U.S. SILICA COMPANY <br />Safety Data Sheet <br />Silica Sand or Ground Silica Page 2 of 9 <br />Date of preparation/revision: May 4, 2015 <br /> <br />3. COMPOSITION / INFORMATION ON INGREDIENTS <br /> <br />Component CAS No. Percent <br />Crystalline Silica (quartz) 14808-60-7 95-99.9 <br /> <br />4. FIRST-AID MEASURES <br /> <br />Inhalation: First aid is not generally required. If irritation develops from breathing dust, move the person from <br />the overexposure and seek medical attention if needed. <br />Skin contact: First aid is not required. <br />Eye contact: Wash immediately with plenty of water. Do not rub eyes. If irritation persists, seek medical <br />attention. <br />Ingestion: First aid is not required. <br />Most important symptoms/effects, acute and delayed: Particulates may cause abrasive eye injury. Inhalation <br />of dust may cause respiratory tract irritation. Symptoms of exposure may include cough, sore throat, nasal <br />congestion, sneezing, wheezing and shortness of breath. Prolonged inhalation of respirable crystalline silica <br />above certain concentrations may cause lung diseases, including silicosis and lung cancer. <br />Indication of immediate medical attention and special treatment, if necessary: Immediate medical attention <br />is not required. <br /> <br />5. FIRE-FIGHTING MEASURES <br /> <br />Suitable (and unsuitable) extinguishing media: Use extinguishing media appropriate for surrounding fire. <br /> <br />Specific hazards arising from the chemical: Product is not flammable, combustible or explosive. <br /> <br />Special protective equipment and precautions for fire-fighters: None required. <br /> <br />6. ACCIDENTAL RELEASE MEASURES <br /> <br />Personal precautions, protective equipment, and emergency procedures: Wear appropriate protective <br />clothing and respiratory protection (see Section 8). Avoid generating airborne dust during clean-up. <br /> <br />Environmental precautions: No specific precautions. Report releases to regulatory authorities if required by <br />local, state and federal regulations. <br /> <br />Methods and materials for containment and cleaning up: Avoid dry sweeping. Do not use compressed air to <br />clean spilled sand or ground silica. Use water spraying/flushing or ventilated or HEPA filtered vacuum cleaning <br />system, or wet before sweeping. Dispose of in closed containers. <br /> <br />7. HANDLING AND STORAGE <br /> <br />Precautions for safe handling: <br />Avoid generating dust. Do not breathe dust. Do not rely on your sight to determine if dust is in the air. <br />Respirable crystalline silica dust may be in the air without a visible dust cloud. Use adequate exhaust ventilation <br />and dust collection to reduce respirable crystalline silica dust levels to below the permissible exposure limit <br />(“PEL”). Maintain and test ventilation and dust collection equipment. Use all available work practices to control <br />dust exposures, such as water sprays. Practice good housekeeping. Do not permit dust to collect on walls, floors, <br />sills, ledges, machinery, or equipment. Keep airborne dust concentrations below permissible exposure limits.
