2 Description
The face blank is made of a special soft rubber compound and assures a snug, comfortable fit and a
tight seal. The face blank is also available in yellow silicone. Some versions of the mask are also avail-
able in small size.
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 fog-free] and then through the check valves into the nose cup.
The exhalation air passes through the exhalation valve directly to the ambient air.

Use
GB
3Use
The mask is either carried using the harness in front of the chest or in the mask container.
In order to protect the inside of the mask from dirt, the harness hook is engaged in the front buckle
when the mask is held in front of the chest.
WARNING!
Ensure that the top of the mask seal only lies on the user's forehead. Hair should not be between the
mask's seal and the user’s skin.
The mask could otherwise leak. This danger also exists for instance for mask wearers with beards or
deep scars in the sealing area.
3.1 Donning the Mask
WARNING!
In order to guarantee a proper fit for those wearing glasses, the 3S Full Face Mask spectacle kit must
be worn since ordinary glasses cannot be worn under the mask.
(1) Spread the harness with both hands.
(2) Position the chin into the chin cup.
(3) Pull the head straps over your head.
Whilst doing so, ensure that the harness is sitting
correctly and not twisted.
(4) If necessary adjust mask and tighten the straps in order
as shown firmly and evenly.
When tightening the head straps ensure that the correct
sequence is followed [Figure Pos. 1 - 3, for EZ harness
Pos. 1].
When using the EZ harness if necessary readjust the
head plate by pulling the loop at the back of the head.

(2) Generate a negative pressure of 10 mbar.
(3) Measure the pressure change after 1 min.
The mask including the exhalation valve meets the requirements if for a moistened exhala-
tion valve and a negative pressure generated inside the mask the pressure change does not
exceed 1 mbar in a minute.
Leaking masks must not be used.
The year of manufacture is located on the valve disc.
The year of manufacture is located on the speech diaphragm.
The testing of the masks for tightness is performed using an applicable MSA test device

3S Full Face Mask – Negative Pressure 14
Safekeeping and Storage
GB
5.6 Visual Test and Function Test
Visual Test
(1) Inspect the mask for possible damages like for example deformations, stickings or cracks. Valve
discs, especially exhalation valve discs, are crucial functional elements of the mask.
(2) Defective or damaged parts have to be replaced immediately.
Functional Test
After assembling the mask the mobile parts, especially the valve discs, have to be tested for unre-
stricted mobility.
6 Safekeeping and Storage
WARNING!
In order to avoid damage to or the deformation of the masks keep no additional loose objects in the
mask container.
For the safekeeping of the mask the mask container should be used. This also applies to masks with
installed filters, except CO and NO filters.
MSA rubber products are protected by an anti-aging agent that can become visible as a light coating.
This coating is harmless and can be removed during cleaning.
To ensure a long life for rubber components, keep them in a cool, dry place that is protected from ultra-
violet radiation, according to ISO 2230:2002, Rubber Products – Guidelines for Storage.
