Hazard and operability (HAZOP) studies were introduced to the chemical industry by ICI Ltd as a method by which plants could be assessed to determine the potential hazards they present to operators and the general public. HAZOP is defined by the British Chemical Industry Safety Council as: ‘The application of a formal systematic critical examination of the process and engineering intentions of the new facilities to assess the hazard potential of mal-operation of individual items of equipment and the consequential effects on the facility as a whole.’ HAZOP is defined in AIChE Guidelines for Hazard Evaluation Procedures as: ‘A systematic method in which process hazards and potential operating problems are identified using a series of guidewords to investigate process deviations.’

Hazard and operability (HAZOP) studies were introduced to the chemical industry by ICI Ltd as a method by which plants could be assessed to determine the potential hazards they present to operators and the general public.

HAZOP is defined by the British Chemical Industry Safety Council as:

‘The application of a formal systematic critical examination of the process and engineering intentions of the new facilities to assess the hazard potential of mal-operation of individual items of equipment and the consequential effects on the facility as a whole.’

HAZOP is defined in AIChE Guidelines for Hazard Evaluation Procedures as:

‘A systematic method in which process hazards and potential operating problems are identified using a series of guidewords to investigate process deviations.’

The definition applied during this HAZOP is as follows:

‘HAZOP is a qualitative risk assessment technique, utilising the expertise of a multidisciplined team, to systematically identify and evaluate potential hazards and operability problems of a process, system or procedure resulting from consequences of deviations from the design intent for all operating modes.’

This definition also states the objective of a HAZOP study, which is to identify all hazards and operability problems of new and modified processes, systems and procedures.

Each HAZOP has a set of objectives particular to that study which should be determined and communicated to the team, prior to the start of the study. A HAZOP study should address the following four overall aims:

1. To identify the causes of all deviations from the design intent.

2. To determine all hazards and operability problems associated with these deviations,

3. To decide whether action is required to control the hazard or operability problem,

4. To ensure actions decided upon are implemented.

The HAZOP study is primarily a hazard identification tool. When HAZOP is applied to operational facilities the team may evaluate pragmatic operational measures to safely manage non-optimal design constraints or propose design modification required to remove bottlenecks.
