Emergency Contact: National Poison Control Center, Emergency Response center for industrial chemical spills or exposure events
Classification: Not classified as hazardous according to GHS standards, but considered an irritant at high concentrations
Hazard Statements: Causes mild skin and eye irritation upon significant exposure, inhalation of dust may irritate respiratory pathways
Precautionary Statements: Avoid inhaling dust, prevent contact with eyes and prolonged contact with skin, do not ingest
Signal Word: Warning
Symbol: No mandatory hazard symbol, but the exclamation mark represents irritation potential
Potential Health Effects: Eye irritation, respiratory discomfort, mild skin redness, possible gastrointestinal discomfort after ingestion
Chemical Name: Sodium Acetate Anhydrous
Purity: 99% minimum, with trace contaminants such as water and sodium carbonate typically under 1%
Synonyms: Acetic acid sodium salt, sodium ethanoate
Molecular Weight: 82.03 g/mol
Impurities: Sub-ppm levels of heavy metals, negligible biological contaminants under controlled storage conditions
General Advice: Move exposed person to fresh air in cases of inhalation; seek medical attention if symptoms persist
Inhalation: Remove to fresh air, provide water to rinse mouth and clear throat, consult a physician if breathing difficulties or irritation last more than one hour
Skin Contact: Wash skin thoroughly with soap and water, remove contaminated clothing and wash, seek further care if redness or discomfort continues
Eye Contact: Flush immediately with plenty of clean water for at least fifteen minutes, seek medical help after significant or persistent irritation
Ingestion: Rinse mouth, do not induce vomiting unless directed by medical personnel, seek immediate attention after large ingestions and document amount
Note to Physicians: Treatment remains symptomatic and supportive, monitor airway and hydration, avoid unnecessary invasive procedures
Suitable Extinguishing Media: Dry chemical, foam, water spray, or carbon dioxide—avoid direct high-pressure streams that may spread chemical dust
Hazardous Combustion Products: Breathing smoke from a fire involving sodium acetate presents risk of inhaling irritating fumes; possible acetic acid vapors and carbon oxides
Specific Fire Hazards: Material itself does not burn but may contribute to fire intensity if containers rupture or powder disperses
Advice for Firefighters: Wear self-contained breathing apparatus, full protective clothing in case of large fires with poor ventilation
Explosion Data: No risk of explosive reaction under normal handling, but containers can burst in intense heat
Personal Precautions: Use dust mask or particulate respirator, chemical-resistant gloves, and safety goggles, avoid raising dust during cleanup
Environmental Precautions: Prevent unchecked discharge into drains or water courses, sweep up dry powder for collection, contain any large spill using absorbent materials
Methods for Cleaning Up: Sweep or scoop spilled material into appropriate waste containers, ventilate area, wash down residue with plenty of water, dispose in compliance with regulations
Notification Procedures: Inform supervisor on duty and record the incident, follow workplace-specific reporting lines
Safe Handling Practices: Handle using tools and gloves, avoid creating dust clouds, never eat, drink, or smoke during use, always follow routine hygiene
Storage Conditions: Store in tightly closed containers kept in cool, dry, well-ventilated place, away from incompatible substances like strong acids
Incompatibilities: Avoid contact with acids, strong oxidizing agents, or materials sensitive to sodium ions
Special Storage: Avoid humidity as sodium acetate anhydrous absorbs moisture; use desiccators for long-term storage
Shelf Life: Quality remains consistent for several years if shelf and handling rules are followed, routinely inspect for caking or discoloration
Occupational Exposure Limits: No OSHA or ACGIH exposure limits specified, though good industrial hygiene recommends minimizing inhalable airborne concentrations
Engineering Controls: Utilize local exhaust ventilation at points of dust generation, employ enclosed handling systems if available
Personal Protective Equipment (PPE): Use chemical splash goggles, nitrile or neoprene gloves, standard dust mask (N95 or P2), and laboratory coat
Additional Measures: Wash hands thoroughly post handling, keep work and eating spaces separated, launder work clothing frequently
Appearance: White, odorless crystalline powder or granules
Odor: Slightly acetic when moist, no noticeable smell in dry state
pH: 8.5-9 (5% aqueous solution)
Melting Point: 324°C
Boiling Point: Decomposes before boiling
Solubility in Water: Fully soluble; up to 119 g/100 mL at 20°C
Density: 1.528 g/cm³
Flash Point: Not applicable
Vapor Pressure: Negligible at ambient conditions
Other Data: Stable under standard ambient conditions, minimal dust generation with gentle handling
Chemical Stability: Remains stable under recommended conditions of storage and handling
Reactivity: Inert to most materials under neutral or mildly alkaline conditions
Conditions to Avoid: Excessive moisture, strong heat sources, contact with strong acids
Incompatible Materials: Strong oxidizers, mineral acids, and compounds prone to exothermic acid-base reactions
Hazardous Decomposition Products: May yield acetic acid fumes, sodium oxide if heated to decomposition
Acute Toxicity: LD50 (oral, rat): approximately 3530 mg/kg, considered low toxicity in humans at normal workplace exposure
Skin Irritation: Temporary redness and dryness possible with significant, repeated exposure; not considered a sensitizer
Eye Irritation: Temporary burning or watering, resolves with minimal intervention
Inhalation Effects: Nose, throat, and upper respiratory discomfort possible with heavy dust exposure, asthma rare but documentable
Long-term Effects: No evidence of carcinogenicity or mutagenicity, no reports of organ toxicity in repetitive occupational exposure
Chronic Toxicity: Regular monitoring of air quality in dusty environments reduces risk, good workplace hygiene crucial
Aquatic Toxicity: High water solubility, but low acute toxicity toward aquatic life, does not accumulate in organisms or sediment
Soil Mobility: Dissolves and disperses rapidly in moist soils, unlikely to persist in the environment
Biodegradability: Breaks down in water and soil to sodium and acetic acid ions, rapidly metabolized by soil microbes
Bioaccumulation: Not considered to bioaccumulate in animal or plant tissues
Other Effects: Large spills into small water courses may temporarily raise sodium content, but quickly diluted or washed through ecosystem
Waste Treatment Methods: Material can be dissolved and highly diluted before disposal into municipal sewer systems, if permitted by local regulations
Regulatory Requirements: Non-hazardous waste under normal US EPA and EU directivest, verify with local administrative bodies regarding landfill or sewage
Container Disposal: Rinse empty containers thoroughly before recycling or discarding, keep chemical residues out of personal-use plastics
Recommended Practice: Keep waste and rinsewater isolated from food and biological growth zones, log all stored and disposed quantities
UN Number: Not regulated as a dangerous good under UN, IMDG, or IATA rules for routine shipment
Proper Shipping Name: Sodium acetate anhydrous
Transport Hazard Class: Not classified as hazardous
Packing Group: None assigned
Special Precautions: Avoid container puncture or exposure to wet conditions during transit, seal drums or bags securely
