In presenting the award NFPA noted:

"Thomas Wysocki of Guardian Services, Inc. in Frankfort, Illinois serves on:  The Technical Committees on: Carbon Dioxide Fire Extinguishing Systems (1979 - 2005) (this TC was discharged in 2005 and became part of the Gaseous Fire Extinguishing Systems committee), Halogenated Fire Extinguishing Systems (1979 2005; Chair 1991 - 2005) (this TC was also discharged in 2005 and became part of the Gaseous Fire Extinguishing Systems committee),  Electronic Computer Equipment (1988 Present ; and Chair 2000 - 2009), and Gaseous Fire Extinguishing Systems (2005 Present)Thomas also received a Special Achievement Award in 2003."

August 5, 2009

The National Fire Protection Standards Council recognized Guardian Services' Tom Wysocki for his "dedicated service and leadership as Chair of the Technical Committee on Electronic Computer Systems." Tom has served on the NFPA 75 Technical Committee for over two decades and recently completed his tenure as Chair of that Technical Committee. Wysocki will continue to serve as a Principal member of NFPA 75.

Tom said, "The members of the NFPA 75 committee have truly been a pleasure to work with. They are dedicated to safety and bring common sense as well as vast experience. I am very pleased that the Standards Council has appointed Ralph Transue, former Chair of NFPA 76, to serve as the new 75 committee Chair. Ralph is a dedicated and very knowledgable leader - I look forward to continuing on the committee under Ralph's leadership."

NFPA Special Achievement Award to Sam McTier and Tom Wysocki

At the opening session of the NFPA Fall Meeting (Reno Nevada, November 17, 2003), Phillip DiNenno, chair of the NFPA Standards Council, presented Sam McTier and Tom Wysocki, two dedicated volunteers, with the Awards at the Opening Session. NFPAs Special Achievement Award recognizes the significant contribution of a committee member to a single project that has enhanced the NFPA codes-and standards-making process.

In presenting GSI's Tom Wysocki this award, Phil DiNenno noted that Tom has been active in NFPA codes and standards developments since the 1970s. As chairman of the NFPA 12A Technical Committee on Halon 1301 system, he guided the standard as the world scientific community determined that the Freons, including Halons, were contributing to depletion of the stratospheric ozone layer. To protect the ozone from further depletion, the NFPA 12A standard was modified to minimize emissions of Halon 1301 and provide an orderly transition to non-ozone depleting extinguishing agents.

Tom has presided over the NFPA 75 Technical Committee on protection of computers during an era when the nature of computer facilities underwent dramatic change. The NFPA 75 Standard has recognized and kept current with the changing nature of technology information systems.

And Tom is a long tenured member of NFPA 12 Technical Committee on Carbon Dioxide systems. His expertise in the safe and effective use of these systems is well respected.

NFPA 2001 2011 Edition includes New Minimum Design Concentrations

NOTE:  The current Edition of NFPA 2001 is the 2018 edition.  The following information released in 2011, however, is still mandated by the 2018 edition.  NFPA 2001 will be entering the Fall 2010 revision cycle.

In August 2011, the NFPA
Standards Council released a revised NFPA 2001 having the following requirements for minimum design concentration for Class A and Class C fires:


For Class A hazards, the minimum design concentration will be the greater of


1.2 X the minimum extinguishing concentration for Class A fires determined by the UL/FM listing tests or


the extinguishing concentration for normal heptane determined from the cup burner test.


The effect of this expected change would be to increase the Class A MDC for systems using halocarbons. The Class A MDC for systems using inert gases would be unchanged since all of the current Class A MDC for inert gases are greater than or equal to the MEC for n-heptane. Shown below are the MEC for n-heptane taken from Table A.5.4.2(b) of NFPA 2001 Standard Edition 2008 for some of the more common halocarbon agents:


MEC for n-heptane

FK 5-1-12








For Class C fire hazards, the minimum design concentration will be as follows:

The minimum design concentration for Class C hazards will be 1.35 times the minimum Class A extinguishing concentration for Class C hazards determined by paragraph of NFPA 2001 where the supply voltage to equipment is 480 Volts or less. The new Class C minimum design concentration requirements are to read as follows: The minimum design concentration for a Class C hazards shall be the extinguishing concentration, as determined by, times a safety factor of 1.35. The minimum design concentration for spaces containing energized electrical hazards supplied at greater than 480 volts which remains powered during and after agent discharge, shall be determined by testing, as necessary, and a hazard analysis.

Fire Protection Handbook

The 19th Edition of the NFPA Fire Protection Handbook is now in print. Tom served as editor for the chapter covering Carbon Dioxide Fire Extinguishing Systems.
