Concrete
grinding dust can cause silicosis, an
incurable disease of the lungs
"Silicosis (also
known as Grinder's disease and Potter's
rot) is a form of occupational lung
disease caused by inhalation of
crystalline
silica dust..."Wikipedia
The most common
ways airborne concrete dust is produced
while grinding are:
1. Dry
grinding or cutting without a dust collection system
2. Leaky
dust shrouds caused by - poor shroud
design, or worn and torn dust shroud
seals, or incorrectly
adjusted dust shroud seals
4. Low
airflow dust
collection systems that are
either too small or have blocked filters
5. Not
containing dust in a bag for disposal
and open
air emptying of dust collection
containers
6. Open
air cleaning of dust collector filters
7.
Sweeping dusty floors
Always use
the best dust shrouds available, check
your vacuum filters every 5-10 mins with
small dust collectors and whenever any
dust begins to escape from the grinding
process. Use an adequately sized dust
collector for the seal area of your
shroud.

11/2 inches or 35mm
Never
sweep bare or ground concrete floors,
instead use a vacuum to pick up dust and
debris. Fit a plastic bag to your dust
collector base where possible or empty
the base into a plastic bag so that the
bag can be sealed for clean disposal
without airborne dust.
Use a dust
collector with self cleaning filters to
avoid shaking filters in the open air to
clean them. Compressed air should never
be used to clean concrete dust from
filters.

Quality dust shrouds are essential to help
prevent
silicosis

Steel dust shroud
with semi-sealed edging feature
The
steel constructed
Hoverhood and
Cornerhood dust shrouds for angle
grinders have many features not found in
other shrouds that prevent concrete dust
from escaping while grinding. They are
specifically designed for the purpose
and do not require a high-powered dust
collector for them to perform properly.
