CAS Number: 373-02-4
Recommended Use: Metal finishing, electroplating, laboratory reagent, catalyst for chemical reactions
Supplier Information: Manufacturer’s full address and emergency contact details, though specifics vary by supplier
2. Hazard Identification
Classification: Toxic to humans, environmentally hazardous, skin and respiratory sensitizer
Main Hazards: Potent skin irritant, carcinogenic risk on repeated exposure, triggers respiratory reactions, can damage the liver and kidneys over long periods
Label Elements: Skull and crossbones for acute toxicity; exclamation mark for irritation; health hazard symbol for carcinogenicity; aquatic toxicity symbol
Signal Word: Danger
Precautionary Statements: Avoid inhalation or contact with skin, wear protective clothing and gloves, wash thoroughly after use, avoid contamination of the environment
3. Composition / Information on Ingredients
Chemical Name: Nickel Acetate Anhydrous
Concentration: 98–100%
CAS Number: 373-02-4
Impurities: Trace water and organic impurities, usually less than 2%
Molecular Weight: 204.78 g/mol
4. First Aid Measures
Inhalation: Remove the affected person to fresh air, keep warm, provide medical attention for breathing difficulties; monitor for signs of respiratory sensitization
Skin Contact: Wash immediately with large volumes of water and mild soap, remove contaminated clothing, consult a physician for persistent irritation or burns
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, seek medical advice if irritation remains
Ingestion: Rinse mouth, do not induce vomiting, get medical help quickly, monitor for signs of systemic nickel poisoning such as nausea, vomiting, or abdominal pain
5. Fire-Fighting Measures
Suitable Extinguishing Media: Water spray, dry chemical powder, foam, carbon dioxide
Specific Hazards: Heating releases toxic nickel oxides and acetic acid vapors, risk increases in confined spaces
Protective Equipment: Firefighters require self-contained breathing apparatus, complete protective gear to avoid inhaling metal fumes
Recommendations: Use cool water to prevent spread of vapors, avoid runoff into drains or watercourses, isolate area, ventilate after extinguishing
6. Accidental Release Measures
Personal Protection: Full chemical-resistant gloves, goggles, lab coat, breathing protection in dusty environments
Environmental Precaution: Prevent entry into sewer or waterways, alert authorities if accidental contamination occurs
Clean-Up Methods: Sweep up gently without generating dust, collect in sealed, labeled containers for disposal, wash the spill site thoroughly, ventilate area
Decontamination: Use diluted acetic acid or comprehensive detergent cleaning for facilities and equipment
7. Handling and Storage
Handling: Handle with care in a well-ventilated space, use fume hoods for large amounts, ground all equipment to avoid static discharge, never eat, drink, or smoke in work area
Storage: Store in tightly sealed containers, keep cool, dry, and away from acids and foodstuffs, label containers properly, check regularly for corrosion or leaks, restrict access to authorized persons only
8. Exposure Controls and Personal Protection
Occupational Exposure Limits: OSHA PEL (TWA): 1 mg/m3 (as nickel); ACGIH TLV (TWA): 0.1 mg/m3
Engineering Controls: Local exhaust ventilation, glove boxes for powder handling, closed systems for large scale work
Personal Protective Equipment: Respiratory protection (NIOSH-approved mask), chemical-resistant gloves, safety goggles, face shield for splash risk, flame-retardant coveralls
Hygiene Measures: Wash hands and exposed skin after handling, change work clothes before leaving facility, avoid bring materials home
9. Physical and Chemical Properties
Appearance: Pale green crystalline powder
Odor: Slight acetic smell
Melting Point: Decomposes before melting at around 317°C
Solubility: Soluble in water, alcohol
Density: 1.744 g/cm3
pH: Neutral to slightly acidic in aqueous solution
Boiling Point: Not applicable (decomposes)
Vapor Pressure: Very low at room temperature
Other Data: Stable under standard conditions, prone to hydrate over time under high humidity
10. Stability and Reactivity
Chemical Stability: Stable under recommended storage, reacts with strong acids or oxidizers
Possible Reactions: Releases nickel oxides under intense heat, can form flammable acetic acid vapors with moisture
Incompatible Substances: Strong acids, alkali metals, oxidizing agents
Hazardous Decomposition Products: Nickel oxides, acetic acid fumes
11. Toxicological Information
Acute Toxicity: Inhalation and ingestion can cause nausea, headaches, lung irritation, abdominal pain
Chronic Toxicity: Linked to risk of cancer after long-term or repeated exposure, can damage kidneys, liver, lungs, and trigger skin sensitization
Routes of Exposure: Most harm occurs from inhalation or repeated skin contact
Carcinogenicity: Classified by IARC as Group 1 (carcinogenic to humans)
Signs of Poisoning: Respiratory distress, metallic taste, skin rashes, chronic cough
12. Ecological Information
Ecotoxicity: Very toxic to aquatic life, persistent in water and soils, bioaccumulates in fish and plants
Mobility: Nickel ions readily migrate in moist environments, leach into groundwater
Persistence and Degradability: Nickel compounds do not degrade, persist in the environment for decades
Bioaccumulation: Classified for significant bioaccumulation in aquatic organisms
13. Disposal Considerations
Waste Treatment Methods: Collect in sealed, labeled containers, hand off to licensed hazardous waste contractors
Contaminated Containers: Empty containers treated as hazardous; require rinsing and regulated disposal
Disposal Restrictions: Never dispose of in regular trash, sink, or landfill; incineration by authorized facilities ensures safe destruction
Regulatory Considerations: Follow local, national, and international chemical disposal guidelines and obtain waste shipment documentation
14. Transport Information

Proper Shipping Name: Toxic solid, inorganic, n.o.s. (Nickel acetate anhydrous)
Transport Hazard Class: 6.1 (Toxic substances)
Packing Group: III
Label Requirements: Toxic substance label, environmental hazard label
Special Precautions: Ship in secure, sealed containment; avoid packages with loose powder; keep documentation handy for authorities; emergency access to safety data sheets
15. Regulatory Information
