Reducing systematic failures

February 4, 2020

Systematic failures are the result of oversights, lapses, mistakes, and decisions of not only people, but of organizations. The UK HSE showed that most accidents involving control and safety system failures were due to incorrect and incomplete specifications, or design errors. This also includes the requirements for the application program (software implementation). If the requirements […]

Part 2: the use of Bayesian networks in functional safety

January 28, 2020

Past performance is not an indicator of future performance, especially for rare events. Past performance would not have indicated (at least not to those involved at the time) what would happen at Bhopal, Texas City, or any other accident you can think of. So, what is the definition of a safe plant? Some have responded, […]

The use of Bayesian Networks in Functional Safety

January 21, 2020

Functional safety engineers follow the ISA/IEC 61511 standard and perform calculations based on random hardware failures. These result in very low failure probabilities, which are then combined with similarly low failure probabilities for other safety layers, to show that the overall probability of an accident is extremely low (e.g., 1E-5/yr). Unfortunately, such numbers are based […]

Reducing systematic failures reduces risk

January 9, 2020

[Updated 01/21/2020 to now include download of relevant whitepaper] Functional safety engineers are immersed in performance calculations involving failure rates, diagnostic coverage, proof test intervals, common cause and much more. It’s easy for engineers to focus on math. Yet such modeling only accounts for random hardware failures. But what percentage errors shown in the well-known […]

aeSolutions gets physical with cybersecurity steps : CONTROL

December 18, 2019

John Cusimano, vice president of industrial cybersecurity at aeSolutions, was recently featured as part of Control Global’s 12 days of cybersecurity. Even though many IT technologies, such as intrusion detection, are making big strides into OT, aeSolutions’ Cusimano adds it’s important people remember that OT networks have different operational requirements, and that these tools need […]

EPA’s Risk Management Program (RMP) Reconsideration final rule

December 2, 2019

There were recently important changes made to the Environmental Protection Agency’s Risk Management Program (RMP).  On November 20, 2019, EPA Administrator Andrew Wheeler signed the Risk Management Program Reconsideration final rule to “better address potential security risks, regulatory consistency and reasonable consideration of costs.”   The EPA first proposed these changes to its RMP back in […]

Be careful when deep-frying a turkey!

November 22, 2019

Did you know?  Thanksgiving is the leading day of the year for home fires involving cooking equipment.   Thanksgiving is almost upon us. While deep-fried turkey is delicious (I’ve had it, but didn’t make it myself), please be aware of the risks. Deep-frying a turkey can be very dangerous as they have a high risk […]
