6 ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Avoid breathing dust or fume. Avoid contact with skin and eyes.
Methods and Materials for Containment and Cleaning Up: Avoid creating dust. Sweep or scoop up. Take care with items that are sharp. Place in an appropriate container for further handling and disposal.
Environmental Precautions: Do not allow to enter drains or to be released to the environment.
7 HANDLING AND STORAGE
Precautions for Safe Handling: Protect against physical damage. Wear cut-resistant gloves when handling breakable or sharp materials. Use protective glasses. Avoid creating dust. Avoid breathing dust or fumes. Provide adequate ventilation if dusts are created. Avoid contact with skin and eyes. See section 8 for information on personal protection equipment.
Conditions for Safe Storage: Store in a cool, dry, well-ventilated area. Store in a tightly sealed container. See section 10 for more information on incompatible materials.
8 EXPOSURE CONTROLS AND PERSONAL PROTECTION
Exposure Limits: OSHA/PEL: ACGIH/TLV:
Silicon Dioxide, amorphous No exposure limit established No exposure limit established
Quartz (respirable) 10 mg/m3 ---
Silica, crystalline (respirable) --- 0.025 mg/m3 (for α-quartz and crystobalite)
Engineering Controls: Ensure adequate ventilation to maintain exposures below occupational limits. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.
Individual Protection Measures, Such as Personal Protective Equipment:
Respiratory Protection: Avoid inhaling dusts. Use suitable respirator if dusts are present.
Eye Protection: Safety glasses
Skin Protection: Impermeable gloves, protective work clothing as necessary.

11 TOXICOLOGICAL INFORMATION
Likely Routes of Exposure: Inhalation, skin and eyes.
Symptoms of Exposure: May cause irritation if dusts or fumes are inhaled or swallowed. Dusts may irritate skin and eyes.
Acute and Chronic Effects: Silicon dioxide is chemically and biologically inert when ingested. Heavy exposure to freshly formed silica fume may cause an acute reaction similar to metal fume fever. Respirable quartz dust particles can be inhaled and deposited in the lung. Silicosis, lung cancer and pulmonary tuberculosis are associated with occupational exposure to quartz dust. There is sufficient evidence in humans for the carcinogenicity of inhaled crystalline silica in the form of quartz or cristobalite dusts from occupational sources. Because amorphous silica is less fibrogenic than crystalline silica, silicosis has rarely been observed after exposure to pure amorphous silica.
Acute Toxicity: No data
Carcinogenicity: (Note: the material as supplied is in solid form and may be crystalline or amorphous. Carcinogenicity is assigned to respirable dusts of crystalline silica only)
NTP: Silica, crystalline (respirable size): K - Known to be carcinogenic

16 OTHER INFORMATION
Silicosis is a lung disease caused by breathing in crystalline silica dust. Crystalline silica is a basic component of soil, sand, granite, and most other types of rock. Silicosis mostly affects workers exposed to silica dust in occupations such as mining, glass manufacturing, sand-blasting, and foundry work. Over time, inhalation of silica dust particles can cause inflammation, fluid buildup and scarring in the lungs. The symptoms of silicosis usually take many years to develop and include cough, weight loss, and fatigue. Silicosis can also increase the risk of other serious and potentially life-threatening conditions, including chronic obstructive pulmonary disease (COPD) and lung cancer. Even though the risks associated with crystalline silica (silicon dioxide) are mainly from long-term exposure to dusts in industrial settings, it seems prudent to take all precautions against breathing any silicon dioxide dusts.
