Related symptoms:
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 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.
The following relates to health effects of cellulose: Based on limited animal
research, it is possible that repeated chronic inhalation exposure to
cellulose fiber dust over time may lead to inflammation and scarring of the
lung in humans. Precautions taken for crystalline silica dust will protect
against cellulose.
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.
Acute and chronic effects:
 Acute toxicity – not classified
 Skin corrosion / irritation – not classified
 Serious eye damage / irritation – not classified
 Respiratory or skin sensitization – not classified
 Germ cell mutagenicity – not classified
 Carcinogenity – may cause cancer if dust from product is inhaled
 Specific target organ toxicity (repeated exposure) – causes damage
to lungs and respiratory system through prolonged or repeated
inhalation of dust from product
Carcinogenity:
California Proposition 65 Warning:
