Eye Contact: Rinse eyes cautiously with water for at least 15 minutes, keep eyelids open, seek immediate medical attention
Ingestion: Rinse mouth thoroughly, do not induce vomiting, give small amounts of water if conscious, obtain medical attention as a priority

Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, alcohol-resistant foam
Unsuitable Extinguishing Media: Water jets produce splatter, can spread corrosive material
Hazardous Combustion Products: Sulfur oxides, carbon monoxide, carbon dioxide
Special Protective Gear for Firefighters: Full protective clothing, self-contained breathing apparatus
Fire/Explosion Hazards: Vapors corrosive; thermal decomposition emits toxic fumes
Fire-Fighting Procedures: Avoid runoff from fire control into sewers; cool exposed containers with water spray

Accidental Release Measures

Personal Precautions: Wear acid-resistant clothing, gloves, splash goggles
Environmental Precautions: Prevent material from entering soil, ditches, waterways
Cleanup Methods: Neutralize with sodium bicarbonate or lime, absorb with inert material, collect in suitable waste containers for disposal
Ventilation: Use local exhaust or move spill outdoors
Decontamination: Wash contaminated surfaces with dilute sodium carbonate

Handling and Storage

Handling: Work under chemical fume hood or ventilated area, avoid dust formation, wear protective clothing, do not eat, drink, or smoke during use
Storage Conditions: Store in tightly closed containers corrosion-resistant, out of reach of incompatible substances (strong bases, metals, oxidizers), maintain in cool, dry location
Special Sensitivities: Hygroscopic, avoid exposure to moisture and extreme temperatures
Incompatibilities: Bases, amines, alcohols, active metals, water-reactive substances

Exposure Controls and Personal Protection

Engineering Controls: Chemical-resistant benches, fume extraction, splash barriers
Eye Protection: Safety goggles or face shield
Hand Protection: Butyl rubber or nitrile gloves preferred
Skin Protection: Acid-resistant lab coat, apron
Respiratory Protection: NIOSH-approved respirator if dust or vapor above threshold
Hygiene Measures: Wash hands before breaks and after work, remove contaminated clothing immediately
