What is a safety instrumented system (SIS)?
It is an operating system designed to automatically prevent or mitigate events in industrial processes that may be hazardous. Usually, industries use SISs in high-risk situations and tasks. That is why quite often we can see chemical processing, oil and gas, power generation, or chemical businesses make use of such a safety instrumented function. To provide a safe state and deliver reliability, these systems usually consist of three components. There are sensors that detect dangerous conditions and events in the process, logic solvers for interpreting the data sensors gather, and actuators that act to prevent or mitigate hazardous conditions.
What are the benefits of SIS?
First, SIS increases safety. By preventing or mitigating dangerous situations, this set of control systems protects not only people but also property and the environment. Another important thing is that SIS is highly reliable. This translates into safe operation and much shorter downtime. There will be no unplanned shutdowns. And this is a huge advantage because it enables money-saving and productivity improvements. Today’s regulations are a key element for any plant or facility. Having a system that is compliant with such safety regulations is an important benefit to consider. Interestingly, SIS can also give more confidence to operators and plant managers because of safety and reliability improvements and make the documentation process smoother and more according to international standards.
