Precautionary measures
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 contaminat-
ed 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.
12.1 Testing the effectiveness of the vacuum
cleaner
