Superabrasive Lavina OSHA Compliance Manual

Concrete grinding creates a lot of dust which could be hazardous. OSHA has released its fi nal
ruling on crystalline silica exposure which becomes e ective on Sept 23, 2017, and contractors are
required to take measures to control silica dust exposure.
To conform the new regulations, contractors should use one of the following work methods
when grinding concrete:
• Grinding wet, i.e. using water to minimize airborn dust.
All Lavina grinders are equipped with integrated water
delivery system that continuously feeds water to the
grinding surface.
• Grinding dry and using dust collection systems. Make
sure the dust extractor is appropriate for the grinder
you are using - see our reference grinder-vac guide
on next page. Lavina X dust extractors are equipped
with air fi lters with large surface area and Hepa fi lter(s)
with e ciency of 99.99% at 0.3 microns, and have a
fi lter-cleaning mechanism. All models except V20-X
have completely automatic Jet Pulse fi lter cleaning,
and the V20-X has manual fi lter cleaning mechanism.
Furthermore, Lavina dust extractors feature the
Longopac continuous bagging system for easier and
safer dust disposal.
• Using protective masks or respirators which are ap-
proved for use with silica dust and conform government
regulations.
