Mr Weed was employed by TSI Incorporated for over 28 years (1979-2008).
He spent his first six years there as manufacturing manager in
charge of instrument manufacturing. In 1985 he moved into
marketing and served as the applications expert for TSI instruments
including air velocity meters and mass flow meters. When the
PortaCount® Respirator Fit Tester Model 8010 was introduced in 1987,
Jeff 's career became focused on respirator fit testing and has
remained so ever since. Mr. Weed guided TSI during the 20-year
evolution of the PortaCount, including the development of the
second-generation PortaCount® Plus Model 8020 introduced in 1991 and
N95-Companion™ accessory introduced in 1998. The development
and frequent maintenance releases of TSI FitPlus™ Fit Test Software
were also driven by Mr. Weed. It's no exaggeration to say that
Mr. Weed "wrote the book" on the PortaCount, as he in-fact did author
the instrument manuals, many associated application documents, and
fit testing expertise is not
limited to the PortaCount or quantitative fit testing (QNFT). In
became a member of the ANSI Z88.10 subcommittee on
respirator fit test methods that resulted in the publication of
the consensus standard, ANSI Z88.10-2001 Respirator Fit Test
Methods. Jeff also participated in the next revision of
that standard (ANSI Z88.10-2010) as co-chairman.
Mr. Weed is also an active member of other respiratory protection oriented organizations including the AIHA Respiratory Protection Committee
and the ISRP
, International Society for Respiratory Protection.
Weed had the honor of serving on the advisory board for the NIOSH No
Fit Test Respirator Workshop administrated by the University of
Minnesota in 2008.
