Section 3 - Hazards Identification œœœœœ Emergency Overview œœœœœ Potential Health Effects Primary Entry Routes: Inhalation, Eye, and Ingestion. Acute Effects Inhalation: Inhalation of high concentrations of this inert nuisance particulate can result in mild irritation of the respiratory tract. Eye: May cause irritation through mechanical abrasion. Skin: May cause irritation through mechanical abrasion. Ingestion: Unlikely. Carcinogenicity: IARC, NTP, and OSHA do not list alumina trihydrate as a carcinogen. Medical Conditions Aggravated by Long-Term Exposure: n/a Chronic Effects: n/a Section 4 - First Aid Measures Inhalation: If overcome by high dust concentrations, remove to a ventilated area. Eye Contact: Flush eyes thoroughly for 15 minutes taking care to rinse under eyelids. Do not scrub. Abrasion may cause irritation. If discomfort continues, continue to wash with water. If irritation persists, consult a physician. Skin Contact: Wash skin thoroughly with soap and water for at least 15 minutes. Consult a physician if irritation persists. Ingestion: If swallowed, dilute with large amounts of water. Do not induce vomiting. Consult a physician immediately. After first aid, get appropriate in-plant, paramedic, or community medical support. Note to Physicians: n/a Special Precautions/Procedures: n/a Section 5 - Fire-Fighting Measures Flash Point: None known. Flash Point Method: n/a Burning Rate: Does not burn. Auto-ignition Temperature: Does not ignite. Flammability Classification: n/a Extinguishing Media: Water spray, carbon dioxide, or other dry chemical. Unusual Fire or Explosion Hazards: None known. HMIS H F R 1 0 0 PPE† E †Sec. 8 Revision date 10/22/07 Alumina Trihydrate MSDS No. 9605.33 Page 2 of 4 Hazardous Combustion Products: None. Fire-Fighting Instructions: Do not release runoff from fire control methods to sewers or waterways. Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus (SCBA) with a full face-piece operated in pressure-demand or positive-pressure mode. Section 6 - Accidental Release Measures Spill /Leak Procedures: Collect solids. Recycle if possible. Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120). Section 7 - Handling and Storage Handling Precautions: Avoid generating dust during handling. Storage Requirements: Keep material dry. Section 8 - Exposure Controls / Personal Protection Engineering Controls: Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at its source. Administrative Controls: Protective Clothing/Equipment: Wear tightly fitting safety goggles or safety glasses with side shields. Contaminated Equipment: Separate contaminated work clothes from street clothes. Launder before reuse. Remove this material from your shoes and clean personal protective equipment. Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics. Section 9 - Physical and Chemical Properties Physical State: white powder Appearance and Odor: white odorless powder Odor Threshold: n/e Vapor Pressure: n/e Vapor Density (Air=1): n/a Formula Weight: n/a Density: 8-80lb/ft3 Specific Gravity (H2O=1, at 4 °C): 2.4 pH: 8.5-10.2 (20% solution) Water Solubility: Insoluble Other Solubilities: Soluble in alkaline aqueous solutions or in HCL, H2SO4, and other strong acids in the presence of some water. Boiling Point: n/a Freezing/Melting Point: 3700F (2038C) Viscosity: n/a Refractive Index: n/a Surface Tension: n/a % Volatile: n/a Evaporation Rate: n/a Section 10 - Stability and Reactivity Stability: Alumina trihydrate is stable at room temperature in closed containers under normal storage and handling conditions. Polymerization: Hazardous polymerization cannot occur. Chemical Incompatibilities: Strong acids and bases. Alumina trihydrate reacts vigorously with strong acids and will dissolve in caustic solutions. Reactivity with Heat: When exposed to fire or heat, hydrated alumina loses its water of crystallization beginning at 392F (200C). Hazardous Decomposition Products: n/a Revision date 10/22/07 Alumina Trihydrate MSDS No. 9605.33 Page 3 of 4 Section 11- Toxicological Information Toxicity Data:* Eye Effects: Nuisance dust. May cause irritation through mechanical abrasion. Flush with water for at least 15 minutes. Consult physician if irritation is persistent. Skin Effects: Nuisance dust. May cause irritation through mechanical abrasion. Wash skin thoroughly with soap and water. Acute Inhalation Effects: Nuisance dust. Overexposure to dust may cause irritation to the respiratory tract. Should this occur, remove affected individual to fresh air. If symptoms persist, consult a physician. Acute Oral Effects: None known. Chronic Effects: None known. Carcinogenicity: Neither this product nor any of its components are considered carcinogenic by OSHA, IARC, NTP, or ACGIH.
