Design Considerations for Mechanical Safety Functions

Recording Date: February 2016

Most safety functions include some mechanical components. These components can range from single devices such as pressure relief valves to more complicated subsystems such as hydraulic power units, and in some cases the entire safety function is accomplished through mechanical devices. Understanding the analysis and modeling techniques for mechanical devices is a prerequisite to designing and maintaining effective safety functions. This webinar will review common hazard analysis techniques and modelling techniques that can be applied to mechanical devices along with guidance on when to use which approach.
