SAFETY CASE ASSESSMENT
INITIAL REVIEW – Production or Non Production Installation Safety Case
Work Instructions
The purpose of initial review is to determine:
1. If the essential components that SCR 2015 Schedules 6 / 7 are present in the submitted safety case;
2. If the submitted case is adequate to give it a good prospect of acceptance in the subsequent
assessment process.
The initial review is not a consideration of the quality and detailed justifications made-out in the case, this is
undertaken later in topic specialists’ individual assessments.
IMT Focal Point Inspectors should use this template to record the initial review of a safety case against the
requirements of SCR 2015 Schedules 6 / 7. When complete, it should accompany the Assessment
Instructions sent to topic specialists.
Duty holders should be encouraged to complete the table column labelled “Safety Case Reference” and
include appropriate comments to identify the section where the relevant information is to be found within the
Safety Case. This will assist Inspectors to quickly locate relevant information, thus making the assessment
process more efficient, which is a mutual benefit.
For a new case – the initial review should determine if the information required by Schedules 6 / 7 of the
regulations is present and where it appears in the case (e.g. chapter or section).
For a material change – the initial review should identify which sections of the case have been revised and
therefore require assessment. For ‘Material Change’ submissions the duty holder must still submit a full
copy of the safety case showing clearly where the proposed revisions are incorporated (Regulation
24(2)).
The Initial Review Template complements the guidance to the regulations and topic-specific guidance,
standards and good practice. Together with topic-specific templates, it forms part of the complete record of
the assessment process undertaken by the Competent Authority.
Relevant Guidance

APOSC Principles:
Factual information


Principle 1
The factual information should meet the [SCR15] requirements and provide sufficient detail to
support the arguments made in the case
GASCET Chapters:
1-4 Assessment of Adequacy

In assessing the major accident hazard aspects of safety case submissions it is necessary to
determine the adequacy of, inter alia:




Hazard identification
Risk evaluation
Risk management measures [barriers and performance standards]
The demonstration of compliance with relevant statutory provisions.…
