AS IEC 61882:2017 PDF

Adopts IEC61882, Ed. 2.0 (2016), which provides guidance for use of a guide-word-driven risk identification method historically known as HAZOP. It gives guidance on the principles of HAZOP, applications of the technique and the HAZOP study procedure.

This Standard is identical with, and has been reproduced from IEC 61882:2016, Hazard and operability studies (HAZOP studies)—Application guide.

This standard describes the principles for and approach to guide word-driven risk identification. Historically this approach to risk identification has been called a hazard and operability study or HAZOP study for short. This is a structured and systematic technique for examining a defined system, with the objectives of:

• identifying risks associated with the operation and maintenance of the system. The hazards or other risk sources involved can include both those essentially relevant only to the immediate area of the system and those with a much wider sphere of influence, for example 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 risks and operability problems in a structured and systematic manner, is of great assistance in determining appropriate remedial measures.
