1.2 Drawing and components list See the expanded drawing of the
BLS masks reported on last page. Component list: See Table1
1.3 Applications The full face masks of this series can be used in
conditions that require protection for both eyes and respiration. They
are particularly recommended for toxic and/or hazardous substances.
The full face mask BLS may be used with gas, particle and combined
filters. For a correct use and choice of the gas filters see the provided
instruction leaflet.
1.4 Selection of breathing protector equipped with filter To select
this kind of personal protective devices it is necessary to consider the
following indicators: NPF (nominal protection factor) is the value came
from the maximum percentage of total inward leakage allowed by the
relevant European standard (NPF = 100/ % maximum total inward
leakage admitted). APF (assigned protection factor) is the level of
respiratory protection that can realistically be expected to be achieved by
correctly fitted respirator (it is different for each State). TLV (threshold
limit value) is a concentration threshold - generally expressed in parts per
million, ppm – for the safety of the people exposed to dangerous
substances. The APF multiplied by the TLV of the substance gives the
concentration of pollutants to which an operator can be exposed wearing
a specific device. For the selection and maintenance of the filtering
devices and for the definition and use of APF and NPF also refers to the
European Standard EN 529 and to the relevant national regulations.
