In the field of chemical production raw materials, the safety of calcium carbonate storage and transportation specifications

1. Introduction

calcium carbonate as a common chemical production raw materials, widely used in plastics, rubber, coatings, building materials and other fields. However, improper operation during storage and transportation may lead to safety accidents. Therefore, in order to ensure the safe storage and transportation of calcium carbonate, it is essential to formulate this specification.

2. the physical and chemical properties of calcium carbonate

calcium carbonate is an inorganic compound with a white powdery appearance, odorless, and insoluble in water. Its chemical properties are stable, but it can be decomposed into calcium oxide and carbon dioxide under high temperature conditions. In addition, calcium carbonate has a high density and is prone to precipitation.

3. calcium carbonate storage specification

1. Storage place: should choose a dry, well-ventilated, cool place as the storage place, avoid direct sunlight and high temperature environment.
2. Storage container: A well-sealed container should be used for storage to prevent calcium carbonate from moisture and agglomeration. At the same time, the container should have corrosion resistance to avoid chemical reaction between the container and calcium carbonate.
3. Storage identification: obvious identification should be set up in the storage place, indicating the name, quantity, production date and other information of calcium carbonate, so as to facilitate management.

4. calcium carbonate transport specification

1. transport vehicles: should be selected with corrosion resistance, leak-proof performance of good transport vehicles for transport, to ensure that the transport process will not leak accidents.
2. Transport packaging: calcium carbonate should be packaged in bags with good sealing, and the net weight of each bag should comply with relevant national regulations. The packaging bag should be marked with the name, quantity, production date and other information of calcium carbonate.
3. Transportation route: A smooth and smooth transportation route should be selected to avoid driving on bumpy and tortuous routes to reduce the risk of damage to the packaging bag during transportation.
4. Transportation personnel: transportation personnel should be professionally trained and familiar with the transportation specifications and safety operation procedures of calcium carbonate to ensure safety during transportation.

safety measures for 5. calcium carbonate

1. during storage and transportation, calcium carbonate should be checked regularly to ensure that it is not affected with moisture, caking or deterioration.
2. For calcium carbonate that has been damp or caked, it should be dried or discarded to avoid the use of unqualified products.
3. The storage and transportation places shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with possible safety accidents.
4. For leakage accidents during transportation, corresponding measures shall be taken immediately to clean up and deal with them to avoid environmental pollution.

6. management supervision and training

1. Enterprises should establish and improve the management system of calcium carbonate storage and transportation, clarify the safety operation procedures and responsibility system, and ensure the effective implementation of various measures.
2. For calcium carbonate storage and transportation personnel, safety training and education should be carried out regularly to improve their safety awareness and operation skills.
3. Enterprises should regularly inspect and supervise the storage and transportation process of calcium carbonate, and promptly discover and rectify potential safety hazards to ensure the safety of the entire process.

7. conclusion

calcium carbonate as a common chemical production raw material, its safety storage and transportation is very important. Through the formulation and implementation of this specification, enterprises can ensure the safety of calcium carbonate during storage and transportation, reduce the risk of safety accidents, and ensure the smooth progress of production activities. At the same time, it is also conducive to protecting the environment and ensuring the health of employees, promoting the sustainable development of enterprises and the fulfillment of social responsibility.
