Comparing Safety Instrumented Systems and Machine Safeguarding

By |2017-06-25T19:58:09+00:00February 2nd, 2016|Author, Edward M. Marszal, Safety Instrumented System, Services|

Industry has applied instrumentation and control devices for the purpose of safeguarding people, equipment, and business for almost as long as instrumentation and control has been used - that is machine safeguarding and safety instrumented systems. In the “wet” process industries these devices and systems have been employed to detect out of control conditions in [...]

What’s in the new version of IEC 61511? Issue 3

By |2014-11-21T14:05:10+00:00November 21st, 2014|News|

Continuing in definitions... The definition for common cause failure was greatly cleaned up... The original definition was: failure, which is the result of one or more events, causing failures of two or more separate channels in a multiple channel system. The new definition is: concurrent failures of different devices, resulting from a single event, where [...]

Moving on to the definitions... Definition 3.2.3 for basic process control systems was changed slightly.  Let's look at the change... Original: ... but which does not perform any safety instrumented functions with a claimed SIL >= 1. CDV: ... but which does not perform any SIF. Hmm.  The original states that a BPCS does not [...]

Cyber Attack Proof Safeguards

By |2014-10-07T10:29:14+00:00August 22nd, 2014|News|

There are dozens of ways to overpressure a distillation column... You can increase the heat input, drop out the cooling, flood the column with liquid, and on and on.  Yet, well designed distillation columns are almost never equipped with any safety instrumented functions that protect against overpressure, and are almost never over-pressured.  Given the ubiquitous [...]
