Hazop study manual

HAZOP methodology may be found within IEC International Standard , Hazard and Operability Studies (HAZOP) Application Guide. This document presents some guiding principles in the execution of HAZOP analyses. Successful application of any risk management model requires that tools are used in concert.  · What Is a HAZOP Study? A Hazard and Operability (HAZOP) study is a qualitative technique used to identify hazards in a planned or existing process so that their associated risks to personnel or equipment can be evaluated and prevented. HAZOP studies are conducted via the use of structured and systematic examinations based on www.doorway.ruted Reading Time: 5 mins. HAZOP Tutorial Introduction A Hazard and Operability Study, commonly referred to as a HAZOP study, is a structured analysis in process design to identify potential process safety incidents that a facility is vulnerable to. A HAZOP study uses guide words to systematically determine possible failures that could result.

The HAZOP study should preferably be carried out as early in the design phase as possible - to have influence on the design. On the other hand; to carry out a HAZOP we need a rather complete design. As a compromise, the HAZOP is usually carried out as a final check when the detailed design has been completed. The HAZOP technique was initially developed to analyze chemical process systems, but has later been extended to other types of systems and also to complex operations and to so˝ware systems. A HAZOP is a qualitative technique based on guide-words and is carried out by a multi-disciplinary team (HAZOP team) during a set of meetings. The overall procedural steps in a HAZOP study are: Step 1: The Company’s Safety Team Meet. Step 2: Identification of the Project for the HAZOP Study. Step 3: Identification of the Lead Process Engineer. Step 4: Selection of an Independent HAZOP Team Leader. Step 5: Defining the Purpose and Scope of the HAZOP Study.

1 Overview. Hazard and Operability Analysis (HAZOP) is a structured and systematic technique for system examination and risk management. 30 gush the tools that are used to systematically direct the HAZOP Study. The basic guide words are: NO, MORE, LESS, AS WELL AS, PART OF. Operability Studies (HAZOPs) and then restate the basic principles of HAZOP in order to show how the established Guide Word driven method can be used for HF.
