Label Elements: Pictograms of flame over circle, skull and crossbones, corrosion
Hazard Statements: May cause fire or explosion; strong oxidizer. Toxic if swallowed, inhaled, or in contact with skin. Causes severe skin burns and eye damage. May cause respiratory irritation.
Signal Word: Danger
Precautionary Statements: Do not breathe dust or fumes. Keep away from heat, sparks, open flames, and hot surfaces. Store locked up. Wear protective gloves, eye protection, and protective clothing.
Potential Health Effects: Shortness of breath, burns to skin and eyes, nausea, convulsions. Possible chronic hazard with repeated exposure: symptoms such as cough and skin sensitization.
Chemical Name: Rhodium(III) Nitrate
CAS Number: 10489-46-0
Concentration: 99% or greater
Impurities: Trace metallic content depending on supplier
Inhalation: Move to fresh air, support breathing if necessary. Seek medical attention without delay for persistent symptoms like coughing, shortness of breath, or burning sensation.
Skin Contact: Remove contaminated clothing and flush skin with copious amounts of water for at least 15 minutes. If chemical burns persist, consult a doctor.
Eye Contact: Rinse cautiously with water for several minutes, removing contact lenses if present. Medical evaluation critical to prevent permanent damage.
Ingestion: Do not induce vomiting. Rinse mouth with water. Seek prompt medical care due to risk of systemic toxicity.
Advice to Physician: Treat as corrosive and toxic. Symptomatic and supportive care crucial, especially respiratory support and fluid management in severe cases.
Suitable Extinguishing Media: Use dry chemical, CO2, or water spray in large amounts. Avoid using dry combustibles.
Hazards Arising from Substance: Vigorous oxidizer; increases fire intensity. Decomposition liberates irritating and toxic gases such as nitrogen oxides and metal oxides.
Protective Equipment for Firefighters: Full turnout gear and self-contained breathing apparatus.
Special Precautions: Approach upwind. Keep containers cool using water spray to avoid rupture. Prevent run-off firewater from entering drains.
Personal Precautions: Limit access to area, ventilate well, and wear full chemical protective gear including nitrile gloves and eye protection.
Environmental Precautions: Prevent from reaching soil, waterways, and sewers.
Cleanup Procedures: Collect spillage with shovel into properly labeled containers. Wash down area with large quantities of water. Contaminated materials must be handled according to local hazardous waste guidelines.
Spill Reporting: Notify appropriate governmental authorities, especially if water contamination may occur.
Handling: Manage with caution using safety goggles, gloves, lab coat, and work in a chemical fume hood. Limit dust generation and avoid inhalation or skin contact. No eating, drinking, or smoking in work area.
Storage: Store in cool, dry, ventilated space away from combustibles, organic materials, acids, and bases. Containers must be corrosion-resistant, tightly closed, and clearly labeled. Use secondary containment to avoid leaks. Emergency wash stations and showers must be nearby.
Exposure Limits: No specific OSHA, ACGIH, or NIOSH exposure limits for rhodium nitrate; minimize exposure as much as possible.
Engineering Controls: Work inside a chemical fume hood to reduce airborne dust and fumes. Maintain eyewash stations and emergency showers near work zone.
Personal Protective Equipment: Nitrile or neoprene gloves, face shield or chemical goggles, lab coat or chemically resistant coveralls, and approved respirator where airborne concentrations may exceed safe limits.
General Hygiene: Wash hands thoroughly after handling. Remove contaminated clothing and launder before reuse.
Appearance: Yellow to orange-red crystalline solid
Odor: Sharp, pungent, nitric acid-like odor
pH: Acidic in aqueous solution
Melting Point: Decomposes before melting
Boiling Point: Decomposes before boiling
Solubility: Soluble in water
Density: Approximately 2.34 g/cm3
Vapor Pressure: Negligible at room temperature
Flash Point: Not applicable
Oxidizing Properties: Strong oxidizer, supports combustion
Chemical Stability: Stable under recommended storage conditions but decomposes on heating or in contact with reducing agents, producing toxic gases.
Reactivity: Reacts vigorously with organic material, reducing agents, and combustibles.
Incompatible Materials: Acids, strong bases, organic compounds, powdered metals, sulfides, and phosphides.
Hazardous Decomposition Products: Nitrogen oxides, metal oxides, toxic gases.
Acute Toxicity (Oral, Inhalation, Dermal): Highly toxic, can cause burning of mucous membranes, severe skin irritation, blisters, and respiratory distress. Ingestion may result in convulsions, vomiting, diarrhea, and potentially death from organ failure.
Chronic Effects: Repeated exposure may cause kidney and liver damage, sensitization, or respiratory tract damage. Data on carcinogenicity, mutagenicity, and reproductive toxicity are limited but caution is warranted.
Routes of Exposure: Inhalation, ingestion, skin and eye contact.
Symptoms of Overexposure: Shortness of breath, persistent cough, sore throat, skin rashes, and severe headache.
Aquatic Toxicity: Highly toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
Persistence and Degradability: Inorganic nitrate persists; rhodium component does not degrade naturally.
Bioaccumulative Potential: Rhodium does not significantly bioaccumulate but its compounds may persist in soil and sediments.
Mobility in Soil: Readily leaches into water systems due to solubility.
Other Adverse Effects: Potential for bioaccumulation in sediment-dwelling organisms and impact on microbial activity.
Methods of Disposal: Manage as hazardous waste according to local, regional, and national laws. Seek professional chemical waste disposal services. Do not dispose down the drain or into soil.
Container Disposal: Rinse empty containers with copious water and treat rinse as hazardous waste. Consult regulations for drum reconditioning or recycling, ensure all chemical traces are removed.
Precautions for Disposal: Prevent environmental release, avoid mixing with inflammable or incompatible waste streams.
