Functional Safety in the Process Industry

Safety in process industries with our expertise in functional safety | TÜV Rheinland

Enhanced safety in process industries with functional safety expertise

Process industries, including chemical plants, refineries or oil and gas production plants are becoming increasingly reliant upon complex safety systems to prevent harmful incidents. These electrical, electronic and programmable electronic safety-related systems (E/E/PES) are regulated by the internationally acknowledged standard IEC 61508, parts 1-7. In addition, IEC 61511 (derived from IEC 61508) defines requirements regarding the application and implementation of these safety instrumented systems (SIS) in the process industry. It describes functional safety (FS) requirements in process plants in detail via a life cycle approach, starting from the first concept, through design, installation, operation, maintenance and decommissioning. Understanding and properly applying these regulations is essential not only for compliance, but, more importantly, for protecting people, assets and the environment as well.

If you are a safety system designer, a system integrator or operator, our functional safety experts can support you when required to produce proof or evidence of functional safety within your safety integrated system (SIS). We carry out assessments, testing and provide certification services to ensure both compliance and the safe operation of your process plant.

As functional safety specialists, we provide reliable, comprehensive services to process industries worldwide. We are a one-stop-shop for all your functional safety needs and bring many years of industry experience to the table, along with high quality standards and professional objectivity.
