I love the CSB’s work, but this study could have been said in really simple terms… State Fire Code(s)! I have written dozens of articles explaining the specific requirements of the International Fire Code (IFC), from which most of the 50 states have adopted some “revised” version. Chapter 50 of the IFC (and those states…...
Many thanks to my friend in safety down under, Mr. Peter Hunt, Director and Principal Consultant, Whamcorp Pty Ltd On 25 March 1991, a contractor died after an ammonia tank he was upgrading exploded at the ICI plant.

The Hydrant and PIV must be protected, so we installed two (2) “lazy bollards.” The post are correct, their installation is NOT to code. Had they been installed in the parking lot with a 15” diameter footing and at a height of 4’ AND 4’ away from the PIV, then all would be OK. But…...

In 2012, I discussed the use of sulfur sticks and asked a question: Sulfur sticks and ammonia leaks… are you in compliance when using these leak detection devices? In 2014, IIAR updated its edition of ANSI/IIAR 2 – Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems, which PROHIBITS their use when charging is being…...

In almost every PHA I have done since 2000, we find safety critical valves or instrumentation with a built-in bypass around them. I understand the need for a bypass WHEN IT IS FOR MAINTENANCE of the device, but in no sane world do we put a bypass around a safety-critical device so that the process…...

The operators of a global ink and coatings manufacturing company could have prevented an employee from suffering burn injuries from a flash fire that erupted in an industrial mixing vessel containing flammable liquids and vapors by following federal regulations for handling of highly hazardous chemicals. An OSHA investigation determined a flash fire sparked in the…...
How many code/RAGAGEP violations can you identify? Tip: Code(s) and RAGAGEPs require equipment to be protected against contact with mobile equipment when that contact could lead to an LOPC event involving a hazardous material.

While anhydrous ammonia has many environmental and operational benefits, it is also an extremely hazardous substance that, if accidentally released, presents a significant health hazard because it is corrosive to the skin, eyes, and lungs. Ammonia is also flammable at certain concentrations in air. The Environmental Protection Agency (EPA) would like to work with facilities…...
During a recent offshore inspection, a BSEE inspector observed operator personnel installing a 100-foot high-pressure hose, with a Maximum Working Pressure (MWP) of 5000 psi, to test pressure safety valves on pipeline pumps. The hose used was designed for hydraulic fluid and not suitable for high-pressure nitrogen; when nitrogen gas at 2500 psi was injected…...

Lithium-ion battery manufacturing has garnered a lot of news lately, both good and bad news. Although these batteries are being manufactured in the name of being “environmentally friendly,” as is the case in many PSM/RMP-covered processes, the raw materials used in their manufacturing are anything but “friendly.” The PSM process in this manufacturing process involves…...

We have discussed pressure and leak testing piping in our hazardous materials processes, specifically in our PSM/RMP-covered processes. The International Fuel Gas Code (IFGC) has some great specifics on how we test natural gas piping. Interestingly enough, the IFGC code defines “pressure test” as… (emphasis by me) An operation performed to verify the gas-tight integrity…...
