| Step 3: Identify PFEER Specified Plant Specified Plant is any of the plant of an installation which is provided To comply with Regulations a, 13, 15 and of the PFEER Regulations As a means of detecting fire and for detecting and recording accumulations of flammable gases (as required by Regulation 10 of the PFEER Regulations). — Measures to combat fire and explosion as required by Regulation 12 of the PFEER Regulations. Step 4: Prepare a record of items identified as Safety Critical Elements It is important that the record of SCEs is maintained up to date, therefore the major accident analyses and the list of SCEs should be reviewed periodically. The list should also be reviewed prior to the addition of new equipment or modification of existing plant. Atypical (but non-exhaustive) example, showing the interrelationship between MAHs and SCEs is given below. Licenced to Jeremy Goddard. Single user licence only.

The PSs are the criteria against which the initial and ongoing suitability of an SCE is assessed. Safety Integrity Level (SIL) assessments maybe used to develop PSs for instrument based protective systems. Performance Standards for SCEs are generally defined in terms of — Functionality – What is it required to do Availability – For what proportion of time will it be capable of performing Reliability – How likely is it to perform on demand Survivability – Does it have a role to perform post event Interactions – Do other systems require to be functional for it to operate Licenced to Jeremy Goddard.

This should be achieved by the following means. Identifying those assurance activities, such as maintenance, inspection and testing, that are required to maintain the SCE in a suitable condition. Ensuring that assurance activities are carried out at the appropriate time by competent people. Maintaining a record of these activities and any findings that arise. Addressing any deficiencies arising from assurance activities as soon as possible and taking any temporary measures that maybe necessary to maintain risk ALARP until deficiencies have been rectified. Any temporary measures should be subject to review and comment by the ICP. Licenced to Jeremy Goddard. Single user licence only.
