| Handling and Storage | Back to Contents | 【Storage】
Store in a dry area. | 【Handling】
Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Avoid ingestion and inhalation. |
| Hazards Identification | Back to Contents | 【Inhalation】
Dust is irritating to the respiratory tract. May cause lung damage. Contains crystalline silica which may lead to respiratory abnormalities and silicosis. | 【Skin】
Dust may cause mechanical irritation. | 【Eyes】
Dust may cause mechanical irritation. | 【Ingestion】
May cause irritation of the digestive tract. |
| Exposure Controls/Personal Protection | Back to Contents | 【Personal Protection】
Eyes: Wear safety goggles approved for the handling of explosive materials. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. | 【Respirators】
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. | 【Exposure Effects】
Chronic inhalation of dust may lead to silicosis. May cause lung damage. May cause silicosis-disabling pulmonary fibrosis characterized by fibrotic changes and miliary nodules in the lungs, dry cough, shortness of breath, emphysema, decreased chest expansion and increased susceptibility to tuberculosis. | 【Exposure limit(s)】
TLV: 10 mg/m3 (as TWA) (ACGIH 1992-1993) OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp) NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp) | 【Poison Class】

| Fire Fighting Measures | Back to Contents | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Material will not burn. Use extinguishing media appropriate to the surrounding fire. Dousing metallic fires with water may generate hydrogen gas, an extremely dangerous explosion hazard. Extinguishing media: Substance is noncombustible; use agent most appropriate to extinguish surrounding fire. | 【Fire Potential】
Noncombustible |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. |
