The document outlines the requirement for operators of hazardous systems to conduct systematic hazard analysis, specifically through HAZOP (Hazard and Operability) studies, to prevent incidents. A HAZOP study involves a team that examines non-nominal operating modes and their potential consequences, led by an independent expert known as the HAZOP leader. The document offers consulting services for HAZOP studies, including preparation, meeting facilitation, result summarization, and implementation assistance.

www.weyer-gruppe.com
In line with a concept to prevent incidents the legislative body requires operators of sys-
tems subject to statutory order on hazardous incidents to prepare a systematic analysis
of hazard sources for the systems concerned.
An established method governmentally acknowledged is the application of a HAZOP
study (Hazard and Operability), in Germany also known as the PAAG procedure.
In accordance with a specified scheme a team assumes operating modes for the exis-
ting or planned system which deviate from the nominal condition. The team also tests
how these operating modes can be developed, which consequences they could have
and which remedies are necessary, available or to be arranged.
The HAZOP leader has a special position among the team members. The HAZOP leader
chairs and coordinates the meetings, with the team working on the aforementioned
scheme for the single components.
The HAZOP leader consolidates the different points of view of various sectors of manu-
facturers and operators and ensures at the same time the compliance with the systema-
tic approach which has made the HAZOP method as successful as it is now.
The exceptional position of the HAZOP leader calls for this function to be filled by inde-
pendent experts.
Thus - as a service - we are willing to take up the position of an external HAZOP leader
performing the essential work:
À Preparation of the HAZOP study based on your planning documents
À Chair the HAZOP meetings with your team members
À Summary of the results of the meetings in an elaborated study
À Assistance of your employees with the implementation of the specified measures
