Two people were severely injured after a Nitrogen cylinder catastrophically failed during refilling/pressurization. Person 1 shut off the air and nitrogen gas supplies before yelling to the workshop to call the HSE leader (nurse). Person 2, who was holding the cylinder, suffered severe injuries to his legs and one hand. Person 3 was injured when the booster pump collided with his legs, probably after...

The investigation has found that the direct cause of the leak was corrosion under the insulation in a 4″ pipe for heavy naphtha from the distillation tower.  The lack of inspection and repair meant that the corrosion had continued long enough for a hole to form in the pipe. Piping and equipment in a refinery can be exposed to external and internal corrosion. To monitor and repair such damage,...

BOYLES LAW:  When the temperature is kept constant, the volume of a gas is inversely proportional to the pressure upon it. CHARLES LAW:  When the external pressure is kept constant, the volume of a gas is directly proportional to its absolute temperature. … HomeRead More »

Every day of the year, billions of cubic feet of gas are stored, transported, and used without any problems or mishaps. This results from a conscientious, solid – effort toward safety within the gas industry. Even with this effort, from time to time, something goes wrong; either mechanical or human error occurs. When this happens, a hazard to man and his environment may evolve. Because of the...

I got this document when I attended a National Fire Academy HAZMAT course in 1993.  I came across it when looking for some old HAZMAT material for a new course I am developing and translated and cleaned up some of the language.  It does an EXCELLENT job explaining the phenomenon we know as BLEVE (Boiling Liquid Expanding Vapor Explosion)   Crescent City, Illinois, propane explosion occurred...

This picture has caused quite the debate in the SAFTENG circle! Many comments in the SAFTENG LI and FB groups point towards the worker(s), which indicates the belief that this is an “Active Failure” of the worker(s) involved. Many of you would NOT believe the tales I could tell about what I have encountered in my travels in 20+ years of consulting.  In the vast majority of these situations,...

OSHA states the following about our non-entry rescue devices… The mechanical device used for emergency rescue must be designed and rated for human use. The standard specifies in paragraph 1910.146(k)(3)(ii) that the retrieval equipment must be designed for personnel. The performance-oriented nature of the standard allows flexibility as to the design specifications of the retrieval equipment itself....

In Reason’s Swiss Cheese model, there are four “slices “or tiers of human error potential, divided into two sections: an “active” layer and “Latent Factors”: preconditions, Supervision, and Organization. The goal of the Human Factors Analysis and Classification System (HFACS) is to understand human factors throughout the system rather than stopping at the operator. Most mishaps can be connected...
