SIZE SELECTION
Regardless of facial dimensions and respi-
rator sizing charts, an actual respirator fit
test, either qualitative or quantitative must
be performed to ensure the correct respira-
tor size selected.
Fit test the respirator size relative to your
facial features and dimensions. The Safety
Administrator or Program Manager might
assist in selecting the initial size to try.
Carefully don the respirator and conduct a
negative pressure seal test. See donning
instructions for procedure.
If the respirator does not pass the Negative
Pressure Seal Test or feels uncomfortable,
try the next nearest size relative to your
face.
Passing the Negative Pressure Seal Test
does not verify the size is correct. The size
selected must be verified by successfully
passing a Respirator Fit Test, either qualita-
tive or quantitative. If the respirator passes
a Negative Pressure Seal Test but DOES
NOT pass a Respirator Fit Test, the next
nearest size relative to your facial features
and dimensions should be tried.
Once the proper size is selected, the respi-
rator must pass a Negative Pressure Seal
Test every time the mask is donned to
ensure proper fit before using the respirator.
If other than facial seal leakage is detected,
the condition must be investigated and cor-
rected before another test is made.
The respirator must also pass the tightness
test before the user attempts to enter an
toxic atmosphere.
The mask will not furnish protection unless
all inhaled air is drawn through a suitable
canister/cartridge(s).
RESPIRATOR FIT TEST
The user must perform a respirator fit
test (Quantitative Test or Qualitative Test)
and follow all warnings and limitations
specified. Failure to do so can result in
serious personal injury or death.
A qualitative or quantitative respirator fit test
must be routinely carried out for each wear-
er of this respirator to determine or confirm
the amount of protection that the respirator
provides. The fit test method chosen may
impact the maximum use concentration.
Quantitative Test: — If a quantitative fit
test is used:
For use in a CBRN application a fit factor of
at least 2000, based on ambient aerosol fit
test methods or equivalent, is required
before any type of respirator is assigned to
an individual.
Qualitative Test — If a qualitative fit test is
used, only validated protocols are accept-
able.
For use in a CBRN application only, the
individual must pass a test designed to
assess a fit factor of at least 2000.
Respirator fit tests are explained fully in the

Respiratory Protection, ANSI Z88.2-1992

National Standards Institute, 11 West 42nd
