Inhalation: Move person to fresh air, monitor for any signs of respiratory distress, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin with soap and water for at least 15 minutes, if irritation develops consult physician
Eye Contact: Rinse cautiously with water for 15 to 20 minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical attention
Ingestion: Rinse mouth with water, do not induce vomiting, give water to dilute, get immediate medical help
Most Important Symptoms: Irritation to mucous membranes, burning of skin or eyes, possible headache or nausea
Notes to Physician: Treat symptomatically, monitor airway, consider risk of chemical pneumonitis if inhaled in large amounts
Suitable Extinguishing Media: Use CO2, dry chemical or foam, water spray for large fires
Special Hazards: Thermal decomposition may release irritating and toxic gases including sulfur oxides and carbon oxides
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear
Advice for Firefighters: Prevent runoff from entering drains, stay upwind to avoid gases and vapors, cool containers exposed to flames with water spray
Combustion Products: Carbon dioxide, carbon monoxide, sulfur dioxide, sulfur trioxide
Personal Precautions: Use appropriate personal protective equipment including chemical goggles, gloves, and splash-proof clothing, ensure adequate ventilation
Environmental Precautions: Prevent further leakage or spillage if safe to do, avoid discharge into the environment as sulfate compounds may be hazardous to aquatic life
Methods for Clean Up: Absorb with inert material such as dry sand or earth, scoop up and transfer to labeled container for disposal, ventilate area, wash affected surfaces with water and detergent
Precautions for Safe Handling: Use only in well-ventilated areas, avoid contact with skin, eyes, and clothing, prevent dust generation, practice good hygiene by washing hands and exposed skin after use
Conditions for Safe Storage: Store in cool, dry, well-ventilated location, keep tightly closed in original container, avoid moisture and incompatible substances such as strong bases and oxidizers, keep away from sources of ignition and direct sunlight
Incompatibilities: Avoid contact with strong acids, alkalis, and oxidizing agents, separation from food and feedstuffs advised
Engineering Controls: Use fume hood or local exhaust to minimize exposure, ensure eye wash station and safety shower are accessible
Personal Protection: Wear chemical-resistant gloves (such as nitrile), safety goggles or face shield, laboratory coat or apron, use NIOSH-approved respirator for dusty environments or insufficient ventilation
Exposure Limits: No specific occupational exposure limit established for this compound, general nuisance dust limits are 10 mg/m³ total dust, 3 mg/m³ respirable
