2.1 | X-ray machine- an equipment which provides a fast and convenient way of seeing through objects without the need to unpack or damage them by bombarding them with gamma ray. |
2.2 | WTMD (Walk Through Metal Detector)- a machine which has a coil in the side of the arch-way to which the person being screened passes. It generates a rapidly changing magnetic field when a person has a metallic object in his body. |
2.3 | HHMD (Hand Held Metal Detector) – a hand machine which has a changing magnetic field which induce an electric current to flow in a conductor. In turn this current produces its own magnetic field which detects the position of the metal in the body of the person. |
3.a | X-ray machine should be turned on and tested at least an hour every time its daily use or at least an hour before the airline counter opens for the day’s business. This shall be recorded in OTS form # 7. |
3.b | At least one (1) test shall be made utilizing the “step wedge testing kit” to ascertain sharpness, clarity and contact of images projected in the monitor. The result of each separate test shall be correspondingly recorded in the OTS form # 8. |

4.c | These forms shall be accessible only to authorized individuals as determined by the OTS. |
4.d | In case of malfunction, the screening supervisor shall inform the airport technician for appropriate action. |
4.e | Each unit shall be turned off when its operation ends for the day. |
5.a | Each HHMD shall be tested for its operational condition using three metal density configurations hidden in the body of a person. |
5.b | Each test result shall be recorded properly in OTS form # 9. |
5.c | These forms shall always be available for inspection of CASS, OTS QC Inspectors in the work place. |
5.d | Only fresh batteries shall be used to operate the HHMD. In case of malfunction, the screening supervisor shall inform the airport technician for appropriate action. |
