– 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 cleaning or repair of the vacuum
cleaner after a period of inactivity, one
must expect a friction-sensitive, explo-
sive-containing crust. This crust must
first be removed with moisture.
