Chapter 2
Setting Up and Operating the Model 8026
Particle Generator
Introduction
The Model 8026 Particle Generator is intended to supplement the
naturally occurring particles in the air when performing quantitative
respirator fit tests using the TSI PortaCount
®
Respirator Fit Tester. The
following setup and operating instructions presume this intended usage.
This does not preclude using the Model 8026 Particle Generator for
other applications to generate a moderate concentration of poly-disperse
particles. Some general notes on alternate uses for the Model 8026 are
found at the end of this chapter.
Before setting up the Model 8026 Particle Generator, it is important to
select a suitable location for fit testing.
Selecting a Fit Testing Location
The particle generator may be used with the PortaCount fit tester if
you are unable to obtain the minimum particle concentration.


The Particle Generator or any other sources of particle generation
should be kept at least 6 feet from the PortaCount Pro fit tester during
operations.

For the Particle Generator to function properly, operate the generator
and conduct the fit tests in an enclosed area. A room smaller than
400 sq. ft. would provide the best conditions. Particle generation will not
function as efficiently in an open cubicle area or a very large room.

The Particle Generator and other forms of particle generation should
only be used sparingly, when needed. Often they are only needed in the
morning hours or at the beginning of fit testing. Do
not operate any form
of particle generation if ambient particle concentrations are above
8,000 pt/cc (as per use with full- & half-mask, P100 fit testing) or
800 pt/cc (as per use with N95 fit testing).

Never split the Twin Tubing assembly in order to move the ambient
(blue) tube closer to the Particle Generator.
