The safe storage and transportation specification
of pyrolysis naphthalene fraction
1. Introduction

pyrolysis naphthalene fraction is a common chemical production raw material, because of its unique physical and chemical properties, there are certain safety risks in the process of storage and transportation. In order to ensure production safety and improve production efficiency, it is very important to develop a set of scientific and reasonable storage and transportation specifications for cracked naphthalene fractions. Properties of

2. cracked naphthalene fraction

cracked naphthalene fraction is a colorless or pale yellow transparent liquid with a special odor. It is not easily soluble in water, but can be miscible with many organic solvents. The cracked naphthalene fraction has a low flash point, is easy to burn, and belongs to flammable liquid. In addition, it is toxic and irritating to human skin and eyes.

3. storage specification

1. Storage facilities: The pyrolysis naphthalene fraction should be stored in a cool, dry, well-ventilated special warehouse. The warehouse shall be equipped with fire fighting facilities, and keep away from fire and heat sources.
2. Storage container: special container with corrosion resistance, pressure resistance and good sealing performance shall be used to store the pyrolysis naphthalene fraction. The container shall be inspected and maintained regularly to ensure that it is in good condition.
3. Storage limit: According to the actual production demand and warehouse conditions, set the storage limit reasonably to avoid the security risk caused by excessive storage.
4. Personnel management: Warehouse management personnel should be professionally trained to understand the nature and safe operation procedures of cracked naphthalene fractions. Personnel entering the warehouse shall wear protective articles, and it is forbidden to carry kindling.

4. transport specification

1. transport vehicles: special vehicles with dangerous goods transport qualification should be used for the transport of cracked naphthalene fraction. The vehicle shall be equipped with corresponding fire fighting equipment and protective articles.
2. Transport packaging: The cracked naphthalene fraction shall be transported in special packaging conforming to the regulations, and the packaging shall be tight and firm to prevent leakage.
3. Transportation route: A safe transportation route should be selected to avoid passing through densely populated areas, open fire areas and other areas with high safety risks.
4. Accompanied by personnel: professional personnel shall be accompanied during transportation to ensure transportation safety.

5. safety operating procedures

1. Operators should be professionally trained to understand the nature of the cracking of naphthalene fractions and safe operating procedures, wearing a full range of protective equipment.
2. Check the condition of storage containers and transport vehicles before operation to ensure that they are intact.
3. In the process of operation, the operating procedures should be strictly observed to avoid leakage, combustion and other safety accidents.
4. In case of leakage and other safety accidents, emergency measures shall be taken immediately and relevant departments shall be reported in time.

6. emergency measures

1. Leakage emergency treatment: in case of cracking naphthalene fraction leakage, the leakage source should be cut off immediately, and the leakage should be absorbed by sand, dry lime and other adsorption materials, and placed in a special container for treatment.
2. Fire emergency treatment: in case of fire, fire extinguishers, foam and other fire fighting equipment shall be used immediately to put out the fire, and alarm and start the emergency plan at the same time.
3. Emergency treatment of poisoning: if any person is poisoned, the poisoned person should be immediately moved to a well-ventilated place, contaminated clothes should be removed, skin or eyes should be washed with plenty of water, and medical treatment should be sent in time.

7. summary

cracking naphthalene fraction as a common chemical production raw material, there are certain safety risks in the process of storage and transportation. In order to ensure production safety and improve production efficiency, enterprises should formulate a set of scientific and reasonable specifications for the storage and transportation of cracked naphthalene fractions, and strengthen the safety training and education of employees to ensure the effective implementation of various safety measures.
