HAZOP Analysis Workflow

This workflow provides the basic, high-level steps for using this module. The steps and links in this workflow do not necessarily reference every possible procedure. For more procedures, see the links in the Related Information section.

Using the Hazards Analysis module, you can conduct the following types of Hazards Analyses:

Hazards and Operability (HAZOP) Analysis: Lets you document the known hazardous scenarios associated with a process, assess the likelihood of the risks in those scenarios occurring, and determine the best way to mitigate the risk in those scenarios.
What-If Analysis: Lets you hypothesize about the possible hazardous scenarios, determine the risk associated with them, and determine the best way to mitigate those risks.

Conducting a HAZOP analysis includes completing the following steps:

Create a Hazards Analysis, which stores the details of the HAZOP analysis that you want to perform, including the start and end dates for the analysis.
Identify the Systems/Nodes in which the hazardous scenario originates.
Define components, which includes identifying the following items:
- The system in which the hazardous scenario originates.
- The condition under which the scenario may appear.
- What causes the condition to occur.
- The risks associated with that scenario.
- The safeguards that are currently in place to mitigate the risk in that scenario.
- The probability and severity of the safety, operational (commercial), and environmental impact of the risk associated with the scenario if a safeguard is in place.
Assess the unmitigated and mitigated risks.
Link a LOPA to a Consequence.
Link Assets to each System/Node in the HAZOP Analysis.
Define the Hazards Analysis team, who will conduct the analysis.
Link the Hazards Analysis to a Reference Document, which contain reference material relevant to the analysis.

Propose a Recommendation for actions that should be taken to mitigate the risk in that scenario.
