Hazard Statements: May cause mild irritation to eyes, skin, respiratory tract
Precautionary Statements: Avoid inhalation of dust, use appropriate protective gear if dust is generated, wash hands after handling
Potential Health Effects: Extended exposure could provoke nuisance dust symptoms such as coughing and sneezing
Carcinogenicity: Not listed as carcinogen by IARC, NTP, or OSHA
Chemical Name: Aluminum Hydroxide
Synonyms: Hydrated alumina, aluminum trihydroxide
Concentration: 99-100% purity for most industrial and laboratory grades
Impurities: Trace metals, silica in very low quantities as found in raw materials
Eye Contact: Flush eyes gently with running water for 15 minutes, remove contact lenses if worn, seek medical advice for redness or irritation
Skin Contact: Wash area with mild soap and lot of water, remove contaminated clothing, consult physician if irritation continues
Inhalation: Move person to fresh air, encourage breathing, seek support for persistent coughing, consult professional if symptoms persist
Ingestion: Rinse mouth with water, seek advice for large accidental intake, do not induce vomiting without instruction from medical staff
Fire Hazards: Non-flammable material, does not support combustion
Suitable Extinguishing Media: Use water spray, foam, CO₂, dry powder as needed for surrounding fire
Special Protective Equipment: Firefighters should choose suitable gear for adjacent burning materials, breathing apparatus when smoke is heavy
Explosion Hazards: No unusual hazard from normal storage and handling
Decomposition Products: At high temperatures can release water vapor, aluminum oxide which may aggravate surrounding fire
Personal Precautions: Wear dust mask, goggles, and gloves to reduce risk of contact
Environmental Precautions: Prevent bulk waste from entering water courses or sewers, sweep up dry spills and collect for safe disposal
Cleanup Methods: For dry material, sweep or vacuum up using non-sparking tools, keep dust at minimum, clean surface with wet cloth for residual dust
Waste Disposal: Transfer recovered product to labeled container for proper disposal
Safe Handling: Work in well-ventilated area, use local exhaust when generating dust, avoid breathing dust and direct skin or eye contact
Storage Conditions: Keep containers tightly closed, store in dry, cool, well-ventilated environment, prevent moisture ingress, avoid incompatible materials like acids
Incompatible Materials: Acids, strong bases, ammonium salts can chemically react with product
Hygiene Measures: Wash hands and face after use, avoid eating or drinking during handling
Occupational Exposure Limits: ACGIH TLV for nuisance particulates is 10 mg/m³ (total dust), 3 mg/m³ (respirable fraction)
Engineering Controls: Use local exhaust or general room ventilation as needed to control dust
Personal Protective Equipment: Dust mask for airborne particles, safety goggles for eye protection, gloves for skin protection, lab coat or coveralls
Hand Protection: Chemical-resistant gloves, especially nitrile or rubber
Eye Protection: Tight-fitting goggles or face shield in high-dust conditions
Respiratory Protection: NIOSH-approved particulate respirator if air concentrations exceed safe limits
Appearance: Fine white powder, odorless
Molecular Weight: 78.00 g/mol
Melting Point: Decomposes at 300°C
Boiling Point: Not applicable—decomposes before boiling
Density: 2.42 g/cm³
Solubility in Water: Insoluble
pH (as suspension): Approximately 8 to 9 at 20°C
Evaporation Rate: Not applicable
Vapor Pressure: Not applicable
Flash Point: Not flammable
Chemical Stability: Stable at room temperature and pressure, resists decomposition under normal conditions
Hazardous Reactions: May react with strong acids forming aluminum salts and hydrogen gas, interaction with strong bases and ammonium salts creates heat or toxic gases
Conditions to Avoid: Excess heat, exposure to acid fumes, humidity for long storage
Hazardous Decomposition Products: At elevated temperatures generates aluminum oxide and water vapor
Polymerization: Does not undergo hazardous polymerization
Acute Toxicity: Low toxicity, oral LD50 in rats greater than 5000 mg/kg
Inhalation Effects: Nuisance dust, may provoke coughing, throat or nasal irritation
Skin Effects: Prolonged or repeated exposure may cause mild irritation or dryness
Eye Effects: Dust causes mild, temporary irritation
Chronic Effects: Long-term occupational exposure to high dust concentrations linked with mild respiratory symptoms, not associated with systemic toxicity
Carcinogenicity: No evidence for carcinogenic effects in humans
Environmental Fate: Product is stable, inert, does not biodegrade or bioaccumulate
Aquatic Toxicity: Low risk for acute toxicity to aquatic life at usual concentrations
Soil Mobility: Tends to remain in particle form, limited migration in soil and water
Persistence and Degradability: Not readily degradable, expected to settle out from water column
Bioaccumulative Potential: Unlikely to bioaccumulate, low log Kow value
Safe Disposal: Dispose of through licensed waste handler, in accordance with local, regional, and national regulations
Waste Treatment Methods: For small quantities, landfill disposal in sealed container; for bulk, consider recycling options where available
Special Considerations: Do not dispose into surface water, sewers, or unrestricted landfilling without approval
Container Cleanup: Triple rinse empty containers, follow up with recycled use or disposal to authorized landfill
