Precautionary measures with vacuum cleaners class H and M
The outside of the vacuum cleaner should be cleaned by dust
extraction procedures and wiped down, or should be treated with a
sealing agent before being removed from the hazardous area. All
parts of the vacuum cleaner must be considered to be contamina-
ted when they are removed from the hazardous 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
accordance with the applicable regulations concerning the disposal
of such waste.
11.1 Testing the effectiveness of the vacuum
cleaner
At least once a year, the manufacturer or an instructed person must
perform a technical inspection including filters, air tightness of the
vacuum cleaner, and control mechanisms.
In addition, the effectiveness of the vacuum cleaners with dust
class H and H-asbestos must be checked at least once a year or
more frequently. The test method, which can be used for demonst-
rating the effectiveness of the device, is defined in EN 60335-2-69
AA.22.201.2. If the test is not passed, it must be repeated with a
new main filter.
There must be an adequate air exchange rate L in the room if the
exhaust air returns to the room. Observe national regulations.
If the suction power of the vacuum cleaner is reduced and the
cleaning of the filter cartridges is no longer sufficient (assuming that
tank is emptied and fleece filter bag is replaced), it is necessary to
replace the folded filter cartridges (see „8.1 Changing the folded
filter cartridges" auf Seite 9).
