Safety of Acetonitrile Storage and Transportation Specifications

1. Introduction

Acetonitrile is an important chemical raw material, widely used in medicine, pesticides, plastics, fibers and other fields. However, acetonitrile has a certain toxicity and flammability, so strict compliance with relevant safety regulations is required during storage and transportation to ensure the safety of personnel and the environment. In this paper, the specification of safe storage and transportation of acetonitrile will be introduced in detail.

2. the properties and hazards of acetonitrile

Acetonitrile is a colorless transparent liquid with a special pungent odor. It is more toxic to the human body and can cause central nervous system inhibition, resulting in dizziness, headache, nausea, vomiting and other symptoms. At the same time, acetonitrile is also flammable, encountered flame, high heat or oxidant contact, may cause combustion explosion.

3. acetonitrile storage specification

1. storage place should choose a cool, ventilated, dry place, away from fire and heat sources.
2. The storage container shall be a special container with good sealing performance to avoid acetonitrile leakage.
3. The storage area shall be provided with obvious safety warning signs and equipped with corresponding fire fighting equipment.
4. During the storage process, the safety status of containers and storage areas should be checked regularly, and any abnormalities should be handled in time.

4. acetonitrile transport specification

1. transport vehicles should comply with the relevant safety standards, with fire, explosion, anti-static and other safety facilities.
2. Keep running smoothly during transportation to avoid severe vibration, collision and friction.
3. Transport personnel shall be professionally trained to understand the nature and hazards of acetonitrile and master emergency treatment measures.
4. The temperature and pressure of acetonitrile should be closely monitored during transportation, and any abnormality should be handled in time.

5. emergency treatment measures

1. skin contact: immediately take off contaminated clothing, rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
2. Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.
3. Inhalation: Quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
4. Ingestion: Drink plenty of warm water and induce vomiting. Gastric lavage with 1:5000 potassium permanganate or 5% sodium thiosulfate solution. Seek medical attention.

6. conclusion

acetonitrile as an important raw material for chemical production, its safety and storage and transportation regulations are very important to ensure the safety of personnel and the environment. Therefore, the relevant safety regulations should be strictly observed during storage and transportation, and regular safety inspections and maintenance should be carried out to ensure the safe and reliable storage and transportation of acetonitrile. At the same time, we should strengthen the training and exercise of emergency response measures, improve the ability to respond to emergencies, and ensure that effective measures can be taken quickly in emergency situations to minimize losses and impacts.
