NIOSH Survey Reports
NIOSH conducts engineering evaluation studies of worksites with silica dust and/or other occupational hazards as a part of control technology research. The field study portion of this research is documented in workplace survey reports available on the NIOSH Engineering Controls Topic Page.
NIOSH Health Hazard Evaluations
A NIOSH Health Hazard Evaluation (HHE) is a study of a workplace to learn whether workers are exposed to hazardous materials or harmful conditions, such as exposure to crystalline silica dust. The NIOSH Health Hazard Evaluations site has a searchable database of HHE reports, including silica-related HHEs, and instructions for requesting an HHE.

NEW Reducing Hazardous Dust Exposure When Rock Drilling During Construction
DHHS (NIOSH) Publication No. 2009-124 (April 2009)
Construction workers may be exposed to hazardous dust containing crystalline silica during site preparation when drilling systems are used. The National Institute for Occupational Safety and Health (NIOSH) found that drill dust could be decreased by using wet or dry dust reduction engineering controls, enclosed cabs, and implementing a dust control program.
NEW Reducing Hazardous Dust in Enclosed Operator Cabs During Construction

Construction workers may be exposed to hazardous dust containing silica when working in enclosed cabs during construction activities. The National Institute for Occupational Safety and Health (NIOSH) found that equipment operator exposure could be reduced by retrofitting air pressurization and filtration systems on existing cabs, using sweeping compounds on soiled floors, and implementing a dust control program.
NEW Control of Hazardous Dust When Grinding Concrete
DHHS (NIOSH) Publication No. 2009-115 (April 2009)
Construction workers are exposed to hazardous dust when using handheld electric grinders to smooth poured concrete surfaces after forms are stripped. The National Institute for Occupational Safety and Health (NIOSH) found that exposures could be reduced if a local exhaust ventilation (LEV) shroud was attached to the grinder.
Control of Hazardous Dust During Tuckpointing
DHHS (NIOSH) Publication No. 2008-126 (September 2008)

Construction workers are exposed to hazardous dust when grinding or cutting mortar or cement from between the bricks of old buildings. The National Institute for Occupational Safety and Health (NIOSH) found that exposures could be reduced using tool-mounted local exhaust ventilation and work practices.
Workplace Solutions: Water Spray Control of Hazardous Dust When Breaking Concrete with a Jackhammer
DHHS (NIOSH) Publication No. 2008-127 (May 2008)
En Español
Construction workers are exposed to hazardous dust when using jackhammers to break concrete pavement. NIOSH found that exposures could be reduced by using a water-spray attachment. A study to measure exposures found that jackhammer operators who break concrete were exposed to about 6 times the NIOSH recommended exposure limit (REL).
Silicosis - Working with Cement Roofing Tiles: A Silica Hazard
DHHS (NIOSH) Publication No. 2006-110 (2006)
En
Español
Although respirable silica is a recognized health hazard in the construction industry, only recently has this exposure been documented in roofers. NIOSH has measured respirable silica levels up to four times the recommended exposure limit around roofers cutting cement products such as when roofing tiles are cut during the installation process.

DHHS (NIOSH) Publication No. 98-150 (1998)
En
Español
On surface coal mining and construction sites, blast hole drills are notorious
sources of airborne respirable dust that may contain significant amounts
of silica. This Hazard Control offers information on a unique circular
deck shroud which may reduce dust up to 99%.
