1 Safety Regulations
1.1 Correct Use
Series 3S-Basis Plus Full Face Mask with standard thread connection according to EN 148-1 are not complete
respiratory protective devices by themselves, but serve as facepieces [EN 136 CL2] for use with respiratory filters,
compressed air breathing apparatus, fresh air hose breathing apparatus and compressed air line breathing
apparatus.
The type and concentration of contaminants and the oxygen concentration in the ambient air must be known to
decide if the use of a filtering device is permissible. The instructions for use of the respiratory filters have to be
regarded, including any information regarding the use in potentially explosive atmospheres. When in doubt use a
supplied air breathing apparatus. The permitted minimum oxygen concentration of ambient air depends on
national regulations. When used in oxygen or an enriched-oxygen atmosphere, the increased potential hazard of
flammability has to be regarded.
The mask as part of a respiratory protective device ensures an appropriately tight fit of the user's face against the
ambient atmosphere.
It is imperative that this operating manual be read and observed when using the device. In particular, the safety
instructions, as well as the information for the use and operation of the device, must be carefully read and
observed. Furthermore, the national regulations applicable in the user's country must be taken into account for a
safe use.

2 Description
The face blank is made of a special soft rubber compound and assures a snug, comfortable fit and a tight seal.
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.
