Blog Entry: Nothing Happens Until Someone Sells Something!
When I first heard this phrase, I was working in an R&D group developing electronic DCS. My first interpretation was that until the Sales Department got an order for a new product, new ideas sort of sat on the shelf with low priority… meaning that people were probably working on…

Recorded Webinars: Random and Systematic failures – Issues and Solutions
Functional safety standards provide definitions of two different categories of failures: random failures and systematic failures. These were created during the standards committee discussions of failure types to be modeled in the probabilistic failure analysis. The committee thinking was that systematic failures could be permanently “fixed” by a change in a design or a procedure.
Many companies establish programs to record and analyze failures. A failure rate analysis is performed to determine device failure rates. One problem observed while reviewing these studies is that many people have completely different interpretations of the definitions of random versus systematic failures.
At some sites, those performing the analysis have realized that failures classified as systematic do prevent safety devices from performing their safety function and are therefore dangerous.
This webinar will go over a recent survey performed and also discuss different viewpoints on how to classify failures.

Blog Entry: The Crossroads of Alarm Management and Process Safety
Recently I was reading The Manufacturing Operations Technology Viewpoints blog and came across an interest post on Alarm Management that cites exida’s Alarm Management cheat sheet. The blog post entitled The Crossroads of Alarm Management and Process Safety is a great summary for any one who needs a primer on…
Service: Process Hazard Analysis (PHA) Facilitation
The main objective of a Process Hazards Analysis (PHA) is to identify potential hazards posed by the process and associated equipment. The PHA is the first step in the functional safety lifecycle. This first step is critical, as adequate risk reduction measures cannot be implemented for hazards that are not…

Service: HAZOP Facilitation
HAZOP stands for Hazard and Operability study. HAZOP is a process hazards analysis procedure originally developed by ICI in the 1970s. The method is highly structured and divides the process into different operationally-based nodes and investigates the behavior of the different parts of each node based on an array of…
