Ethyl acetate material safety data table related matters

Ethyl acetate, also known as ethyl acetate, its material safety data table (Ethyl Acetate Material Safety Data Sheet) is essential to grasp the characteristics of the substance, safe operation and emergency response.

1. Chemical and corporate logo
Ethyl acetate, English name Ethyl Acetate. Manufacturers need to provide accurate contact information so that they can communicate quickly in emergencies or in case of doubts.

2. Composition/Composition Information
Ethyl acetate is mainly composed of ethyl acetate, and the chemical formula is $C_ {4} H_ {8} O_ {2} $. Usually pure, but industrial products may contain a small amount of impurities. It is necessary to clarify the type and content of impurities, because it may affect the properties and safety of the product.

III. Overview of Hazards
1. ** Physical and Chemical Hazards **: Ethyl acetate is flammable, and its vapor can be mixed with air to form an explosive mixture. In case of open flame and high heat can cause combustion and explosion, and react violently with oxidant contact.
2. ** Health Hazards **: Inhalation of this product's vapor has irritating effects on the nose and throat. Inhalation at high concentrations can cause progressive anesthesia, acute pulmonary edema, liver and kidney damage. Continuous inhalation in large quantities 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 of 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.

IV. First aid measures
