HAZOP Analysis

Stoppages and constellations of a system or part of a system, which is predictable may not have a negative effect over the entire life cycle – that is a principle of safety relevant systems.

With help of the HAZOP analysis as many dangers as possible can be identified beforehand. A threat in the sense of the HAZOP is a situation that poses a real or potential threat for humans or the Environment and can lead to an accident.

• Analysis of situations that can be caused by the system and situations that can affect the system from the environment.
• Analysis of possible errors e.g. control errors, development errors or errors due to mechanical wear (inadequate maintenance) and failure of electronic components

• Support in forecasting possible events, finding causes, estimating impacts, and defining countermeasures.
• classification of all possible errors: Error source: Development error / runtime error Error Type: Permanent / Sporadic / Conditional Errors Range: value / time / unsolicited actions
• Design and analysis of possible scenarios
