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…...

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.

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…...

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…...
