    Triethylamine, an organic compound, named as N,N-diethylethylamine, is a colorless and transparent liquid with a strong ammonia odor, which slightly fumes in the air. It is soluble in water, soluble in ethanol and ether. The aqueous solution is weakly alkaline. Flammable and explosive. Toxic and highly irritating. Industrially, it is mainly used as solvent, curing agent, catalyst, polymerization inhibitor, preservative, and synthetic dyes.
    Chemical properties
    Organic bases, and inorganic acids to form soluble salts.  It is flammable. Its vapor and air can form an explosive mixture, which can cause combustion and explosion when exposed to open flames and high heat energy. It can react with oxidants. Its vapor is heavier than air and can spread to a considerable distance at a lower place, and will ignite when it encounters a fire source. Corrosive.
    Storage and transportation method
    The warehouse is ventilated, low temperature and dry; stored separately from oxidants and acids
    Notes
    Dangerous
    Health hazards: It has a strong irritation to the respiratory tract, and can cause pulmonary edema and even death after inhalation. Oral corrosion of the mouth, esophagus and stomach. Eye and skin contact can cause chemical burns.
    Explosion hazard: The product is flammable and has strong irritation.
    First aid measures
    Skin contact: Take off contaminated clothing immediately and rinse with plenty of running water for at least 15 minutes. Seek medical attention.
    Eye contact: Lift the eyelid immediately, and rinse thoroughly with plenty of running water or normal saline for at least 15 minutes. Seek medical attention.
    Inhalation: quickly leave the scene to a place with fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
    Ingestion: Rinse mouth with water, drink milk or egg white. Seek medical attention.
    Fire-fighting measures
    Hazardous combustion products: carbon monoxide, carbon dioxide, nitrogen oxides.
    Fire fighting method: spray water to cool the container, and if possible, move the container from the fire scene to an open place.
    Extinguishing agent: alcohol-resistant foam, carbon dioxide, dry powder, sandy soil. Extinguishing with water is ineffective.
    Leak handling
    Emergency treatment: Quickly evacuate personnel from the contaminated area to a safe area, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency response personnel wear self-contained positive pressure respirators and anti-virus suits. Enter the scene from the upper wind. Cut off the source of leakage as much as possible. Prevent entry into restricted spaces such as sewers and flood drains.
    Small leakage: Use sand or other non-combustible materials to absorb or absorb. It can also be washed with a large amount of water, and the washing water is diluted and put into the waste water system.
    A large number of leaks: build a dike or dig a pit for storage. Cover with foam to reduce steam hazards. Spray water or foam to cool and dilute the steam to protect the on-site personnel. Use explosion-proof pump to transfer to tank truck or special collector, recycle or transport to waste disposal site for disposal.
    Disposal and storage
    Operation precautions: airtight operation, strengthen ventilation. Operators must undergo special training and strictly abide by the operating procedures. It is recommended that operators wear catheter-type gas masks, wear protective overalls and rubber oil-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent the vapor from leaking into the air in the workplace. Avoid contact with oxidants and acids. The flow rate of the filling should be controlled to prevent the accumulation of static electricity. When handling, load and unload with care to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
    Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. The packaging is required to be sealed and not in contact with air. It should be stored separately from oxidants and acids, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials.
