Project Description
HAZOP & HAZID
UNDERSTANDING HAZOP & HAZID
HAZOP study is to carefully review a process or operation in a systematic manner to determine whether deviations from the design or operational intent can lead to undesirable consequences. This technique can be used for continuous or batch processes and can be adopted to evaluate written procedures. The HAZOP team lists potential causes and consequences of the deviation as well as existing safeguards protecting against the deviation. When the team determines that inadequate safeguards exist for a credible deviation, it usually recommends the action be taken to reduce the risk.
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 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 obtain a list of questions to put to a supplier
To improve the safety of existing facilities
Objective of carrying out a HAZID 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.
Process Hazard Analysis (PHA) is a thorough, orderly, and systematic approach for identifying, evaluating, and controlling the hazards of processes. The process hazard analysis methodology selected must be appropriate to the complexity of the process and must identify, evaluate, and control the hazards involved in the process. The process hazard analysis shall address the following:
The hazards of the process
The identification of any previous incident that had a likely potential for catastrophic consequences
Engineering and administrative controls applicable to the hazards and their interrelationships
Consequences of failure of engineering and administrative controls
Stationary source siting
A qualitative evaluation of a range of the possible safety and health effects of failure of controls.
In addition to the Chairman and scribe, the HAZOP & HAZID team comprises of the following personnel
Design consultant / Project Manager
Production Manager
Chemical engineer / Chemist
Maintenance Manager
Electrical Engineer
Instrument Engineer
