HAZOP

HAZOP is an acronym used to denote a study of hazards and operability issues. The acronym has come about by a combination of the words for HAZard and OPerability. It is one of the most popular safety and risk analysis techniques in use today across a wide range of business including, but not limited to Chemicals, Oil & Gas, Power Generation, Fertilizers, Steel & Metal foundries and many others.

First used sometime around the 60s in the United Kingdom in the Imperial Chemical Industries, it spread around the world and was quickly adopted in a large number of countries, where it became the default analysis method for judging hazards and operability issues. However the hazards part of it has received much more attention than the operations part.  It became so popular that its usage spread beyond the chemical and process industries and it also started being used for studying electrical systems (known as Electrical hazop) as well as in software functionality (known of course as software hazop). Note that in case of the version of this method used in electrical systems and software, only the possible deviations-causes-mitigations are studied, not anything from an ease of operation view.

Alongwith its expansion into non chemical industry fields (lets call it widening application areas), within the chemical and process industry itself, it became highly sophisticated (lets call it deepening scope) so that now one had multiple types of hazops, such as those used for greenfield projects, brownfield and expansion projects, a version used exclusively in commissioning, another version used in decommissioning and so on. Thus for different stages of a typical chemical plant lifecycle (which could be easily 50 years) one had different kinds of hazops. Also the increasing (and today almost exclusive) usage of computerized process control and information systems (DCS/PLC/SCADA) as well as computer based safety shutdown systems (SIS) led to the deevlopment of something that is known as CHAZOP (various referred to as Computer HAZOP or Control HAZOP). This dealt with the use of this technique to poke around these new (not now really but about 20 years back) systems that could fail in myriad ways such as displays getting blank, the terminals not responding and so on.

With the advent of a new hazard, (cyber) the C-HAZOP became more useful as a means of evaluating the effects of a cybersecurity attack on the control system or safety system. One of the best features of this technique is that it does not distinguish between bonafide causes and malafide causes, so it can be easily tailored for use in evaluating these scenarios, unlike other reliability techniques, where only bonafide failures are evaluated (such as in reliability studies). To learn about all these techniques in depth, in the comfort of your home or office and also get certified, take a look at the software below.
