How does OSHA decide that a particular clause of an industry practice or even a particular practice applies to a covered or non-covered facility?
Process Automation Reliability versus Safety
Is It Possible to Have Safe Systems That Aren’t Considered Reliable?
So how does this statement relate to the process industries? Reliability and safety are many times treated differently, as if they’re dissimilar concepts or philosophies. It seems certain that we want a reliable and safe plant, but how do these concepts interact in a process plant?. Read full paper
SIS Management – Part 2: Maintenance and Repair
You are about to design your plant’s first Safety Instrumented System (SIS). So, what is some of the initial information that you need before you can efficiently start? No doubt you have the hazard and risk analysis document which describes the necessary safety instrumented function and other safety controls, alarms and interlocks (SCAI) used to protect against the same hazard. P&IDs which show the location of the proposed sensors and final elements? Certainly!
For our second industry incident case study focusing on safe automation management system practices and inherently safer automation practices, we have a summary of another explosion event. This incident occurred at a facility located near Hemel Hempstead, England, December 11, 2005, and resulted in 43 injuries and substantial economic loss. Key safe automation management practices highlighted in this case study include Maintenance and Repair and Management of Change, compounded with other safe automation implementation deficiencies.
