HAZOP guide words are key supporting elements in the execution of a HAZOP analysis. According to IEC Standard 61882: The identification of deviations from the design intent is achieved by a questioning process using predetermined “guide words”.

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 method identifies deviations from design intent by applying guide words, such as No, More and Less, to aspects of the design intent (such

Guidewords are the tools that are used to systematically direct the HAZOP Study. They are words or phrases that, when considered together with a parameter, form a hypothetical deviation for the Team to consider. The basic guide words are: NO, MORE, LESS, AS WELL AS, PART OF, REVERSE and OTHER THAN.

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. Identify all deviations from the way a system is intended to function: their causes, and all the hazards and operability problems associated with these deviations.

A HAZOP study is a simple and well-structured methodology for hazard identification in process plants. It is an investigation technique that is designed to inspire imaginative thinking (or brainstorming) by a team of experts to identify hazards and operational problems while examining a process or system thoroughly and systematically.

These guide words help structure the analysis by prompting the team to think of possible deviations. Common guide words include: No: A complete absence of a parameter (e.g., no flow, no reaction). More: Higher-than-normal levels of a …

Stress testing is achieved by asking questions based on a set of guidewords. Each guideword is a combination of words that describe a critical property or parameter of the system and how it might deviate from normal or expected behaviour.
