On February 18, 2020, the audible alarm and light outside the Ammonia plant was activated at approximately 6:40 pm. The plant operator checked the NH3 (ammonia) readings and it read 43 ppm (parts per million). At 6:45 pm the readings increased to 51ppm and staff activated the Emergency Response Plan, contacted 911, the Chief Engineer, […]
Two persons received minor injuries from exposure to ammonia after a refrigeration system failed and released ammonia that was intended to be contained within the evaporator and refrigeration system. INCIDENT OVERVIEW The evaporator within a refrigeration system of an industrial food processing facility failed and released ammonia in a cold storage room. Two workers suffered
A hydrogen leak originating from a tank within a high-pressure storage unit serving a hydrogen vehicle fueling station resulted in fire and explosion. Emergency responders were on scene within 7 minutes and contained the fire within 3hours. No damage was reported to the separate forecourt H2 dispenser or to other major station components within the
Recently a fire district posted a video of a HIT occurring on a gasoline storage tank at a residence in Alaska. In their posting, they called the event a BLEVE and technically speaking we can see (as I show below) that this event was NOT a BLEVE. A Boiling Liquid Expanding Vapor Explosion (BLEVE) is
A safety feature(flanged connection)failure in a refrigeration system released 10 to 20 lbs of ammonia intended to be contained. The ammonia refrigeration system is designed to operate at 250 Psig. The system uses welded or flanged connections to connect components such as compressors, condensers, evaporators, and liquid receivers. Piping and fittings including flanges, different types
PSM/RMP covered processes that operate above 15 psi will have relief valves to protect pressure containing components such as vessels, piping, pumps, compressors, etc. It is standard practice that these relief valves get changed out at least every five (5) years or so; please follow your RAGAGEP and/or the RV manufacturer instructions for specific change/test
A baseline of every 5 years is recommended; however, there are some critical exceptions that would require more frequent inspections. And if the process is CLEAN (e.g., Non-Fouling), we could go 10 years WHEN the manufacturer permits. Here is a breakdown of these frequencies, using API 576 and NB Part 4.
ASME B31.3 does not permit the use of an “ASME Section V Pressure Change Test” as a substitute for the mandatory leak testing requirements (hydrostatic, pneumatic, or initial service leak test) defined in Chapter VI of the B31.3 Code. Why It Cannot Be Used as a Substitute:
Sorry, I have not seen any actual citations or details of how this incident occurred, but I will update if I get anything. A chemical supplier and an Ingredients’ facility have been fined $1 million each for violating the federal Clean Air Act when a cloud of toxic chlorine gas was released over Atchison, Kan.,
Today, the EPA’s RMP Info Center published the following guidance on the REVISED emergency coordination activities in the RMP Rule. The Risk Management Program regulations require owners and operators of stationary sources to coordinate their response needs ANNUALLY, or more frequently if necessary, with local emergency planning and response organizations (40 CFR §68.93(a)). Are stationary
