Revision Date: 2024-06-01
Classification: Alloys classified under OSHA Hazard Communication Standard (29 CFR 1910.1200)
Physical Hazards: Dust poses risk of explosion in confined spaces; welding or machining generates particulate matter
Health Hazards: Prolonged inhalation of dust/fume may cause respiratory irritation, metal fume fever; skin or eye contact may lead to mild irritation
Environmental Hazards: Spilled fine powder can impact soil and water organisms; improper disposal increases heavy metal accumulation
Label Elements: Signal Word: Warning; Hazard Statements: May cause eye, skin, and respiratory irritation; May form combustible dust concentrations
Precautionary Statements: Avoid generating dust; wear appropriate protection; ensure proper ventilation; prevent environmental release
Routes of Entry: Inhalation, skin and eye contact, ingestion (rare, accidental)
Aluminum (Al): 80–95% by weight, CAS #7429-90-5
Nickel (Ni): 5–20% by weight, CAS #7440-02-0
Impurities: Typically less than 1%; can include traces of iron, silicon, copper, or cobalt from processing
Threshold Limits: OSHA PEL for aluminum: 15 mg/m3 (total dust); Nickel: 1 mg/m3 (elemental)
Inhalation: Remove exposed person to fresh air; seek medical attention if symptoms persist like coughing, shortness of breath, or chest tightness
Eye Contact: Rinse immediately with clean water for at least 15 minutes; remove contact lenses if present and easy to do; obtain medical advice for continued irritation
Skin Contact: Wash affected area thoroughly with soap and water; remove contaminated clothing and launder before reuse; do not scrub aggressively
Ingestion: Rinse mouth with water; seek medical attention if large quantities swallowed or symptoms arise (nausea, abdominal pain)
Acute Symptoms: Short-term exposure to fumes may result in metal fume fever, which resembles flu; eyes and skin manifest redness and irritation
Advice for Physicians: Symptomatic treatment recommended; no specific antidote for acute exposure to metal alloy
Suitable Extinguishing Media: Use Class D extinguishers (dry powder for metal fires), sand, or dry earth for metal dust fires; water may spread burning powder
Unsuitable Extinguishing Media: Do not use water or foam on burning powder; risk of explosion and spreading fire
Special Hazards: Fine dust and fumes combust easily and react with strong oxidizers; molten alloy at elevated temperature emits toxic metal oxides
Advice for Firefighters: Wear self-contained breathing apparatus; chemical-resistant turnout gear; isolate area; limit water runoff if fire involves metal dust
Explosion Risk: Heat and sparks generated by grinding, welding, or mixing may ignite combustible dust-air mixtures
Hazardous Combustion Products: Emits fumes of aluminum oxide and nickel oxide
Personal Protection: Wear approved respirator, gloves, eye and face protection
Containment Methods: Avoid dust generation; sweep up material and collect in suitable labeled container; keep away from water sources if metallic dust is present
Environmental Precautions: Prevent entry into drains or watercourses; report significant spills to authorities according to local regulations
Cleanup Techniques: Use non-sparking tools; do not use compressed air for cleaning; dispose of collected material according to waste regulations
Decontamination: Clean affected surfaces thoroughly to minimize long-term risk of fine powder residue
Safe Handling Guidelines: Minimize dust during material transfer and machining; use local ventilation where possible; avoid prolonged direct contact
Avoidance: Keep away from strong oxidizers, acids, and alkalis; do not handle near flames or high heat
Storage Instructions: Store in dry, well-ventilated area; keep containers sealable and closed when not in use; segregate from incompatible substances
Packing Materials: Use non-reactive containers such as polyethylene-lined drums or steel bins
Special Considerations: Implement regular housekeeping; train workers on metal dust risks
Engineering Controls: Provide local exhaust ventilation at points of dust or fume generation; review process enclosure if possible
Personal Protective Equipment: Wear approved particulate respirator during dusty operations; use safety goggles or face shield for eye protection; chemical-resistant gloves for skin
Hygiene Measures: Wash hands thoroughly after handling; remove contaminated clothing on-site before returning home
Exposure Guidelines: Maintain workplace concentrations below regulated limits; monitor air for particulate nickel and aluminum
Administrative Controls: Rotate tasks in high-exposure areas; restrict access to essential personnel
Appearance: Metallic gray lump, ingot, or powder
Odor: Odorless
Melting Point: 1450–1580°C (varies by composition)
Density: 2.8–7.9 g/cm3
Solubility: Nearly insoluble in water; reacts with acids to release hydrogen gas
Vapor Pressure: Not applicable at ambient temperatures
Evaporation Rate: Not relevant; solid at room temperature
pH: Not applicable
Flash Point: Not applicable; combustible as fine dust only
Flammability: Combustible dust when finely divided; bulk alloy not flammable
Partition Coefficient: Not relevant
Self-Heating: Negligible under normal conditions
Upper/Lower Flammability Limit: Not established for bulk alloy; dust may become flammable above certain concentrations in air
Chemical Stability: Stable under recommended handling and storage
Conditions to Avoid: Avoid open flames, excessive heat, and formation of fine powder clouds
Incompatibilities: Strong oxidizers, acids, halogens, water on molten alloy or dust
Hazardous Decomposition Products: Metal oxides, hydrogen gas (with acid)
Polymerization: No known hazard under typical uses
Reactive Risks: Dust may spontaneously ignite in air under certain conditions
Routes of Exposure: Inhalation of dust and fumes remains the highest risk pathway; incidental skin and eye contact can happen during handling
Effects from Short-Term Exposure: Dust or fume inhalation may cause irritation of nose, throat, and lungs; at high concentrations, metal fume fever (headache, fever, muscle aches)
Effects from Long-Term Exposure: Nickel classified as a carcinogen by IARC (Group 2B), linked to respiratory cancers with chronic exposure; aluminum dust in high doses associated with lung effects in industry
Skin Sensitization: Nickel can cause allergic reactions in sensitive individuals, presenting as dermatitis
Mutagenicity, Teratogenicity: Data limited; no well-established evidence for alloy
Acute Toxicity Data: LD50 values not specifically established for the alloy; for constituent metals, acute toxicity in animals only at doses unlikely in occupational settings
Aquatic Toxicity: Nickel compounds present toxicity risk to aquatic invertebrates and some fish; aluminum ions can impair fish health
Persistence and Degradability: Alloy form shows slow breakdown in the environment; ions can persist and bioaccumulate in sediments
Mobility in Soil: Fine powder shows some mobility, especially in acidic soils, where metal ions can leach into groundwater
Effects on Plants and Animals: Runoff from machining areas may inhibit plant growth and affect soil microbe health
Other Ecological Risks: Accumulated dust or misplaced waste risks local contamination near processing sites
Waste Disposal Methods: Send scrap, dust, and spent material to authorized metal recyclers; avoid disposal in domestic waste streams
Container Disposal: Triple rinse and render containers unusable before discarding through approved waste management
Environmental Precautions: Prevent release of dust into storm drains or public waterways; comply with local, regional, and national waste regulations for metals
Regulatory Status for Waste: Mostly handled as regulated non-hazardous industrial waste, except where soluble nickel content exceeds defined thresholds
