What is Functional Safety?

Manage outcomes with Functional Safety solutions

Every operation entails risks: risk to people, risk to the environment, and risk to equipment and facilities. Functional safety mitigates those risks by using safety instrumented systems (SIS) and other layers of protection. It’s about identifying, designing, implementing, validating, and monitoring reliable SIS and ensuring that processes fail to a safe state.

The global standard for functional safety is IEC 61511. It's a performance-based umbrella standard that informs the standards in a range of industries, including the process industries. It is intended for the users and integrators of SIS and focuses on the management of functional safety and the specification, design, installation, operation, and maintenance of SIS.

Safety instrumented systems: key to workplace safety

Safety instrumented systems implement one or more safety instrumented functions (SIFs). These functions are executed by equipment that brings the process to a safe state when a specific dangerous event occurs. Safety instrumented function equipment can include:

  • Sensors and logic solvers
  • Final elements (solenoids, actuators, valves, and motors)
  • Ancillary equipment (cables, tubing, heat tracing, etc.)
  • Interface equipment (relays, barriers, isolators, etc.)
  • Firmware and application programs
