Functional safety

Functional safety is the final preventive measure for avoiding accidents in an emergency situation. It is achieved through technical safety functions that are implemented using electrical, electronic and/or programmable electronic systems. Functional safety aims to reduce the probability of hazardous situations occurring, thereby reducing the risks to humans and the environment to a justifiable level.

Functional safety

Functional safety is the final preventive measure for avoiding accidents in an emergency situation. It is achieved through technical safety functions that are implemented using electrical, electronic and/or programmable electronic systems. Functional safety aims to reduce the probability of hazardous situations occurring, thereby reducing the risks to humans and the environment to a justifiable level.

The safety integrity level (SIL) is used to assess the reliability of safety functions.
The SIL is defined based on the risk of a hazardous situation occurring. It defines requirements for safety functions that are intended to bring the risk to an acceptable level.

IEC 61508 defines the essentials of functional safety. For many industries, the requirements have been carried over into industry-specific standards.
 

Functional safety

For example:

  • IEC 61511 – Functional safety – Safety instrumented systems for the process industry sector
  • EN 50156 – Electrical equipment for furnaces and ancillary equipment

 

These standards apply from a system’s planning and design to its operation and maintenance, extending to its dismantling and decommissioning.
