[Chemical Knowledge]：Storage mode and transportation specification of single substance

In the field of raw materials for chemical production, the safe storage and transportation of simple substances is very important. This article will elaborate on the basic concepts, classification, safe storage and transportation specifications of the single substance to ensure the safety of personnel and environmental protection during production and use. The basic concept and classification
of

1.
refers to pure substances composed of the same elements, such as hydrogen, oxygen, nitrogen, carbon, etc. In the production of chemical raw materials, elemental is usually used as an important basic raw material, widely used in various chemical reactions and processes.

According to the physical state and chemical properties of elemental, it can be divided into the following categories:

1. Metal elemental: such as sodium, potassium, iron, copper, etc., usually in solid state, with high activity.
2. Non-metallic elements: such as oxygen, hydrogen, nitrogen, chlorine, etc., may be gaseous, liquid or solid, with different chemical properties.
3. Rare gas: such as helium, neon, argon, etc., usually in a gaseous state, chemical stability.

2. safety storage specification

1. Storage facilities requirements: the single should be stored in a special warehouse or storage area, to ensure that the storage facilities dry, ventilated, sunscreen, fire. Different elements should be stored in partitions according to their properties to avoid contact with each other to cause chemical reactions.
2. Storage container requirements: storage containers that meet national standards should be selected to ensure good sealing, corrosion resistance and compression resistance. For flammable and explosive elements, explosion-proof containers should be used.
3. Storage environment requirements: The storage temperature, humidity and other environmental factors should be adjusted according to the nature of the single substance to ensure that the storage environment is suitable. For the simple substance that reacts with water, the warehouse should be dry; for the flammable and explosive simple substance, the warehouse should be cool and ventilated.
4. Storage identification requirements: clear identification shall be set up in the warehouse, indicating the name, danger, emergency measures and other information of the unit quality, so that personnel can quickly understand the unit quality attributes and response methods.
the safety of
3. transport specification

1. transport vehicle requirements: should be selected in line with national standards of professional transport vehicles, to ensure that the vehicle has sunscreen, rainproof, explosion-proof and other functions. For flammable and explosive substances, special dangerous goods transport vehicles should be used.
2. Transport packaging requirements: the single substance in the transport process should take appropriate packaging measures to ensure its stability and safety. Packaging should be tight, moisture-proof, shockproof, and marked with the name of the single substance, danger and other information.
3. Transportation personnel requirements: transportation personnel should have relevant qualifications and experience, understand the nature of the single substance and transportation requirements. In the process of transportation, we should be vigilant and take timely measures in case of emergencies.
4. Transportation route requirements: reasonable transportation routes should be selected to avoid passing through densely populated areas, important facilities and other sensitive areas. At the same time, the transportation route should be ensured to be unobstructed so that measures can be taken quickly in case of emergency.

4. case analysis
a chemical plant in
in the production and transportation process, due to not strictly abide by the safety storage and transportation norms, resulting in a serious safety accident. Accident investigation found that the factory in the storage and transportation of single substance there are the following problems:

1. Storage facilities do not meet the standards, there is no special single substance storage area, different single substance mixed, easy to cause chemical reaction.
2. The transport vehicle does not have the qualification for the transport of dangerous goods, and no effective protective measures are taken during the transport.
3. The transportation personnel lack relevant qualifications and experience, and do not understand the nature and transportation requirements of the single substance.

In response to the above problems, the plant has taken the following improvement measures:

1. Strengthen the construction of storage facilities, set up a special single quality storage area, and classify and store different single quality.
2. Use professional dangerous goods transport vehicles for transportation, and strengthen the protective measures during transportation.
3. Train transportation personnel to improve their qualifications and experience to ensure safety during transportation.

Through the implementation of the above improvement measures, the plant has successfully improved the safety of storage and transportation of single products and reduced the risk of safety accidents.

5. summary and recommendations

In the field of chemical production raw materials, the safe storage and transportation of simple substances is very important to ensure personnel safety and environmental protection. In order to ensure the safety of storage and transportation of single products, enterprises should strictly abide by relevant regulations and standards, strengthen the construction and management of storage facilities and transportation vehicles, and improve the safety awareness and technical level of personnel. At the same time, regular safety inspections and training are carried out to discover and solve potential safety hazards in time to ensure the safe and smooth progress of the storage and transportation process of single products.
