Product Name: Sodium Iodide Chemical Formula: NaI CAS Number: 7681-82-5 Synonyms: Sodium monoiodide, NaI Recommended Use: Laboratory reagent, pharmaceutical, radiation detection Manufacturer/Supplier: [Supplier Information] Contact Information: [Phone number, email, address] Emergency Phone: [Emergency contact number]
GHS Classification: Eye irritation (Category 2A), Skin irritation (Category 2), Acute toxicity oral (Category 4) Signal Word: Warning Hazard Pictograms: Exclamation mark symbol Hazard Statements: Causes skin and eye irritation, harmful if swallowed, may cause respiratory irritation Precautionary Statements: Do not breathe dust or fumes, wash hands thoroughly after handling, avoid release to the environment Target Organs: Thyroid gland, eyes, skin, respiratory system
Chemical Name: Sodium Iodide Common Name: NaI Concentration: ≥99% Impurities: Slight traces of sodium chloride, sodium bromide Other Ingredients: None known with hazardous properties under GHS
Inhalation: Move person to fresh air, supply oxygen if breathing is difficult, seek medical attention if symptoms persist Skin Contact: Remove contaminated clothing, rinse skin immediately with plenty of water for at least 15 minutes, contact physician if irritation develops Eye Contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present and easy to do, seek medical advice if irritation persists Ingestion: Rinse mouth, do not induce vomiting, drink water if conscious, get immediate medical help
Suitable Extinguishing Media: Water spray, foam, CO2, dry chemical powder Unsuitable Media: No direct water jet on heated material Specific Hazards: Produces toxic fumes of iodine and sodium oxides if heated or burned Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear Firefighting Instructions: Use water spray to cool containers, avoid inhalation of gases, contain contaminated fire water
Personal Precautions: Use personal protective equipment, avoid dust formation, ventilate area Environmental Precautions: Prevent further leakage or spillage, do not let product enter drains Methods for Cleaning Up: Sweep up and shovel into suitable containers for disposal, use damp cloth or mop to minimize dust, wash spill area thoroughly Emergency Procedures: Evacuate area if large spill occurs, consult safety officer
Safe Handling: Handle in well-ventilated areas, avoid contact with skin, eyes, and clothing, wash hands after handling Storage Conditions: Store in tightly closed containers, keep in cool, dry, well-ventilated place, protect from light and moisture Incompatible Materials: Strong acids, strong oxidizing agents, heavy metals Storage Temperature: 15–30°C Special Considerations: Store away from food and beverages
Exposure Limit Values: No specific limit values for sodium iodide, use controls for particulate matter Engineering Controls: Provide adequate local exhaust ventilation, safety showers and eyewash stations Personal Protective Equipment (PPE): Nitrile or latex gloves, chemical splash goggles, lab coat, suitable respiratory protection if dust is present Hygiene Measures: Wash hands thoroughly after handling, do not eat, drink, or smoke during use
Appearance: White crystalline powder or granules Odor: Odorless pH: 6.5 – 8.5 (5% solution) Melting Point: 661°C Boiling Point: Decomposes before boiling Solubility in Water: 184 g/100 mL (20°C) Density: 3.67 g/cm³ Vapor Pressure: Not applicable Partition Coefficient: Not determined Evaporation Rate: Not applicable Flash Point: Not applicable Auto-ignition Temperature: Not flammable
Chemical Stability: Stable under recommended storage conditions Conditions to Avoid: Excessive heat, exposure to light and moisture, incompatible materials Incompatible Materials: Strong acids, strong oxidizers, alkali metals Hazardous Decomposition Products: Iodine, sodium oxides Reactivity: May react violently with strong acids and oxidizing agents
Routes of Exposure: Inhalation, ingestion, skin and eye contact Acute Toxicity: LD50 (oral, rat): 4340 mg/kg Chronic Effects: May affect thyroid function with prolonged exposure Symptoms of Exposure: Irritation to skin, eyes, mucous membranes; nausea, headache, gastrointestinal distress Sensitization: Not reported Carcinogenicity: Not classified as carcinogenic by IARC, NTP, OSHA Specific Target Organ Toxicity: Possible effects on thyroid gland
Aquatic Toxicity: May be harmful to aquatic life in high concentrations Persistence and Degradability: Dissociates to sodium and iodide ions in water Bioaccumulation Potential: Low, iodide typically does not concentrate in organisms Mobility in Soil: High, sodium iodide is readily soluble and migrates with water Other Ecological Effects: Large releases may disrupt local ecosystems by altering iodine balance
Waste Treatment Methods: Collect and transfer to a licensed chemical disposal facility Contaminated Packaging: Dispose of containers as hazardous waste, do not reuse Disposal Regulations: Dispose of contents in accordance with local, regional, and national regulations
UN Number: Not regulated as dangerous good UN Proper Shipping Name: Sodium Iodide Transport Hazard Class: Not classified Packing Group: Not classified Special Precautions: Keep container tightly sealed, protect from humidity during transport Labels Required: None required under GHS
TSCA (USA): Listed EINECS (EU): 231-679-3 REACH Regulation: Exempted or not classified OSHA Hazards: Irritant SARA Title III: Not listed as extremely hazardous California Proposition 65: Not listed WHMIS Classification (Canada): D2B (toxic material causing other toxic effects)
