Concentration (typical): ≥98.5%
Impurities: Trace amino acids, water, minor salts
Other Components: None considered hazardous, fully disclosed upon request
Inhalation: Move person to fresh air, rinse mouth with water, seek medical attention for ongoing symptoms
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and plenty of water, consult health provider if irritation persists
Eye Contact: Rinse eyes with water for at least 15 minutes, remove contact lenses, seek medical advice for persistent irritation
Ingestion: Rinse mouth, drink water, do not induce vomiting, get medical attention if feeling unwell or large amounts swallowed
Most Important Symptoms: Mild respiratory-mucous irritation, possible stomach discomfort after ingestion, rarely rash
Suitable Extinguishing Media: Use foam, dry powder, carbon dioxide, or water spray for small fires

Hazards from Combustion: Thermal decomposition may release nitrogen oxides, hydrochloric acid fumes, carbon monoxide
Protective Equipment: Firefighters use self-contained breathing apparatus and protective clothing
Special Procedures: Cool fire-exposed containers, avoid inhaling smoke, contain firewater runoff
Personal Precautions: Wear mask, gloves, goggles in case of dusty release
Environmental Precautions: Prevent large releases into waterways, inform authorities if necessary
Containment Methods: Sweep up spills, minimize dust generation, shovel into labeled containers for disposal or reuse
Cleaning Procedures: Vacuum or wet-brush residues, wash site with water
Disposal: Follow regulatory requirements for non-hazardous organics, consult waste carrier for large volumes
Precautions for Safe Handling: Prevent dust formation, avoid breathing particles, use with local exhaust, avoid eating or drinking around handling area
Hygienic Practices: Wash hands thoroughly after use, maintain clean work area
