Hazard Identification

GHS Classification: Not classified as hazardous under GHS criteria for most jurisdictions
Hazard Statements: May cause mechanical irritation to eyes, skin, and respiratory tract if exposed as dust
Precautionary Statements: Avoid inhalation, handle with proper personal protective equipment, minimize dust generation
Potential Health Effects: Eye irritation, mild respiratory discomfort, skin dryness or abrasion from extended contact
Environmental Hazard: Not considered environmentally hazardous in solid form, though large spills may impact soil or water bodies due to insoluble particulates

Composition / Information on Ingredients

Chemical Identity: Aluminum Tungstate
Formula: Al2(WO4)3
Concentration: Pure, ≥99% as Al2(WO4)3
Impurities: Trace metal oxides may be present depending on production route

First Aid Measures

Inhalation: Move person to fresh air, loosen tight clothing, seek medical attention if breathing difficulty persists
Skin Contact: Rinse area with plenty of water and mild soap, remove contaminated clothing
Eye Contact: Rinse eyes cautiously with water for at least 15 minutes, lifting eyelids, seek medical attention if irritation develops
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical attention if symptoms appear
Notes for Physicians: Treat symptomatically with attention to mechanical irritation from dust

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical, CO2, foam, or water spray for surrounding materials since substance is not flammable
Specific Hazards: Does not burn, stable in most fire scenarios, but metal oxide fumes may form if exposed to extreme heat
Protective Equipment for Firefighters: Wear standard full fire-fighting gear including self-contained breathing apparatus
Special Procedures: Minimize generation of airborne dust during and after fire suppression

Accidental Release Measures

Personal Precautions: Wear dust-proof goggles, gloves, and a suitable mask/respirator
Spill Handling: Scoop spilled material using clean, dry tools and place in labeled container for disposal; avoid creating airborne dust
Environmental Precautions: Prevent entry into drains and water supplies, avoid contamination of soil and surface water
Cleanup Methods: Moisten powder to reduce dust, clean area thoroughly to remove all particulates

Handling and Storage

Handling: Use in well-ventilated area, avoid generating dust, wear PPE appropriate to the potential for exposure
Hygiene: Wash hands before breaks and after handling, do not eat or smoke near product
Storage Conditions: Store in a cool, dry, and well-ventilated area, keep container tightly closed and labeled, segregate from acids and strong oxidizers
Container Requirements: Use solid, sealed containers made from compatible materials such as polyethylene or glass

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust ventilation or laboratory hoods to prevent airborne exposure
Occupational Exposure Limits: No established TLV or PEL for aluminum tungstate; for nuisance dust, follow local dust exposure guidelines (typically 10 mg/m³ for inhalable particulate)
Personal Protection: Safety goggles, dust mask or respirator (N95 or better), disposable gloves, long-sleeved clothing
Environmental Exposure: Use appropriate filters and capture systems to prevent release of powder into the workplace

Physical and Chemical Properties

Appearance: White or off-white crystalline powder
Odor: Odorless
pH: Not applicable (insoluble/very slightly soluble in water)
Melting Point: Decomposes at temperatures over 1000°C
Boiling Point: Not applicable
Solubility: Insoluble in water, soluble in strong acids
Density: ~5.7 g/cm³
Vapor Pressure: Not applicable
Other Properties: Stable under standard temperatures and pressures, non-flammable, not volatile

Stability and Reactivity

Chemical Stability: Stable in normal storage and use conditions
Reactivity: Reacts with strong acids, can form soluble tungstate and aluminum salts
Conditions to Avoid: Exposure to strong acids or bases, formation of airborne dust, extreme heat
Incompatible Materials: Strong acids, oxidizers
Hazardous Decomposition Products: At high temperatures, may release metal oxide fumes

Toxicological Information

Routes of Exposure: Inhalation, skin, eye contact
Acute Toxicity: Not acutely toxic, unlikely to cause systemic effects at typical exposure levels
Chronic Effects: Prolonged or repeated exposure to dust can cause lung or respiratory tract irritation
Sensitization: Not expected to cause allergy or sensitization
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Other Effects: No known chronic effects specific to aluminum tungstate; follow general dust exposure recommendations

Ecological Information

Ecotoxicity: Not expected to be hazardous to aquatic or terrestrial environments in solid form
Persistence: Highly stable, does not break down readily
Bioaccumulation: Not expected due to insolubility and chemical stability
Mobility: Essentially immobile in soil and sediment due to low solubility; dust can be transported by wind
Other Environmental Information: Minimize releases into water bodies and stormwater systems to avoid long-term particulate buildup

Disposal Considerations

Waste Disposal: Collect material in clearly labeled, sealed containers for transfer to licensed chemical waste disposal facility
Reuse/Recycling: Consider reuse in industrial applications if purity and contamination allow
Environmental Concerns: Avoid landfill disposal that could cause accumulation of heavy metals in soil
Regulatory Controls: Follow all federal, regional, and local regulations regarding non-hazardous but persistent inorganic waste

Transport Information

UN Number: Not regulated for transport
Proper Shipping Name: Aluminum Tungstate
Transport Hazard Class: Not classified as dangerous under ADR, IATA, or IMDG codes
Packing Group: Not assigned
Environmental Hazards: Not a marine pollutant
Special Transport Precautions: Secure containers to prevent damage or leaks, minimize contamination with other cargo

Regulatory Information

U.S. Regulations: Not listed as a hazardous substance under CERCLA, SARA 313, or OSHA hazardous chemicals; check state-specific lists for any additional requirements
EU Regulations: Not classified as hazardous under REACH regulation, no special labeling requirements
Canada: Not listed as a controlled product under WHMIS
Other Regulatory Information: Considered a non-hazardous, inorganic substance for general inventory and reporting; always check most current country or regional requirements before shipping or disposing
Additional Notes: Safety practices should align with recommendations for handling fine inorganic powders and avoid excessive or unnecessary environmental release
