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 5.4.2.2 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:
5.4.2.5 The minimum design concentration for a Class C hazards
shall be the extinguishing concentration, as determined by
5.4.2.2, times a safety factor of 1.35.
5.4.2.5.1 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.

Recognized by NFPA
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.
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.
