En riskanalys börjar med att man försöker finna vilka riskerna är och vilka problem som kan uppstå. En metod man kan använda kallas HAZOP (”hazard and operability studies”).


HAZAN is short for Hazard Analysis. It is different from HAZOP where we analyse all the possible deviations using guidewords and then try to find causes for those deviations, then mitigate them via either protective measures or operating procedures. However it is also different from HAZID where only the hazards are identified.

However, complex organizations often struggle to integrate safety and operations synergically in this kind of study: dependence on traditional risk assessment schemes consumes time and resources. HAZOP as an instrument of risk analysis The HAZOP process is based on the assumption that hazards arise because design and operating elements may deviate from their original purpose. The HAZOP team discusses possible deviations and develops various scenarios in which the system or process could fail. HAZOP-type studies may also be carried out by considering applicable guide words and identifying elements to which they are applicable or by considering the parameters associated with plant elements and systematically applying guide words to them; although this last approach is not mentioned in the relevant standard, its examples of output include a study (B3) recorded in this way.

A: HAZOP requires a review of all the available Process Safety Information (PSI) as well as identification of any missing PSI necessary for an effective HAZOP analysis. This includes, but may not be limited to:

The process hazard analysis methodology selected must be appropriate to the complexity of the process and must identify, evaluate, and control the hazards involved in the process. Individuals who participate in this HAZOP and Process Hazard Analysis (PHA) Leader Certification Training Course can: Learn how to perform a PHA study from experienced professionals: collecting information, selecting the team, leading a meeting, and documenting the results HazOp analysis is undoubtedly one of the most effective hazard identification techniques in the manufacturing industry.
