What health concern is associated with exposure during drilling in concrete?

The health concern associated with exposure during drilling in concrete is silica. When concrete is drilled, it generates fine particles of silica, specifically crystalline silica. Inhalation of these particles can lead to serious respiratory issues, including silicosis, a chronic lung disease that arises from the inflammation and scarring of lung tissue due to the inhalation of silica dust over time. Prolonged exposure can also increase the risk for other respiratory diseases, including lung cancer and chronic obstructive pulmonary disease (COPD).

Understanding the hazards associated with silica exposure is crucial for implementing the necessary safety measures in construction and renovation activities. These typically include wearing appropriate personal protective equipment (PPE), such as respirators, and using water suppression or local exhaust ventilation techniques to minimize airborne dust.
