A friend has shared some info regarding a new fixed foam system for tank fire!  The video is amazing to watch, especially if you have spent anytime on a hose line at a large diamater tank fire!  This company is apparently very new and is focusing their efforts in Europe for now, but man is this ever needed here in the USA.  I have no idea as to cost, but you can learn more about them...

At the heart of any relief system design basis are the “scenarios” chosen to base the sizing of the relief system.   The two most common scenarios used are the “fire scenario” and the “blocked-in scenario”.   It is the fire scenario I wish to review in this article and what has to go along with this scenario. An external fire impinging directly on the shell of a pressure vessel...

This month marks the 20th anniversary of OSHA’s Process Safety Management standard, which is built upon Recognized and Generally Accepted Engineering Practices (RAGAGEP).  There was no way OSHA could write a “specific” standard to cover all the types of processes handling the list of Highly Hazardous Chemicals (HHC) so they instead wrote what is called a “performance oriented standard” that is...

This was a utility coal fired boiler at 11:30 am but at 12:15 pm it was basically scrap metal. The plant had just finished an outage and was in the process of placing the boiler back online. The furnace was started on natural gas and once it had reached a certain point it would switch over to coal. The unit was being filled after the outage and the manual gas valves had been turned on. When the boiler...

The presence of passengers in a vehicle has been shown to increase the risk of fatal crash involvement for teenage drivers; however, the studies that have quantified this relationship were based on data that are now over a decade old. In the years since these studies, most U.S. states have enacted graduated driver licensing systems that limit the number of passengers that young...

Auto-refrigeration is a phenomenon common to Anhydrous Ammonia. Anhydrous Ammonia exist in both the liquid and gaseous phases at ambient temperatures with pressures ranging from 2 psig up to 2,500 psig. That is, there is a gaseous layer over the liquefied gas within the pressure vessel. … HomeRead More »

The 2011 addenda of the ASME Boiler and Pressure Vessel Code includes a new ASME Code stamp which replaces all of the current ASME pressure relief device stamps (V, HV, NV, UV, UD, TD). The new ASME stamp is the same for all Code stamped items, and is accompanied by a “designator” which identifies the specific product. The designator consists of the letters that were part of...

Children and adults alike have been injured using flammable liquids such as gasoline. Most incidents involve a flammable liquid used on an outside fire such as burning trash, a bonfire, or a brush fire. Each year thousands of emergency department-treated injuries are related to flammable liquids. Of the people injured, 87% were male. Vapors from some of these liquids are highly...
