When Should You Conduct a Functional Safety Assessment (FSA)? | mangansoftware.com

Safety standards require that every Safety Instrumented System(SIS) shall have a Functional Safety Assessment (FSA) performed prior to being placed into service. A FSA is required in order to provide assurance that a SIS has been specified, designed, and tested in accordance with all phases of the Safety Lifecycle.

Why SISEngineer.com?

The world of functional safety can be a confusing place for an end-user.  Industry standards are continually changing, and they are not always clear or consistent.  There are hundreds of vendors and consultants that may or may not be able to offer good products and advice.

Meanwhile, governments and the public grow increasingly intolerant of incidents and near misses.  Traditional approaches to process safety are changing and becoming more sophisticated.

More than ever, it is critical for instrumentation and control systems engineers to have a firm understanding of the theory and practical aspects of process safety and safety instrumented systems.

The SISEngineer site offers unbiased information, tools, and training to prepare today's engineers to become technical leaders and advocates for safety.

If you enjoy this site and are interested in self-driving car safety, please checkout our sister site dedicated to automotive functional safety.
