Inhalation: Move person to fresh air. Seek medical attention if symptoms like coughing or difficulty breathing occur.
Skin Contact: Remove contaminated clothing. Wash with plenty of water and soap for at least 15 minutes. If irritation or rash develops, get medical help.
Eye Contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses if present. Continue rinsing and get immediate medical attention.
Ingestion: Rinse mouth with water and never induce vomiting. Seek immediate medical attention, as ingestion can cause severe health effects.
Acute Symptoms: Irritation of respiratory tract, eyes, skin; potential sensitization; risk of delayed effects due to carcinogenicity and organ toxicity.
Suitable Extinguishing Agents: Use water spray, carbon dioxide, or foam—small fires can be smothered with sand.
Unsuitable Extinguishing Agents: Do not use dry chemical powder as it may react violently.
Specific Hazards: Powerful oxidizer, supports combustion of flammable materials, decomposes under heat to release toxic nitrogen oxides and nickel oxides. Risk of explosions if in contact with reducing agents or organic material.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Advice: Avoid inhaling fumes and runoff water; prevent extrapolation into drains.
Personal Precautions: Evacuate area, prevent unprotected personnel from entering, avoid dust formation, wear suitable protective clothing including gloves, goggles, and respirator.
Environmental Precautions: Prevent spillage from entering drains, water courses, or soil.
Spill Cleanup: Scoop up material into suitable disposal containers using non-combustible absorbent material. Wash contaminated surfaces with water, ventilate area.
Disposal: Keep spilled material in closed containers for regulatory disposal.
Decontamination: Neutralize rinse water where legally required before discharge.
Handling: Only handle in well-ventilated areas, avoid formation of airborne dust, wear appropriate PPE, wash hands thoroughly after handling, do not eat, drink, or smoke in working area, avoid contact with skin and eyes, keep away from reducing agents and flammable materials.
Storage: Store locked up in a cool, dry, well-ventilated area away from direct sunlight, separate from acids, organics, combustibles, and reducing agents, store containers tightly closed and upright to prevent leaks, use corrosion-resistant shelves, maintain secondary containment to manage potential spills.
Incompatibles: Reducing agents, organics, sulfur, phosphorus, powdered metals, strong acids.
Special Storage Requirements: Ensure suitable labeling and access to emergency showers and eye wash stations.
Exposure Limits: Nickel compounds—OSHA PEL: 1 mg/m³ TWA (as Ni), NIOSH REL: 0.015 mg/m³ (as Ni), ACGIH TLV: 0.1 mg/m³ (inhalable fraction as Ni).
Engineering Controls: Use local exhaust ventilation, enclosed processes, dust extraction systems near emission sources, fume hoods in labs.
Personal Protections: Safety goggles or face shield, chemical-resistant gloves (nitrile or neoprene), protective clothing (lab coat, apron), respiratory protection (P2 or N95 mask), use lined footwear where significant splashing possible.
Hygiene Measures: Wash hands and face before breaks or smokers’ areas, remove contaminated clothing, and launder prior to reuse.
Environmental Controls: Use chemical spill barriers and neutralization pads where risk of release exists.
Appearance: Emerald green, crystalline solid

Solubility: Highly soluble in water (at 20°C, 94.5 g/100 mL); also soluble in alcohol
Vapor Pressure: Negligible at room temperature
Partition Coefficient (log Kow): Not applicable
Decomposition Temperature: >56.7°C
Other Properties: Non-combustible, strong oxidizer, generates heat on contact with water, corrosion risk to most metals.
Chemical Stability: Stable in sealed containers under recommended conditions, decomposes rapidly as temperature increases.
Reactivity: Intensely reactive with reducing agents, powdered metals, organic material, and acids.
Hazardous Reactions: Contact with flammable materials or reducing agents can result in fire or explosion, generates toxic nitrogen oxide gases.
Incompatible Materials: Reducing agents, combustible materials, acids, powdered metals, sulfur, phosphorus.
Hazardous Decomposition Products: Nitrogen oxides, nickel oxides, oxygen.
Other Stability Concerns: Deliquescent (absorbs moisture from air), accelerates corrosion of standard metal containers.
Acute Toxicity: LD50 oral (rat) approximately 175 mg/kg; LD50 dermal (rat) approximately 2,000 mg/kg; inhalation exposure linked to respiratory irritation.
Chronic Effects: Prolonged or repeated exposure increases sensitization risk (skin and respiratory), recognized human carcinogen (IARC Group 1), possible mutagenic and reproductive toxicity evidenced in animal studies.
Symptoms of Exposure: Eye, skin, respiratory irritation, skin redness, coughing, headache, pulmonary symptoms, dermatitis, nickel allergy, in severe cases, systemic organ toxicity.
Other Effects: May aggravate pre-existing conditions (asthma, allergies, respiratory disease, dermatitis).
Additional Risks: Ingestion is hazardous due to systemic nickel poisoning.
Ecotoxicity: Toxic to aquatic organisms; LC50 (96h, fish) = ~1.3 mg/L.
Persistence and Degradability: Nickel resists degradation in aquatic environments.
Bioaccumulation Potential: Can bioaccumulate in aquatic species, posing food chain risk.
Soil Mobility: Component disperses readily on release; forms soluble complexes with nitrates.
Aquatic Impact: Promotes chemical oxygen demand, disrupts aquatic life, causes coloring and toxicity issues.
Other Environmental Hazards: Pollution via improper disposal increases nitrate/nickel load in rivers, impairing drinking water departments.
Waste Disposal: Collect and seal in labeled hazardous waste containers, prohibit discharge into sewers or waterways; manage as hazardous—ideally through licensed chemical waste contractor.
Disposal Methods: Incinerate using facilities with proper gas scrubbing, or chemical reduction/precipitation prior to landfill disposal according to local regulations.
