ABSTRACT

The main objective of the study is to determine the noise level emitted by the machinery and equipment used at a Liquefied Petroleum Gas in Melaka, Malaysia. The study also aims to determine the exposure level of noise to the employees. The machinery and equipment noise level was measured using a calibrated sound level meter. Noise level of each source was measured by pointing the sound level meter microphone at normal working distance to the source. Personal noise exposure was conducted at the shoulder of the personnel and as close as possible to the personnel’s ear. From a total of 154 noise sources points identified at three work areas surveyed, 122 points were above Action Level of 85 dBA of which 57 points had exceeded the Permissible Exposure Limit of 90 dBA. For the personal exposure monitoring, ten out of fourteen had exceeded the Action Level of 85 dBA for those working for 8 hours and 82 dBA for those working for twelve hours and one of them had exceeded the Permissible Exposure Limit of 87 dBA for those working for twelve hours. The monitored personnel have exceeded the Maximum Level and the Peak Level limit of 115 dBA and 140 dB respectively. From the study, it is concluded that further noise monitoring is needed especially when there are changes to the work process and equipment used. Also the requirement to notify the selected workers on the personal noise exposure result, actions to reduce noise level at the workplace through engineering control methods and administrative controls.
