What is SIL?

What is SIL? Should we select SIL 4 for our Safety Instrumented Function?

Jenny is a young engineer assigned to a project to install a new Safety Instrumented System for a plant. Eddie is her supervisor, who is in charge of the project. Jenny wonders why have different SILs for different SIFs. Eddie explains the reasons. Watch the video below to know more. What is SIL? Safety Integrity Level (SIL) is a measure used to describe the integrity of a Safety Instrumented …

Safety Instrumented Systems- Design

Many process plants handle large amounts of hazardous materials (including flammable, explosive or toxic chemicals)  at high temperatures and pressures (or in vacuum conditions)via complex processes. Hence there is a risk that there could be a disaster if something goes wrong and we could have fires, explosions and toxic chemical releases that can harm people and the environment. These incidents also damage assets and cause large scale destruction. In …

Safety Instrumented Systems- a Life-cycle approach works best

What are Safety Instrumented Systems? Safety Instrumented Systems are automation systems that kick into action when some deviation from the normal operating parameters has the potential to trigger an unwanted incident. These include both (relatively) simple systems like OPS (overfill prevention systems), that prevent overfilling a storage tank by sensing the high level and automatically stopping the inlet flow on high level, as well as more complex systems such …

What is the Safety Life Cycle? | Functional Safety IEC 61511

The Safety Life Cycle The Safety Life cycle is an important concept in the domain of Functional Safety. It recognizes the fact that “Safety” is not a one shot affair, or something like a standard product or service that can be obtained by a one time payment or effort. Rather Safety (including Functional Safety, Process Safety, Occupational Safety and all other branches of Industrial Safety) are a process and …

What is a Safety Instrumented System?

A Safety Instrumented System (SIS for short)  is used in many process plants to ensure continued safe operation of the process. In case of any disturbance that is likely to result in an unwanted incident the SIS automatically brings the process to a safe state and prevents loss of life, asset damage and environmental damage. For process plants that handle hazardous, toxic, explosive or other similar materials, Safety Instrumented …
