1. Introduction

Ethyl cyanoacetate is an important organic chemical raw material, widely used in medicine, pesticides, dyes and other fields. However, due to its toxicity, it may cause harm to the environment and human health. Therefore, strict compliance with relevant regulations is required to ensure safety during storage and transportation. This paper will discuss the safety storage and transportation specifications of ethyl cyanoacetate.

2. the physical and chemical properties of ethyl cyanoacetate

ethyl cyanoacetate is a colorless transparent liquid with pungent odor. Its molecular formula is C5H7NO2 and its molecular weight is 113.12. Ethyl cyanoacetate is insoluble in water, soluble in alcohol, ether and other organic solvents. It is stable to heat, but susceptible to hydrolysis under acidic and basic conditions.

3. the toxicity and harm of ethyl cyanoacetate

ethyl cyanoacetate is toxic to the human body, can enter the human body through inhalation, ingestion and skin contact, causing poisoning. Acute poisoning symptoms include headache, dizziness, nausea, vomiting, palpitations, chest tightness, etc., severe cases may appear coma, convulsions and other symptoms. Long-term exposure to ethyl cyanoacetate can cause damage to the nervous system, digestive system, and respiratory system.

4. of ethyl cyanoacetate safety storage specification

1. storage place should choose cool, ventilated, dry place, away from fire, heat source.
2. The storage container shall be a special container with good sealing performance to avoid leakage.
3. The storage area shall be provided with obvious safety warning signs, and smoking and open fire shall be prohibited.
4. Check the storage container regularly to ensure that it is intact.
5. Storage personnel should be professionally trained to understand the nature of ethyl cyanoacetate and safe operating procedures.

5. of ethyl cyanoacetate safety transport specification

1. transport vehicles should have the appropriate qualifications and certificates, transport personnel should be professionally trained.
2. Keep running smoothly during transportation to avoid severe vibration, collision and friction.
3. Special tanker or tanker shall be selected for the transport container to ensure good sealing performance.
4. Keep away from fire, high temperature and other dangerous factors during transportation.
5. In the process of transportation, the container and its accessories shall be checked regularly, and any abnormality shall be handled in time.
6. After the transportation, the transportation vehicles shall be cleaned and disinfected to prevent the residue from polluting the environment.

6. emergency treatment measures

1. In case of ethyl cyanoacetate leakage accident, the emergency plan shall be started immediately and effective measures shall be taken for disposal.
2. When the person is poisoned, the poisoned person shall be immediately moved to the ventilated place, and the first aid measures such as oxygen inhalation and cleaning shall be given.
3. In the event of a fire accident, fire fighting equipment such as dry powder and foam shall be used immediately, and the police shall be called for help.

7. conclusion

ethyl cyanoacetate as an important chemical raw material, in the process of storage and transportation need to strictly abide by the relevant norms to ensure safety. By understanding its physical and chemical properties, toxicity and hazards, as well as mastering the safety of storage and transportation standards, we can effectively prevent accidents and ensure the safety of personnel and the environment.
