Why is data quality important in the LOPA process?

Accurate data is essential in the Layer of Protection Analysis (LOPA) process because it directly influences the validity of risk assessments. The foundation of LOPA relies on quantitative data to evaluate the likelihood of hazardous events and the effectiveness of existing safeguards. High-quality data allows practitioners to identify potential risks accurately, estimate the frequency of those risks, and evaluate the reliability of protective layers.

When the data used is precise, it leads to more reliable calculations of risk tolerance and helps in making informed decisions regarding additional layers of protection that may be necessary to mitigate those risks. Conversely, poor-quality data can result in flawed analysis, potentially leading to inadequate risk management strategies that could compromise safety and operational integrity.
