The safety storage and transportation specification
of refined naphthalene
1. Introduction

refined naphthalene is an important chemical production raw material, widely used in dyes, medicine, pesticides and other fields. However, due to the toxicity and flammability of refined naphthalene, strict compliance with relevant regulations is required during storage and transportation to ensure safety and reliability. This article will introduce the safety storage and transportation specifications of refined naphthalene.

2. physical and chemical properties of refined naphthalene

refined naphthalene is a white crystalline powder with a strong odor. It is insoluble in water, but easily soluble in organic solvents. Refined naphthalene has a high melting point of 80.5 ℃ and a boiling point of 217.9 ℃. In addition, refined naphthalene is also flammable and toxic, which is harmful to the human body.

3. Naphthalene storage specification

1. Storage place should choose dry, ventilated, cool place, avoid direct sunlight and high temperature.

2. The storage site should be equipped with professional storage equipment, such as storage tanks, storage barrels, etc., and ensure that the equipment has good sealing performance and fire and explosion-proof performance.

3. Refined naphthalene shall be classified and stored, and shall not be mixed with inflammable, explosive and corrosive materials.

4. The storage place shall be provided with obvious safety signs and warning signs, and equipped with corresponding fire-fighting equipment and first-aid drugs.

5. Regularly conduct security inspections on storage sites to ensure that storage devices and sites meet security requirements.

4. fine naphthalene transport specification

1. transport vehicles should comply with the relevant standards, with good sealing performance and fire, explosion-proof performance.

2. Before transportation, the safety condition of the vehicle should be checked to ensure that it meets the transportation requirements.

3. During transportation, the vehicle speed should be kept stable, and operations such as sudden braking and sharp turns should be avoided.

4. During transportation, the stability of the goods should be ensured to prevent accidents such as sliding and tilting.

5. During transportation, high temperature and open fire should be avoided to prevent the goods from burning and exploding.

6. After the transportation arrives at the destination, the cargo should be unloaded in time, and the vehicle should be cleaned and maintained.

5. Naphthalene safety operation specification

1. Operators should be professionally trained to understand the nature of Naphthalene and safety operation procedures.

2. Before operation, the safety conditions of the equipment and the site should be checked to ensure that the operation requirements are met.

3. Professional protective equipment, such as gloves and masks, shall be worn during operation.

4. Avoid contact with skin and eyes during operation. Rinse with water immediately if contact is not careful.

5. During operation, good ventilation should be maintained to prevent harmful gas concentration from exceeding the standard.

6. After the operation, the equipment and site should be cleaned and maintained to ensure the safety of the next use.

6. of refined naphthalene emergency disposal specification

1. In case of any accident during storage and transportation, the emergency plan should be started immediately, and personnel evacuation and rescue should be organized.

2. In case of fire or explosion, call the police immediately and carry out fire fighting and rescue work.

3. If any person is injured, he should be sent to the hospital immediately for treatment.

4. Block and protect the accident site, and cooperate with relevant departments to investigate and deal with it.

7. summary

refined naphthalene as an important chemical production raw material, in the process of storage and transportation need to strictly abide by the relevant norms to ensure safety and reliability. By understanding the physical and chemical properties of refined naphthalene and mastering its storage, transportation and safe operation specifications, accidents can be effectively prevented and controlled to ensure the safety of personnel and property.
