Abstract Despite the widespread process safety management (PSM) implementation among major hazard installations (MHI) in Malaysia, an assessment on current PSM implementation maturity had never been conducted. This study aims to provide such assessment, through the utilisation of PSM elements under the OSHA PSM standard. The study first involved the measurement of PSM implementation achievement grades as well as, the development of PSM implementation related process safety maturity model and process safety assessment rubrics. Both the achievement grades and maturity model were then utilised for the assessment on PSM implementation maturity among MHI in Malaysia. Suitable recommendations for improvements in effectiveness of PSM implementation were finally proposed with reference to the assessment rubrics. From the individual PSM elements implementation assessment results, the Pre-Startup Safety Review element registered the highest representative percentage of 24 %, of MHI in Malaysia having PSM implementation maturity below the predefined acceptable maturity levels. From the overall PSM implementation assessment results, it was found that a representative percentage of 40 % of MHI in Malaysia displayed PSM implementation maturity below the similar predefined acceptable maturity levels. However, the study emphasised that future improvements to the PSM implementation maturity could be achieved through the implementation of the proposed recommendations.

马来西亚主要危险设施过程安全管理实施成熟度评估

摘要 尽管在马来西亚的主要危险设施 (MHI) 中广泛实施了过程安全管理 (PSM)，但从未对当前的 PSM 实施成熟度进行评估。本研究旨在通过利用 OSHA PSM 标准下的 PSM 要素来提供此类评估。该研究首先涉及 PSM 实施成就等级的测量以及 PSM 实施相关过程安全成熟度模型和过程安全评估指标的开发。然后利用成就等级和成熟度模型来评估马来西亚 MHI 的 PSM 实施成熟度。最后参考评估标准提出了适当的建议，以提高 PSM 实施的有效性。从个别 PSM 元素实施评估结果来看，启动前安全审查元素在马来西亚的 PSM 实施成熟度低于预定可接受成熟度水平的 MHI 中记录了最高的代表性百分比，为 24%。从整体 PSM 实施评估结果中发现，马来西亚 40% 的 MHI 显示 PSM 实施成熟度低于类似的预定义可接受成熟度水平。然而，该研究强调，可以通过实施建议的建议来实现 PSM 实施成熟度的未来改进。马来西亚 MHI 的 PSM 实施成熟度低于预定义的可接受成熟度水平。从整体 PSM 实施评估结果中发现，马来西亚 40% 的 MHI 显示 PSM 实施成熟度低于类似的预定义可接受成熟度水平。然而，该研究强调，可以通过实施建议的建议来实现 PSM 实施成熟度的未来改进。马来西亚 MHI 的 PSM 实施成熟度低于预定义的可接受成熟度水平。从整体 PSM 实施评估结果中发现，马来西亚 40% 的 MHI 显示 PSM 实施成熟度低于类似的预定义可接受成熟度水平。然而，该研究强调，可以通过实施建议的建议来实现 PSM 实施成熟度的未来改进。
