1 Designation, Marking and Application
Full face mask Designation
Faceblank
MSA AUER
3S-Basis Plus AUER 3S-Basis Plus
The full mask 3 S-Basis Plus meets the currently valid guide-
lines for testing and approval. It meets EN 136, class 2, and
is in accordance with Directive 89/686/EEC.
Application
The full face mask is not a complete respiratory protective de-
vice by itself, but only a part (facepiece) which connects the de-
vice with the respiratory tracts of the user. It serves as facepiece
(EN 136, class 2) with standard thread connection (EN 148 -1)
for respiratory protective filters, fresh air hose breathing appara-
tus and compressed air line breathing apparatus, power assist-
ed filtering devices (turbo filtering devices) and compressed air
breathing apparatus.
The relevant instructions for use of these devices must be ob-
served at all times. Applicable national regulations covering se-
lection and use of respiratory protective devices must be fol-
lowed. When used in potentially explosive areas the full face
mask must be treated with an antistatic spray or a water mist
must be used.
Users with facial hair like beards or sideburns are not likely to
achieve a tight seal, since the hair will break the facepiece-to-
face seal.
Persons requiring corrective eyewear must use the prescription
spectacles 3 S in order to get a tight facepiece-to-face seal.
2 Design, Functioning and Use
Design (Fig. 7)
The inhalation air flows from the connector of the mask past the
inhalation valve to the inside of the lens (thus keeping the lens
largely free from fogging) and from there through the check
valves into the nose cup. The exhalation air passes directly
through the exhalation valve to the ambient atmosphere.
2.1 Stand-By
For stand-by the mask is stored in a carrier or carrying bag to
protect it against dirt.
2.2 Donning
Spread the head harness apart with both hands and first place
the chin into the chin stop. Pull the harness over the head (make
sure that the straps lie flat against the head) and tighten the

straps evenly and firmly, starting with the neck straps, then tem-
ple straps and lastly the forehead strap (Fig. 1 and 2).
Note:
This sequence must be maintained under all circumstances in
order to assure that the center section of the harness encom-
passes the back of the head!
2.3 Tightness Check
In order to check the facepiece-to-face seal, a tightness check
must be performed. To do this, cover the connector opening or
the entry opening of the filter with the palm of the hand (palm
test, Fig. 3). When inhaling and holding the breath no air shall
leak in. The check has to be performed before each use. A more
reliable tightness check is with the complete respiratory protec-
tive device in a test chamber.
2.4 Removal
To loosen the head harness, push the buckles forward with the
thumbs (Fig. 4).
Then grasp the mask by the connector and pull it backwards
over the head (Fig. 5).
3 Cleaning and Disinfection
Note:
After every cleaning and disinfection a tightness test accord-
ing to Sect. 4.2 must be made!
3.1 Cleaning
The dirty mask is cleaned with lukewarm water containing a
mild detergent. Prior to washing, take out the nose cup, un-
screw the valve housing and remove the inhalation and exhala-
tion valve discs.
These components are cleaned separately and reassembled only
after drying. Cleaned parts must not be dried in radiant heat
(sunlight, radiators). When using a drying cabinet the tempera-
ture must not exceed 50 °C. See Sect. 5 for cleaning intervals.
3.2 Disinfection
Masks should be disinfected after having been cleaned accord-
ing to Sect. 3.1. The AUER disinfectant 90 is recommended. In-
formation about the concentration and time is contained in the
instructions for use of the disinfectant. After disinfecting
thoroughly flush all components with water as described in
Sect. 3.1, dry and reassemble. See Sect. 5 for disinfection inter-
vals.
4 Maintenance
Maintenance of the full face mask must be performed by the
maintenance technician (or by the user if there is no mainte-
nance technician). It includes visual, functional and tightness
tests, as well as replacing components.
4.1 Visual and Function Test
The visual and function test serves to identify damaged compo-
nents and functional disorders, especially at the valves. In case
of doubt about the functioning of a component, it must be re-
placed immediately or the MSA AUER customer service must be
contacted.
During the visual test, adherence to the test intervals according
to Sect. 5 must be observed.
