Product Name: Sodium Aluminate
Chemical Formula: NaAlO2 or Na2O·Al2O3
Form: White to off-white solid, hygroscopic
CAS Number: 1302-42-7
Relevant Use: Water treatment, paper industry, construction, catalysts
Acute Hazards: Strongly alkaline and corrosive to skin, eyes, and mucous membranes, generates significant heat on contact with moisture
Main Risks: Severe eye damage, respiratory irritation, burns to skin, potential for environmental harm in aquatic locations
Signal Words: Danger; Corrosive; Irritant
Inhalation Risks: Dust may cause lung irritation, coughing, shortness of breath
Chronic Issues: Prolonged skin exposure can result in dermatitis or ulceration
Ingredient: Sodium Aluminate, typically 95% or more by weight
Impurities: Minimal, usually trace amounts of sodium hydroxide and aluminum hydroxide, depending on manufacturer and process
Physical Nature: Crystalline or granular solid, solubility in water yields highly alkaline solution
Inhalation: Move to fresh air, seek medical attention if symptoms develop; breathing dust leads to coughing, throat irritation
Skin Contact: Immediate and thorough rinsing with water, removal of contaminated clothing, seek medical help for persistent pain or burns
Eye Contact: Flush eyes with plenty of running water for 15+ minutes while holding eyelids open, seek medical attention promptly
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical attention promptly, risk of chemical burns to gastrointestinal tract
Flammability: Non-flammable
Extinguishing Media: Use standard agents for surrounding fire: foam, dry chemical, CO2, water spray
Hazardous Decomposition: Reacts with water or acids to release heat, can generate caustic aerosols
Firefighter Protection: Full protective gear including eye protection and self-contained breathing apparatus to guard against dust and caustic mist
Personal Protection: Wear chemical-resistant gloves, goggles, long sleeves, dust mask or respirator during cleanup
Spill Handling: Avoid generating dust, sweep up solid, place in leak-proof container
Containment: Prevent spillage from entering water bodies or sewer systems, rinse area thoroughly with large volumes of water after removal
Environmental Protection: Sodium aluminate’s high pH damages aquatic environments, prevent runoff
Handling Practices: Avoid breathing dust, minimize dust creation, use only in well-ventilated environments
Skin and Eye Safety: Always use personal protective equipment, keep eyewash station easily accessible
Storage Conditions: Keep container tightly closed, store away from acids, moisture, and incompatible chemicals, humidity causes clumping and heat generation
Incompatibilities: Keep away from strong acids, ammonium salts, certain metals (e.g. aluminum) due to violent reactions
Engineering Controls: Local exhaust, process enclosure, avoid open handling if possible
Threshold Limit Values (TLVs): No specific regulatory exposure limits for sodium aluminate dust, but workplace exposure should be kept as low as practical due to caustic nature
Personal Protective Equipment (PPE): goggles or face shield, impervious gloves, long sleeves, dust respirator if above nuisance levels
Hygiene: Wash hands and skin thoroughly after handling, do not eat, drink or smoke while handling
Appearance: White to off-white, powder or granular solid
Odor: Odorless
pH (1% solution): Highly alkaline (pH 11.5–13)
Melting Point: Decomposes before melting, decomposition at high temperatures
Solubility: Moderately soluble in water, extremely alkaline solution
Vapor Pressure: Not applicable (non-volatile solid)
Density: 1.5 – 1.6 g/cm³ (approximate)
Other Data: Hygroscopic, exothermic reaction on dissolving, dust may be irritating
Chemical Stability: Stable during normal storage and handling if kept dry
Reactivity: Reacts with acids to release heat and forms aluminum hydroxide, contact with water produces caustic solution and heat
Hazardous Decomposition: Prolonged exposure to humidity increases risk of container bursting
Incompatible Materials: Avoid acids, ammonium compounds, organic materials, moisture-sensitive compounds
Acute Toxicity: Not acutely toxic via ingestion in small quantities, major hazards from corrosive burns
Routes of Exposure: Inhalation, skin, eyes, ingestion
Symptoms: Strong irritation or burns, pain, redness, swelling; eye exposure can cause blindness
Chronic Effects: Dermatitis, prolonged respiratory irritation for those exposed without protection
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, or OSHA
Mutagenicity and Reproductive Toxicity: Not established, but no current evidence of long-term genetic or reproductive risks
Ecotoxicity: Harmful to aquatic species and plants due to strong alkalinity, rapidly changes pH balance in water
Persistence and Degradability: Dissociates completely in water, highly reactive and mobile in environment
Bioaccumulation: Does not bioaccumulate, breaks down to sodium and aluminum ions
Aquatic Impact: Spills cause immediate fish kills and harm to aquatic vegetation
Product Disposal: Neutralize with dilute acid under expert supervision, dispose of according to local environmental regulations
Container Disposal: Rinse thoroughly before recycling or disposal, contaminated containers treated as hazardous
Environmental Responsibility: Never discharge into drains or surface waters, always use approved waste management facilities
Legal Waste Codes: Follow local authority guidelines for alkaline, corrosive solids
UN Number: Classified as a corrosive solid for transport
Shipping Name: SODIUM ALUMINATE, SOLID
Hazard Class: Corrosive material, Transport regulations may require labeling and special packaging
Packaging: Use strong, sealed containers to prevent moisture ingress, mark containers with hazard warnings
Special Precautions: Avoid co-shipment with acids or flammable materials
Occupational Safety: Not subject to stringent workplace limits, but most guidelines recommend minimizing exposure to alkaline dusts
Environmental Regulation: Discharges regulated under clean water and hazardous substances statutes in many countries
Labeling Requirements: Corrosive symbol, hazard statements, and precautionary advice required under GHS or similar systems
Community Right-to-Know: Use and storage may be subject to local reporting requirements in some jurisdictions, especially for bulk users
