Impurities: Maximum impurity levels as per supplier specification, generally under 2%
Inhalation: Remove victim to fresh air immediately. Seek medical attention if symptoms persist. Provide oxygen if breathing is difficult.
Skin Contact: Remove contaminated clothing and wash skin with plenty of water and soap. Get medical help for irritation or rash.
Eye Contact: Rinse thoroughly with water for several minutes, holding eyelids apart. Remove contact lenses if present, continue rinsing. Consult physician.
Ingestion: Rinse mouth, do not induce vomiting unless directed by a medical professional. Seek immediate medical attention.
Symptoms: Coughing, throat irritation, skin and eye redness, abdominal discomfort or pain.
Special Advice: Provide material MSDS and product label to attending health professionals.
Suitable Extinguishing Media: Water spray, foam, dry chemical, CO2—avoid dry combustibles due to oxidizing properties.
Specific Hazards: Strong oxidizer, increases fire intensity. May decompose producing toxic nitrogen oxides and zirconium oxide dust.
Protective Equipment: Full firefighting gear, self-contained breathing apparatus (SCBA).
Firefighting Procedures: Keep product containers cool using water spray. Prevent runoff into drains or water sources.
Combustion Products: Nitrous gases, metallic oxides
Personal Protection: Wear chemical-resistant gloves, splash goggles, lab coat, and dust respirator.
Evacuation Procedures: Ventilate area, isolate spill. Remove ignition sources.
Cleanup Methods: Scoop up spilled material without creating dust, place in a suitable labeled container for waste. Use inert absorbing material (vermiculite, dry sand).
Environmental Precautions: Prevent entry into waterways, sewers, basements, or confined areas.
Disposal: Dispose gathered material according to local, regional, national, and international regulations.
Decontamination: Wash spill site with water after material pickup is complete.
Handling: Use only in well-ventilated areas. Minimize dust formation. Avoid contact with eyes, skin, and clothing. Never handle near heat sources or combustible materials.
Hygiene: Wash hands and face before eating, drinking, or smoking. Remove contaminated clothing.
Storage Conditions: Store in tightly closed, labeled containers in a cool, dry, well-ventilated space away from direct sunlight, incompatible materials, and foodstuffs.
Incompatible Materials: Strong reducing agents, organic materials, combustibles, powdered metals.
Packaging Materials: Store in non-reactive containers such as polyethylene or glass.
Occupational Exposure Limits: No specific OSHA or ACGIH exposure limit set for zirconium nitrate. ACGIH TLV for insoluble zirconium compounds: 5 mg/m3 as Zr.
Engineering Controls: Use local exhaust ventilation to control dust. Handle only in chemical fume hood or enclosure for large-scale work.
Personal Protection: Chemical-resistant gloves (nitrile, PVC), safety goggles, face shield for large quantities, dust mask or NIOSH-approved respirator.
Environmental Controls: Avoid release to the environment. Use spill containment during handling.
Appearance: White to off-white hygroscopic solid or crystalline powder

Evaporation Rate: Not applicable
Chemical Stability: Stable under normal, dry, cool storage conditions. Decomposes at higher temperatures.
Reactivity: Reacts with reducing agents, organic materials, and combustibles—release of nitrogen oxides possible.
Possibility of Hazardous Reactions: Violent reactions with strong reducers. May ignite flammable materials.
Conditions to Avoid: Moisture, excess heat, flame, sparks.
Incompatible Materials: Alkali metals, hydrides, reducing agents, organic materials
Decomposition Products: Nitrogen oxides, zirconium oxide, toxic fumes.
Likely Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: May cause nausea, vomiting, headache, abdominal pain if swallowed. Mucous membrane irritation typical.
Skin Corrosion/Irritation: Causes redness, itching, soreness.
Serious Eye Damage/Irritation: Risk of eye burns, intense redness, tearing.
Respiratory Effects: Dusts cause coughing, sore throat, possible difficulty breathing.
Chronic Effects: Prolonged skin exposure may result in dermatitis. Chronic inhalation affects upper respiratory tract.
Carcinogenicity: Not classified by IARC, ACGIH, or NTP as a carcinogen.
Other Health Effects: Potential for allergic reactions in sensitive individuals. No evidence of specific organ toxicity.
Toxicity to Aquatic Life: May be harmful to aquatic organisms due to nitrate ions, which can contribute to eutrophication.
Persistence and Degradability: Inorganic compound; nitrate component persists in environment and moves with water.
Bioaccumulation: Not expected to bioaccumulate significantly.
Mobility in Soil: High water solubility means potential for leaching to groundwater.
Other Harmful Effects: Encourage proper containment to avoid run-off. Nitrate pollution linked to harmful algal blooms.
Avoid Release: Do not discharge into surface water, storm drains, or soils.
Waste Treatment Methods: Dissolve or mix material with a combustible solvent and burn in a chemical incinerator equipped with afterburner and scrubber.
Disposal of Containers: Rinse empty containers with water; dispose in accordance with governmental regulations.
Local Regulations: Observe all local, regional, and national/international environmental regulations.
Avoid Landfill: Do not place significant quantities in municipal waste streams or landfill. Hazardous waste pickup advised.
Waste Codes: Generate and use hazardous waste codes as dictated by local guidelines (e.g., US EPA RCRA).
