First Aid Measures

Inhalation: Move person to fresh air immediately. Keep at rest. Give artificial respiration if not breathing. Seek medical attention quickly.
Skin Contact: Remove contaminated clothing. Rinse skin thoroughly with plenty of water and soap. Seek medical advice if irritation occurs.
Eye Contact: Rinse immediately with plenty of water for at least fifteen minutes. Lift eyelids. Remove contact lenses if present. Seek prompt medical attention.
Ingestion: Rinse mouth; do not induce vomiting. Give plenty of water to drink only if person is conscious. Contact a poison control center and get medical help at once.
Most Important Symptoms/Effects: Allergic skin reactions, respiratory irritation, abdominal cramps, nausea, vomiting, headaches, risk of chronic exposure resulting in carcinogenic effects.

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, carbon dioxide, dry chemical, foam
Unsuitable Extinguishing Media: Avoid high-volume water jet
Special Hazards: Decomposition releases hydrogen bromide and nickel oxides, both of which are hazardous to respiratory health.
Protective Equipment: Firefighters must use full protective gear, including self-contained breathing apparatus.
Advice for Firefighters: Approach from upwind, keep unnecessary people away, and avoid inhaling vapors or dust generated during fire.

Accidental Release Measures

Personal Precautions: Wear appropriate personal protective equipment, including gloves, goggles, and suitable respiratory protection.
Environmental Precautions: Prevent product from entering drains, surface water, or soil.
Cleanup Methods: Sweep up carefully to avoid dust formation. Collect in labeled, sealed containers for disposal. Ventilate area.
Decontamination: Wash spill site with water after material pickup is complete.
Additional Advice: Isolate hazard area, restrict access, and notify relevant authorities immediately if spillage contaminates water or soil.

Handling and Storage

Handling: Only use in a well-ventilated area. Wear recommended personal protective equipment. Avoid skin and eye contact and breathing of dust. Keep containers closed when not in use.
Storage Conditions: Store in a cool, dry, and well-ventilated area, away from moisture and incompatible substances such as oxidizing agents and acids.
Specific Storage Requirements: Use corrosion-resistant containers. Label containers clearly. Store away from direct sunlight.
Hygiene Practices: Wash hands thoroughly after handling. Do not eat, drink, or smoke during use.

Exposure Controls and Personal Protection

Occupational Exposure Limits: Nickel compounds (as Ni): OSHA PEL 1 mg/m³ (TWA), ACGIH TLV 0.1 mg/m³ (inhalable fraction)
Engineering Controls: Local exhaust ventilation or other engineering controls to keep airborne levels below recommended exposure limits.
Personal Protective Equipment: Nitrile or rubber gloves, safety goggles, lab coat or chemical-resistant clothing, NIOSH-approved respirator in case of inadequate ventilation.
Other Protection Measures: Emergency eyewash stations and safety showers nearby. Ensure all work with the substance takes place inside chemical fume hoods where possible.
Environmental Controls: Avoid discharge into the environment. Use containment measures where spills might occur.

Toxicological Information

Acute Toxicity: Toxic by ingestion, inhalation, and skin contact. LD₅₀ data (rat, oral): 38 mg/kg for nickel bromide (anhydrous)
Chronic Effects: May cause allergic dermatitis with prolonged or repeated exposure. Nickel compounds classified as possibly carcinogenic to humans (IARC Group 2B).
Routes of Exposure: Inhalation, ingestion, skin and eye contact.
Symptoms: Irritation, respiratory distress, nausea, vomiting, headache, dermatitis, risk of kidney and lung damage from chronic exposure.
Carcinogenicity: Evidence from human and animal studies links nickel compounds to increased risk of lung and nasal cancers.
Other Health Hazards: Sensitization, reproductive and developmental toxicity with long-term exposure.

Ecological Information

Ecotoxicity: Highly toxic to aquatic organisms. Nickel bromide can cause long-term adverse effects in the aquatic environment.
Persistence and Degradability: Nickel and bromide ions are persistent in the environment.
Bioaccumulation: Nickel accumulates in aquatic organisms and can enter food chains.
Mobility in Soil: Nickel compounds can leach into groundwater under certain soil conditions.
Other Ecological Hazards: Insoluble forms may accumulate in sediment, affecting benthic organisms and ecosystem health.
Further Information: Avoid release to water sources and inform downstream users or authorities of accidental releases.

Disposal Considerations

Waste Treatment Methods: Collect and dispose of waste according to local, regional, and national regulations.
Disposal of Container: Triple rinse, deface label, and dispose in accordance with environmental regulations.
