HAZOP is an abbreviated version of hazard and operability research recognised in international practice. It is extensively used in the international practice of implementing business projects. HAZOP analysis is used to detect potential dangers and operability problems of technological and organizational objects caused by deviations from the design plan.

So, HAZOP study is the analysis of the degree of resistance of an object to artificially modelled deviations. For example- natural disasters, system failures, emergency operation, undesirable actions, the impact of degradation mechanisms, etc. It is advised to conduct this analysis at the early stages of design when the possible behaviour of the system is laid. The obtained data during the study help industry experts to ensure timely response to potential dangers and make the necessary adjustments to the project and eliminate the possibilities of residual risks in the final stage.

Main objectives of HAZOP process safety management:

  • The safety of the staff,
  • The continuity of the business projects without any interruption,
  • The stability of the characteristics of the manufactured product,
  • The development of a concept for the prevention of identified hazards,
  • Maintaining the level of productivity, etc.
Hazop Study

During hazard and operability study, a group of specialists in various scientific disciplines works under the leadership of a leader and systematically examines the relevant parts of the project or system. They identify deviations from the goals of the system design using a basic set of key control words. The whole study is focused on stimulating the imagination of participants to identify problems and health of a system. HAZOP research includes many different methods suitable for identifying potential hazards and health problems such as checklists, analysis of the types of dangers and consequences of failures. Based on the study, experts prepare final documentation for business projects.

HAZOP Working Group:

HAZOP study is carried out jointly with the participation of representatives of all interested parties who have the necessary knowledge, experience in operating and maintaining facilities. They are-

Professionals Their roles and responsibilities

? He/she explains the HAZOP process to others, guides the discussion and promotes the HAZOP analysis.

? A specialist with experience in HAZOP, but he/she doesn't get involved in the development directly

? He/she ensures strict adherence to the HAZOP study.

Registrar He/she records a discussion and draws up a visual discussion protocol. Captures recommendations or actions.
Technologist He/she is responsible for the process flow diagram.
User/Operator He/she makes recommendations on the use and efficiency of the process and the impact of deviations.
Repairer A specialist for the maintenance of the process.
Designer He/she Provides recommendations on project details or necessary information.
