Inhalation: Move to fresh air. Seek medical advice if symptoms develop like coughing, difficulty breathing, or chest pain.
Skin Contact: Remove contaminated clothing immediately. Rinse affected skin with plenty of water for at least 15 minutes. Seek medical attention for persistent irritation, blistering, or pain.
Eye Contact: Rinse cautiously with lukewarm water for at least 15 minutes, lifting lower and upper eyelids occasionally. Remove contact lenses if present. Immediate medical attention is crucial as severe damage can occur.
Ingestion: Do not induce vomiting. Rinse mouth with water only if person is fully conscious. Seek emergency medical help immediately. Monitor for signs of burns or allergic reaction.
Most Important Symptoms: Burning sensation, pain, redness, blistering, difficulty breathing.
Immediate Medical Attention and Special Treatment Needed: Symptomatic treatment only. No specific antidote exists.
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide. Use agents suitable for surrounding fire.
Special Hazards: Releases toxic fumes of hydrogen chloride, nitrogen oxides, and other decomposition products when heated.
Protective Equipment: Wear self-contained breathing apparatus and full protective clothing. Avoid inhalation of combustion products.
Firefighting Procedures: Evacuate area, cool containers with water spray to prevent pressure build-up.
Explosion Data: Not considered an explosion hazard, but containers may rupture when exposed to heat.
Personal Precautions: Put on gloves, goggles, and protective clothing before cleanup. Use respiratory protection if ventilation is inadequate.
Environmental Precautions: Prevent entry into drains, surface water, and soil. Contain spill to prevent environmental contamination.
Clean-up Methods: Absorb liquid with inert material (sand, earth, vermiculite) and place in labeled containers for disposal. Wash spill area with plenty of water. Ventilate confined areas.
Notification: Report major releases to local authorities as required.
Handling: Use only with adequate ventilation. Avoid contact with skin, eyes, and clothing. Do not breathe mist, vapors, or spray. Avoid handling near incompatible chemicals.
Storage Conditions: Store tightly closed in original container in a cool, dry, well-ventilated area away from direct sunlight, acids, oxidizers, and open flames.
Special Requirements: Keep out of reach of children. Restrict storage access to trained personnel.
Recommended Packaging Materials: Polyethylene, PVC, or glass. Avoid storing in metal containers.
Occupational Exposure Limits: No specific TLV, PEL, or OEL established. Minimize exposure to lowest practical levels.
Engineering Controls: Use local exhaust ventilation to reduce vapors and spray mist. Provide eyewash and safety shower in work area.
Personal Protective Equipment: Chemical-resistant gloves (e.g., nitrile, neoprene), goggles or face shield, laboratory coat or chemical apron, safety boots. Use approved respirator if airborne concentrations exceed recommended limits.
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling. Change contaminated clothing immediately.

Waste Disposal Methods: Dispose as hazardous waste in accordance with local, state, and federal regulations. Incineration is usually the preferred method.
Container Disposal: Triple rinse empty containers with water before recycling or disposal. Do not reuse containers for other purposes.
Disposal Precautions: Do not release into sewers or natural waterways. Spilled material must be contained and handled as hazardous waste, avoiding inhalation and skin contact during handling.
Regulatory Codes: Federal, state, and/or local regulations may require reporting of spills and disposal procedures similar to RCRA hazardous waste.
