During a recent offshore inspection, a BSEE inspector observed operator personnel installing a 100-foot high-pressure hose, with a Maximum Working Pressure (MWP) of 5000 psi, to test pressure safety valves on pipeline pumps. The hose used was designed for hydraulic fluid and not suitable for high-pressure nitrogen; when nitrogen gas at 2500 psi was injected…...

The NY City Bridge got hot because the drive train that moves it overheated, NOT because “climate change” or ambient temperatures caused the bridge to “swell.” I am not a metallurgist, but I did stay at a Holiday Inn Express last week. If this bridge can not operate within its design tolerance because the ambient temps…...
Lithium-ion battery manufacturing has garnered a lot of news lately, both good and bad news. Although these batteries are being manufactured in the name of being “environmentally friendly,” as is the case in many PSM/RMP-covered processes, the raw materials used in their manufacturing are anything but “friendly.” The PSM process in this manufacturing process involves…...

We have discussed pressure and leak testing piping in our hazardous materials processes, specifically in our PSM/RMP-covered processes. The International Fuel Gas Code (IFGC) has some great specifics on how we test natural gas piping. Interestingly enough, the IFGC code defines “pressure test” as… (emphasis by me) An operation performed to verify the gas-tight integrity…...

On March 3, 2009, at approximately 1:29 p.m., Employees #1 and #2 were conducting a gas line pressure test on a 20-inch gas line. The test involved pressurizing the line to 100 psi and holding this pressure for one (1) hour. This test was conducted to determine whether the gas line being tested could be…...

On May 18, 2023, at 7:45 p.m. an employee, 45, working for a paint and coating manufacturer was wearing a 3M half-face respirator while spray coating MacroPoxy 646 Fast Cure Epoxy on parts. The employee was spraying the last parts of the day when he began feeling chest pain. The employee used his inhaler twice…...

Without question, the #1 question we receive regarding Hazardous Locations is… When do I need one? With flammable liquids (e.g., FP<100F) it is easy to perform the evaluation. But what if my flammable solution is a CAT 3 or 4 (i.e., Class IIIA or IIIB)? As the title says, not all flammable solutions require us…...

A tank cleaning company again chose to disregard federal safety standards that may have protected their employees from hazardous working conditions and prevented another employee from suffering a fatal injury. In December 2023, just two days before Christmas, the wife and son of an employee at the company grew concerned when he didn’t return after…...

Any safety pro who is also a parent will know exactly what I am discussing with this week’s rant. As parents who are leaders in safety, we have all seen it and experienced it firsthand throughout our careers. Every child will be different (even within the same family and home environment), as will every facility…...

I have written a lot about leak testing and pressure testing our piping systems and those articles all mention using the “bubble test” method. Now lets talk about the actual requirements of this test method. ASME B31.3, 345.8 Sensitive Leak Test refers us to ASME BPVC, Section V, Article 10, Mandatory Appendix I, for how…...

This BLEVE occurred on the BR-010 highway in Paragominas, northeast of Pará, Brazil, on July 3, 2024. At least six people were injured, including firefighters and a news crew (July 3, 2024). The news crew suffered second-degree burns but received medical attention at a Regional Hospital and are expected to make full recoveries. The news…...
