2 Caution! May cause eye, skin, and respiratory tract irritation. Contains trace amounts of quartz which may lead to fibrotic lung disease, silicosis or cancer. Target Organs: Lungs. Potential Health Effects Eye: May cause eye irritation. Skin: Dust may cause mechanical irritation. Ingestion: May cause irritation of the digestive tract. Inhalation: May cause respiratory tract irritation. Chronic: Prolonged exposure to respirable crystalline quartz may cause delayed lung injury/fibrosis (silicosis). Section 4 - First Aid Measures Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.

3 Get medical aid. Skin: Get medical aid if irritation develops or persists. Wash clothing before reuse. Flush skin with plenty of soap and water. Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid. Get medical aid if irritation or symptoms occur. Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: No specific antidote exists.

4 Treat symptomatically and supportively. (1 of 5)7/23/2007 12:58:13 5 - Fire Fighting Measures General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing Media: Use extinguishing media most appropriate for the surrounding fire. Flash Point: Not applicable. Autoignition Temperature: Not applicable.

5 Explosion Limits, Lower:Not available. Upper: Not available. NFPA Rating: (estimated) Health: 1; Flammability: 0; Instability: 0 Section 6 - Accidental Release Measures General Information: Use proper personal protective equipment as indicated in Section 8. Spills/Leaks: Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation. Section 7 - Handling and Storage Handling: Wash thoroughly after handling.

6 Use with adequate ventilation. Minimize dust generation and accumulation. Avoid contact with skin and eyes. Avoid ingestion and inhalation. Storage: Store in a cool, dry, well-ventilated area away from incompatible substances. Section 8 - Exposure Controls, Personal Protection Engineering Controls: Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.
