At BakerRisk, we combine a thorough understanding of how hazards develop with a practical approach to resolving risk with Safety Instrumented Systems (SIS). Using the Safety Integrity Level (SIL) target determination methodology as your policy requires, we support you with SIL verification calculations to confirm the SIL target is achieved and support the development of written specifications and procedures to ensure safety lifecycle compliance.
SIS/SIL Solutions
Safety Instrumented Functions are intended to protect against specific and identifiable hazards such as fires, explosions, toxic releases, or financial losses. BakerRisk offers support for all safety lifecycle phases based on your needs. Our world-class process safety software aids you in providing the right resources for a given hazard, and if your site has not already developed a program for safety instrumented systems, we support the creation of an integrated SIS program using industry best practices. The SIS/SIL services we offer include:
Safety and Risk Mitigation
The process industry requires numerous protective systems to prevent incidents like fire, explosion, or toxic releases that can cause fatalities and/or monetary losses. As such, SIS have been used for many years to reduce risk in the process industries. If instrumentation is to be effectively used for Safety Instrument Functions (SIF), it is essential that this instrumentation achieves a certain minimum set of standards and performance levels.
We have over 40 years of experience understanding the hazards, working with the instrumentation, and sitting on the committees maintaining the standards. As such, our risk management experts are qualified and ready to provide you with the tools and solutions you need.
The Standards IEC 61508 and IEC-61511 introduced requirements that have shaped the design, selection, installation, operation, and maintenance of instrumented safety systems. These standards are based on a SIS Safety Lifecycle and are designed to address SIS management from the initial concept through decommissioning. The standards require that a performance target be assigned and verified for each SIF and that this target is quantitative and measurable — generally known as the Safety Integrity Level (SIL).

Today’s process safety practices are invariably the result of hard lessons learned by industry from major accidents. Process safety management systems are generally credited with reducing major accident risk in process industry operations. The prevention and mitigation of major accidents relies upon appropriate layers of protection or barriers working on demand.
Standards such as IEC 61511 (Functional Safety for Safety Instrumented Systems for the Process Industry Sector) are derived off of the concept that Safety Instrumented Systems (SIS) should be designed, installed, operated and maintained as part of a holistic safety lifecycle. Yet, what is often forgotten is that IEC 61511 offers a value proposition that, if embraced, can reduce long-term cost over the lifetime of the equipment.
