Dust extracting machines are safeguards
for the prevention or elimination of hazards
defined in the regulations of BGV A1.
– In order to carry out maintenance work,
the user must disassemble, clean and
service the unit, in so far as this is pos-
sible without endangering maintenance
personnel and other persons. Suitable
precautions include decontamination
before the unit is disassembled. Pre-
cautions must be taken for local filtered
forced air ventilation at the place where
the unit is disassembled, the cleaning of
the maintenance surface and suitable
protection of the personnel.
– The outside of the unit should be cleaned
thoroughly and any harmful substances
removed. Alternatively, a sealed coating
may be applied before the unit is re-
moved from the danger area. All unit
parts are to be considered contaminated
when they are removed from the danger
area. To avoid distribution of the dust,
you must take the appropriate measures.
– In the framework of maintenance and
repair work all contaminated objects
that cannot be cleaned satisfactorily
must be disposed of. Such objects must
be disposed of in impermeable bags in
accordance with the valid provisions for
the disposal of such waste.
– During the transport and maintenance
of the appliance the extraction opening
is to be closed with the connection
socket.
