Contractor Safety – Evaluation Tip

Recently a former client was cited for hiring a contractor who was not qualified for the work they were hired to perform.  Also, do not lose sight of the fact that this contractor was NOT cited for any OSHA violation as they did not violate their responsibilities under 1910.119(h)(3), although some may argue they violated […]

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

Once again EPA attempts to explain their CONCENTRATION QUALIFIERS concept

I have written often about this topic and it is without a doubt the most questioned/challenged topic in my 5-Day Advanced Process Safety course.  Several toxic substances are listed as regulated substances under 40 CFR §68.130 with CONCENTRATION QUALIFIERS (e.g., “conc 37% or greater”).  The four(4) regulated substances that have concentration qualifiers are: Ammonia (conc

Modications to pressure/vacuum relief devices allows for catastrophic failure of container

HAZMAT containers used for flammable, corrosive, and toxic liquids and gases will have a pressure/vacuum relief valve to prevent damage to the tank from changes in the internal pressure. These valves MUST be inspected and maintained in line with the manufacturer’s instructions.  Some valve designs require a special tool to dismantle them for servicing. Investigations
