This
image shows dust so deep on " I " beam flanges that it exceeds the
angle-of-repose and is constantly falling into the general environment. Cleaning of a
facility on a regular basis will prevent buildup of dust. Spills of silica containing
materials should be promptly cleaned up. Cleaning should employ methods which do not
create dust (e.g., vacuuming, wet washdown) rather than dust generating methods (e.g.,
sweeping, blowing). |
