Which is higher SIL 2 or SIL 3 ?

Safety Integrity Level (SIL) is a measure of the relative risk reduction provided by a safety function. It is used in industries such as manufacturing, chemical processing, and transportation to assess the reliability and performance of safety systems. SIL levels are defined based on the probability of a hazardous event occurring and the potential consequences.

SIL 2 is a moderate risk reduction level, which means that it provides a moderate level of protection against potential hazards. This level is appropriate for systems and devices with a low to moderate risk of failure or harm.

SIL 3 is a higher risk reduction level, which provides a higher level of protection against potential hazards. This level is appropriate for systems and devices with a high risk of failure or harm.

In general, SIL 3 is higher than SIL 2, as it provides more stringent requirements for the safety system. However, the specific requirements for each level may vary depending on the industry and the type of system being evaluated.
