For decades, businesses have used the TSI Porta-Count QNFT method to fit test tight-fitting respirators. Today, new variations of this NIOSH-approved method (e.g., Condensation Nuclei Counter(CNC) are faster, and we have seen many organizations adopt these new methods. However, changing our Fit-Testing method may require an MOC. I say “may” as not all PSM processes…...

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…...
Initial findings in an employee’s death show breathing air was compromised while working in a paint booth after the breathing air system unintentionally allowed nitrogen to get into the system. The worker, 61, was found not breathing just after noon on Feb. 24 in a paint booth. This incident occurred in the same area where…...
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...
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…...
The U.S. Chemical Safety and Hazard Investigation Board (CSB) marked the 20th anniversary of the fatal explosions and fires at BP America Texas City Refinery in Texas City, TX, that occurred on March 23, 2005. The tragic incident resulted in the deaths of 15 people and injuries to 180 others. To remember this deadly event,…...
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…...
