When: At least 6 months before you submit the safety case.
The purpose of the pre-receipt meeting is to seek alignment on the key principles and approaches used by your MHI in the development of your safety case.
You need to have the following items prepared for discussion at the pre-receipt meeting:
- Descriptive information of the MHI.
- Predictive aspects – Methodology and the selection of:
- Major Accident Scenarios (MAS)
- Representative set of MAS
- Safety Critical Events (SCE)
- ALARP methodology and ALARP demonstration of one SCE.
Conclusions of the meeting will be documented in a pre-receipt summary, which will be emailed to you.
Processing time: About 6 months.
May take longer if there are delays in responding to MHD’s clarifications or unresolved safety case issues.
To submit safety case:
- Email 1 softcopy of your safety case to:
- Post 1 hard copy of your safety case to:
Major Hazards Department
Occupational Safety and Health Division
MOM Services Centre
1500 Bendemeer Road
- MHD will assess your safety case and seek clarifications, if required. On-site verification will be conducted to verify the implementation of the measures described in the safety case.
- When assessment is completed, you will receive:
- Conclusions of the safety case assessment.
- Proposed Intervention Priorities (PIP) – Broad master plan capturing all planned interventions over the next 5 years based on the conclusions of safety case assessment.
- Intervention Plan (IP) – Typically covers 2 years and will be reviewed by MHD every 1-2 years.
- The IP is aligned with PIP and includes:
- All planned interventions
- Issues of non-compliance
- Findings from safety case assessment
- Ongoing investigation work
- Follow-up on all the action items in the PIP and IP.
- Ensure that the control measures described in the safety case are properly implemented, and that relevant documents are available for verification.
MHD will inspect your MHI to check on implementation progress according to the PIP and IP.
To ensure that your safety case remains updated and relevant to your operations, you need to review, and if necessary, revise your safety case:
- Every 5 years.
- When there is new knowledge or modifications at your workplace.
The review should include:
- Details on the changes that have occurred.
- Assessment of the significance of the changes on the identification, prevention, control and mitigation of major accidents.
- Cumulative effects of minor changes that have taken place.
For review every 5 years
- Update your safety case by consolidating all outstanding and actioned items into the safety case.
- Inform MHD of revision details using the safety case revision form.
Before making significant changes
E.g. plant modifications or changing the quantities of dangerous substances.
- Consult MHD to determine if you need to conduct a Quantitative Risk Assessment (QRA).
- Notify MHD upon confirmation of your modifications and planned commissioning date.
- Review and revise safety case.
- Submit the revised safety case to MHD for assessment.
