Eye Contact: Rinse immediately with plenty of water for several minutes; seek medical advice if irritation persists
Skin Contact: Wash with soap and water; remove contaminated clothing and launder before reuse
Inhalation: Move to fresh air; seek medical attention if symptoms: cough, sore throat, or shortness of breath develop
Ingestion: Rinse mouth with water; drink water to dilute; do not induce vomiting; get medical help if adverse effects appear
Most Important Symptoms: Redness, tearing, coughing, scratchy throat
Immediate/Delayed Effects: Irritation of eyes and airways; no delayed chronic effects reported at occupational exposures
Advice for Physicians: Treat symptomatically; no known specific antidote
Suitable Extinguishing Media: Use water spray, carbon dioxide, dry chemical, or foam for surrounding fires
Unsuitable Media: Not applicable (does not burn)
Special Hazards: Product does not support combustion; decomposes at extremely high temperatures into sodium oxide, which may react violently with water
Protective Equipment: Firefighters require self-contained breathing apparatus in case of dust or toxic decomposition fumes
Hazardous Combustion Products: None expected under normal conditions
Explosion Risk: No known risk under fire conditions
Special Instructions: Avoid stirring up dust; evacuate area if large amounts involved or if decomposition suspected
Personal Precautions: Wear dust mask or respirator, safety goggles, gloves to prevent contact
Environmental Precautions: Prevent entry into drains, waterways; notify authorities if large spill
Methods for Clean Up: Sweep or vacuum up material; place into suitable, clearly labeled container for recovery or disposal
Spill Handling: Minimize dust generation; use industrial vacuum with HEPA filter or dampen slightly for manual pick-up
Waste Disposal: Follow local, state, federal regulations; do not discharge into environment
Decontamination: Wash area with water after bulk removal
Reference to Section: Consult protective measures under Exposure Controls
Safe Handling: Use outdoors or in well-ventilated area, minimize dust and eye contact, avoid eating, drinking, or smoking near product
Handling Precautions: Wear proper personal protective equipment; keep containers closed when not in use
Storage Conditions: Store in dry, well-ventilated space, protected from moisture and incompatible materials (strong acids)
Incompatible Substances: Avoid acids (may generate heat and gases); do not store with oxidizers
Container Requirements: Use containers that seal tightly to prevent moisture entry
