PAAG (HazOP) / HazID
What is the difference between HazID & HazOP?
Both HazID and HazOP are risk analysis tools used in the workplace.
The PAAg method (HazOP) is used to investigate the safety of technical equipment and is frequently used in the chemical industry. It is based on the modules of prognosis, identification of the cause, assessment of the effects and countermeasures.
In a test session, our team of experts systematically identifies all the important parts of a project using a targeted approach. The target functions define the desired functions, simple key words (yes/no, more/less, both, partially, other than) are used to change the target function and identify possible incidents.
HazID stands for hazard identification. It is more of a general risk analysis tool that draws management's attention to threats and hazards as early as possible. The classification made is based on probability and consequences. A HazID study provides a qualitative analysis of a construction site to determine the safety risk to the worker.
We are happy to carry out PAAG (HazID) or HazOP analysis with our experts. This can minimize future operational failures and hazards. This protects people, equipment and your profitability.
Checklist: PAAG process
- Failure of walls: What happens if the substance is released due to e.g. corrosion damage? How is the release of the substance detected, how is a hazard caused by the release avoided?
- uncontrolled heat supply and dissipation: How does the material behave if it becomes too hot or too cold due to overheating or unintentional cooling in a reactor?
- Failure of I&C equipment: What faults can be caused by faulty measurement technology? How does a substance or a mixture of substances behave if the pressure is too high or too low?
- Backflow of substances: Unintentional backflows can lead to undesired mixing of raw materials, auxiliary materials or operating materials. Can this unwanted mixing cause a reaction that results in the design pressure or temperature of the equipment used being exceeded?
- Incorrect operation of manual valves: Probably the most difficult point is the assessment of possible operating errors. It must be ensured that the incorrect operation of a manual valve does not lead to any safety-relevant faults in sometimes complex subsystems. If this is not the case, the system design must be modified accordingly so that incorrect operation no longer has any safety-relevant effects.
- Overfilling containers: How is it ensured that a container cannot be overfilled?
