Composition / Information on Ingredients

Chemical Name: Triethylamine
Synonyms: N,N-Diethylethanamine; TEA
CAS Number: 121-44-8
Concentration: ≥99.0%
Impurities: May contain trace amounts of secondary and tertiary amines but usually within specification limits for safe and intended use.

First Aid Measures

Inhalation: Move to fresh air right away. Keep at rest. Get medical attention if you feel unwell or breathing trouble starts.
Skin Contact: Quickly remove contaminated clothing and rinse skin with water for at least 15 minutes. Seek medical care if irritation shows up.
Eye Contact: Rinse eyes carefully with water for at least 15 minutes; hold eyelids open. Contact a doctor for further treatment.
Ingestion: Rinse mouth without swallowing. Drink water if consciousness and condition allow. Don’t try to induce vomiting. Contact poison center or a doctor immediately.
Most Important Symptoms: Coughing, sore throat, burning sensations, redness, blisters, vision changes, stomach pain, drowsiness.
Notes for Doctors: Treat symptomatically. Ensure clear airway. Consider risk of laryngeal edema or bronchospasm.

Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, alcohol-resistant foam, CO2, water spray
Unsuitable Extinguishing Media: Direct water jet may spread fire
Hazardous Combustion Products: Toxic fumes (such as NOx, carbon oxides)
Advice for Firefighters: Wear self-contained breathing apparatus and full protective gear. Cool containers exposed to flames with water spray from safe distance.
Specific Hazards: Vapor may travel and ignite. Sealed containers risk explosion in fire or high heat.

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel. Keep people upwind. Wear appropriate protection including gloves, goggles, and respirators.
Environmental Precautions: Prevent run-off to drains, waterways, and soil.
Methods for Clean Up: Remove ignition sources. Use non-sparking tools to absorb spill onto inert materials like dry sand or earth. Transfer to closed chemical waste containers for disposal. Wash contaminated area with large amounts of water. Ensure ventilation.
Additional Advice: Notify authorities if spill enters environment, as required under local laws.

Handling and Storage

Precautions: Handle in a fume hood or well-ventilated area. Wear protective gloves, goggles, and chemical-resistant clothing. Keep away from flames, heat, static discharge, and incompatible substances.
Safe Storage: Store in tightly closed, clearly labeled containers in a cool, dry, well-ventilated area away from sunlight, food, acids, oxidizers, halogens. Use explosion-proof equipment for storage and transfer.
Incompatible Materials: Acidic substances, oxidizers, halogens; avoid contact with strong reducing agents.

Exposure Controls and Personal Protection

Exposure Limits: ACGIH TLV: 1 ppm (TWA), 3 ppm (STEL); OSHA PEL: 25 ppm (TWA)
Engineering Controls: Use local exhaust ventilation and enclosed processes. Clearly marked eye-wash stations and safety showers should always be close by.
Personal Protective Equipment: Always wear chemical splash goggles and face shield. Choose gloves of nitrile or neoprene rubber. Use flame-resistant lab coats or coveralls. Wear approved respirators (organic vapor type) if ventilation cannot control vapor levels.
Hygiene Measures: Never eat, drink, or smoke in areas where chemicals are handled. Wash up after handling. Remove contaminated clothing directly.

Stability and Reactivity

Chemical Stability: Stable under recommended storage conditions; not stable with improper handling or in contact with incompatible substances
Reactivity: Reacts with acids, oxidizers, and halogens to release dangerous vapors and heat
Hazardous Reactions: May form explosive mixtures with air; can generate heat and hazardous byproducts with strong acids

Toxicological Information

Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: LD50 (oral, rat): 730 mg/kg; LC50 (inhalation, rat, 4h): 7,000 mg/m3
Skin Corrosion/Irritation: Causes irritation, redness, possible blisters
Eye Damage/Irritation: Causes severe eye irritation, pain, redness, blurred vision, possible damage
Respiratory Effects: May cause cough, shortness of breath, chemical pneumonitis if inhaled
Chronic Effects: Prolonged exposure may affect liver, kidneys, nervous system, respiratory organs; sensitization rarely reported
Carcinogenicity/Mutagenicity/Reproductive Toxicity: No solid evidence for carcinogenicity in humans; no mutagenic or reproductive findings noted at occupational levels.

Ecological Information

Ecotoxicity: Toxic to aquatic life at high concentrations. LC50 (fish, 96h): 170 mg/L (Lepomis macrochirus)
