Hazard statements

Irritating to respiratory system Harmful: danger of serious damage to health by prolonged exposure through inhalation

Precautionary statements

Do not breathe dust Emergency Overview: Not explosive, not a fire hazard

Principle Routes of Exposure

and Potential Health Effects Inhalation: Acute effects - Dust may cause irritation of the nose, throat, and airways, resulting in coughing and sneezing. Certain susceptible individuals may experience wheezing (spasms of the bronchial airways) on inhaling dust during sanding or sawing operations.

Potential chronic health

Repeated and prolonged overexposures to dust containing crystalline silica can cause silicosis (scarring of the lung) and increases the risk of bronchitis, tuberculosis, lung cancer, renal disease, and scleroderma (a disease affecting the connective tissue of the skin, joints, blood vessels, and internal organs). Some studies suggest that cigarette smoking increases the risk of silicosis, bronchitis and lung cancer in persons also exposed to crystalline silica. Acute silicosis - a sub-chronic disease associated with acute, massive silica exposure, is a rapidly progressive, incurable lung disease that is typically fatal. Symptoms include, but are not limited to, shortness of breath, cough, fever, weight loss and chest pain. Such exposure may cause pneumoconiosis and pulmonary fibrosis. Ingestion: Unlikely under normal conditions of use, but swallowing the dust from this product may result in - irritation or damage to the mouth and gastrointestinal tract due to alkalinity of dust.

Skin: Dust may cause irritation of the skin from friction but cannot be absorbed through intact skin.

Medical Conditions Generally Aggravated by Exposure

Pulmonary function may be reduced by inhalation of respirable crystalline silica and/or cellulose. If lung scarring occurs, such scarring could aggravate other lung conditions such as asthma, emphysema, pneumonia or restrictive lung diseases. Lung scarring from crystalline silica may also increase risks to pulmonary tuberculosis. Smoking: Some studies suggest that cigarette smoking increases the risk of occupational respiratory diseases, including silica-related respiratory diseases. Carcinogenicity: The International Agency for the Research on Cancer (IARC) has classified crystalline silica inhaled in the forms of quartz or cristobalite from occupational sources as carcinogenic to humans.
