The HAZOP study is conducted to examine the overall process design, searching for operating deviations and process interactions that can lead to hazardous situations or operability problems, which include:

  • Review of the design and operation of process facility
  • Damage to equipment/asset/environment
  • Operability/maintainability problems
  • Plant non-availability/limitation and lack of product quality
  • To identify all possible causes of deviations from normal operation that could lead to any safety hazard, environmental risk or operability problem
  • Identification of hazards, possible causes and consequences and suggest recommendations for necessary changes/ alterations
  • Critical examination of the process and the engineering intentions to assess the hazard potential or mal-operation or mal- function of individual items of equipment and the consequential effects on the facility as a whole.

Objective of the HAZOP Study

The objectives of the HAZOP study is to:

  • Check the design and consider whether any of the deviations, which may occur, either from a malfunction or mal-operation, may cause a hazard to people working on the installation or to the plant.
  • It accommodates the status of recognized design standards and codes of practice but rightly questions the relevance of these in specific circumstances where hazards may remain undetected.
  • Check whether the precautions incorporated in the design are sufficient to either prevent the hazard occurring or reduce any consequence to an acceptable level.
  • Ensure that the process can be functionalized and maintained safely.
