Safety information of ethyl acetate
Ethyl acetate, also known as ethyl acetate, is a common organic compound. It is widely used in the chemical industry and plays an important role in many industries. However, it also has specific hazards, so it is crucial to clarify its safety information.

Physical and chemical properties
Ethyl acetate is a colorless and transparent liquid with a fragrant odor. Melting point is -83.6 ° C, boiling point is 77.2 ° C, relative density is 0.902 (water = 1), relative vapor density is 3.04 (air = 1). Slightly soluble in water, it can be miscible with most organic solvents such as alcohols, ethers, and chloroform.

Overview of Hazards
1. ** Health Hazards **: Inhalation of the vapor of this product can cause eye, nose and throat irritation symptoms. Inhalation at high concentrations can cause progressive anesthesia, acute pulmonary edema, liver and kidney damage. Continuous large-scale inhalation can cause respiratory paralysis. Those who take it by mistake can produce nausea, vomiting, abdominal pain, diarrhea, etc. It has sensitizing effect and causes bleeding gums due to vascular and nerve disorders; it can cause eczema-like dermatitis. Chronic Effects: Long-term exposure to this product can sometimes cause corneal opacity, secondary anemia, leukocytosis, etc.
2. ** Explosion Danger **: This product is flammable, irritating, and allergenic.

First Aid Measures
1. ** Skin Contact **: Remove contaminated clothing and rinse skin thoroughly with soapy water and clean water.
2. ** Eye Contact **: Lift eyelids and rinse with flowing water or normal saline. Seek medical attention.
3. ** Inhalation **: Quickly leave the scene to a fresh place with fresh air. Keep the respiratory tract unobstructed. If breathing difficulties, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
4. ** Ingestion **: Drink enough warm water to induce vomiting. Seek medical attention.

Fire-fighting measures
1. ** Hazardous characteristics **: Flammable, its vapor and air can form an explosive mixture. In case of open fire and high heat, it can cause combustion and explosion. Violent reaction in contact with oxidant. Its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of fire source, it will catch fire and backfire.
2. ** Harmful combustion products **: carbon monoxide, carbon dioxide.
3. ** Fire extinguishing method **: Use anti-soluble foam, carbon dioxide, dry powder, and sand to extinguish the fire. Water is ineffective for extinguishing the fire, but water can be used to keep the container in the fire site cool.

Emergency treatment for leakage
1. ** Emergency treatment **: Quickly evacuate the personnel in the leakage contaminated area to the safe area, and isolate them, strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-static overalls. Cut off the source of leakage as much as possible. Prevent flow into restricted spaces such as sewers and flood ditches.
2. ** Small amount of leakage **: Absorb with activated carbon or other inert materials. It can also be rinsed with a large amount of water. After the washing water is diluted, it is placed in the wastewater system.
3. ** Large amount of leakage **: Construct a dike or dig a pit for containment. Cover with foam to reduce vapor disasters. Transfer to a tanker or a special collector with an explosion-proof pump for recycling or transportation to a waste treatment site for disposal.

Operation Disposal and Storage
1. ** Operating Precautions **: Closed operation, full ventilation. Operators must be specially trained and strictly follow the operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), chemical safety protective glasses, anti-static 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 steam from leaking into the air of the workplace. Avoid contact with oxidants, acids, and alkalis. When filling, the flow rate should be controlled, and there should be a grounding device to prevent the accumulation of static electricity. When handling, it should be light and unloaded to prevent damage to packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may remain harmful substances.
2. ** Storage precautions **: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants, acids and alkalis, and should not be mixed. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to generating sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

Understand the safety information of ethyl acetate, and strictly follow the relevant procedures in the process of safe production, use and emergency treatment, which can effectively avoid accidents and ensure that personnel safety and the environment are not damaged.
