The purpose of this course is to describe the principles and procedures of
Hazard and Operability (HAZOP) Studies. HAZOP is a structured and systematic
technique for examining a defined system, with the objective of:
Identifying potential hazards in the system. The hazards involved may include
both those essentially relevant only to the immediate area of the system and
those with a much wider sphere of influence, e.g. some environmental hazards;
Identifying potential operability problems with the system and in particular
identifying causes of operational disturbances and production deviations likely
to lead to nonconforming products.
An important benefit of HAZOP studies is that the resulting knowledge, obtained
by identifying potential hazards and operability problems in a structured and
systematic manner, is of great assistance in determining appropriate remedial
measures. The course is designed using the tools and techniques identified by
IEC 61882:2016.

LEARNING OUTCOMES
By the end of this course you will understand how to:
* prepare for a HAZOP study meeting and programme – including defining the
scope of the study and choosing the team
* choose nodes (parts of the drawings or operation for HAZOP study)
* estimate the programme requirements for the successful completion of a study
* use facilitation techniques to motivate the team and keep them on task
* avoid common problems encountered during study meetings, including
challenging behaviours
* formulate the HAZOP study report
* fulfil the team leader’s role in implementing recommendations and managing
the process
--------------------------------------------------------------------------------

* Anyone with experience of the HAZOP technique who is required to lead HAZOP
studies
* Process safety engineers, loss prevention specialists, production engineers,
process design engineers, project engineers, process programmers and
