This study entitled “Level of Competency of Security Personnel in Bomb Threat: Basis for Safety Improvement” involves eighteen (18) security guards and fifty-nine (59) teachers or a total of seventy four (74) respondents from Lipa City. The researchers used the descriptive method of research, with the self-made questionnaire as the data gathering instrument. This study aimed to determine the level of competency of security personnel in bomb threat in order to formulate a program. The variables under the study include the profile of the respondents such as age, gender, educational attainment, occupation, rank, length of service and training as well as the level of competency of security personnel in dealing bomb threat in terms of Bomb Incident Plan and Bomb Threat Procedure. Furthermore, the researcher sought to answer the hypotheses of no significant difference on the level of competency of the respondents in dealing bomb threat and no significant relationship on the profile of the respondents and their level of competency in dealing bomb threat. The researcher cope up to the conclusion that majority of the teacher- respondents were 31- 40 years old, female, college graduate, with rank of Teacher III, 21-25 years length of service and no seminar attended. Majority of the security guard- respondents were 41- 50 years old, male, both High School Graduate and Elementary Graduate, with a rank of Security Guard2, 16-20 years length of service and training attended Lecture on Bomb threat Response. Majority of teacher- respondents are not aware of using bomb checklist to find out details about the caller. In addition to this, majority of the teachers and security guard- respondents are not aware of having drills/training. Majority of teacher- respondents are not aware in dealing bomb threat upon receipt of the call. Majority of teachers and security guard- respondents are not aware in the next procedures after notification of the threat in the proper authority. Majority of teacher and security guard- respondents are not aware in searching establishment. And lastly, majority of the teachers and security guard- respondents are not aware in the procedure when they found a suspicious object. On the other hand, the researcher recommended that The Explosive Ordnance Disposal Team (EODT) must issue bomb checklist and will actually explain how it will be used at the time of receiving a bomb threat. They must not conduct only fire/earthquake drill. They must also conduct a bomb threat drill for the purpose that they are aware already in times of bomb threat. Also, choose security agencies that provide training on their security guards regarding on how to respond in times of bomb threat emergency to place caller ID in school phones which may help identify bomb threat callers. Enabling voice mail and recording calls for security purposes might be a big help. The Explosive Ordnance Disposal (EOD) personnel must conduct mandatory seminars or training to determine if the security personnel’s understand and can carry out security duties. It helps security personnel in responding quickly and safely. Also conduct announced or unannounced test once a year. Those seminars or training must be supported by Local Government and Department of Education (DepEd). And also, future researchers should conduct another study which is similar with the present study.
