Safety Case – Technical Scopes



10

Adopt a demonstration approach – Onus for MHI toshowcase to the Regulator

Through structured argument, supported by a body ofevidence, that provides a compelling, comprehensive andvalid case that the MHI is safe for given application in a givenoperating environment

• Argument without Evidence is Unfounded

• Evidence without Argument is Unexplained

Clear Links between prevention, control and

mitigation and the major accident hazards

Degree of analysis proportionate to

intrinsic risk

Risk reduction measures (Gaps analysed and time plans to implement the

improvements)

Safety Case -Benefits

• Systematic identify all major potential incidentsand assess their likelihood and consequences

• Improved understanding of overall hazards andrisks, enhancing ability to better manage risksarising from major accident hazards

• Priorities on where it matters

• Enhanced knowledge management and in house capability

• Better safety outcomes -> Less business disruption & costs due to poor safety standards



13

• Safety case regime not only benefits the companies,also allows regulators to come together as oneSingle Front to have better oversight and efficiencyin the management of MHIs

• Allow harmonising and streamlining of the existingrequirements of SCDF, NEA and MOM over time

• Leadership commitment and support are paramount

• Need for leaders to deepen understanding of major accidents hazards of their MHIs

• Effort and resources required to implement safety case

• Demonstrating the case to the regulators

• Implementing measures onsite throughout the lifecycle of the facility

MHI’s Commitment



15

Assess in-house Capability

• Assess what more is needed beyond your current systems - Baseline assessment based on the requirements of the Safety Case Technical Guide & Assessment Guide

• Only Consider getting external assistance (consultants) to help on what you could not do in-house

While you could engage external help on certain aspects of safety case

It is crucial to build in-house capability

Ownership of Safety Case resides with the respective MHI

Resources Required

• Engage leadership of MHIs• Operation phases of the WSH (MHI) Regulations• Explain MHD’s expectations of MHIs’ Safety Cases

Today’s MHI Symposium

• Facilitate MHI’s readiness at the start of pre-receipt

• Appointment-based 1-to-1 session with MHI

• Commencing after MHI Symposium, Oct 2016

Safety Case Clinics

Assisting MHIs with Safety Case

Safety Case implementation on-track

• Develop Safety Case Technical Guide &

Assessment Guide - Government-

Industry Joint Work Group (JWG)

• Roll out industry Safety Case capability

building programmes

• Form Major Hazards Department

• Enact WSH (Major Hazard Installations)

Regulations

• Effect Safety Case regime by 3Q 2017

• Ownership of the Safety Case resides with MHIs and therefore it is important to enhance industry’s Safety Case capabilities

• Allocation of proper resources for preparation and implementation of the Safety Case

• The resources allocated should be seen as an investment for continual and sustainable safe operation of the MHIs

Concluding Remark

Demonstrate leadership commitment

Allocate appropriate resources

Examine what is necessary for compliance

Engage MHD early
