NOTE the focus on PRESSURE TESTING after a repair/alteration! Today, the U.S. Chemical Safety and Hazard Investigation Board (CSB) released a new safety video on its investigation into the massive April 8, 2021, explosion and fire that fatally injured one worker at the Yenkin-Majestic Paint Corporation facility in Columbus, Ohio. The CSB’s new safety video, […]
Section 5189.1. PROCESS SAFETY MANAGEMENT FOR PETROLEUM REFINERIES Amend Subsection (c) Definitions.
A contractor was injured and evacuated after a gas release incident on an offshore facility in the Gulf of America. The incident occurred while a contract employee was performing maintenance on an E-body control valve on a six-inch gas line. BSEE’s investigation found that residual pressure estimated at 128 psi inside the six-inch gas line
At 1:40 p.m. on May 7, 2024, Employee #1, 42, a Production Engineer, was performing daily assigned tasks when the Maintenance Coordinator requested that the employee replace a gasket on a wash tank camlock. While disconnecting a high-pressure hose from the bulk wash tank, the hose ejected water at 185F. The hot water burned 98%
At 10 p.m. on 3/19/18, an employee, 34, and coworker were performing preventative maintenance on a chlorine gas system used in a water filtration process. The employee and coworker were removing, and reinstalling, a flange with a black Teflon rubber gasket. They were working in a 48-foot long, 24-foot wide, and 6-foot tall crawl space
At 11:05 a.m. on September 17, 2020, an employee, 34, was working for a water treatment support services company. He began to take a bolt off the motor of a distribution pump on a chlorine dioxide generation system (Unit #2).
We have discussed the pros and cons of pressure testing/leak testing piping. Code requires the test to be Hydrostatic Test; but if there is a legitmate issue with doing a hydrostatic test, then we can use the pneumatic test method. But we MUST realize the catastrophic/fatal hazard of pneumatic testing. For example,
Corrosion allowance is the extra thickness of metal added to a component to account for material loss from corrosion over its service life, ensuring it can withstand pressure and structural loads until the end of its designed life. It is calculated based on the predicted corrosion rate, operating conditions, and the equipment’s anticipated life, using
ASME PCC-3 guides the preparation and implementation of a risk-based inspection plan. Flaws identified during inspection plan implementation are then evaluated, when appropriate, using the procedures provided in API 579-1/ASME FFS-1, Fitness-for-Service. If it is determined that repairs are required, guidance on repair procedures is provided in ASME PCC-2, Repair of Pressure Equipment and Piping.
This debate seems never to die, and I keep adding more examples to make my point crystal clear… When pressure- and leak-testing piping, we are to use the Hydrostatic Method rather than the Pneumatic Method. ASME provides three (3) specific situations in which we can use Pneumatic Testing instead of Hydrostatic Testing. And these exceptions
A plant worker died following an exposure to hydrofluoric acid at a chemical plant in St. Gabriel. Two workers with burns were taken from the plant to a hospital where one of them died during surgery. company statement: (scrubbed by me)
I am not a fan of “government”, but I am a fan of so many of the workers within our government. They can do some fantastic work. Take this latest and greatest tool for Chemical Safety, for example. This is just too “cool,” and if you are into HAZMATs or Chemical Safety, this is a
