Managing human factors is a cornerstone of process safety, essential for preventing incidents that threaten personnel, the environment, and operational uptime. As Industrial Control System 〈ICS〉 cybersecurity threats escalate, applying these established human performance principles to cyber hygiene has become a critical necessity. Data suggests that the human element remains…
Process plants rely on multiple independent layers of protection to mitigate operational risks. These safeguards typically range from mechanical devices, such as pressure relief valves, to automated systems including basic process control system 〈BPCS〉 interlocks, alarms, and safety instrumented functions (SIF). While traditional safety risk assessments assume these layers function…

Cybersecurity has become a significant and credible threat to process safety. The consequences of cyber-attacks are well understood for business networks (e.g. data theft, ransomware, denial of service), but for Industrial Automation and Control Systems (IACS) there is the potential for even more severe consequences because IACS control physical systems in the real world. Case studies will be used to demonstrate how cyber-attacks on IACS can cause damage to equipment, the environment, and safety. This webinar will examine how cybersecurity is impacting process safety, considering the impact of cybersecurity events on traditional strategies for safeguarding and risk assessment, and will also introduce key steps for managing cybersecurity risk.
The selection of Mission Time, Proof Test Interval and Proof Test Coverage is very important when it comes to the PFDavg achieved by Low Demand SIFs. Oftentimes, people don’t realise the impact Mission Time can have on the PFDavg, especially when considering “Imperfect” Proof Testing. This is why it’s so important to utilize realistic Proof Test Coverage when considering the SIF. There is no such thing as “Perfect” Proof Testing, which indicates being able to find and fix all dangerous failures. These variables must be based upon End User practices and not just arbitrarily set by the SIS designers.
The purpose of this webinar is to illustrate the relationship between these variables and the impact they can have on the overall SIF PFDavg, utilizing a simple example.

Oftentimes when this comes up during class it’s clear that there’s a misunderstanding as to how these three variables can impact the PFDavg calculations. Mission Time is defined as the period of time over which a set of Safety Instrumented Function (SIF) equipment is expected to operate without major overhaul…
