Silica dust from cutting, grinding, and drilling concrete can cause irreversible lung disease—even at regulated exposure limits. Learn why disposable masks often fall short and how stronger respiratory protection programs reduce long-term risk. Protecting workers starts with understanding the hazard.

Cutting, grinding, drilling, and breaking concrete, brick, and stone generate respirable crystalline silica—microscopic particles small enough to penetrate deep into the lungs. According to the CDC and NIOSH, these particles can cause silicosis, lung cancer, COPD, and other serious diseases.

Once inhaled, silica dust can lead to:

• Silicosis (an incurable and sometimes fatal lung disease)
• Lung cancer (classified as a human carcinogen by IARC and NIOSH)
• Chronic obstructive pulmonary disease (COPD)
• Kidney disease and autoimmune disorders

What makes silica especially dangerous is that serious disease continues to occur at or even below many current exposure limits. OSHA notes that long-term exposure, even at regulated limits, can still pose significant health risks over a working lifetime.
