Video: Controlling Respirable Silica Exposure in Construction

Respirable crystalline silica - very small particles at least 100 times
smaller than ordinary sand you might find on beaches and playgrounds - is created
when cutting, sawing, grinding, drilling, and crushing stone, rock, concrete,
brick, block, and mortar.

Workers who inhale these very small crystalline silica particles are at
increased risk of developing serious silica-related diseases, including:
- Silicosis, an incurable lung disease that can lead to disability and death;
- Lung cancer;
- Chronic obstructive pulmonary disease (COPD); and
- Kidney disease.

The U.S. Department of Labor's Occupational Safety and Health Administration
(OSHA) has published a video earlier this year focusing on handheld power saws,
showing how an integrated water delivery system controls silica dust created
when cutting certain materials.
