Nickel(II) sulfamate hexahydrate (CAS 12471-48-2): 45–55% w/w Nickel(II) sulfate (CAS 7786-81-4): Variable, trace to <5% Boric acid (CAS 10043-35-3): Up to 5% Other Additives: Proprietary wetting agents, deionized water Impurities: Possible traces of cobalt, copper

4. First Aid Measures

Inhalation: Move to fresh air immediately, monitor breathing, seek medical advice if symptoms persist (headache, dizziness, shortage of breath) Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water and soap, seek medical attention if irritation or rash develops Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, get medical attention Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention, provide product label or description to the healthcare provider Most Important Symptoms: Rash, redness, swelling, respiratory distress, eye irritation, nausea Recommendations for Immediate Medical Attention: Any sign of respiratory involvement or chemical ingestion should lead to urgent evaluation

5. Fire-Fighting Measures

Suitable Extinguishing Media: CO₂, dry chemical, foam, or water spray Specific Hazards: Solution itself is not flammable but heating may produce toxic fumes including sulfur oxides and nickel oxides Protective Equipment: Self-contained breathing apparatus, full protective suit Firefighting Advice: Avoid runoff to water bodies, contain fire and firefighting water, stay upwind Decomposition Products: Sulfur dioxide, nickel oxide, ammonia, carbon oxides from additives

6. Accidental Release Measures

Personal Precautions: Wear gloves, safety goggles, chemical-resistant clothing, and an approved respirator Spill Containment: Evacuate area, ventilate, prevent entry into drains or watercourses, isolate as much as possible Cleanup Methods: Absorb with inert material (earth, sand or commercial absorbent), scoop into labeled chemical waste containers, wash area with large amounts of water, properly dispose according to local regulations Environmental Precautions: Prevent further leakage or spillage if safe to do so, nickel is extremely toxic to aquatic organisms Reference to Other Sections: Use PPE as described in Section 8, check waste disposal Section 13

7. Handling and Storage

Handling: Use in well-ventilated areas, avoid skin and eye contact, do not breathe vapors, never eat, drink, or smoke while working with chemical Storage: Store in tightly closed containers in cool, dry, ventilated place away from incompatible materials such as acids, oxidizers, reducing agents Technical Measures: Install spill trays, secondary containment, provide eyewash stations and emergency showers Incompatibilities: Strong acids, strong oxidizers, cyanides, strong reducing agents

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: Nickel compounds (as Ni): OSHA PEL 1 mg/m³; ACGIH TLV 0.1 mg/m³ Engineering Controls: Use local exhaust or general exhaust ventilation Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield, apron or coveralls, chemical safety shoes, NIOSH-approved respirator Hygiene Measures: Do not eat, drink, or smoke in work area; wash hands thoroughly after handling; handle with care to avoid splashes Monitoring: Air monitoring for nickel, routine health surveillance for workers handling nickel solutions

9. Physical and Chemical Properties

Appearance: Pale green to greenish-blue clear liquid Odor: No distinct odor pH: Acidic (generally 3–5) Melting/Freezing Point: Dependent on concentration; typically below 0°C for solution Boiling Point: Approx. 100°C (212°F) Flash Point: Not applicable (water-based solution) Evaporation Rate: Similar to water Solubility: Miscible with water in all proportions Density: 1.2–1.4 g/cm³ Vapor Pressure: Like water Viscosity: Slightly higher than water, varies with temperature and concentration Explosive Properties: Not explosive, but may release toxic gases at high temperature

10. Stability and Reactivity

Chemical Stability: Stable under recommended conditions of storage and use Reactive Materials: Reacts strongly with acids, cyanides, strong oxidizers, and reducing agents, evolving toxic gases Conditions to Avoid: High temperatures, direct sunlight, storage near incompatible substances Decomposition Products: Thermal decomposition produces nickel oxides, sulfur oxides, ammonia Polymerization: Will not occur

11. Toxicological Information

Acute Toxicity (Oral, Inhalation, Dermal): Harmful if swallowed or inhaled, can cause respiratory distress Skin Corrosion/Irritation: Causes irritation, may cause sensitization on repeated or prolonged contact Serious Eye Damage/Irritation: Severe irritation possible; risk increases with concentration Respiratory Sensitization: Nickel compounds can cause asthma-like symptoms Germ Cell Mutagenicity: Evidence of genetic toxicity observed in animal studies with nickel compounds Carcinogenicity: IARC, NTP, OSHA classify certain nickel compounds as carcinogenic Reproductive Toxicity: Nickel compounds linked to reproductive issues at high or repeated exposures Specific Target Organ Toxicity: Prolonged exposure can impact lungs, kidneys, skin Symptoms: Skin rash, cough, shortness of breath, eye irritation, nausea, metallic taste Chronic Effects: Dermatitis, lung fibrosis, cancer in workers with repeated exposure

12. Ecological Information

Ecotoxicity: Highly toxic to aquatic life, significant long-term adverse effects in aquatic environments Mobility: Solution mixes rapidly in water and can contaminate soil and waterways Persistence and Degradability: Nickel ions and sulfamate do not break down readily in the environment Bioaccumulative Potential: Nickel can accumulate in aquatic organisms and move up the food chain Other Adverse Effects: Hazardous residues can harm algae, invertebrates, and fish; large spills present severe risk to local ecosystems

13. Disposal Considerations

Disposal Methods: Dispose through licensed hazardous waste disposal contractor; do not flush into sewers, water systems, or normal landfill Contaminated Packaging: Triple rinse containers, send to hazardous waste handler Special Precautions: Notify appropriate environmental authorities if released to the environment Waste Code: US EPA hazardous waste code D006 (Nickel) Do Not: Discard residues in uncontrolled waste sites, open drains or public sewers
