the shipment to the specific truck and later on to the scanned image of the cargo The SCC will automatically produce an ID tag that carries the same unique Inspection ID code (produced by facility database and identifying uniquely the present inspection with unique relation to customs ID). This tag will be used to control, check and monitor each specific process for every shipment inspected The system prints the tag, used as a "Driver Card" that will be handed to the driver Driver's card includes the following details: Date and time Inspection ID Truck license plate number Designated Inspection type (R, RD, M, RM, E) Queue number for the relevant inspection Equipment at the check in station Command and control workstation SCC (Hardware & Software, interface to radiography) LPR system readers Driver's tag printer Rising arm barriers Public address. 5

6 2.2.5 Pre-scan Parking Lot The driver waits inside the truck's cabin at the pre scan parking, until his card number appears on the electronic message board The driver proceeds with the truck into the radiography tunnel according to the marked lane and will stop the truck at the designated stop point When the truck enters the "screening tunnel", truck's license plate number will be acquired by the LPR system as part of site's command and control system The second truck in waiting in the queue will go through the same procedures It is possible that only one truck will be scanned at a time with low operational volume Equipment at Pre-scan Parking Lot (SCC) Electronic board displaying queue numbers (Arabic and English script) x-ray Screening The shipment will be admitted after the readers at the entrance to Radiography installation verify the shipment ID (LPR system) The drivers will leave the trucks, with their driver cards, and continue to the driver's waiting room In the waiting room each driver must insert his card into a card reader in order to confirm that the driver/drivers left the radiation tunnel and are inside the waiting room The card reading process will operate as an interlock for activation of the x-ray system The door of the driver's waiting room will be connected as an interlock for the x-ray system The radiography system operator, after verifying (by means of the Driver's tags) that the drivers are in a safe place, will activate the installation, following the specific instructions, and produce a radiograph of the shipment. Control system will identify the inspection ID number of the shipment and relate it to the radiographic image received from the radiography installation. 6

7 As soon as radiography has been completed, the drivers will return to the truck and drive the shipment / truck to the Pre-clearance Parking Lot The radiographic image of each shipment inspected will be part of shipment database created at the check-in SCC Equipment in screening tunnel) LPR readers Driver's Tags reader (Radiography system interlock) Image analysis The Image Analyst Workstation (IAW) will display the radiographic image on one screen, along with all the relevant data originated at the check-in workstation, on a second screen and the Custom data on the third screen After analyzing the image the operator will reach one of the following two conclusions: Cleared - The shipment is cleared of any suspicion Suspicious - There is a suspicion; the shipment will not be cleared Clearing the shipment by the analyst (entering the result into Radiography command and control system) will update: The site command and control (SCC) system - automatically The customs computer operator's input In case the analyst decision was: Suspicious then the shipment is directed to manual inspection (M). The file, including radiographic images will be automatically transferred to the Manual Recheck workstation at the manual inspection site Pre-clearance parking lot The driver/importer/customs agent will be notified, regarding radiography results, by means of lighted board in front of the parking lot, and accordingly directed by the traffic control to exit gate (if cleared) or to manual inspection if required SCC Equipment Electronic board displaying truck's destination (Arabic, English, Hebrew letters): Exit 7

8 8 Manual

9 2.2.9 Manual checks Area Shipment arriving at the manual area either as result of a priori planned inspection directly from the check-in or as result of the radiography inspection, will be admitted by reading the driver s tag (given to the driver at the check-in process) The driver will be sent to the waiting room Reading the driver s tag allows the link to system data base containing shipments data: custom's, scanned / keyed- in during the process in the check-in, radiography images, etc Shipments data and x-ray images are displayed at the Recheck workstation, including image analyzer remarks and annotations At the end of the manual inspection, the inspector will input his results into the command and control system. The SCC will be updated by the relevant data through required interface resulting in one of the following: The shipment is cleared - Directed to exit gate The shipment is not cleared Equipment at Manual Area Recheck image analysis workstation Site Command and Control system (SCC) workstation Driver's tag readers Two (2) Electronic boards - displaying each shipment status and destination (one near operators room and the other in drivers waiting room) using Arabic, English, Hebrew letters Check-out workstation After clearance as result of the radiographic inspection or completion of the manual inspection, if required, the driver/importer/customs agent will be notified it s destination and directed to exit the site through the exit gate At the exit gate LPR readers acquire the approaching truck, site control system (SCC) verifies the shipment was cleared and permitted to exit If shipment clearance confirmed the gate opens automatically Equipment at Exit gate Check-out workstation (SCC) LPR readers Drivers tag Reader (used as backup). 9

The Interlock System will operate at all times even when the Radiography installation is not operating. When any aperture whatsoever is opened at any time, indications will appear in the System Operator workstation. Radiography system activation will be enabled only after safety confirmation of the operator of the radiography installation CCTV The radiation tunnel will be surveyed at all times by a CCTV system The CCTV will cover all the volume of the tunnel in a way that will enable identify a person in the tunnel. 32

33 The CCTV system displays will be located in the operator workstation on separate screen It is possible to use split screen for several cameras. The size of each camera on a split screen will be at least 10" DVR All cameras will be connected to a DVR system that will save the data in FIFO for at least 1 week The DVR will have the capability to export data to a known format (MPEG, AVI, WMV etc.) 6.17 The proposal will include a detailed scheme of the tunnel with the cameras locations, angles of coverage and technical specification The final approval for the CCTV system will be during DDR Using hardware only, the Interlock System will prevent the operation of the Radiography System when any opening leading to the radiation - exposed zone is open. The system will immediately stop the operation of the radiation source when the said opening is opened during radiation source operation The x-ray safety system will insure safe access to the restricted area using, in addition to the CCTV system, the following elements: Emergency stops Emergency stop pull-cords Sensors (for external doors) Warning lights Sirens Door interlock (switch) Beacons for X-ray measure, with automatic siren; Service switch Public Address 33

34 6.21 The above elements will be connected to Radiation Safety System Controller In addition the CCTV inside the tunnel will activate also as an interlock i.e. if one of the CCTV cameras is fault no x-ray will be authorized The controller will gather all safety information and accordingly authorizes or not the functioning of the x-ray. Controller output will be graphically displayed at the following positions; Operator workstation console Shift supervisor (at the Radiography building) 6.24 The permitted dose of radiation in the protected zone will not exceed (half) 0.5 µsv/h (0.05 mr/h) at any point, at a distance of 10 cm from the installation. Maximum Dose Rate in Operators working area or in the environment will not exceed 0.5 µsv/h The measurement shall be taken during normal operation of the installation during x-ray irradiation of a full container by source operating at maximum capacity In all parts of the zone exposed to radiation, audio and visual warnings will be installed which will give warning of a radiation system on Stand By mode and/or of emission of radiation. The coverage level of these warnings will be 100% In all areas exposed to radiation, emergency cutouts will be installed. These cutouts, operated by hardware alone, will immediately stop the emission of the radiation source In all areas exposed to radiation, an intercom system will be installed to enable contact with the operator of the Radiography installation All doors (apart from the external doors to the Radiography tunnel used by trucks) shall be equipped with special locks, each with only one key to open it. No master keys for these doors will be allowed on the installation. 34

35 6.30 The doors shall be opened from the outside only by this key. The doors may be opened from the inside by means of an emergency (panic) lock. It will not be possible to slam the door shut without the key Public Address System (PA) The system will be equipped with a PA system that will be audible throughout the restricted zone and the surrounding area PA system announcements can originate either from the operator s room or check-in station. 35
