Application Conditions
Filtering devices must not be used in confined spaces (containers, canals, pits, etc.).
For some applications, an additional protection for eyes and body should be considered.
After and before use, check the half mask and filters and if necessary, clean, disinfect and use new filters. Always use
only a complete and undamaged respiratory protective device. The user of a filtering device must be qualified and
trained in its use. The selected filter and proper face piece must be in faultless condition and suitable for the intended
application.
Additional Information for Australian and New Zealand Users:
Users should review AS/NZS 1715 for guidance regarding selection, use and maintenance of
respiratory products. Per AS/NZS 1716 Class 1 and Class 2 A, B, E and K filters fitted to a full face
piece provide a protection factor of up to 50 and 100 times the recommended exposure limit for the
contaminant respectively. Class 1 and Class 2 gas or combination filters have a maximum gas vapour
concentration of 1000 and 5000 ppm respectively.
Note that the efficiency of the particulate filter deteriorates in the presence of substances, such as oil
mists, commonly encountered in the workplace.
Open Flames, Metal Droplets
The use of filtering devices, during work with open flames and metal droplets (e.g. welding), may cause serious risk
due to ignition of the filter media, which may generate acute levels of toxic substances.
2 Use
Applicable National Regulations must be observed (BGR 190). For guidance the EN529:2005 (Recommendations
for selection, use, care and maintenance) is available.
When selecting the filter, it may be necessary to pay attention to highly toxic substances and high concentrations.
2.1 Respiratory Protective Device
WARNING!
Before use, check the half mask and if necessary, clean, disinfect and use new filters. Always use a complete and
undamaged respiratory filtering device.
Failure to follow this warning can result in serious personal injury or death.
Donning the Half Mask
1. Place neck strap over the head to the nape of the neck.
2. Place half mask over chin and nose.
3. Place cradle head straps over head (see Figure 2 ).
4. Pull harness evenly tight on both sides for a comfortable, correct fit (see Figure 3 ).
5. Loosen the straps by pulling the tab back on the latch with your finger (see Figure 4 ).
Tightness Test
In order to check the facepiece-to-face tightness a leak test must be performed before each use.
WARNING!
If any leakage is detected, correct before using the respiratory filtering device. For persons with beards, long
sideburns or scars passing under the seal it is unlikely that a tight fit can be achieved.
Failure to follow this warning can result in serious personal injury or death.
