CAS Number: 1344-28-1
Recommended Use: Abrasives, refractories, ceramics, lab reagents, electrical insulators
Manufacturer: Various chemical producers and suppliers
Contact Information: Supplier emergency phone numbers and addresses provided with each shipment
Emergency Telephone: Contact poison control, fire department, or supplier for any emergency
Classification: Non-flammable, dust inhalation hazard, not classed as hazardous per OSHA/GHS
Main Hazards: Inhalation of fine dust may cause respiratory irritation or worsen lung conditions, possible eye and skin irritation, can lead to mechanical irritation of the upper respiratory tract
Signal Words: Warning for dust generation
Precautionary Statements: Avoid breathing dust, use local exhaust ventilation, avoid skin and eye contact, wash exposed areas after handling
GHS Symbol: Exclamation mark for respiratory and eye irritation
Potential Health Effects: Chronic inhalation may aggravate pre-existing respiratory conditions, no significant carcinogenic risks identified by IARC or NTP
Chemical Formula: Al2O3
Concentration: 99.0% or higher, depending on grade
Other Ingredients: Minor trace impurities (including silica and iron oxides) under 1.0%
Impurities Affecting Safety: Low; bulk material contains no hazardous impurities above reportable limits
Eye Contact: Flush eyes with running water for several minutes, remove contact lenses if present and easy to do, seek medical attention if irritation persists
Skin Contact: Wash exposed skin with soap and water, remove contaminated clothing, seek medical help for irritation
Inhalation: Move person to fresh air, encourage deep breathing, consult a physician if discomfort continues
Ingestion: Rinse mouth, do not induce vomiting, drink water to dilute, seek medical attention if large amounts swallowed or discomfort develops
Flammability: Non-combustible, does not support fire
Explosion Risk: Dust may contribute to mechanical irritation but does not pose an explosion hazard, no thermal decomposition to hazardous gases under standard fire conditions
Extinguishing Media: Use extinguishing measures suitable for surrounding fire, such as water spray, dry chemical, foam, or carbon dioxide
Protective Equipment: Firefighters should wear full protective gear including self-contained breathing apparatus to avoid inhalation of dust or combustion byproducts from surrounding materials
Special Precautions: Avoid inhaling dust generated from water jets or agitation, contain firefighting run-off for proper disposal
Personal Protection: Wear dust mask, safety goggles, gloves, and long sleeves to prevent irritation
Environmental Precautions: Prevent dust from entering sewers or waterways, minimize airborne dispersion
Cleanup Methods: Vacuum up spilled material using equipment fitted with HEPA filter or damp sweep to reduce airborne dust, collect in suitable container for disposal
Waste Handling: Place cleanup residues in tightly sealed containers for approved disposal, wash spill area with water
Safe Handling: Minimize dust generation and accumulation, use local exhaust ventilation, avoid eating or drinking in work areas, wash hands thoroughly after handling
Storage Conditions: Keep containers tightly sealed when not in use, store in dry, cool, well-ventilated area away from incompatible substances like strong acids
Incompatibles: Avoid storing near strong acids or bases, halogenated hydrocarbons, or reactive metals
Hygiene Practices: Change out of work clothes before leaving the area, regularly clean surfaces to avoid dust buildup
Exposure Limits: OSHA PEL for inert dust 15 mg/m³ (total dust), 5 mg/m³ (respirable fraction); ACGIH TLV 1 mg/m³ (respirable particulate matter, non-asbestos and not otherwise classified); check workplace-specific requirements
Engineering Controls: Use local exhaust, general ventilation, and dust suppression systems
Personal Protection: Wear approved respirators for dusty operations, safety goggles or face shields, chemical-resistant gloves, protective clothing for prolonged or repeated use
Hygiene Measures: Wash hands and face before breaks or after handling, do not eat or smoke in work areas
Appearance: White, off-white, or transparent, fine to coarse powder or crystals
Odor: Odorless
Melting Point: Approximately 2,072°C (3,762°F)
Boiling Point: Approximately 2,977°C (5,391°F)
Density: 3.9 to 4.0 g/cm³
Vapor Pressure: Not applicable
Solubility in Water: Insoluble
pH: 7.0 (neutral, in water suspension)
Partition Coefficient (n-octanol/water): Not applicable
Evaporation Rate: Not volatile
Flash Point: Not relevant, not combustible
Upper/Lower Explosive Limits: Not applicable
Stability: Chemically stable under normal conditions
Polymerization: Will not occur
Conditions to Avoid: Contact with strong acids, high temperature reactions with reducing agents
Incompatible Materials: Avoid strong acids (may react to release heat), halogenated hydrocarbons, reactive metals like magnesium or calcium
Hazardous Decomposition Products: None under normal use; with strong acids may produce heat and release trace gases
Routes of Exposure: Inhalation, skin and eye contact, incidental ingestion
Acute Toxicity: Low to negligible, may cause mechanical irritation to eyes, skin, and respiratory tract
Chronic Effects: Prolonged inhalation of high concentrations can cause lung irritation, no clear evidence of carcinogenicity or reproductive harm in humans
Medical Conditions Aggravated: Persons with existing respiratory conditions like asthma or bronchitis might experience increased symptoms
Special Sensitivities: No evidence of sensitization or allergic skin response
Ecotoxicity: Low toxicity to aquatic and terrestrial organisms, does not bioaccumulate
Persistence and Degradability: Inert, not degradable, persists as a mineral in the environment
Mobility: Very low; due to insolubility and tendency to remain localized in soil or sediment
Other Environmental Issues: Large spills may smother plants or aquatic life by physical coverage, control dust to reduce local air pollution effects
Waste Disposal: Follow all local, regional, and national regulations, typically permits landfill disposal as non-hazardous waste
Container Disposal: Empty containers should be dust-free before disposal, reuse or recycle when possible, otherwise handle as inert solid waste
Special Precautions: Do not dispose into sewers or natural waterways, avoid dispersal of dust
ID/UN Number: Not regulated as dangerous goods for transport by DOT, IATA, or IMDG
Proper Shipping Name: Aluminum Oxide
Hazard Class: Not regulated
Packing Group: Not assigned
Label Requirements: None for transportation, may require “dust hazard” in large quantities by company policy
Special Precautions for Transport: Keep containers secure and dry to avoid release of dust during movement
OSHA: Not classified as a hazardous material in bulk; subject to worker exposure standards for particulates
SARA 313: Not listed for emergency planning or toxic chemical release reporting
TSCA: Listed on the Toxic Substances Control Act inventory
REACH: Registered as a low-concern substance in the EU, requires no specific authorization for most uses
California Proposition 65: Not listed
Canada WHMIS: Not classified as hazardous
Other Regulations: Complies with relevant country regulations, recommended good industrial hygiene and safety practices while handling and transporting
