Impurities: Trace levels of nitrites, insoluble fragments, possibly dust, depending on storage and handling
Other Ingredients: No additional hazardous ingredients identified for pure reagent-grade material.
Inhalation: Move exposed person to fresh air. Keep person at rest and monitor for difficulty breathing or persistent coughing. Seek medical advice if symptoms such as throat irritation, headache, or dizziness develop.
Skin Contact: Immediately remove contaminated clothing and rinse skin thoroughly with running water. Wash affected skin with soap and water for at least 15 minutes. Seek medical attention if skin redness or irritation continues.
Eye Contact: Flush eyes cautiously with water for at least 15 minutes, holding eyelids apart. Remove contact lenses if possible and continue rinsing. Seek prompt medical advice if irritation persists or vision changes occur.
Ingestion: Rinse mouth thoroughly with water. Do not induce vomiting. Offer water to drink if the person is fully conscious. Get immediate medical help, especially if abdominal pain, nausea, or vomiting present.
General Notes: Ensure rescuers are wearing suitable protective equipment. Show this datasheet to attending physician.
Suitable Extinguishing Media: Use water spray, dry chemical, or carbon dioxide. Foam is typically less effective due to the oxidizing nature of the compound.
Unsuitable Extinguishing Media: Avoid dry combustible materials, as they may enhance fire due to oxidizing properties.
Specific Hazards: Decomposition can release toxic and irritating oxides of nitrogen. Supports combustion, may intensify existing fire.
Protective Equipment for Firefighters: Firefighters should wear chemical protective suits and self-contained breathing apparatus. Remove containers from fire area if possible without personal risk.
Special Advice: Cool exposed containers with water spray to prevent pressure build-up and possible explosion. Stay upwind, and keep unnecessary personnel away from the area.
Personal Precautions: Wear appropriate chemical resistant gloves, eye protection, protective clothing, and dust mask or respirator.
Spill Control: Avoid raising dust. Ventilate affected area. Evacuate non-essential personnel.
Containment: Prevent entry into drains, sewers, or watercourses. Use inert absorbent material, such as sand or earth, to contain and collect spilled product.
Cleanup Methods: Sweep up spilled material carefully and place in a labeled, suitable waste container for disposal in accordance with local regulations. Wash down contaminated area with plenty of water after material pickup.
Environmental Precautions: Report large spills to local authorities if release may cause environmental contamination or enter waterways.
Handling: Avoid contact with skin, eyes, and clothing. Do not breathe dust. Use in well-ventilated area, with proper local exhaust or chemical fume hood. Practice good hygiene; wash hands before eating or drinking, and after handling.
Incompatibilities: Keep away from reducing agents, organic materials, acids, powdered metals, alcohols, and easily combustible materials.
Storage: Store in tightly closed original container in a cool, dry, well-ventilated location, away from direct sunlight and incompatible substances. Separate from food, feed, combustibles and reducing agents.
Packaging: Use chemically resistant, labeled containers.
Occupational Exposure Limits: No specific exposure limits established for ferric nitrate nonahydrate by OSHA, ACGIH or NIOSH, though dust standards for particulates may apply. Sensible workplace practice limits dust exposure to lowest feasible level.
Engineering Controls: Work under chemical fume hood or ensure effective general and local exhaust ventilation to control airborne concentration.
Personal Protective Equipment:
• Respiratory Protection: Use NIOSH/MSHA-approved respirators if working conditions present a risk of inhaling dust or airborne concentrations approach nuisance limits.
• Skin Protection: Wear appropriate chemical-resistant gloves, such as nitrile or neoprene.
• Eye Protection: Use safety glasses with side shields or chemical splash goggles.
• Body Protection: Don lab coats or apron for laboratory and light industrial settings.
Hygiene Measures: Change out of contaminated clothing and launder before reuse.
Appearance: Pale to dark purple or reddish-brown crystalline solid
Odor: Odorless
Odor Threshold: Not applicable
pH (1% Solution): Strongly acidic, typically between 1.0 and 3.0
Melting Point/Freezing Point: 47.2°C (decomposes on melting, loses water of crystallization)
Boiling Point: Decomposes before boiling
Flash Point: Not flammable
Evaporation Rate: Not applicable
Flammability: Not combustible, acts as a strong oxidizer
Vapor Pressure: Negligible at room temperature
Vapor Density: Not applicable
Solubility: Highly soluble in water
Partition Coefficient (n-octanol/water): Not determined

Decomposition Temperature: Loses water and decomposes above 47°C, releasing nitrogen oxides
Viscosity: Not applicable
Other Data: Generates heat and acidic solutions upon dissolution in water.
Chemical Stability: Stable under proper handling and storage conditions; exposure to moisture or heat can cause loss of water of crystallization and decomposition.
Reactivity: Powerful oxidizer; reacts vigorously with organic or combustible material, reducing agents, strong acids, and bases.
Conditions to Avoid: Heat, moisture, static discharge, contact with incompatible materials.
Hazardous Decomposition Products: Nitrogen oxides (NO, NO2), toxic and irritating gases.
Hazardous Polymerization: Not known to polymerize.
Incompatible Materials: Reducing agents, organic substances, strong acids, bases, combustible materials, powdered metals.
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Acute Toxicity: Harmful if ingested; oral LD50 in rats varies, but typically reported in the range of 325 mg/kg (as ferric nitrate, anhydrous). May cause irritation of mucous membranes, gastrointestinal distress, vomiting, or diarrhea.
Skin Irritation: May cause redness, local irritation, or rash on prolonged exposure.
Eye Irritation: Contact leads to irritation, pain, redness, or severe damage in higher concentrations.
Chronic Effects: Repeated contact could produce skin sensitization or dermatitis. Long-term exposure to high levels may affect liver and kidneys.
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA for human exposure.
Mutagenicity and Reproductive Toxicity: Evidence for mutagenic or reproductive effects in humans not documented; studies remain limited.
Other Symptoms: Inhalation can irritate respiratory tract. Swallowing can cause severe abdominal pain, nausea, and possible tissue damage. Ingestion of large amounts could cause toxic iron overload.
Environmental Impact: Readily soluble iron nitrates can alter aquatic environments and support excessive growth of algae. Large discharges increase nitrate levels in water bodies, leading to eutrophication and potential harm to aquatic life.
Aquatic Toxicity: Toxic to some forms of aquatic organisms, fish, and invertebrates at elevated concentrations. Iron and nitrate ions are both regulated contaminants in drinking water sources.
Persistence and Degradability: Highly soluble and mobile in water; iron is naturally occurring but excess is an environmental concern.
Bioaccumulation Potential: Limited potential for bioaccumulation observed with iron; nitrate can bioaccumulate under certain conditions impacting aquatic species.
Mobility in Soil: Nitrate moves rapidly through soil, increasing risk of groundwater contamination.
Other Adverse Effects: Discharges into sewers or waterways should be avoided. Avoid spreading dust or solution on land or into storm drains.
Waste Disposal: Small amounts may be dissolved in large volume of water and neutralized following local regulations before disposal into chemical waste stream. Larger quantities should be managed as hazardous waste.
Container Disposal: Empty packaging thoroughly; rinse and treat rinsate as hazardous waste unless otherwise specified by regulations. Dispose of containers through an approved waste disposal contractor.
Regulatory Compliance: Follow state, federal, and local disposal regulations. Do not dispose of material in general waste, sewer, or environment.
Recommended Handling: Use chemical waste labels and clearly identify content for waste collection.
Reuse and Recycling: No established methods for reuse; avoid recycling contaminated packaging without verification and approval.
