Safety Instrumented Systems (SIS)

Safety Instrumented Systems (SIS) are specialized control systems designed to prevent or mitigate hazardous events in industrial settings, such as chemical plants or oil refineries. They monitor processes and can automatically trigger safety measures when certain conditions are met, effectively reducing risks to people, the environment, and equipment. For example, if a system detects a dangerous rise in pressure, the SIS can shut down operations or activate safety valves to prevent an accident. Overall, SIS play a crucial role in ensuring the safe operation of complex industrial processes.
