Abstract

Occupational safety and health (OSH) has been a much talked about current issue. This study focuses on occupational risk management on noise exposure in palm oil mill in Johor and Melaka, Malaysia. The objectives of this study are to identify the hazards based on perspective study among workers in palm oil mill, to evaluate workplace and personal noise exposure level in palm oil mill, and to recommend preventive measures for risk management on noise exposure in palm oil mill. The study was assessed based on validated questionnaire, workplace inspections, personal noise exposure level, and workplace noise exposure level. This study successfully carried out at six mills (excluding pilot study). A total of 306 sets of questionnaire were collected and noise monitoring was carried out at five mills. Statistical software, SPSS version 21 was used to analyse the data from questionnaire. It is found that noise is the most reported hazards among the respondents followed by dust. In addition, environmental noise exposure level result shown that the highest noise level was recorded at engine room in all mills ranges from 89.6dB to 98.2dB while sterilizer station shown lowest noise level (76.2dB – 90.8dB). Meanwhile, only one measurement recorded at engine room exceeded the permissible exposure level (90.9dB > 90dB) for personal noise exposure level monitoring. Overall, the workers in palm oil milling industry are exposing to high level of noise. Thus, it is highly recommended to increase the workers‟ safety awareness and enhance the risk management on noise exposure in palm oil mill.
