Inhalation: Remove from exposure area to fresh air immediately, seek medical attention even if no symptoms are present; if breathing is difficult, qualified personnel should provide oxygen
Ingestion: Rinse mouth, do not induce vomiting, seek urgent medical care, never give anything by mouth to an unconscious person
Skin Contact: Remove contaminated clothing, rinse skin with copious amounts of water and mild soap, seek medical attention if irritation develops or persists
Eye Contact: Flush eyes for at least 15 minutes with running water, lifting upper and lower eyelids, obtain immediate medical attention
Symptoms of Exposure: Headache, cough, dizziness, shortness of breath, nausea, vomiting, potential kidney or liver damage, long-term carcinogenic risk
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Media: Do not use halogenated extinguishing agents; avoid direct water stream on material to prevent contaminated runoff
Special Hazards: Releases toxic fumes including cadmium oxides and nitrogen oxides at high temperatures
Protective Equipment: Firefighters must wear full protective gear and self-contained breathing apparatus
Explosion Risk: Strong oxidizer, enhances combustion of other materials, can increase fire intensity in contact with organic matter
Specific Methods: Use water spray to cool unopened containers surrounding the fire zone
Personal Protection: Evacuate unnecessary personnel, restrict entry, wear respiratory protection and full chemical-resistant clothing
Spill Cleanup: Do not touch spilled material, contain spill with inert absorbent, avoid creating dust, scoop up carefully and place in appropriate waste containers
Environmental Precautions: Prevent from entering drains, water courses, soil, and sewers, notify environmental authorities in case of large releases
Decontamination: Clean area with plenty of water and non-reactive soap, ventilate the area thoroughly
Disposal: Dispose of waste in accordance with local, regional, and national regulations
Precautions for Safe Handling: Avoid contact with skin, eyes, and clothing, do not inhale dust or fumes, use only in designated chemical fume hoods, handle with extreme care
Storage Conditions: Store in tightly sealed containers, in a dry, cool, well-ventilated area away from incompatible substances such as reducing agents, strong acids, and organics
Segregation: Keep away from heat sources and combustible materials, segregate from foods and animal feeds
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing and wash before reuse, do not eat, drink, or smoke when working with this material
Occupational Exposure Limits: OSHA PEL: 0.005 mg/m³ (Cadmium, dust and fumes), NIOSH REL: 0.002 mg/m³
Engineering Controls: Local exhaust ventilation, chemical-resistant work surfaces, safety showers, and eyewash stations in proximity
Personal Protective Equipment: NIOSH-approved respirators, chemical-resistant gloves (nitrile, neoprene), impervious lab coats or coveralls, chemical splash goggles, face shield for splash risk

Density: Approximately 2.45 g/cm³ (tetrahydrate)
Solubility: Very soluble in water, soluble in methanol
pH: Acidic aqueous solution, pH depends on concentration
Vapor Pressure: Not significant at ambient temperature
Other Properties: Strong oxidizer, can accelerate combustion
Chemical Stability: Stable under dry, cool, and well-ventilated storage conditions
Reactive Hazards: Reacts violently with strong acids, reducing agents, combustible materials; generates toxic fumes under fire conditions
Incompatible Materials: Reducing agents, strong acids, sulfides, organic materials, chlorinated hydrocarbons
Hazardous Decomposition: Cadmium oxides, nitrogen oxides, potentially explosive nitrates and nitrites can form in certain conditions
Polymerization: Does not undergo hazardous polymerization
Acute Toxicity: Oral LD50 (rat): 300 mg/kg (as cadmium nitrate); Inhalation LC50 (rat): 30 mg/m³/2hr
Chronic Exposure: Implicated in kidney, liver, lung damage, and bone demineralization, classified as a Group 1 carcinogen (IARC)
Sensitization: May trigger allergic skin or respiratory reactions
Mutagenicity: Evidence suggests potential for causing genetic mutations
Health Hazards: Causes severe irritation to eyes, skin, and respiratory tract, can depress central nervous system, implicates reproductive toxicity
Cancer Risk: Confirmed human carcinogen with sufficient evidence from occupational exposure
Aquatic Toxicity: Very toxic to aquatic organisms with long-lasting effects, cadmium ions bioaccumulate in fish and aquatic life
Persistence/Degradability: Not degradable, cadmium persists and remains mobile in soil and water
Bioaccumulative Potential: High, due to strong binding in aquatic and terrestrial organisms
Mobility in Soil: Can migrate through soil and pose risk to groundwater
Other Environmental Hazards: Disruption of microbial activity in soil, contamination risk for food chains through plant uptake
Waste Treatment Methods: Dispose as hazardous waste in accordance with local, state, and federal requirements, do not release to the environment
Contaminated Packaging: Rinse containers with copious water before disposing, prevent reuse of packaging for other chemicals
