Only use these equations if the contaminants present are actually mixed. Some
substances do not mix and may be present separately, for example, in pockets or
at different levels. In that case, the lowest TLV of the substances present must be
used to determine the appropriate respirator category for protection against all con-
taminants present.
See MSA’s Response Respirator Selector (available online at www.msanet.com) for
additional information.
RESPIRATOR FIT TEST
A qualitative or quantitative respirator fit test must be carried out for each wearer of
this respirator to determine the amount of protection it will provide. Respirator fit
tests are explained fully in the American National Standard for Respiratory
Protection, ANSI Z88.2, which is published by the American National Standards
Institute, 11 West 42nd Street, New York, New York 10036.
Quantitative Test
If a quantitative fit test is used, a fit factor that is at least 1,000 for a full facepiece
respirator and 100 for a half-mask respirator shall be obtained before that respira-
tor is assigned to an individual.
Qualitative Test
If a qualitative fit test is used, only validated protocols are acceptable. The individ-
ual must pass a test designed to assess a fit factor of at least 1,000 for a full face-
piece respirator and 100 for a half-mask respirator.
Duo-Flo Respirators must be qualitatively or quantitatively fit tested in a negative-
pressure mode. This will cover use of the respirator in both air-purifying and air-sup-
plied modes of operation.
The user must perform a respirator fit test and follow all warnings and limita-
tions specified. Failure to do so can result in serious personal injury or death.
BEFORE USE
1. Make sure certain conditions of exposure are (a) within the limits for which the
device is approved (see appropriate NIOSH approval plate) or, (b) within the lim-
its established by MSA for the particular cartridge (see cartridge label).
