First Aid Measures

Eye Contact: Rinse with water for several minutes. Seek medical attention if irritation persists.
Skin Contact: Remove contaminated clothing. Rinse skin with water or shower. Get medical help if irritation occurs.
Inhalation: Move to fresh air and keep at rest. Call a physician if symptoms develop.
Ingestion: Rinse mouth. Do not induce vomiting. Contact a poison control center or doctor immediately.

Handling and Storage

Storage Conditions: Store in a tightly sealed container in a well-ventilated, cool, and dry area. Keep away from sources of ignition and incompatible materials.
Handling Precautions: Handle in a fume hood or with adequate ventilation. Avoid contact with skin and eyes. Use spark-proof tools and explosion-proof equipment.

Environmental Considerations

1,2-Dichloroethane is toxic to aquatic organisms and may contaminate groundwater due to its mobility in soil. Prevent any uncontrolled release to the environment. Dispose of waste according to local environmental regulations.
