The product contains silica particles that may be broken down to the respirable size range during shipping, handling, or use and thus may be inhaled. This product contains crystalline silica. Prolonged or repeated inhalation of respirable silica from this product can cause silicosis. Skin contact: Causes skin irritation. Handling can cause dry skin, discomfort, irritation, and dermatitis. Acute silicosis, also called silicoproteinosis, develops after 1-3 years of exposure and progresses faster than accelerated silicosis. There is a rapid loss of pulmonary function, invariably followed by death. If the external temperature is high, it will lead to early dry shrinkage. Hence, it is more prone to cracks which may ultimately affect the overall strength. Construction with silica fume concrete is difficult, as the workability of silica fume concrete is poor.

Fly ash may pose an inhalation hazard when dry. Dry fly ash can cause respiratory irritation similar to flu-like symptoms. Bottom ash is a heavier, coarse material captured at the bottom of the coal furnace. Bottom ash can contain cresol and semivolatile organic compounds such as polycyclic aromatic hydrocarbons. Very small dust particles are created when workers cut, grind, drill, or crush materials that contain crystalline silica. These tiny particles ("respirable" particles) can travel deep into workers' lungs and cause silicosis, an incurable and sometimes deadly lung disease.
