Blog Entry: Why should I use an Alarm Deadband?
As many of you will know, one of the most common form of nuisance to operators working industrial controls are repeating or chattering alarms. On a typical plant, repeating alarms may account for around 50% of the alarm annunciations. They are a problem because the operator will have to silence…

Recorded Webinars: How is Cybersecurity Changing Process Safety?
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 look at how cybersecurity is impacting process safety, considering the impact of cybersecurity events on traditional strategies for safeguarding and risk assessment, as well as introduce key steps for managing cybersecurity risk.

Recorded Webinars: How a Bad PHA/LOPA Can Damage the Design of your Safety System
Hazard and Operability Study (HAZOP) is one of the most popular methodologies for Process Hazard Analysis (PHA). Layer of protection analysis (LOPA) is a methodology to further quantify the risk following up on the PHA.
These two exercises pave the foundation for the design of the Safety Instrumented System (SIS). We will first look at the basic ideas about PHA and LOPA and look at the causes for the problems. Finally we will move on to a few consequences and the impacts of a bad HAZOP and LOPA on the SIS.
News Item: New White Paper: When and When Not to Use Failure Rates Based on Cycle Testing Data
Based on Siemens Simatic PCS7 System Any industry that has a requirement for a heated medium, whether it is used for process, utilities or emissions, utilizes equipment that has combustion controls and combustion safeguards. There has been an evolution in these controls from a traditional control that separates the DCS…
Blog Entry: How the PHA and LOPA are going to affect your SIS
Both Process Safety Analysis (PHA) and Layer of Protection Analysis (LOPA) occur in the early stage of the Functional Safety Lifecycle, detailed in both IEC 61511 and IEC 61508. They both serve significant roles in the whole process safety management. Yet, as a facilitator for both PHA, LOPA and Alarm…
Recorded Webinars: Alarm System Auditing and Enforcement – The Why and the How
One of the important tasks defined in the ISA-18.2 / IEC 62682 alarm management lifecycle is to audit the alarm configuration settings in the control system (actual) versus those that have been specified during rationalization and are documented in the master alarm database (target). This webinar will discuss the Auditing and Enforcement process including why it should be done and how it can complement (but not make up for) the MOC process. We will discuss what alarm parameters are most important to audit and why. We will also review the pro’s and con’s of different methods for auditing and for enforcement.
News Item: New White Paper Describes exida’s Most Detailed Field Failure Study to Date
exida has just released a new White Paper describing their most detailed field failure study to date. A comparison between exida’s Calibrated FMEDA process and OREDA failure reports has been performed on a specific manufacturer/model number valve. The comparison was accomplished with unprecedented access to unpublished failure reports from the…
Blog Entry: Alarm System Auditing and Enforcement – The Why and the How
One of the more important tasks in the alarm management lifecycle is auditing of the alarm system configuration. Auditing preserves your investment in rationalization, checks for changes that bypassed the MOC process, and helps you to maintain the integrity of the alarm system. Oh, and it also required per the…
