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 removed from the danger ar-
ea. All unit parts are to be considered
contaminated when they are removed
from the danger area.
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.

must be serviced and maintained regularly.
This means that the manufacturer's staff or
persons trained by the manufacturer must
check the equipment for proper functioning
at least once a year, i.e. check for leaks, fil-
ter damage, functioning of the controlling
elements, etc.
