One of the courses presented by ARINT SA is the Hazard and Operability (HAZOP) Study Course. The course duration is 3-days and offered in 3 different presentations.

  • 1-day theoretical course for Management,
  • 2-day theoretical course
  • 3-day theoretical course, which includes a one-day practical exercise.



Hazard and Operability (HAZOP) studies are undertaken by the application of a formal, systematic and critical examination of the

process and engineering intentions of a process design. The potential for hazard is thus assessed and malfunction of individual items of equipment and the consequences for the whole system are identified.

Authorative publications provide differing views and explanations of what a HAZOP Study is:

  • A technique to IDENTIFY potential Hazard’s and Operating problems using up-to-date information, such as the PDB (Process Design Basis), and P&ID’s.
  • A systematic, critical examination by a team of the engineering and operating intentions of a process to assess the hazard potential of mal-operation or mal-function of individual items of equipment and the consequential effects on the facility as a whole

HAZOP studies normally involve a team that has experience in the plant or design to be studied. These team members apply their experience of the design and their technical expertise in the HAZOP study sessions to achieve the aims of the HAZOP.

Each HAZOP has a set of objectives which are particular to that study and whish are decided a s near to the beginning of the study as possible.

There are a set of four overall aims to which any HAZOP should adhere:

  1. To identify all deviations (process parameters + guidewords = deviations) from the way the design is expected to work, their causes, and all the hazards and operability problems associated with these deviations.
  2. To decide whether action is required to control the hazard or the operability problem and if so, to identify the ways in which the problem can be solved
  3. To identify cases where a decision cannot be made immediately, and to decide on what information or action is required.
  4. To ensure that actions decided upon are followed.
