[Chemical Knowledge]：Specification for storage and transportation of alkali sulfide

The safety storage and transportation specification
of alkali sulfide in the field of chemical production raw materials
1. Introduction

alkali sulfide is an important chemical raw material, widely used in metallurgy, leather, dyes, medicine and other fields. However, due to its corrosiveness and toxicity, there is a greater safety risk in the storage and transportation of sulfide alkali. In order to ensure the safety and health of the staff, and to ensure the safety and control of the production and use of alkali sulfide, it is very important to formulate a specification on the safe storage and transportation of alkali sulfide.

2. the physical and chemical properties of alkali sulfide

alkali sulfide (Na2S) is a colorless or yellowish crystal or powder, with strong irritation and corrosion. It is soluble in water, the aqueous solution is alkaline, and acid reaction to generate the corresponding salts and hydrogen sulfide gas. Alkali sulfide has a corrosive effect on metals and has a strong stimulating effect on the skin, eyes and respiratory tract.

3. Sulfide Alkali Safety Storage Specification

1. The storage place should be dry, well-ventilated, away from fire and heat sources, and avoid direct sunlight.
2. Storage facilities should have anti-leakage, anti-seepage, anti-corrosion function, the ground should do anti-skid treatment.
3. Alkali sulfide should be stored separately from acidic substances, oxidants, combustibles, etc., and mixing is prohibited.
4. The storage area shall be provided with obvious safety warning signs and equipped with corresponding fire fighting equipment and emergency equipment.
5. Regularly inspect and maintain storage facilities to ensure that they are intact.

4. safety of sulfide alkali transport specifications

1. Transport vehicles should have the appropriate qualifications and certificates, drivers should be professionally trained and qualified.
2. During transportation, the stability of the goods should be ensured to prevent sliding and dumping, and at the same time avoid mixing with acidic substances, oxidants, combustibles, etc.
3. The transport vehicle shall be equipped with corresponding fire-fighting equipment and emergency equipment, and the driver shall be familiar with the emergency treatment measures.
4. During transportation, the road traffic safety regulations shall be complied with, the speed shall be kept stable, and operations such as sudden braking and sharp turning shall be avoided.
5. In the process of transportation, the goods should be closely monitored and abnormal situations should be handled in time.



1. In case of alkali sulfide leakage, start the emergency plan immediately and organize professionals to deal with it.
2. The handling personnel shall wear protective clothing, gloves, goggles and other personal protective equipment to avoid direct contact with alkali sulfide.
3. For small area leakage, it can be covered with sand, dry lime and other adsorption materials and collected, and then transported to the designated place for treatment. For large spills, special equipment should be used to recover or transport to wastewater treatment plants.
4. In the process of treatment, it is necessary to avoid leakage into sewers, rivers and other waters to avoid pollution to the environment.

6. Training and Education

1. Conduct regular safety training and education for staff engaged in the storage and transportation of alkali sulfide to improve their safety awareness and operational skills.
2. The training content shall include the nature, hazards, safety protection measures and emergency treatment measures of alkali sulfide.
3. Training forms can include classroom explanation, practical operation, case analysis and other ways.

7. supervision and inspection

1. Establish a sound supervision and inspection mechanism to regularly inspect and evaluate the storage and transportation process of sulfide alkali.
2. The inspection contents shall include the safety of storage facilities, the compliance of transportation vehicles, and the operation standardization of staff.
3. The problems found in the inspection shall be rectified in time to ensure the safety and control of the storage and transportation of the sulfide alkali.

In short, in order to ensure the safe storage and transportation of alkali sulfide in the field of chemical production raw materials, it is necessary to formulate strict specifications and strengthen supervision and inspection. Through training and education to improve the safety awareness and operation skills of staff, to ensure that the production and use of alkali sulfide process is safe and controllable, to provide a strong guarantee for the stable development of enterprises.
