INVESTIGATION OF NOISE LEVELS AND RISK MANAGEMENT IN THE MACHINERY WORKSHOP AT UITM BUKIT BESI

Abstract

A noise inspection was conducted at the Machinery Workshop of UiTM Bukit Besi to evaluate noise levels and associated health risks. The study identified various noise sources and categorized them into four zones: above 115 decibel(A), 86-114 decibel(A), 82-85 decibel(A), and below 82 decibel(A). Noise measurements were taken using sound level meter applications and mapping techniques. Results showed some machines, particularly the Metal Lathe Machine and Hydraulic Shearing Machine, produced noise levels exceeding 85 decibel(A), posing significant risks of hearing damage. The inspection followed guidelines from the Occupational Safety and Health (Noise Exposure) Regulations 2019. Recommendations included implementing a hierarchy of control measures such as engineering controls, administrative controls, and personal protective equipment. The study highlighted the need for regular noise monitoring, employee education, and clearly marked hearing protection zones to mitigate noiserelated health risks in the workshop. This assessment establishes baseline measurements for ongoing monitoring of noise levels and effectiveness of control measures in protecting worker health and safety in the machinery workshoporatory setting.
