Classification: Not classified as dangerous according to GHS
Health Hazards: May cause slight irritation to eyes and skin. Inhalation of fine dust may trigger respiratory irritation. Prolonged contact isn't recommended for sensitive individuals.
Environmental Hazards: Not considered hazardous for the environment. Large spills can alter pH of water bodies.
Label Elements: No pictogram required. Signal word: None. Hazard statement: None.
Other Hazards: Fine powder may form combustible dust concentrations in air.
Ingredient: Sodium Citrate
Concentration: 99–100%
Chemical Formula: C6H5Na3O7·2H2O
Impurities: Trace amounts of other sodium salts possible, negligible impact on hazards to health or environment.
Inhalation: Remove to fresh air. Provide oxygen if breathing is difficult. Seek assistance if irritation persists.
Skin Contact: Remove contaminated clothing. Wash skin with plenty of water. If redness or discomfort develops, get medical attention.
Eye Contact: Rinse eyes with water for at least fifteen minutes, lifting upper and lower lids. Remove contact lenses if present.
Ingestion: Rinse mouth thoroughly. Drink water to dilute. If discomfort continues, consult a doctor.
Most Important Symptoms: Mild irritation for sensitive individuals, rarely serious.
Advice for Medical Personnel: Treat according to symptoms. No specific antidote known.
Extinguishing Media: Water spray (fog), foam, dry chemical, carbon dioxide. Use what is appropriate for surrounding fire.
Special Hazards Arising: Sodium oxides and carbon oxides may form under intense heat.
Protective Equipment: Wear self-contained breathing apparatus. Use full protective gear.
Firefighting Procedures: Move containers from fire if safe. Cool containers with water spray to avoid pressure build-up.
Other Advice: Avoid inhaling fire fumes. Keep water runoff contained to prevent contamination of water sources.
Personal Precautions: Wear safety goggles, gloves, and dust mask to limit exposure. Isolate spill area.
Methods for Cleaning Up: Sweep up dry material carefully to avoid dust. Place in labelled waste container. Wash spill site with water.
Environmental Precautions: Prevent material from entering drains or waterways in quantity. Report large releases per regulatory requirements.
Other Advice: Use non-sparking tools. Ensure adequate ventilation in confined or low-lying areas.
Precautions for Safe Handling: Handle with care to prevent dust formation. Avoid breathing dust. Wash hands before eating, drinking, or smoking.
Conditions for Safe Storage: Store in tightly closed containers in cool, dry, and well-ventilated spaces. Keep away from moisture and incompatible substances like strong acids.
Incompatible Materials: Strong oxidizing agents, mineral acids.
Other Recommendations: Use good hygiene protocols. Do not reuse empty containers for food or drink.
Engineering Controls: Use local exhaust ventilation to minimize airborne dust. General room ventilation suffices for most tasks.
Respiratory Protection: For dusty conditions, use NIOSH-approved particulate respirator.
Eye Protection: Wear safety goggles or glasses with side shields.
Skin Protection: Wear chemical-resistant gloves (nitrile, PVC recommended). Long sleeves minimize risk.
Other Protection: Provide eye-wash stations and safety showers near work areas. Take extra care with long-term exposure scenarios.
Occupational Exposure Limits: No established U.S. OSHA or ACGIH limits. Use standard dust exposure guidelines (15 mg/m3 total dust, 5 mg/m3 respirable fraction as per OSHA PEL for nuisance dust).
