chemical production of raw materials for the safe storage and transport
of acetic anhydride
1. introduction

acetic anhydride is an important chemical production of raw materials, widely used in medicine, pesticides, plastics, dyes and other industries. However, due to its unique chemical properties, acetic anhydride has certain safety risks during storage and transportation. In order to ensure the safe storage and transportation of acetic anhydride, it is very important to formulate a set of strict specifications and standards.

2. the properties and hazards of acetic anhydride

acetic anhydride is a colorless transparent liquid, irritating and corrosive. It has a strong irritating effect on the skin, eyes and respiratory tract, and can cause chemical pneumonia and pulmonary edema. Prolonged exposure can cause skin degreasing and dermatitis. Acetic anhydride is also flammable and can cause combustion and explosion in case of open flame and high heat.
Safety storage specifications for
3. acetic anhydride

1. Storage facilities should be built in a cool, well-ventilated, dry place, away from fire and heat sources.
2. Storage containers should use special stainless steel or glass steel containers, avoid the use of iron, aluminum and other metal containers.
3. The storage area shall be provided with leakage emergency treatment equipment and suitable fire protection equipment.
4. Safety warning signs shall be set up in the storage area, and smoking and open fire shall be prohibited.
5. Regularly inspect and maintain storage facilities to ensure their safety and reliability.

4. acetic anhydride safety transport specification

1. transport vehicles should meet the transport requirements of dangerous goods, with the corresponding fire prevention, leakage prevention measures.
2. During transportation, it should be stable and avoid direct sunlight and high temperature environment.
3. During transportation, traffic rules shall be strictly observed to avoid illegal acts such as speeding and overloading.
4. Transportation personnel should be professionally trained and familiar with the properties of acetic anhydride and transportation safety knowledge.
5. During transportation, leakage emergency treatment equipment and appropriate fire prevention equipment shall be provided.

5. Acetic Anhydride Leakage Emergency Treatment

1. When acetic anhydride leakage is found, the operation should be stopped immediately and the leakage source should be closed.
2. Use sand or other non-combustible adsorbent to mix and absorb the leakage, and then collect it into a special container.
3. In case of a large amount of leakage, embankments or pits shall be constructed and covered with foam to reduce steam disasters.
4. Ventilate the leakage area to ensure air circulation.
5. In case of combustion, dry powder and carbon dioxide fire extinguishers shall be used to extinguish the fire. Water is prohibited.

6. training and education

1 for the storage and transportation of acetic anhydride staff on a regular basis safety training and education, improve their safety awareness and operational skills.
2. The training content includes the properties, hazards, safe storage and transportation specifications, and emergency treatment of leakage of acetic anhydride.
3. Improve the staff's ability to deal with emergencies through practical exercises.

7. supervision and inspection

1. Establish a sound acetic anhydride storage and transportation supervision system, and clarify the responsibilities and division of labor of various departments.
2. Regular inspection and maintenance of storage and transportation facilities to ensure compliance with safety standards.
3. Supervise and instruct staff in their operations to ensure that they comply with safety regulations.
4. Seriously deal with violations of safety regulations to prevent safety accidents.

8. conclusion

acetic anhydride as an important raw material for chemical production, its safe storage and transportation is of great significance to ensure production safety and personnel health. By formulating strict standards, strengthening staff training and education, and establishing a sound regulatory system, the safety risks in the storage and transportation of acetic anhydride can be effectively reduced, and the production safety of enterprises and the health of employees can be guaranteed.
