Safety Information of Ethyl Acetate

Ethyl acetate is an organic compound with unique properties and uses. Its safety-related matters are quite critical.

In terms of health hazards, this substance has irritating effects on the eyes, nose and throat. 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 cause nausea, vomiting, abdominal pain, diarrhea, etc. It has sensitizing effects, causing bleeding of the gums due to vascular and nerve disorders; it can cause eczema-like dermatitis.

In terms of explosion hazard, ethyl acetate is extremely flammable, irritating and allergenic.

For first aid measures, if the skin comes into contact, immediately remove the contaminated clothing and rinse the skin thoroughly with soapy water and water. If the eyes come into contact, lift the eyelids, rinse with flowing water or normal saline, and then seek medical attention. If inhaled, quickly leave the scene to a fresh place with fresh air to keep the respiratory tract unobstructed. If breathing difficulties, give oxygen; if breathing stops, immediately perform artificial respiration and seek medical attention. If ingested, drink enough warm water, induce vomiting and seek medical attention.

Regarding fire protection measures, ethyl acetate is flammable, and its vapor and air can form an explosive mixture. In case of open flame and high heat, it can cause combustion and explosion. Violent reaction in contact with oxidants. Its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of fire, it will catch fire and backfire. When extinguishing fire, anti-soluble foam, carbon dioxide, dry powder, and sand can be used. Water is ineffective for extinguishing fire.

In terms of emergency treatment for leaks, once a leak occurs, personnel in the leaked contaminated area should be quickly evacuated to a safe area and quarantined to strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure respirators and anti-static work clothes. Cut off the source of leakage as much as possible. Prevent it from flowing into restricted spaces such as sewers and flood ditches. Small leakage: absorb with activated carbon or other inert materials. It can also be rinsed with a lot of water, diluted with washing water, and placed into the wastewater system. Large leakage: build a dike or dig a pit for containment. Cover with foam to reduce vapor disasters. Transfer to a tanker or special collector with an explosion-proof pump, recycle or transport to a waste disposal site for disposal.

There are also important points in the operation of disposal and storage. When operating, it should be closed and fully ventilated. 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 in 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 lightly loaded and unloaded to prevent damage to packaging and containers. Equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. Harmful substances may remain in empty containers. Storage should be stored in a cool and ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30 ° C. 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. Prohibit the use of machinery and tools that are prone to sparks. Storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
