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…...
The arrangement below is very common in processes/systems. This simple yet common arrangement causes havoc in hazard analyses. As the title states, is this arrangement managed with a Temporary SOP, a Car-Seal, or Both? The issue is that the motorized valve is tied to a Hi-Hi level alarm and interlock. When the vessel archives its…...
Several clients design Double Block and Bleed (DB&B) isolation into their process, especially when they know they will regularly enter certain Permit-Required Confined Spaces (PRCS). When these DB&B arrangements are part of the design, the isolation valves and the bleed valve are near one another. This allows us to use a single lock with some…...
We often encounter an organization that conducts LOTO training annually. They do this because they believe OSHA requires annual LOTO training. However, the standard, 1910.147, does NOT require annual training! The standard requires each authorized employee to be “inspected” annually. If they fail that inspection, the standard requires the authorized employee to be re-trained. OSHA…...
In the past several decades, some organizational researchers and managers have used it to describe the norms and practices that organizations develop around their handling of people or as the espoused values and credo of an organization. This sometimes confuses the concept of culture with the concept of climate, and confuses culture as what is…...
Contributing to the severity and duration of the fire was the lack of storage tank fail-safe control valves and internal fire valves and the location of the control building in the containment area where fuel leaks are likely to occur. The National Transportation Safety Board determined that the probable cause of the fire at the…...
