Understanding Silica Risks

Crystalline silica is found in many construction materials, including concrete, brick, mortar, and stone. When these materials are cut, ground, or drilled, fine silica dust can be released and inhaled—causing long-term respiratory damage if not properly controlled.

Health Hazards of Silica

• Silicosis: A lung disease caused by inhaling silica dust.
• Lung Cancer: Long-term exposure increases cancer risk.
• Chronic Obstructive Pulmonary Disease (COPD): Includes chronic bronchitis and emphysema.
• Kidney Disease: Evidence links silica to kidney damage in some cases.

Exposure Prevention Measures

• Use wet methods to suppress dust during cutting or grinding.
• Use local exhaust ventilation systems (LEVs) when available.
• Wear NIOSH-approved respirators if engineering controls aren’t enough.
• Enclose or isolate high-dust areas when possible.
• Clean surfaces with wet methods or HEPA-filter vacuums—never dry sweep.

Worker Responsibilities

• Attend training on silica safety and health effects.
• Use provided PPE and dust controls properly at all times.
• Report damaged equipment or dust control failures immediately.
• Practice good hygiene—wash hands and face before eating or drinking.
