Safety Instrumented Systems / Intrinsic Safety

Services for the Safety Fitness Lifecycle

Demonstrating ABB's Breadth and Depth of Their Lifecycle Offering Systems

While the IEC's 61508/61511 standards define in much greater detail the full lifecycle of a safety instrumented system (SIS), it's useful to group SIS activities in three sets of continuous activities that are not unlike an athlete's drive to improve performance through repeated cycles of assessment and planning, training and maintenance. ABB, as a pioneer in the development of safety systems for industrial applications, has service operations on all continents and dedicated safety system teams around the world to support operating companies and engineering firms through all phases of the safety system lifecycle. This figure demonstrates the breadth and depth of their offering.
