I am teaching Compressed Gas Emergency Response classes all week at Global Foundries in Malta, NY where they handle many highly toxic, explosive or violently reactive materials. When I am here I always have lunch or dinner with Al Mossman who was the former President of Matheson Gas Products. He was the first engineer that Matheson hired in 1952. He was the first generation of compressed gas industry technologist in the days when handling the exotic gases was a mystery. There were many fatalities and explosions during the 1950-1980 time frame. He wrote the infamous Matheson Gas Data and Medical Treatment Handbooks. My successful career is due to his mentoring. I am now commited to passing along my learnings to the 5th generation of gas technologist so that accident history does not repeat itself.

I was down memory lane today. In 1989 I designed a portable pressure vessel that could be used to isolate and transport a leaking compressed gas cylinder for use at Solkatronic. AT&T our largest customer convinced me to sell them one in 1991 to their Reading, PA facility. I named these ERCV’s (Emergency Response Containment Vessel) because I did not like it being called a Cylinder Coffin. ERCV or a Solkatronic has become synonymous with these types of emergency devices (Goggle ERCV or Solkatronic). In over 25 years, there have been over 400 of these sold to users (FDNY, FBI HMRU, Taiwan EPA, etc) around the world. These have been used safely on numerous Hazardous Materials incidents involving toxic, corrosive, pyrophoric or reactive gases.

When AT&T closed the Reading facility, they donated the 5502 ERCV to the Reading Fire Dept. In over 10 years they have not had an occasion to use the unit. They contacted me to see if I could sell it to another user. This unit however will require a major overhaul, testing and maintenance before it can be sent out into the field again. I was a proud father to once again see my second “ERCV”. I brought it to the first stop in the journey to bring it back into operation for another 25 years!

I'm extremely frustrated and sad. I just received e-mails from 2 retired Firefighters from Florida who sent me articles on a tragic accident a few days ago that killed a worker and injured a second. I helped them investigate a similar incident over a year ago. There has been over 4 explosions in Florida and 4 in California with companies filling cylinders without a good understanding of the hazards, yet they continue. To help spread the word, they wrote an article for Fire Engineering and I wrote the following

I had hoped that people would have learned from this


2015 was another great year. Over 20 safety and ER training classes/presentations
