considered contaminated when they are removed
from the hazardous zone and appropriate actions
must be taken to prevent the dispersion of dust.

carried out, all the contaminated elements that
cannot be properly cleaned, must be eliminated.

complete filter system in place.
Use only genuine spare parts supplied and
authorized by the manufacturer.
