Signal Word: None mandated
Hazard Statements: May cause mild skin or eye irritation in sensitive individuals; inhalation of dust could irritate the respiratory tract
Pictograms: No mandatory hazard symbols
Precautionary Statements: Avoid breathing dust, wash hands thoroughly after handling, wear eye protection for bulk handling to reduce potential exposure
Component: Sodium Citrate
Concentration: ≥ 99% (by weight)
Other Ingredients: Minor water content, no other known significant impurities
Inhalation: Move to fresh air, consult a physician if symptoms such as coughing or throat irritation persist
Skin Contact: Remove contaminated clothing, wash affected skin with soap and water; seek medical advice if irritation continues
Eye Contact: Rinse cautiously with water for at least 15 minutes; remove contact lenses if present and easy; obtain medical help for ongoing discomfort
Ingestion: Rinse mouth, do not induce vomiting, drink water to dilute; seek medical attention if feeling unwell or in case of large quantities swallowed
Suitable Extinguishing Media: Water spray, foam, dry chemical powder, or carbon dioxide
Specific Hazards: Emits sodium oxides and carbon oxides under extreme heat
Protective Actions: Firefighters use self-contained breathing apparatus and complete protective clothing
Advice for Firefighters: Prevent runoff into waterways, use extinguishing agents appropriate for surrounding materials
Personal Precautions: Wear appropriate personal protective equipment including gloves, goggles, and dust mask
Environmental Precautions: Avoid dispersal of dust into air, prevent material entering drains or waterways
Clean-up Methods: Sweep up and place in a suitable container for disposal; avoid dust generation by damping material with water if necessary; ventilate area
Handling: Minimize dust generation and accumulation, use with adequate ventilation, avoid contact with skin and eyes, avoid inhaling dust
Storage: Store in a tightly sealed container in a cool, dry, well-ventilated place away from incompatible substances such as strong acids or oxidizers
Storage Conditions: Keep container dry to avoid caking or reaction with moisture
Exposure Limits: Not established for sodium citrate; observe general dust exposure regulations (e.g., ACGIH TLV for particulate not otherwise classified)
Engineering Controls: Use local exhaust ventilation or process enclosures to keep airborne levels below exposure limits
Personal Protective Equipment (PPE): Safety glasses with side shields, lab coat, rubber or nitrile gloves, dust mask or respirator if dust is significant
Hygiene Measures: Wash hands after handling, launder contaminated clothing before reuse, no eating or drinking around the material
Appearance: White, crystalline powder or granules
Odor: Odorless
pH: About 8 (5% solution at 25°C)
Melting Point: Decomposes above 300°C
Boiling Point: Not available (decomposes on heating)
Solubility: Easily soluble in water
Vapor Pressure: Negligible at room temperature
Relative Density: Approximately 1.7 g/cm³
Other Properties: Non-flammable, stable in normal atmospheric conditions, tastes mildly saline
Chemical Stability: Stable under normal temperatures and storage conditions
Reactivity: Unreactive under standard handling
Conditions to Avoid: Exposure to strong acids may induce decomposition
Hazardous Reactions: Contact with acids generates citric acid, may release carbon dioxide gas
Hazardous Decomposition Products: Sodium oxides and carbon oxides under fire or extreme heat
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Low toxicity; large ingestion may cause gastrointestinal upset (nausea, diarrhea)
Chronic Effects: No evidence of chronic toxicity under normal use; studies indicate sodium citrate does not cause cancer or reproductive harm
Irritation: Mild irritation to eyes and skin in case of prolonged or repeated contact
Other Effects: Asthmatics and hypersensitive individuals may experience respiratory symptoms if exposed to dust
Ecotoxicity: Not considered harmful to aquatic life or the environment at typical levels of release
Persistence and Degradability: Rapidly biodegrades in water, natural processes break down compound
Bioaccumulative Potential: Low, not expected to accumulate in organisms
Mobility in Soil: Highly soluble, may leach through soils to water
Other Adverse Effects: Inordinate release may cause localized pH changes, proper dilution dissipates effect
Disposal Methods: Dispose as non-hazardous chemical waste according to local, regional, and national regulations
Waste Packaging: Rinse containers thoroughly before recycling or discarding
Precautions: Do not allow large amounts to enter waterways or sewers without authorization, seek landfill or incineration for bulk disposals
UN Number: Not regulated as hazardous for transport
Transport Hazard Class: Not assigned
Packing Group: Not assigned
Special Precautions: Prevent package breakage and dust release during transport
Shipping Name: Sodium citrate
Inventory Listings: Listed on TSCA (USA), REACH (EU), DSL (Canada), AICS (Australia), and most major inventories
Labeling Requirements: Not subject to detailed hazard labeling under most regulatory regimes
Regulatory Status: Recognized as Generally Recognized as Safe (GRAS) by the FDA for use in food
Workplace Safety: AHERA, OSHA, and local regulations require good housekeeping, minimal exposure to dust, and personal protective equipment as appropriate
