APPLICATION / LIMITATION
If the polluted air’s oxygen content is 17-21% (volume), RSG HALF MASK can be used
with an RSG gas, RSG particle or RSG combined filter. Use an oxygen meter to
ascertain the oxygen content of the air. Only RSG filters are tested and approved for
use with the RSG HALF MASK. Follow the filter’s instructions for use carefully.
If the oxygen content of the air is less than 17% (volume), an air-supplied respirator
which is independent of the surrounding air must be used.
If the gas content of the air exceeds 0.1% (volume), or the air contains particularly
noxious particles or gases, a full face mask should be used (RSG FULL FACE MASK).
Note that eye and head protection may also be necessary.
In areas where the use of respiratory equipment is necessary, there is often a danger
of explosion. If this is the case, then the relevant precautions must be observed.
If the user has certain physical features (such as a beard or thick sideboards), then the
RSG HALF MASK might not give a satisfactorily tight fit to the face. This will also apply
if spectacle frames obstruct the facial seal. In such cases, the user carries the risk of
damage to his health.
Leave the area immediately, check the mask and replace parts if:
1. The mask, parts thereof, or filters are damaged.
2. Breathing difficulties occur.
3. Dizziness or indisposition occurs.
4. Pollution can be tasted or smelt, or other irritation occurs.
