Fire extinguishment by an inert gas


Fire Protection News/Highlights 

December 31, 2012  Cold weather increases the odds of fire during refueling of cars, trucks and other vehicles.  The Petroleum Equipment Institute has a video of such a fire (girl involved does not appear to be hurt) and some safety tips on refueling practices.  To access the PEI website, click here.  


October 30, 2012  The Standards Council, at its meeting on October 30, 2012, voted to issue the TIA on NFPA 2001, Standard on Clean Agent Fire Extinguishing Systems, 2012 edition, with an effective date of November 19, 2012.  The TIA clarifies the pipe requirement for inert gas systems.  For more information visit the NFPA website.

March 6, 2012  The NFPA Standards Council issued a TIA on NFPA 75 2009 edition effective March 26, 2012.   Click here to read more.


January 4, 2012  A recent article in the NFPA Journal discussed fire protection in Antarctica.  One can imagine the potential for serious consequences of fire in facilities surrounded by the cold barren landscape of Antarctica.  Replacement of facilities destroyed by fire is not readily accomplished in this harsh environment.  Early in the morning of December 2, 2010 fire broke out on a generator in the McMurdo Station powerhouse.  Click here to read more.


December 14, 2011  Modern computer facilities produce lots of heat and requiring constant cooling to keep equipment functioning.  Loss of cooling in a data center will quickly cause equipment, especially the servers which process data, to overheat and shutdown.  A requirement inadvertantly added to the 2009 edition of NFPA 75 Standard for Protection of Information Technology Equipment now requires shutdown of cooling airflow upon detection of smoke under a raised floor.  GSI's Tom Wysocki is part of a task group seeking to remove the requirement.  Click here to read more.


November 15, 2011  One of the most common questions regarding Carbon Dioxide system design using NFPA 12 is the meaning of the NFPA 12 nozzle codes.  GSI's Tom Wysocki has prepared a video lesson to help answer the question in a very practical manner.  AHJs, system designers, fire protection engineers and others who work with CO2 systems may the find the presentation worthwhile.  For more information or to stream the video, please click here.
