A hazard and operability study (HAZOP) is a structured and systematic examination of a complex planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment.

The technique is based on breaking the overall complex design of the process into a number of simpler sections called 'nodes' which are then individually reviewed. It is carried out by a suitably experienced multi-disciplinary team (HAZOP team) during a series of meetings.

The HAZOP technique is qualitative, and aims to stimulate the imagination of participants to identify potential hazards and operability problems. Structure and direction are given to the review process by applying standardised guide-word prompts to the review of each node.

Objective of carrying out a HAZOP study:

To check a design

To decide whether and where to build

To decide whether to buy a piece of equipment

To decide whether to buy a piece of equipment

To check running instructions

To improve the safety of existing facilities

HAZID:

HAZID (Hazard Identification) is a qualitative technique for the early identification of potential hazards and threats effecting people, the environment, assets or reputation. The major benefit of a HAZID study is to provide essential input to project development decisions.It is a means of identifying and describing HSE hazards and threats at the earliest practicable stage of a development or venture.

Objective of the study:

To identify the potential hazards and to reduce the probability and consequences of an incident in site that would have a detrimental impact to the personnel plant, properties and environment.
