It is great when I can convince an organization to pressure test and leak test its process piping. However, if this task is not done according to the book, we may have created a serious hazard. Two (2) safety-critical devices are often overlooked during pressure and leak testing, and missing either one or both can…...

This is why we MUST have a Quality Assurance process in our piping installations when welding joins the pipe. The same applies to the construction process vessels; however, most of those are “shop-built,” and we are outside the scope of those vessels. But a “field-erected” vessel would fall into our sphere of control…. Membership Required...

One of the top questions I get in my process safety circles is… Do we have to pressure test/leak test piping that has been opened/modified before we re-introduce the HHC/EHS to the piping? I turn to one of my favorite sources for RAGAGEPs, NFPA, and one of the best NFPA codes is NFPA 58, which…...

Processes that handle Liquified Pressurized Gases are required to have Hydrostatic Relief Valves on liquid piping where the liquid can be trapped. Much like vapor/gas phase Pressure Safety Valves, it is frowned upon when we have an intervening valve under the PSV. However, many codes today ALLOW us to install a 3-way valve below the…...

Now the BSEE has shared a SAFETY ALERT regarding a Nitrogen Compressed Gas cylinder that catastrophically failed injuring three (3) workers…...
The explosion at an auto repair shop in Hillsboro, OH that claimed the lives of three (3) workers, aged 19, 33, and 47 in 2023 has been determined to have been caused by a rupture to an LPG cylinder that had been overfilled and past its requalification date by 33 years. I would also like…...

A video I posted over two years ago has come full circle. A citizen (some may call him homeless) was allowed to sit (and smoke) within 20′ of a gasoline tanker unloading operation at a gas station. His actions may not have been his sole demise, as we can see in the video evidence that…...

A soft drink manufacturer had a 3-ton capacity carbon dioxide (CO2) receiver tank at the plant. The tank contained 2000 pounds on the day of the explosion. The establishment was evacuated due to flooding river waters in the area. The plant was secured and evacuated. No employees were at the workplace. Suddenly, the storage tank…...
