GHS Classification: Not classified as hazardous under GHS standards
Signal Word: None required
Hazard Statements: May cause mild skin or eye irritation on prolonged or repeated exposure
Precautionary Statements: Avoid direct contact with eyes and skin, use proper handling techniques, wash hands thoroughly after handling
Routes of Exposure: Inhalation, ingestion, skin, and eye contact
Potential Health Effects: Dryness and transient discomfort in exposed areas, irritation to eyes and respiratory system if dust inhaled in large quantities
Chemical Name: Sodium Sulphate
Formula: Na2SO4
Concentration: >99% sodium sulphate, impurities typically <1%
Impurities: Trace amounts of water, sodium chloride or other sodium salts in technical grades
Inhalation: Move person to fresh air, keep at rest, obtain medical advice if symptoms of irritation or discomfort persist
Skin Contact: Rinse skin with water, remove contaminated clothing, wash affected area thoroughly with soap and water
Eye Contact: Flush eyes with running water for at least 15 minutes, keeping eyelids open, seek immediate medical attention if irritation occurs
Ingestion: Rinse mouth with water, do not induce vomiting, consult physician if large amounts swallowed or symptoms appear
Flammability: Non-flammable, does not support combustion
Suitable Extinguishing Media: Use fire extinguishing methods appropriate for surrounding fire, such as water spray, foam, carbon dioxide, or dry chemical
Specific Hazards: At extremely high temperatures, sodium sulphate may decompose, releasing toxic fumes such as sulfur oxides
Protective Equipment: Firefighters use standard protective gear and self-contained breathing apparatus to avoid inhalation of fumes
Special Information: Prevent contaminated runoff from entering drains or natural waters
Personal Precautions: Wear appropriate personal protective equipment including gloves, safety goggles, and dust mask
Environmental Precautions: Avoid discharge to stormwater, soil, or waterways
Spill Clean-up: Sweep up carefully, avoid creating dust clouds, place in closed containers for reuse or disposal
Decontamination: Wash spill area with water after removal of solid material, observe regulations for waste disposal
Handling: Use adequate ventilation, minimize dust formation, handle in accordance with good industrial hygiene practices, avoid unnecessary contact with skin and eyes
Storage: Store in sealed containers, keep in dry, cool, and well-ventilated area, avoid moisture exposure to reduce likelihood of caking or clumping
Incompatibilities: Strong acids, aluminum, magnesium, or other reactive metals on direct prolonged contact
Exposure Limits: No occupational exposure limits established for sodium sulphate
Engineering Controls: Ensure adequate mechanical or local exhaust ventilation in processing or bulk handling zones
Respiratory Protection: If airborne particles are generated, use dust masks compliant with regulatory standards
Skin Protection: Wear chemical-resistant gloves, long-sleeved clothing, and protective footwear
Eye Protection: Wear safety goggles or face shield where dust or solution splashes may occur
Hygiene Measures: Wash hands thoroughly before eating, drinking, or smoking, do not wear contaminated clothing

Flash Point: Not flammable
Chemical Stability: Stable under normal storage and handling conditions
Reactivity: Normally inert, may react with strong acids to produce toxic hydrogen sulfide gas, reacts thermally with aluminum and magnesium at elevated temperatures
Conditions to Avoid: Excessive heat, exposure to humidity, contact with acids or reducing agents
Hazardous Decomposition Products: Sulfur oxides may form under extreme heat or direct contact with acids
Acute Toxicity: Low oral toxicity, LD50 (oral, rat) > 5,000 mg/kg
Chronic Effects: No evidence of mutagenicity, carcinogenicity, or reproductive toxicity in humans
Skin and Eye Contact: May lead to mild irritation or dryness after repeated or prolonged exposure
Inhalation: Dust may cause minor respiratory irritation, especially for sensitive individuals
Ingestion: High doses may cause gastrointestinal upset such as nausea, vomiting, diarrhea
Environmental Fate: Sodium sulphate fully dissociates in water, largely mobile in soil and water
Toxicity to Aquatic Life: Low toxicity, LC50 (fish, 96-hour): 7,960 mg/L
Persistence and Degradability: Inorganic substance, not subject to biodegradation but considered readily dilute in large bodies of water
Bioaccumulation: Does not bioaccumulate
Effect on Plants and Animals: High concentrations may temporarily affect aquatic life if discharged directly into watercourses
Waste Disposal Methods: Dispose of material in accordance with federal, state, and local regulations, landfill or dissolve in excess water before disposal if permissible
Packaging Disposal: Rinse empty containers, recycle or dispose of as appropriate for material and container type
Precautions: Do not allow uncontrolled release to environment, keep out of drains and waterways, consult waste handler for acceptable disposal routes
