I just read a great article in the May issue of IEEE Spectrum magazine called “Managing Risk and Responsibility During a Crisis.” The author Robert N. Charette says “If the American people desire…
When it comes to IEC61511 and the selection of equipment for use within Safety Instrumented Systems (SIS) and Safety Instrumented Functions (SIF), there are only two methods that can be used to…
Increases in levels of automation and system complexity impact human error. Medical errors in hospitals and clinics result in approximately 100,000 people dying each year and cost the healthcare industry between $4B – $20B each year.…
The Greek symbol λDU is the undetectable dangerous failure rate in functional safety expressed in the unit of measurement of FITs which can be determined through FMEDAs. (FITs (λ) are failures per billion hours,…
The travel and group meeting restrictions from COVID-19 have allowed me to catch up on some reading about viruses; not the type that get transmitted to humans. This article is about the Stuxnet virus…
At exida, we just finished a Failure Modes and Effects Analysis (FMEA) on a medical ventilator. This was done for a new manufacturer who needed independent design verification. It was a fascinating job. We…
One of the commonly targeted pathways into an Industrial Automation and Control System (IACS) is through compromised remote access such as Virtual Private Networks (VPNs) and Remote Desktop Protocol (RDP). During the Stay at…
It’s hard to believe that it’s been 10 years since the Deepwater Horizon incident on April 20th 2010. Even today, the Gulf Coast is still feeling the effects. In its latest estimates, BP is looking at a…
Get your priorities (distribution) straight
A very common question is posed during alarm management training. Does the recommended alarm priority distribution of ~5% / ~15% / ~80% for high / medium / low priority alarms…
The Greek symbol λD represents dangerous failure rates in functional safety, usually expressed in the unit of measurement of FITs, and can be determined through FMEDAs. (FITs (λ) are failures per billion hours,…
Hey everybody. I hope this blog finds you, your family, and your colleagues well. At exida, we appreciate the trust you place in our solutions and services to support you in achieving your
As discussed in Part I, bow tie diagrams provide an easy-to-understand visual representation of risk management information (hazards, potential consequences, barriers, degradation factors and controls). In this article we examine the applicability of…
The Greek symbol lambda, λ, represents failure rates in functional safety, usually expressed in the unit of measurement of FITS.
λ can be expressed as a total failure rate for a device (λT), or it…
exida, the global leader in functional safety, industrial automation cybersecurity, and alarm management is thrilled to announce a new online testing platform for their CFSE (Certified Functional Safety Expert) and Read More...
