When it comes to process safety, most companies will focus on the functional safety lifecycle and compliance with IEC61511. However, with the advent of the industrial internet of things (IIOT) and the growing use of wireless technologies, it is becoming more important to consider cybersecurity and the consequences of control and safety systems being compromised due to a cyber-related incident. Similarly, if there is no defined alarm philosophy and rationalization of alarms, operators can miss vital alarms and lose valuable time in being able to respond to an incident due to the volume of alarms being generated. Accidents, such as the Buncefield and Texas City explosions, highlighted the problem with operators being confused by too many alarms.
Since the standards for functional safety (IEC61511), alarm management (IEC62682) and cybersecurity (IEC62443) all follow a similar 3 phase lifecycle, it makes sense to consider all 3 together, when it comes to process safety. As such an integrated lifecycle approach will help in reducing overall operational costs via increased efficiencies.
This webinar explores the overlap between the lifecycles and how synergistic benefits can be gained by considering all 3 together.
