Which of the following aspects is evaluated when selecting SIL values?

When selecting Safety Integrity Levels (SIL) for a system, it is critical to evaluate both the severity of potential accidents and the occurrence rates. This evaluation ensures that the safety measures implemented are proportionate to the risks associated with a given process. The severity of potential accidents indicates the potential impact on human safety and the environment if a failure were to occur. By understanding the consequences, organizations can prioritize which risks need more robust safety measures. Simultaneously, occurrence rates provide insight into how often these accidents could potentially happen. A high-frequency event might require a more stringent safety protocol compared to a low-frequency event, even if both have similar severities. Thus, the combination of these two factors—severity and occurrence rates—plays a crucial role in determining the appropriate SIL for a system, ensuring adequate safety measures are in place to mitigate risks effectively.
