The Effectiveness of Metal Detectors Installation in LRT and MRT Stations; Government Response to Safety and Security

Abstract

A metal detector is an electronic instrument which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects. If the sensor comes near a piece of metal, this is indicated by a changing tone in earphones, or a needle moving on an indicator. Usually, the device gives some indication of distance; the closer the metal is, the higher the tone in the earphone or the higher the needle goes. Another common type is stationary "walk-through" metal detectors used for security screening at access points in prisons, courthouses, and airports to detect concealed metal weapon on a person’s body. This study aims to set the perception of security guards and passengers in LRT and MRT stations of the effectiveness of metal detectors installed in the selected station. The study used the descriptive method design for the investigation to gather information about the effectiveness of metal detectors installation in LRT and MRT stations. The study also focuses on the government’s response to safety and security. According to Dr. Y. P. Aggarwal (2008), descriptive research is “devoted to the gathering of information about prevailing conditions or situations for description and interpretation. This type of research method is not simply amassing and tabulating facts but includes proper analyses, interpretation, comparisons, identification of trends and relationship”. The respondents are described according to their demographic profiles. The majority of the respondents were from the age bracket of 21-25 years old: 56% were male, 64% were single, and 50% were college level. There are assessments about the effectiveness of metal detectors installed in selected LRT and MRT stations. There were also problems encountered in LRT and MRT stations in using metal detectors and there are recommendations to maintain the operation of metal detectors in LRT and MRT stations. The results of this study can be used for the improvement of the effectiveness of metal detectors installed in selected LRT and MRT stations. It can also be used as a basis to enhance the processes of the Government on the safety and security methods appropriate to LRT stations. The study is believed to inform the public about the effectiveness of metal detectors in terms of crime prevention.
