DESCRIPTION
The SCOTT HEALTH AND SAFETY M95/M110 Full Facepiece Respirator con-
sists of a full facepiece used in conjunction with a filtration element for protection
against airborne gases, vapors, or particulates.The facepiece is available in two
sizes, Regular and Small. Proper fitting is required prior to use of the respirator.
Fit testing per OSHA Standard 29 CFR Part 1910 or ANSI Standard Z88.2 re-
quires testing in the negative pressure mode using equipment such as a
Portacount®Plus1Respirator Fit Tester. For this, SCOTT facepieces require use
of SCOTT Fit Test Adapter P/N 805628-01 and appropriate negative pressure
testing equipment. This respirator, when properly used, seals against the skin of
theuser’sfaceandremoves harmfulcontaminantsfromtheinhaled air bychemical
reaction or mechanical filtration. The Inhalation Valve acts as a check valve to
prevent the flow of exhaled air through the filtration element. Exhaled air leaves
the facepiece through the exhalation valve. The facepiece alone does not pro-
videany protection againsta hazardous atmospherewithout the useof the 40mm
connector with the proper filtration element attached.
The filter element contains sorbents for the removal of gases or vapors and a
built-in P100 particulate filter for the removal of solid and liquid aerosols at a
minimum efficiency of 99.97%.The purchaser of this respirator is responsible for
determining the atmospheric contaminant present and verifying that the filter el-
ement is appropriate.
1Portacount®Plus is a registered trademark of TSI Incorporated, St. Paul, MN
TheM95/M110facepiece respirator uses a singlecanister which may be mounted
on either the right or left side of the facepiece. The unused facepiece connector
mustbe sealed withthe supplied Connector Plug.AnoptionalSpeechDiaphragm
may be substituted for the Connector Plug.
The facepiece may be fitted with an optional factory installed drinking device that
permits connection of an optional drinking bottle. Follow the guidelines of your
respiratory protection program for use of this feature.
The facepiece alone does not provide any protection against a hazardous atmo-
sphere without the use of the proper filtration element attached.
This respirator is intended for entry into and work in atmospheres containing
contaminantswithadequate warning propertiesin concentrations less than those
immediately dangerous to life or health (IDLH) and which are not oxygen defi-
cient. It may be used for ESCAPE ONLY from atmospheres which contain
concentrations of contaminants which exceed the immediately dangerous to life
and health concentration provided the correct filtration element is used and the
atmosphere is not oxygen deficient.
WARNING
THE FAILURE TO CHOOSE A RESPIRATOR EQUIPPED WITH A FILTRATION ELE-
MENT SUITABLE FOR THE CONTAMINANT(S) IN THE ATMOSPHERE OR LIKELY
TO BE RELEASED IN THEATMOSPHERE MAY RESULT IN THE RESPIRATOR PRO-
VIDINGLITTLEOR NOPROTECTIONAGAINSTTHE CONTAMINATEDATMOSPHERE
LEADING TO SERIOUS INJURY OR DEATH.

WARNING
FAILURE TO FIT THE RESPIRATOR TO THE USERAND TRAIN THE USER IN THE
USE OF THE RESPIRATOR MAY RESULT IN LITTLE OR NO RESPIRATORY PRO-
TECTIONAND MAY EXPOSE THE WEARER TO SUBSTANCES WHICH CAN CAUSE
SERIOUS INJURY OR DEATH.
FACEPIECE FITTING
The protection offered by this respirator will be reduced by poor facepiece fit.
Due to the natural variation in the human facial features, no one size or style of
full facepiece can be guaranteed to fit all persons wishing to use the respirator. It
is essential that respirator facepiece fit be checked before issuing or assigning a
respirator to a user. Facepiece fitting also aids in learning the correct donning
procedure.Use theDONNING PROCEDURE andTERMINATION OFUSES sec-
tions of this instruction when fitting users to the facepiece.
Quantitative Facepiece Testing (QNFT) is a procedure wherein the prospective
respirator user wears a test respirator in a test atmosphere. Associated equip-
ment measures the concentration of the challenge agent which enters the test
respirator compared to the concentration of that agent in the air around the user
to provide a numerical measure of the quality of facepiece fit. The test atmo-
sphere can consist of air contaminated with a small amount of aerosol, vapor or
gas, or with the proper instrumentation, the test atmosphere can be particles
found in ordinary room air.
In the event that a satisfactory degree of facepiece fit cannot be obtained, a
different facepiece size or style may be required to obtain a proper facial fit. If a
satisfactory fit cannot be achieved through the fit testing process, do not use the
facepiece.
In addition, a NEGATIVE PRESSURE LEAK TEST must be performed by the
wearereach timethe M95/M110fullfacepiece respiratoris used. SCOTTHEALTH
AND SAFETY recommends that a NEGATIVE PRESSURE LEAK TESTbe con-
ducted as part of the donning procedure each time a user dons a respirator. See
the DONNING PROCEDURE section of this instruction for details of performing
aNEGATIVE PRESSURE LEAKTEST. IFASATISFACTORYNEGATIVEPRES-
SURE LEAK TEST CANNOT BE PERFORMED, DO NOT USE THE
RESPIRATOR OR ENTER THE HAZARDOUS ATMOSPHERE.
