This guide provides a basis for NBIC Inspectors use in reviewing Pressure Relief Devices (PRD’s) for compliance with the National Board Inspection Code (NBIC). It is only intended to provide general guidance, and must be used in conjunction with NBIC, Part 2 for specific details of inspection.
This is one of those process safety questions: if 100 engineers were asked, you would NOT get the same answer from all 100. Although there may be other topics, this little fact would also hold true; this aspect of PSM is a critical path in process safety, so we need to get the FACTS on
This report relates to the proof testing of safety instrumented systems (SIS). It has been produced as part of a research project funded by the Health and Safety Executive. The contract was placed with Eutech Engineering Solutions Limited. The objectives of the research were to define a set of guiding principles upon which proof tests of
For those of you who have been using Landview to estimate your populations impacted by your WCS and ARS(s), you may be a tad disappointed to learn that it appears “Landview” will no longer be available with UPDATED data! “Landview 6” was the last update and it used the population data from the 2000 Census
UPDATE: Many thanks to my friends who must remain nameless on my website for sharing their article on this topic. They are MUCH more elegant than me and quite a bit more technical, but all in all we agree… not all safeguards should be counted! For those doubting my position, you need to pay close
It has come to our attention that some manufacturer(s) have changed the design of their auto purgers by installing a Relief Valve (RV) with the package. The owner’s manual of the component specifically lists the RV as a pre-assembled component and requires the installation of a “vent line” on this RV. This seems to be
Are you tired of spending thousands of dollars on high-cost nitrogen to pressure test your process piping? Are you tired of all the procedural documents you must have in place to perform this testing? And all of the training you must do for the personnel performing this testing? Well, I have a special deal for
Take notice where the highly saturated vapor is going… to the ground – NOT rising!
“Now there’s something you don’t see every day” is the quote I will never forget when the OSHA CSHO began looking over the PHA. When we asked what sparked his comment, he showed us…
In the world of process safety and piping design, Hydrostatic Relief Valves (HRVs)—often simply called thermal relief valves—are the unsung heroes that prevent piping ruptures during periods of inactivity. While a standard Safety Relief Valve (SRV) protects against massive surges or process upsets, the HRV is specifically designed to handle the thermal expansion of trapped
The Environmental Protection Agency (EPA), the Occupational Safety and Health Administration (OSHA), and the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF) (“we”) are issuing this advisory as part of an ongoing federal effort to improve chemical risk management, and to advance safety and protect human health and the environment. This advisory contains information on
How can such a little gauge play such a BIG role in process safety? It is actually quite simple, yet so many relief system designs fail to incorporate them. These gauges are BOTH critical to process safety AND compliance with PSM/RMP. In this article, I will explain what a “tell-tale” gauge is and what purpose
