Hylea
Crystalline Silica High Risk
A mineral found in stone, sand, and quartz that becomes hazardous when cut, ground, or disturbed to create respirable dust. A major concern during countertop fabrication, concrete cutting, and sandblasting.
Health Concerns
- Causes silicosis - an incurable, progressive lung disease
- Classified as a known human carcinogen (lung cancer)
- Chronic bronchitis and other respiratory diseases
- Kidney disease associations
- Autoimmune disorders including scleroderma
- Tuberculosis risk increases with silicosis
Environmental Impact
- Dust can spread beyond work areas affecting nearby communities
- Mining and quarrying operations impact local environments
- Processing creates airborne particulates
Regulatory Status
OSHA has strict permissible exposure limits. Requires engineering controls and respiratory protection in workplaces. Some jurisdictions banning dry cutting of engineered stone.
What to Avoid
Dry cutting or grinding of stone, quartz, or concrete. Sand-based infill in artificial turf. Uncontrolled demolition of masonry.
Safer Alternatives
Wet cutting methods with dust suppression, porcelain or solid surface countertops, pre-fabricated stone pieces, alternative infill materials
