Modifications of a Hydrogen Skid unit leads to explosion with serious injuries during start-up

A sealed, unclassified electrical control enclosure, part of a listed and certified force-ventilated commercial hydrogen processing unit enclosure, exploded when the equipment manufacturer’s technician pressed the machine stop switch to complete the factory commissioning procedure. The technician was forcefully hit by the flying metal panel holding the switch and sustained serious injuries requiring lengthy hospitalization […]

Where are HAZLOCs normally needed?

WA-OSHA standards were revised a number of years ago, so they are in “plain English.”  These are a GREAT SOURCE of information for anyone looking for a straight forward explanation of OSHA standard requirements.  One particular standard that I found helpful was its Hazardous Location (HAZLOC) explanations. These hazardous locations are classified as follows:

EPA issues RMP/EPCRA ENFORCEMENT ALERT: “Risks of Improper Storage of Hazardous Chemicals at Chemical Warehouses and Distribution Facilities”

Some chemical warehouses and distribution facilities may be failing to properly manage hazardous chemicals as required by federal law. In the past several years, the EPA has visited numerous chemical warehouses and distribution facilities (i.e., companies that process, formulate, blend, re–package, store, transport, and market chemical products) to determine compliance with the Clean Air Act

Technical Analysis: The Risks of Pneumatic vs. Hydrostatic Testing

A catastrophic incident at an engineering facility serves as a definitive case study in the dangers of improper pressure testing. A technician suffered life-altering injuries when a 335-liter (88-gallon) vessel exploded during a pressure test. The root cause was a fundamental failure in hazard control: the company opted to use compressed air (pneumatic testing) instead

EPA finally answers the question: Are “tube” trailers considered a single process?

This has been a huge battle in the power generation and semi-conductor industries!  To me, it is very clear – as soon as the trailer is “dropped”, meaning the semi that was pulling the tube-trailer has been detached, then that trailer becomes a “stationary process”.  EPA has several documents making this point and for those
