Hazard and Operability Analysis (HAZOP) is a structured and systematic technique for system examination and risk management In particular HAZOP is often used as a technique for identifying potential hazards in a system and identifying operability problems likely to lead to nonconforming products
HAZOP FUNDAMENTALS - DESIGN INTENT PARAMETERS GUIDEWORDS AND DEVIATIONS Introduction The hazard and operability (HAZOP) study is the most commonly used process hazard analysis (PHA) method in the world today It is one of the techniques commonly accepted by regulators

The HAZOP concept is to review the plant in a series of meetings during which a multidisciplinary team methodically "brainstorms" the plant design following the structure provided by the guide words and the team leader's experience The primary advantage of this brainstorming is that it stimulates creativity and generates ideas
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 software 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
HAZOP Studies Identifies Hazards Systematically (based on malfunctions) Does not address Risk (probability can be high or very low) Addresses Consequences (harmless or harmful) Proposes Actions (Design and/or Operational) Based on analyzing one equipment at a time
Training Guide: Hazard & Operability Analysis (HAZOP) Page 3 of 9 2 HAZOP Methodology1 The HAZOP analysis process is executed in four phases as illustrated below: • 2 1 Definition Phase The Definition Phase typically begins with preliminary identification of risk assessment team members HAZOP is intended to be a cross-functional team effort
In a conventional process HAZOP (if I may call it that) we are usually workingfrom a design represented in P&IDs backed up by equipment datasheets instrumentationcause and effect diagrams layouts chemical data etc – and the intention usually describesprocess conditions such as ?ows temperatures pressures levels and the like
Principles of HAZOP A study is a detailed hazard and operability problem identification process carried out by a team HAZOP deals with the identification of potential deviations from the design intent examination of their possible causes and assessment of their consequences Key features of HAZOP examination include the following
HAZOP Methodology The Hazard and Operability Study or HAZOP is a detailed systematic study of the process design and outline operating and maintenance procedures to identify the consequences of deviation from design intent It may also be applied to other activities or procedures to analyze deviations from design ICI Hazard Studies

What is HAZOP based on?
- In particular, HAZOP is often used as a technique for identifying potential hazards in a system and identifying operability problems likely to lead to nonconforming products. HAZOP is based on a theory that assumes risk events are caused by deviations from Definition: SYSTEM is the design or operating intentions.
What is hazard and operability analysis (hazop)?
- Hazard and Operability Analysis (HAZOP) is a structured and systematic technique for system examination and risk management. In particular, HAZOP is often used as a technique for identifying potential hazards in a system and identifying operability problems likely to lead to nonconforming products.
What is ahazop study?

What is the HAZOP examination phase?
- Once the HAZOP guide words are selected, the Examination Phase may begin. The Examination Phase begins with identification of all elements (parts or steps) of the system or process to be examined. For example: Physical systems may be broken down into smaller parts as necessary
