Hitachi RP 350YDM Handling Instructions Manual page 29

Precautionary measures with vacuum cleaners class H and M
The outside of the vacuum cleaner should be cleaned and wiped
down or should be treated with a sealing agent before being
removed from the dangerous area. All parts of the vacuum cleaner
must be considered to be contaminated when they are removed
from the danger area and suitable handling must be used to
prevent dust distribution.
Contaminated items
When carrying out maintenance or repair work, all contaminated
items which have not been adequately cleaned must be disposed
of. Such items must be disposed of in impermeable bags in ac-
cordance with the applicable regulations concerning the disposal
of such waste.
Testing the effectiveness of the vacuum cleaner
NOTE: In addition, the effectiveness of the vacuum cleaner class H
must be checked at least once a year.
There must be an adequate air exchange rate L in the room if the
exhaust air returns to the room. Further information can be taken
from your national regulations.
