GHS Classification: Eye Irritation (Category 2A); Specific Target Organ Toxicity – Single Exposure (Category 3, respiratory)
Hazard Statements: Causes serious eye irritation; May cause respiratory irritation
Pictograms: Exclamation mark symbol
Signal Word: Warning
Precautionary Statements: Wear eye protection, avoid inhaling dust, wash hands after handling, use only outdoors or in well-ventilated area
Potential Health Effects: Irritation to eyes, respiratory tract, and skin from direct contact or inhalation
Chemical Name: Sodium Carbonate
Common Name/Synonyms: Soda Ash, Washing Soda
Concentration: 98-100% by weight
Impurities: Varies depending on source; typically minimal
Eye Contact: Flush eyes thoroughly with water for at least 15 minutes, remove contact lenses if present and easily possible, seek medical attention for persistent irritation
Skin Contact: Wash skin with plenty of soap and water, remove contaminated clothing, seek medical advice if irritation develops
Inhalation: Move person to fresh air, get medical help if symptoms persist
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical attention if large amounts swallowed or discomfort occurs
Most Important Symptoms/Effects: Eye pain, redness, tearing, irritation of mucous membranes
Suitable Extinguishing Media: Use extinguishing agent suitable for the surrounding fire, such as water spray, dry chemical, carbon dioxide, or foam
Specific Hazards: Material itself does not burn but may decompose under intense heat to form sodium oxide and carbon dioxide
Protective Equipment: Firefighters should wear full protective gear including self-contained breathing apparatus
Further Advice: Avoid inhalation of dust or decomposition products, cool containers with water in case of fire nearby
Personal Precautions: Avoid generation and inhalation of dust, use suitable protective equipment (gloves, goggles, mask)
Environmental Precautions: Prevent entry to drains, surface or ground water
Cleanup Methods: Sweep up and shovel dry powder carefully, avoid creating dust, collect in suitable containers for proper disposal, ventilate area after cleanup
Other Advice: Wash down spill area with plenty of water
Safe Handling: Avoid eye and skin contact, minimize dust formation, handle in well-ventilated areas, do not eat, drink, or smoke during handling, wash hands thoroughly after use
Storage Conditions: Store in tightly closed, labeled containers made from compatible materials; keep dry and in a cool place away from acids
Incompatibilities: Strong acids, aluminum, fluorine, phosphorus pentoxide, strong oxidizing agents
Exposure Limits: Occupational exposure limits not established for sodium carbonate, use good industrial hygiene practices
Engineering Controls: Use local exhaust ventilation or general room ventilation
Respiratory Protection: Use dust mask or respirator if airborne dust exceeds exposure limits or irritates
Skin Protection: Wear suitable protective clothing, gloves
Eye Protection: Use chemical splash goggles or safety glasses with side shields
Hygiene Measures: Routine hand washing after handling, changing out of contaminated clothing promptly

Respiratory Effects: Dust inhalation can irritate nose, throat, lungs; coughing, sneezing common
Chronic Effects: Repeated or prolonged exposure may exacerbate existing respiratory or skin conditions
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, OSHA
Mutagenicity and Reproductive Toxicity: No evidence of significant effects
Ecotoxicity: Low aquatic toxicity at low concentrations; high pH from large spills can harm aquatic species
Persistence and Degradability: Inorganic salt; does not degrade but dissociates in water into ions
Bioaccumulative Potential: Does not bioaccumulate
Mobility in Soil: High mobility due to solubility in water; moves readily through soil and water
Other Effects: May contribute to an increase in alkalinity of surface waters, affecting aquatic organisms
