Chemical Name: 1,2-Ethylenediamine
Concentration: 99-100%
CAS Number: 107-15-3
Impurities/Additives: Minor water content (<1%), trace amines
Inhalation: Move exposed person to fresh air. If breathing has stopped, perform artificial respiration. Seek immediate medical attention.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with large amounts of water for at least 15 minutes. Get medical care. Wash clothes before reuse.
Eye Contact: Rinse eyes immediately with plenty of water, lifting upper and lower eyelids occasionally. Seek prompt medical care.
Ingestion: Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Obtain medical help immediately.
Acute Symptoms: Burning sensation, coughing, wheezing, headache, nausea
Delayed Effects: Blistering, corneal injury, severe respiratory tract irritation
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical, carbon dioxide
Specific Hazards: Vapors may form explosive mixtures with air. Heating can cause expansion or decomposition leading to violent rupture of containers.
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective gear.
Special Procedures: Fight fire from upwind. Cool containers with flooding quantities of water until well after fire is out. Avoid inhalation of toxic fumes.
Hazardous Combustion Products: Nitrogen oxides, ammonia, carbon monoxide, carbon dioxide
Personal Precautions: Evacuate unnecessary personnel. Provide adequate ventilation. Avoid breathing vapors and avoid contact with eyes, skin, and clothing. Eliminate ignition sources.
Environmental Precautions: Prevent spillage from entering drains, waterways, or soil. Alert authorities if product has caused environmental contamination.
Containment and Cleanup: Absorb with inert material (sand, vermiculite). Sweep up and place in suitable container for disposal. Ventilate area and wash spill site after material pickup.
Safe Handling: Handle with care. Use only in locations with proper ventilation. Avoid all contact with skin and eyes. Do not breathe vapor or mist.
Storage Requirements: Store in tightly closed containers in a cool, dry, well-ventilated place, away from sources of ignition, oxidizers, acids and moisture. Keep container upright and away from sunlight. Use explosion-proof electrical equipment.
Incompatible Materials: Strong oxidizers, acids, copper, brass, zinc, halogenated compounds
Transfer Precautions: Employ grounding and bonding to prevent static discharge.
Occupational Exposure Limits: ACGIH TLV: 10 ppm TWA (skin), OSHA PEL: 10 ppm TWA (25 mg/m³)
Engineering Controls: Mechanical ventilation, fume hood in laboratory settings, local exhaust
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), flame-retardant lab coat and pants, chemical splash goggles, face shield, respirator (NIOSH-approved if needed for vapor)
Hygiene: Wash thoroughly after handling; do not eat, drink, or smoke in work areas.
