Recommended Use: Abrasive, refractory material, ceramics, catalyst support, filtration
Manufacturer: Supplier's contact information, including telephone and emergency contact numbers
Emergency Contact: Chemtrec or local emergency response number for spill, exposure, or fire situations
GHS Classification: Not classified as hazardous according to GHS
Physical Hazards: May act as irritant in dust form; fine particles can cause mechanical irritation to eyes, nose, and throat
Health Hazards: Inhalation of dust may cause coughing, sneezing, mild respiratory irritation
Environmental Hazards: No major environmental threat under normal conditions, but excess dust can affect local air quality
Warning Symbols: No symbol usually required
Signal Word: None applicable for most grades
Hazard Statements: Dust may be irritating to respiratory system
Chemical Name: Aluminum Oxide
Content: 98–100% by weight
Impurities: May contain trace elements such as sodium oxide, iron oxide, silicon dioxide depending on source
Molecular Weight: 101.96 g/mol
EC Number: 215-691-6
Inhalation: Move to fresh air; seek medical help if cough or breathing difficulty develops
Skin Contact: Wash gently with soap and water to remove particles; watch for persistent irritation
Eye Contact: Flush opened eyes with plenty of water for at least fifteen minutes to clear particles
Ingestion: Rinse mouth and drink water; seek medical attention if large amounts have been ingested or gastro symptoms arise
Notes to Physician: Remove source of exposure, treat symptomatically
Extinguishing Media: Use product appropriate to surrounding fire (water, foam, CO2, dry chemical), material itself does not burn
Specific Hazards: Product is non-combustible, does not contribute fuel to fire but dust could present slipping hazard
Protective Equipment: Standard firefighting gear and self-contained breathing apparatus in case of heavy dust or toxic fumes from surrounding fire
Special Precautions: Stay upwind to avoid inhaling airborne dust; avoid generating dust clouds during fire control
Personal Precautions: Wear dust mask, protective goggles, gloves to prevent eye/skin irritation
Environmental Precautions: Prevent dust spill into drains, water courses, or soil; use mechanical means to minimize dusting
Containment: Sweep or vacuum spillage in a way that minimizes airborne dust
Cleanup Methods: Collect in appropriate containers for disposal or recovery; wash area with water when cleared, making sure not to flush dust into drains
Handling: Use local exhaust or general ventilation to keep dust exposure below recommended limits; avoid dry sweeping or handling that raises dust; do not eat, drink, or smoke in work area
Storage: Store in sealed containers out of moisture; keep away from incompatible substances like strong acids; segregate from food and drink
Incompatible Materials: Strong acids, strong bases, some oxidizing agents
Exposure Limits: OSHA PEL: 15 mg/m³ (total dust); 5 mg/m³ (respirable fraction); ACGIH TLV: 1 mg/m³ (respirable fraction)
Engineering Controls: Use ventilation or dust collection to reduce exposure; maintain airborne concentrations below limits
Personal Protective Equipment: Protective safety goggles or face shield, gloves, long-sleeve clothing, NIOSH-approved respirator for dusty conditions; emergency eyewash stations in work area recommended
Hygiene Measures: Wash hands and exposed skin after handling; do not wear contaminated clothing away from workplace

Hazardous Decomposition Products: No hazardous decomposition products under normal conditions
Polymerization: Will not occur
Acute Toxicity: No significant acute toxicity expected by inhalation, ingestion, or skin contact at typical occupational exposures
Chronic Effects: Prolonged and repeated inhalation of dust may aggravate existing lung conditions; long-term exposure may slightly increase the risk of pneumoconiosis
Skin and Eye Irritation: Dust may cause mechanical irritation or redness
Carcinogenicity: Not classified as a carcinogen by IARC, NTP, or OSHA
Mutagenicity and Teratogenicity: No data suggesting these effects
Sensitization: Not known to cause sensitization
Environmental Fate: Stable in environment, non-degradable mineral
Mobility in Soil: No significant migration expected; insoluble in water
Bioaccumulation: Does not bioaccumulate; low toxicity to aquatic life
Ecotoxicity: No evidence of harm to plants or animals at ordinary usage
Persistence: Remains unchanged in soil and sediment
