4.5.2 Safety Critical Elements The safety case must demonstrate how SCEs have been identified, list them and describe their hazard management role. The description should focus on the way in which the hazard management role of the SCE is achieved rather than the detailed way in which it is implemented.

The standards to which a SCE is designed should be identified. A list of standards that represent Good Practice in Ireland is given in section 3.4.
