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
in Quality Risk Management HAZOP is also commonly used in risk assessments for industrial and environmental health and safety applications Additional details on the HAZOP methodology may be found within IEC International Standard 61882 Hazard and Operability Studies (HAZOP) Application Guide
PRIMATECH WHITE PAPER 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
A Hazard and Operability (HAZOP) study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment or prevent e?cient operation The HAZOP technique was initially developed to analyze
A HAZOP study identifies hazards and operability problems The concept involves investigating how the plant might deviate from the design intent If in the process of identifying problems during a HAZOP study a solution becomes apparent it is recorded as part of the HAZOP result; however care must be taken to avoid trying to find solutions
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 issues We shall also consider the appropriate way to consider HF at other stages of the project within other Hazard Studies
HAZOP is a well recognized method of identifying hazards & problem which may prevent an efficient operation & lead to a hazard HAZOP is a technique to critically examine a system part by part in a very systematic manner to find out the cause and consequence of every conceivable deviations
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
· HAZOP is a systematic reasonably comprehensive andflexible · It is suitable mainly for team use whereby it is possible to incorporate the general experience available · It gives good identification of cause and excellent identification of critical deviations
3 1 Description of the HAZOP method According to the standard IEC 618821HAZOP is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment or prevent efficient operation
• Hazard Analyses using Hazard and Operability (HazOp) analysis method and System Theoretic Process Analysis (STPA) method • Safety requirements Research gaps in functional safety approaches for application to safety-critical electronic control systems including highly automated vehicles
