The examination of the scene was conducted using a systematic approach using a basic method of fire investigation and scientific methodology outlined by the consensus committee of the 2024 edition of NFPA 921, “A Guide for Fire Explosion Investigation,” and the 2022 edition of NFPA 1033, “Professional Qualifications for Fire Investigators,” and other treatises as […]
The old argument that we cannot do Hydrostatic Testing on our piping and must do Pneumatic Testing is as old as I have been dealing with process piping (32 years and counting). I was raised in the process and semiconductor industries, where we ALWAYS did hydrostatic testing, and pneumatic testing was our last resort. But
Using the piping inspection RAGAGEP API 570, one of the first steps in our piping inspections/testing is to establish the “Class” our piping fits into. In most cases, I advise my clients to classify their PSM/RMP-covered piping as Class 1. However, there is a possibility that some flammable liquid piping could be classified in a
Those who know me or have been following my rants for years know my love of Bollards and Jersey Barriers. These simple devices (e.g., PASSIVE engineering controls) can prevent a lot of contact between mobile equipment and process/equipment. But as shown in the image below, Aerial Devices such as JLGs can reach OVER safety barriers,
Take notice… single hose. Means liquid gasoline is going in the tank, but where are the vapors going if there is not a vapor return hose back to the truck? ALSO, the tank has an atmospheric vent pipe somewhere so as to vent vapor pressure should the tank get warmer and the gasoline Vp increases.
Most response groups practice the 2-in/2-out rule during a HAZMAT response. But the devil is in the details when complying with 1910.120(q)(3)(vi). How many have attempted to pick up a grown man, weighing 200+ pounds, while they are donned in a wet Level A suit and carry them out of the Hot/Warm Zone? I can
This can be a sensitive topic at many facilities. I was raised to believe that whenever the pressure-retaining boundary is physically broken during line or equipment opening tasks, the line or equipment MUST be pressure- and leak-tested before being returned to service. I get a lot of hate mail and even more weird looks when
Does the fabricator of a B31.3 piping system still have to pressure test components that are manufactured to a standard listed in Table 326.1 when that standard states that the component is hydrotested as a requirement of the standard?
To quote the IFC committee, “the purpose of performance-based design criteria is to promote innovative, flexible and responsive solutions that optimize the expenditure and consumption of resources while preserving social and economic value.” Section 5001.3 Performance-Based Design Alternative is intended to be compatible with EPA’s RMP and OSHA’s PSM requirements, so it would reduce the burden
In the video, you can see the gas company employees placing the ladder and pulling the hose that runs from the unit with the pipe. In an instant, the hose apparently ruptured, and it shot out; even the final section of the hose, where the dispensing pump is located, was about to hit another worker,
10/28/25 UPDATE: Hydrogen (H2) FATAL Line Break RIP 𝙒𝙝𝙖𝙩 𝙝𝙖𝙥𝙥𝙚𝙣𝙚𝙙? The two deceased workers, identified as Mr K (43) and Mr A (50s), were subcontractors conducting scheduled maintenance on a hydrogen pipeline. The task involved inserting a blocking plate into a pipeline to isolate flow, a process requiring the loosening of flange bolts. The explosion
