In the ALARP region, principles of continual improvement apply. This means that risk reduction
measures should be adopted until the point where hazards of operating the difficulty and cost of
adoption exceeds their benefit.
Furthermore, where the risk level is close to the tolerability/acceptance criteria, control measures
should be adopted unless their difficulty and cost grossly outweighed their benefit. Other than in
exceptional circumstances, it would be expected that all control measures set out in industry
standards are adopted. The FSA must detail the risk acceptance criteria chosen, the rationale for
selection and how the criteria would to be used.
4.4.4 Safety Critical Elements (SCEs)
In demonstrating that the risks associated with the identified MAHs have been reduced to ALARP
levels, it is essential that facility owners clearly identify the Safety Critical Elements (SCEs)
associated with each MAH.
In the context of these Guidelines, SCEs are parts of the facility, including physical equipment as
well as software, which are designed to prevent or limit the effects of a major accident, or the
failure of which will result in a major accident. Essentially, a Safety Case should identify SCEs that
will help mitigate the consequences of MAHs as outlined in section 4.4.1 of these Guidelines. The
matrix of MAHs and associated SCEs must be accompanied with the required performance
standards for the SCEs, so as to assure the Safety Case proponent, as well as the DPR, that all
identified SCEs will continue to perform as designed, whenever called upon do to so. The
Department’s validation and verification exercises, as captured in section 5.4 of these Guidelines,
will involve ascertaining that SCEs identified in the Safety Case are in place, well maintained and
functional.

Safety Management Systems
Safety Management System (SMS) is the section in which an Operator/Facility owner describes
the safety policy of the company, references and integrates or shows the integration of all safe
and operating procedures, roles, responsibilities and demonstrates how all risks associated with
