MODUK DEF STAN 00-58: PART 1 PDF

SCOPE AND APPLICABILITY

This Standard is intended to be used by those who, in conforming to the requirements of Def Stan 00-56, choose to use a HAZOP Study as part of their method of hazard analysis. More generally, it is a self-contained guide to carrying out a HAZOP Study of any system. It is a detailed guide for those who need it, and a reference for experienced HAZOP practitioners.

Individual HAZOP Studies mau be carried out at various stages of a systems' life cycle.  The Standard is applicable to HAZOP Studies whenever ther are carried out. 

It is often useful for the results of a HAZOP Study to be supported by the products of other Studies, such as fault trees. Further, a HAZOP Study may be preceded and followed by other aspects of safety analysis. Such additional work P Study to is covered by Def Stan 00-56.

HAZOP Studies are concerned with both hazard identification and safe operation of equipment. However, they do not cover the ability of staff to operate a system. These training and human factors issues are addressed in Def Stan 00-56 and Def Stan 00-25.

HAZOP Studies are a team activity. Their effectiveness relies on the management of the team, the knowledge of the team members, the interaction of the individuals and thus, to a large extent, on ‘human factors' in the HAZOP process. A number of clauses in this Standard therefore address these aspects.

A HAZOP Study typically requires several HAZOP Study Meetings.
