Inhalation: Remove the person to fresh air as quickly as possible. Seek medical attention if breathing becomes difficult or symptoms persist.
Skin Contact: Wash affected area thoroughly with soap and water. Remove contaminated clothing and launder before reuse. Get medical advice if irritation or symptoms develop.
Eye Contact: Flush eyes promptly with plenty of water for at least 15 minutes, lifting eyelids occasionally. Contact an ophthalmologist immediately.
Ingestion: Rinse mouth thoroughly. Do not induce vomiting. Seek medical advice promptly with details of the substance ingested.
Important Symptoms: Irritation or burning sensation in eyes, mouth, throat, and skin. Headache, dizziness, or gastrointestinal distress may occur after swallowing or inhaling dust.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, water spray, or alcohol-resistant foam
Unsuitable Extinguishing Media: Never use dry combustible materials as absorbent or extinguishing agents around oxidizers
Hazardous Combustion Products: May produce toxic nitrogen oxides and zinc oxides during decomposition.
Special Protective Equipment: Firefighters should use self-contained breathing apparatus and protective clothing. Stay upwind and avoid breathing vapors or dust.
Fire/Explosion Hazard: Substance increases fire risks by intensifying burning of combustibles. Remove nearby ignition sources and cool surrounding containers with flooding quantities of water.
Personal Precautions: Use respiratory protection and avoid contact with eyes and skin. Evacuate unnecessary personnel from the release area.
Environmental Precautions: Prevent entry into drains, sewers, basements, or waterways. Notify environmental authorities if contamination occurs.
Containment and Cleanup: Sweep up and place spilled material into clean, dry, and labeled containers using non-combustible absorbent. Ventilate area and wash spill site with water after cleanup.
Protective Equipment: Gloves, goggles, dust mask, chemical resistant boots, and coveralls recommended.
Handling: Use corrosion-resistant tools and containers. Wear proper personal protective equipment to reduce chance of accidental exposure. Always avoid generating dust and prevent contact with combustible materials.
Storage: Store away from organic, flammable, and easily oxidizable substances. Use cool, dry, and well-ventilated areas with corrosion-resistant shelves. Do not store in unlabeled containers or near food and drink.
Incompatible Materials: Keep away from strong acids, bases, combustible materials, reducing agents, and easily oxidizable metallic powders.
Other Notes: Regular inspection for container leaks or deterioration reduces risk.
Occupational Exposure Limits: Long-term (TWA) and short-term (STEL) exposure limits unavailable for zinc nitrate, but keep dust levels as low as practicable.
Engineering Controls: Use exhaust ventilation in workspaces where dust generation is likely. Isolate operations involving large amounts.
Personal Protection: Wear chemical splash goggles, face shield for risk of splashing, disposable gloves, and long-sleeved clothing. Respiratory protection, such as a NIOSH-approved dust mask or air-purifying respirator, should be considered in poorly ventilated spaces.
Hygiene Measures: Wash hands before breaks and after handling. Remove contaminated clothing before eating, drinking, or smoking.

pH: 4.5 – 6.0 (aqueous solution)
Melting Point: About 36°C (decomposes)
Boiling Point/Range: Decomposes before boiling
Flash Point: Not flammable
Evaporation Rate: Not applicable
Flammability: Not combustible but intensifies fire with other materials
Vapor Pressure: Negligible at room temperature
Vapor Density: Not applicable
Relative Density (Water = 1): 2.065
Solubility: Freely soluble in water
Partition Coefficient (n-octanol/water): Not established
Auto-ignition Temperature: Not applicable

Chemical Stability: Remains stable under ordinary temperatures and recommended storage conditions. Deliquescent nature causes cakes or clumps after moisture exposure.
Reactivity: Strong oxidizer; supports combustion of other substances.
Conditions to Avoid: Moisture, high temperatures, open flames, spark sources, and contact with powdered metals or other combustibles.
Incompatible Materials: Reducing agents, organic materials, strong acids or bases, finely divided metals.
Hazardous Decomposition Products: Nitrogen oxides and zinc oxide form after thermal decomposition.
Likely Routes of Exposure: Inhalation, ingestion, skin contact, eye contact
Acute Toxicity: Swallowing moderate amounts may cause abdominal pain, nausea, vomiting, and diarrhea. Inhalation can irritate respiratory tract.
Skin/Eye Damage: Causes redness, soreness, and possible burns. Eye exposure often results in severe irritation or conjunctivitis.
Chronic Effects: Prolonged exposure might lead to kidney or liver damage. No evidence of carcinogenicity found.
Sensitization: Not reported as a skin or respiratory sensitizer.
Specific Target Organ Toxicity: Data lacking, but repeated high level exposure could affect respiratory and digestive systems.
Aquatic Toxicity: Zinc nitrate hexahydrate proves toxic to aquatic organisms including algae, daphnia, and fish.
Persistence and Degradability: Dissolves rapidly in water, increases zinc and nitrate ion concentrations.
Bioaccumulative Potential: Zinc ions may bioaccumulate in aquatic life.
Mobility in Soil: Readily migrates with surface or groundwater.
Other Adverse Effects: Discharges to the environment can lead to oxygen depletion, altered nutrient cycles, and harm to sensitive aquatic habitats.
Safe Disposal Methods: Collect waste residue in clearly labeled, closed containers. Do not allow product to enter watercourses, soil, or sewers.
Disposal Guidance: Transfer hazardous material to a licensed chemical disposal facility according to local, regional, or national regulations.
Contaminated Packaging: Empty packaging must be handled as hazardous; do not reuse. Rinse thoroughly and follow disposal instructions for hazardous chemical containers.
Special Considerations: Consult environmental agency or local waste officials for appropriate handling of large spills.
