People who work with the steam boilers in palm oil mills are vulnerable to accidents, notably to explosions, whenever failures of any kind occur during their operation.
This cross-sectional study was conducted in palm oil mills to determine the knowledge, attitude, and perception (KAP) concerning the risk management of steam boilers among workers in palm oil mills.
A total of 50 workers who were working with steam boilers and/or involved in managing the operation of steam boilers with at least three years of working experience in the palm oil industry were purposively sampled. A self-administrated questionnaire consisting of four main parts - socio-demographic and occupational information, knowledge, attitude, and perception of the risk management of steam boilers was distributed. The knowledge, attitude, and perception were calculated based on a Likert-type scale.
This study found that 56% of boiler workers had a good level of knowledge (mean score = 77.22±19.6), 72% had a good attitude toward risk (mean score = 83.17±5.85), and 64% had a good perception of risk (mean score = 79.50±11.22). The prevalence of accidents was 16%, and, for near misses, it was 24%. The cause of the reported accidents was largely attributed to carelessness, specifically at 80%. Apart from that, there was a positive association (χ2 = 6.56; p = 0.010) between attitude and accidents.
This study found that the workers had good KAP levels of risk management of steam boilers in palm oil mills. However, there is a need for the employers to revise the training of workers and ensure its effectiveness in heightening the awareness of risks and accidents despite the high level of KAP.
在棕榈油厂操作蒸汽锅炉的工人容易发生事故，尤其是在操作过程中出现任何故障时发生爆炸。
本横断面研究在棕榈油厂进行，以确定棕榈油厂工人对蒸汽锅炉风险管理的知识、态度和认知（KAP）。
共有50名操作蒸汽锅炉和/或参与管理蒸汽锅炉操作且在棕榈油行业至少有三年工作经验的工人被有目的地抽样。发放了一份自我管理的问卷，问卷由四个主要部分组成——社会人口和职业信息、知识、态度以及对蒸汽锅炉风险管理的认知。知识、态度和认知基于李克特量表进行计算。
本研究发现，56%的锅炉工人知识水平良好（平均得分=77.22±19.6），72%的工人对风险态度良好（平均得分=83.17±5.85），64%的工人对风险认知良好（平均得分=79.50±11.22）。事故发生率为16%，未遂事故发生率为24%。报告的事故原因主要归因于粗心大意，具体占80%。除此之外，态度与事故之间存在正相关（χ2=6.56；p=0.010）。
本研究发现，棕榈油厂工人对蒸汽锅炉风险管理的KAP水平良好。然而，尽管KAP水平较高，但雇主仍需修订工人培训并确保其在提高风险和事故意识方面的有效性。
