Concentration: 99% minimum
Impurities: Aluminum oxide, Free carbon at trace levels
Inhalation: Move to fresh air immediately. Call for medical attention if cough or breathing issues develop. Provide oxygen if necessary.
Skin Contact: Remove contaminated clothing. Rinse skin with water and soap for at least 20 minutes. Seek medical help if irritation continues.
Eye Contact: Rinse eyes with plenty of water for at least 20 minutes holding lids apart. Remove contact lenses after five minutes if present. Get urgent medical attention.
Ingestion: Do not induce vomiting. Rinse mouth thoroughly with water, give several glasses of water if conscious. Seek medical support right away.
Note to Physician: Treat for exposure to corrosive and water-reactive material; monitor for pulmonary symptoms or gastrointestinal distress
Suitable Extinguishing Media: Use dry sand or Class D powder extinguisher. Do not use water or foam.
Specific Hazards: Produces flammable gases (acetylene and methane) on contact with water; risk of explosion under fire conditions
Special Protective Equipment: Wear full protective gear including chemical-resistant suit, supplied-air respirator
Hazardous Combustion Products: May emit toxic and flammable gases such as carbon monoxide, aluminum oxide, methane, acetylene
Firefighting Instructions: Evacuate area, use remote firefighting techniques, avoid contact with spilled material
Explosion Risk: Powdered form can present dust explosion hazard under the right conditions
Personal Precautions: Wear dust mask, chemical goggles, gloves, and full body chemical protective clothing. Remove all sources of ignition.
Environmental Precautions: Prevent entry into water sources, drains, or soil by using barriers. Alert proper authorities for large spills.
Methods for Clean-up: Collect using non-sparking tools. Sweep up material carefully for recovery or disposal. Place in a dry, sealed, labeled container.
References for Handling: Only trained personnel should manage clean-up, follow local and national regulations
Handling: Work only in dry areas. Use airflow, fume hood, and non-sparking tools. Handle with dry gloves and avoid skin, eye, or clothing contact. Do not breathe dust or fumes.
Storage: Store in a cool, dry place in tightly closed, moisture-proof containers. Keep in a designated area for hazardous materials, away from water, acids, or oxidizers. Ensure storage containers are clearly labeled and separate from incompatible substances.
Additional Information: Regularly inspect containers for integrity or leaks and maintain ventilation
Engineering Controls: Use local exhaust ventilation to reduce airborne exposure. Enclosed processes or fume hoods recommended for dust or vapor control.
Personal Protective Equipment: Respiratory protection with NIOSH-approved mask, chemical splash-proof goggles, face shield, impervious gloves, flame-retardant lab coat, footwear resistant to chemicals
Occupational Exposure Limits: No ACGIH TLV for aluminum carbide exists; aluminum oxide's TLV can be referenced (10 mg/m3 total dust)
Hygiene Measures: Wash hands and face thoroughly after handling. Do not eat, drink, or smoke in work areas.
Monitoring: Regular air monitoring and health surveillance for workers recommended
Appearance: Gray-yellow to brown crystalline solid or powder
Odor: Odorless
Melting Point: 2200 °C
Boiling Point: Decomposes before boiling
Density: 2.36 g/cm3 at 25 °C
Solubility: Reacts with water
Vapor Pressure: Negligible
pH: Alkaline on reaction with water
Flammability: Non-flammable solid but generates flammable gases
Other: Decomposes in moist air, sensitive to acids
Chemical Stability: Stable in dry air, decomposes in presence of moisture
Reactivity: Violently reacts with water, acids, and moist air
Incompatible Materials: Water, acids, oxidizing agents, halogens
Decomposition Products: Methane, acetylene, aluminum hydroxide
Conditions to Avoid: Contact with water, humid environment, high temperature, open flames
Acute Toxicity: Inhalation or ingestion may cause irritation or toxicity to respiratory, digestive, and central nervous systems
Skin/ Eye Effects: Strong irritation, possible burns, redness, watering, blurred vision
Chronic Exposure: Prolonged inhalation can result in lung injury, fibrosis, or chronic respiratory conditions
Carcinogenicity: Not listed as carcinogenic by IARC, NTP, or OSHA
Reproductive Effects: No specific data for reproductive effects, but aluminum compounds can be linked to neurological issues
Symptoms of Exposure: Cough, nausea, headache, irritation, shortness of breath, abdominal pain
LD50 (oral, rat): 640 mg/kg (estimated, based on available analogs)
Environmental Impact: Highly reactive; reacts with water to form flammable gases, can raise pH and affect aquatic life
Persistence and Degradability: Rapidly decomposes on exposure to moisture, not persistent
Bioaccumulative Potential: Not expected to bioaccumulate due to rapid hydrolysis
Mobility in Soil: Limited mobility; decomposes on contact with moisture in soil
Toxicity to Aquatic Organisms: Rapid pH rise and aluminum hydroxide deposition may harm fish and invertebrates
Waste Treatment: Treat as hazardous waste. Neutralize cautiously under controlled conditions and dispose through a licensed treatment facility.
Disposal Containers: Use dry, sealed containers clearly marked for hazardous waste
Uncleaned Packaging: Dispose of containers after proper cleaning and neutralization according to local regulations
Legal Disposal: Compliance with federal, state, and local environmental control regulations needed
