Energy Institute Guidelines for the management of safety critical elements 2007
4.2 MAJOR ACCIDENTS
Major accidents are fires, explosions or releases of dangerous substances that will cause death or serious injury major damage to the structure or plant or loss of stability the collision of a helicopter failure of life support systems for diving operations or any other event involving death or serious injury to five or more people.
4.3 PERFORMANCE STANDARDS
A Performance Standard is a qualitative or quantitative statement of the performance required of a system or item of equipment in order for it to satisfactorily fulfil its purpose.
It is a requirement that Performance Standards should be established for all SCEs.
4.4 VERIFICATION SCHEMES
Verification schemes are written schemes implemented to confirm, or otherwise, that SCEs are suitable and remain in good repair and condition. As from April verification schemes should also cover specified plant required by PFEER and previously subject to
PFEER written schemes of examination.
4.5 INDEPENDENT COMPETENT PERSONS
Independent Competent Persons (ICPs) are required to carryout various functions under the verification scheme to ensure that the process of managing risks associated with the Major Accident Hazards is working effectively. It is a requirement that ICPs must be sufficiently independent so as to be impartial and objective in their judgement such that safety is not compromised. The role of the ICP can either be undertaken by a single organisation or by a number of different individuals or organisations considering separate aspects of the installation. In the latter case however, greater coordination will be required by the duty holder to ensure that all parts of the scheme have been adequately addressed and that interfaces are effectively managed. Although not mandatory, it is generally recommended that where multiple ICPs are employed, one has an overseeing role.
