Pilot Study: Applicability of New QRA Guidelines for a Manufacturing Facility

Requirements

The operating environment of Singapore's industrial hub Jurong Island has grown increasingly complex, with a diverse range of chemical plants clustered together. It is imperative that safety standards are maintained at a level that is commensurate with the risks present. To achieve this vision, the Safety and Risk Management Centre (SRMC) has been set up, bringing together stakeholder agencies on a single platform to focus on safety and risk management via a Whole-of-Government approach.

JTC Corporation and the SRMC conducted pilot QRA studies to establish the applicability of the new guidelines in the local context. We were invited by JTC and SRMC to conduct a pilot study on an existing manufacturing facility in Singapore based on new guidelines and provide comparison between different guideline requirements.

Solutions

Assessments based on new QRA guidelines included the following works:

• Identified and evaluated scenarios that may pose toxic, flammable or explosive hazards, resulting in major adverse consequences;
• Assessed the risk arising from normal operations of manufacturing facility are assessed and presented the results in the form of Individual Risk (IR) contours and cumulative iso-contours;
• Recommended revisions to the guidelines with respect to the differences in results generated under existing guidelines;
• Recommended revisions to the guidelines after assessment and justification of time, resources and costs required to conduct the QRA studies based on existing guidelines.
