A total of seven people were taken to the hospital after a chlorine gas leak was reported. The cause of the leak was a truck driver who delivered a chemical to a Water Plant and “unintentionally mixed two chemical compounds in a holding tank.” This then released the chlorine gas “from the tank vent.” The […]
This United States Coast Guard alert supports my expectation that we must demarcate our HAZLOCs. I usually get pushback as the code does not explicitly require the boundaries of our HAZLOCs to be marked in any way. But in reality, if we want workers to respect the hazards of working inside a HAZLOC, then we
A recent marine casualty, resulting in a fire and severe injuries to two crewmembers, highlights the risks associated with:
Imagine the purchasing manager announcing at a staff meeting that the business is changing the supplier for one of your PSM/RMP-covered chemicals. There is nothing special about this chemical; it is a 100% pure solution/gas, so you think nothing is changing. But this chemical has come under a lot of questions by yours truly, and
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.
PRAYERS and RIP 🙏 This is why we NEVER step in puddles… MINE FATALITY – On August 4, 2024, a contractor suffered severe chemical and thermal burns after he stepped into a deep opening in the floor obscured by puddled liquid. The contractor fell into a mixture of hot water and caustic liquid. On September
Frozen food production can be hazardous to workers. Although nitrogen and carbon dioxide can quickly freeze food products if released into the work area, they can displace oxygen in the air, which can be fatal to workers. Fundamental safety and operational precautions, such as systems to prevent nitrogen and carbon dioxide from entering and accumulating
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
Last week I posted the investigation findings from a triple fatality event near my hometown that was caused by a 70+-year-old LPG cylinder that was 33 years PAST its recertification/requalification date AND was overfilled. 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
