Application
The mask as part of the respiratory protective device ensures an
appropriately tight fit of the user's face against the ambient
atmosphere.The mask as part of the respiratory protective device
ensures an appropriately tight fit of the user's face against the ambient
atmosphere.
The full face mask is not a complete respiratory protective device by
itself, but only a part (facepiece) which connects the device 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 apparatus and compressed air line
breathing apparatus, power assisted filtering devices (turbo filtering
devices) and compressed air breathing apparatus.
The relevant instructions for use of these devices must be observed at
all times. Applicable national regulations covering se-lection and use of
respiratory protective devices must be followed. 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 3S 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 temple 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
encompasses 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 protective 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 according 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, unscrew the valve
housing and remove the inhalation and exhalation 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 temperature must not exceed 50 °C.
See Sect. 5 for cleaning intervals.
3.2 Disinfection
Masks should be disinfected after having been cleaned according to
Sect. 3.1. Information 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 intervals.
4 Maintenance
Maintenance of the full face mask must be performed by the
maintenance technician (or by the user if there is no maintenance
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 components and
functional disorders, especially at the valves. In case of doubt about the
functioning of a component, it must be replaced immediately or the
MSA customer service must be contacted.
During the visual test, adherence to the test intervals according to
Sect. 5 must be observed.
