Eye Contact: Rinse cautiously with clean water for 15 minutes, keeping eyelids apart. Remove contact lenses if present and easy to do; continue rinsing.
Ingestion: Rinse mouth. Do not induce vomiting unless directed by a medical professional. Offer water to drink. Seek immediate medical assistance.
Key Symptoms: Headache, coughing, nausea, irritation of skin and eyes, burning sensation in lungs

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical powder, foam, alcohol-resistant foam, carbon dioxide (CO₂). Avoid using direct water jets.
Specific Hazards: Vapors form explosive mixtures with air. May emit toxic fumes of hydrogen chloride, phosgene, and other chlorinated compounds when heated or burned.
Firefighting Instructions: Evacuate area, approach fire with self-contained breathing apparatus, full protective gear. Prevent run-off from entering drains.
Special Equipment: Respiratory protection, chemical-resistant clothing, gloves
Unusual Fire Hazards: Containers may rupture due to pressure build-up, especially when exposed to extreme heat.

Accidental Release Measures

Personal Precautions: Shut off all ignition sources. Ventilate the area. Evacuate unnecessary personnel.
Protective Equipment: Wear chemical-resistant gloves, goggles, and a respirator approved for organic vapors.
Spill Response: Absorb with earth, sand, or other non-combustible absorbent. Collect in properly labeled containers for disposal.
Environmental Precautions: Avoid discharge to sewers, waterways, or soil. Notify environmental authorities if significant quantities enter the environment.
Decontamination: Wash the spill area with a suitable detergent, ventilate to remove remaining vapors.

Handling and Storage

Handling Precautions: Handle with local exhaust or adequate ventilation. Keep away from sources of ignition. Do not breathe vapor or mist. Avoid skin and eye contact.
Storage Conditions: Store in tightly sealed containers, away from light and incompatible materials such as strong oxidizers, acids, alkalis. Keep at room temperature, in a dry, cool, and well-ventilated location.
Specific Requirements: Do not store near food or beverages. Keep container upright and closed when not in use.
Incompatibilities: Strong oxidizers, reducing agents, acids, bases
Additional Safe Practices: Use spark-proof tools and explosion-proof equipment. Control static electricity.

Exposure Controls and Personal Protection

Permissible Exposure Limits: No specific OSHA or ACGIH exposure limits set for this compound; control exposures to minimize irritation.
Engineering Controls: Use fume hoods, local exhaust ventilation, explosion-proof ventilation systems.
Personal Protection: Protective gloves (nitrile, PVC), chemical splash goggles, face shield if splashing possible, lab coat, chemical-resistant apron
Respiratory Protection: Properly fitted respirator (NIOSH/MSHA approved) for organic chemicals if ventilation is inadequate.
Hygiene Practices: Wash hands thoroughly after handling. Avoid contact of clothing and skin. Remove contaminated clothing before eating or drinking.
Environmental Controls: Provide spill containment and prevent environmental release.
