HAZOP Study

“HAZOP” study is a multi-disciplinary team oriented analytical technique that utilizes creative brainstorming to examine a process hazards and operability issue. HAZOP is a formal procedure to review design and operation of hazardous process facilities. It is used to identify deviations from normal safe operation, which could lead, to hazards or operability problems, and to define any actions necessary to deal with such deviations. The Hazard & Operability (HAZOP) process involved the following steps:

Identify a section of plant on the P&ID; referred as ‘Node’
Define the design intent and normal operation conditions of the section.
Identify a deviation from design intent or operating conditions by applying a system of guidewords.
Identify possible causes for, and consequences of, the deviation. A deviation can be considered meaningful if it has credible cause and can result in harmful consequences.
For a meaningful deviation, decide what action, if any is necessary.
Available safeguards are analyzed;
If required recommendations are made to control the hazards or operability issue;
Record results, including recommendations
