Implementing functional safety is critical in the process industries, which include dangerous chemical, petroleum, and petrochemical applications. The systems in these industries, down to the lowest practical level, must be designed to reduce hazards against people, property, and the environment—especially in the event of a malfunction or failure.
To explore this topic further, this paper provides you with an overview of the following:
- Safety Integrity Levels (SIL), including how to assign a level to your system.
- The standards, definitions, and characteristic values for calculating SIL.
- The various products, including fail-safe valves and redundant architectures, can help you implement functional safety easily and cost-effectively
