Materials to avoid: • Reacts violently with : Strong acids Strong bases Sulphur compounds Reducing agents Oxidizing agents Heavy metals Amines Rust Conditions / hazards to avoid: See HANDLING AND STORAGE section of this MSDS for specified conditions. SADT - Self Accelerating Decomposition Temperature. Lowest temperature at which the tested package size will undergo a self-accelerating decomposition reaction. This reaction will generate flammable vapors which may autoignite. The length of time to generate a decomposition reaction, after the SADT has been reached or exceeded, is dependent upon how much the SADT has been exceeded and the length of time needed for the reaction exotherm (heat spike from increasing decomposition rate) to initiate a rapid decomposition reaction. Typically, SADT is inversely proportional to package size. Larger packages will have a lower SADT due to smaller ratio to heat transfer area to volume of product. Hazardous decomposition products: Thermal decomposition yields flammable and toxic products: Aromatic derivatives Carbon oxides 11.

Section 3 – Hazards Identification

Emergency Overview: High airborne levels of dust may cause irritation to eyes and upper respiratory tract.

Acute Health Effects: Inhalation: Excessive exposure to high concentrations of dust may cause irritation to the eyes, skin, and mucous membranes of the upper respiratory tract. Eye: Dusts may cause irritation to the eye. Scratching of cornea can occur if eye is rubbed. Ingestion: Ingestion of harmful amounts of this product as distributed is unlikely due to its solid insoluble form. Ingestion of excessive amounts of dust may cause nausea and vomiting. Chronic Health Effects: Chronic inhalation of respirable crystalline silica may cause silicosis; a fibrosis (scarring) of the lungs. Silicosis may be progressive; it may lead to disability and death. Crystalline silica inhaled from occupational sources is classified as carcinogenic to humans.

Section 4 – First Aid Measures Inhalation: If there is a gross inhalation of crystalline silica, remove the person immediately to fresh air. Consult a physician if necessary. Ingestion: Ingestion may cause gastrointestinal discomfort. Dilute by drinking large quantities of water. If discomfort persists, consult a physician. Eye Contact: Wash eyes with large amounts of water. If irritation persists, consult a physician. Skin Contact: Wash with soap and water. If irritation persists, consult a physician.

Section 10 - Stability and Reactivity

Stability: Stable under normal handling and storage conditions.

Hazardous Polymerization: Cannot occur.

Chemical Incompatibility (Materials to Avoid): Contact with powerful oxidizing agents such as fluorine, chlorine, triflouride, manganese trioxide, oxygen diflouride, may cause fires.

Hazardous Decomposition Products: Crystalline silica will dissolve in hydrofluoric acid and produce a corrosive gas (silicon tetraflouride).

Section 11 - Toxicological Information

Silicosis: The major concern is silicosis, caused by the inhalation and retention of respirable crystalline silica dust. Silicosis can exist in several forms, chronic (or ordinary), accelerated, or acute.

Chronic or Ordinary Silicosis (often referred to as Simple Silicosis) is the most common form of silicosis, and can occur after many years of exposure to relatively low concentrations of airborne respirable crystalline silica dust.

Accelerated Silicosis can occur with exposure to high concentrations of respirable crystalline silica over a shorter period.

Acute Silicosis can occur with exposures to very high concentrations of respirable crystalline silica over a very short period, sometimes as short as a few months. The symptoms of acute silicosis include progressive shortness of breath, fever, cough, weight loss. Acute silicosis can be fatal.

Carcinogen: IARC - Yes NTP - Yes OSHA - No

Autoimmune Diseases: Several studies have reported cases of several autoimmune disorders such as scleroderma, systemic lupus, and rheumatoid arthritis among silica exposed workers.

Tuberculosis: Individuals with silicosis are at increased risk to develop pulmonary tuberculosis, if exposed to persons with tuberculosis.

Kidney Disease: Several studies have reported excess cases of kidney diseases, including end stage renal disease, among silica-exposed workers.

Section 12 - Ecological Information

Crystalline Silica is not known to be ecotoxic, i.e., there are no data that suggests that crystalline silica is toxic to birds, fish, invertebrates, microorganisms or plants.
