Safety Case essentially is a case, which makes a statement based on evidence through argument.
Safety case, under Singapore’s WSH(MHI) regulations, is also a regulatory tool. MHI is required to develop its safety case, and demonstrate it to the MHD and convince them that the strategy for managing safety is satisfactory, through the adoption of ALARP principle.
A set of documents
It also can be viewed as a set of documents, which demonstrate that the MHI are designed, constructed, commissioned, operated and decommissioned in such a way that the risks to personnel, the public and the environment are minimized, for the use of both regulators and operators.
In Singapore, this set of documents should cover at least:
- Hazard identification process
- Identification of hazards with the potential to cause major accidents
- Evaluation of major accident risks
- System/procedures put in place to control them
- Measures to limit major accident consequences
- ALARP methodology
Core Feature of WSH(MHI) Regulation:
Safety Case Regime is the core feature of the WSH(MHI) Regulations. It allows flexibility for MHIs to tailor their risk mitigating measures, enabling MHIs to address their risk in a more holistic manner.
Under the Safety Case Regime, MHIs are expected to:
- Take on greater responsibilities.
- Proactively identify and manage Safety Health and Environment (SHE) risks through integration of all SHE protocols.
- Demonstrate to regulators that their risks are as low as reasonably practicable.
A paradigm shift of Singapore’s MHI regulation
Safety Case Regime is a paradigm shift of Singapore’s MHI regulation, from prescriptive regulation to goal setting regulation.
In the past, the regulator is responsible to identify and maintain an appropriate set of regulations for operators to adhere to. While in safety case regime, the operator will be responsible to identify and implement appropriate measures, and the regulator will review and assess operator’s safety case.
