Identify & Quantify Risk
Identify & Quantify Risk:
Functional Safety Engineering Perspectives from Mangan
In functional safety engineering, the ability to identify and quantity risk is a fundamental requirement. This process, which is a key component of Mangan’s functional safety engineering services, allows for the creation of effective safety systems that protect your assets and personnel from any hazards.
01 Identifying Hazard Risk
The first step is hazard identification. Identifying hazard risk involves systematic analysis of processes and systems, as well as recognizing any potential dangers that could lead to unsafe conditions. Techniques like Process Hazard Analysis (PHA) and Hazard and Operability Studies (HAZOP) can be utilized to identify risk in process-related hazards systematically. It is critical to consider every phase of the system life cycle, from design and implementation all the way to operation and decommissioning.
02 Risk Assessment - Quantify Risk
The next step is risk assessment. This involves evaluating any consequences as well as the likelihood of identified hazards. Mangan engineers utilize techniques such as Layers of Protection Analysis (LOPA) and Quantitative Risk Analysis (QRA) to quantify potential risks. They assess the severity and frequency of potential accidents, considering existing safeguards as well as the possibility of their failure.
The outcome of the risk assessment process and quantifying that risk is the assignment of Safety Integrity Levels (SILs) to each Safety Instrumented Function (SIF). SILs, as defined by the IEC 61511 standard, which indicates the required reliability of a safety function in mitigating a specific risk. The SILs range from 1 (lowest) to 4 (highest), with the higher levels denoting a greater need for risk reduction, thus quantifying the risk.
03 Risk Identification and Quantification
A critical aspect of Mangan’s methodology is the iterative nature of both risk identification and quantification. As system design further evolves or operational conditions change, the reassessment of risk is vital to make sure of the continued effectiveness of your safety measures.
Identifying and quantifying risk are important steps in Mangan’s functional safety engineering process. Through systematic analysis as well as evaluation, Mangan’s engineers make sure of the development of robust as well as reliable safety systems that effectively mitigate identified risks, thereby ensuring both the safety and reliability of your industrial processes.
