Device with combined filter
The specified multiples of threshold value for the gas or particle
filters are given separately, but in all cases the lowest value applies
*) Provided that the maximum permissible detrimental gas concentration for the gas filter is not exceeded.
For non-powered filtering devices with gas filter, concentration must not exceed 0.1 vol.% in gas filter
class 1 and 0.5 vol.% in gas filter class 2 and 1.0 vol.% in gas filter class 3.
**) If national guidelines exist: in all cases the lowest value applies.

4. Preparations for use, and Donning
See Instructions for Use of the filter and blower device to be used.
Check before use
intactness of facepiece, rubber parts and visor
head harness condition and elasticity
that speech diaphragm is in place
that exhalation valve is in place and that its cover is properly fastened
that inh. and exh. valves function properly
that the filter is correct for the intended use. Filter type and class are evident from the
marking.
that storage period of the filter has not been exceeded
filter condition and intactness. Shake the filter to ensure that there are no loose
components/contents. The filter shall be replaced if it has been exposed to excessive force
or impact. It may be damaged.
With a blower device
Check adequate air flow (see Instructions for Use of the blower unit).
