Concentration: ≥98% by weight (typical commercial purity)
Impurities: Trace magnesium nitrate, sodium nitrate, water of crystallization in tetrahydrate form
Inhalation: Move to fresh air, keep at rest, seek medical attention for discomfort, provide artificial respiration if breathing stops
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical advice if irritation persists
Eye Contact: Flush eyes with copious water for at least 15 minutes, remove contact lenses if present, get immediate medical attention
Ingestion: Rinse mouth, seek medical help, do not induce vomiting unless directed by medical personnel
Symptoms: Redness, watering eyes, dry throat, possible mild burns on skin or eye tissue
Most Important Effects: Eye damage or irritation, respiratory tract discomfort, upset stomach if swallowed
Suitable Extinguishing Media: Use water spray, fog, or foam—avoid dry chemical or carbon dioxide
Unsuitable Media: Do not use dry chemical extinguishers or CO2 as powder may react
Hazards from Product: Supports combustion, may decompose releasing toxic oxides of nitrogen
Protective Equipment: Firefighters need self-contained breathing apparatus and protective gear
Precautions: Isolate area, keep containers cool with water spray, avoid contact with burning material
Special Instructions: Remove combustible materials, prevent runoff into sewers or waterways
Personal Protections: Evacuate area, wear respiratory protection, avoid eye and skin contact
Containment: Collect spilled material, avoid generating dust, use vacuum with HEPA filter if available
Spill Cleanup: Sweep up carefully, place in appropriate container for reuse or disposal, wash area with water after collecting solid
Environmental Precautions: Prevent release to drains, watercourses, or soil; notify authorities in case of major leak
Precautionary Actions: Remove sources of ignition, keep incompatible materials away during cleanup
Handling: Keep away from heat, flames, and reducing agents, avoid dust generation, use with good ventilation
Personal Hygiene: Wash hands after handling, do not eat, drink, or smoke in areas where product is handled
Storage Conditions: Store in a cool, dry, well-ventilated area away from combustible materials and acids
Container Materials: Use plastic, stainless steel, or lined steel containers; avoid wood or aluminum
Segregation: Keep away from organic materials, sulfur, powdered metals, and reducing agents
Occupational Exposure Limits: No established limits for calcium nitrate; use as low as reasonably achievable and control workplace dust
Engineering Controls: Local exhaust ventilation, enclosed process equipment, dust collection systems recommended
Personal Protective Equipment: Safety glasses or goggles, chemical-resistant gloves, dust mask or respirator (NIOSH approved), protective clothing
Hygiene Measures: Wash hands before breaks and after use, change contaminated clothing, do not carry product residue home
Appearance: White or colorless crystals, may appear as granular solid
Odor: Odorless
Molecular Weight: 164.1 g/mol (anhydrous)
Melting Point: 561°C (anhydrous), decomposes on heating
Boiling Point: Decomposes before boiling
Density: 2.36 g/cm3 (tetrahydrate)
pH (in solution): 5 – 7 in 10% aqueous solution
Solubility: Very soluble in water
Vapor Pressure: Negligible
Flash Point: Not applicable (non-flammable)
Decomposition Temperature: >500°C, with toxic gases released
Chemical Stability: Stable in original packaging under recommended conditions
Conditions to Avoid: High humidity, heat, sunlight, sources of ignition, incompatible substances
Incompatible Materials: Reducing agents, organic materials, combustible substances, strong acids, sulfur, finely powdered metals
Hazardous Decomposition: Nitrogen oxides, calcium oxide, possible toxic fumes if heated
Reactivity Hazards: Strong oxidizer, may react vigorously or cause fire near combustible or reducing agents
Acute Toxicity: LD50 (oral, rat) approximately 3000 mg/kg
Skin Irritation: Prolonged or repeated contact causes irritation
Eye Irritation: Causes severe irritation, possible damage to cornea with direct contact
Respiratory Effects: Dust irritates airways, high exposures lead to coughing or sore throat
Chronic Effects: No human data for long-term exposure, but animal studies do not show significant chronic toxicity under typical exposure
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, OSHA
Mutagenicity: No known mutagenic effects
Aquatic Toxicity: Hazardous to aquatic life due to nutrient overload and potential eutrophication
Persistence and Degradability: Highly soluble, dissociates in water to release nitrate ions; nitrates remain in the aquatic environment
Bioaccumulation: Unlikely to bioaccumulate due to water solubility
Mobility in Soil: Easily moves through soils, may reach groundwater
Environmental Concerns: Excessive nitrate runoff can cause algal blooms and oxygen depletion in water bodies
Product Disposal: Dispose as hazardous waste under local regulations, dilute before disposal with water for small amounts if allowed, consult local environmental authorities
Packaging Disposal: Empty containers thoroughly, can be recycled after cleaning, do not reuse for other chemicals
Precautionary Measures: Avoid uncontrolled discharge to environment, follow all local, regional, and national regulations
Waste Code: Refer to official local waste code registry
