Safety of sodium metasilicate storage and transportation specifications

1. Introduction

sodium metasilicate is a common chemical production raw materials, widely used in washing, ceramics, glass, paper and other fields. Due to its special chemical properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure its safety. This article will detail the safe storage and transportation specifications for sodium metasilicate.

2. the nature of sodium metasilicate

sodium metasilicate is a white crystalline powder, with strong alkaline and corrosive. It can react violently with water, producing large amounts of heat and corrosive gases. In addition, sodium metasilicate is also hygroscopic, easy to absorb moisture in the air and deliquescence.

3. sodium metasilicate storage specifications

1. The storage place should choose a dry, cool, well-ventilated place, avoid direct sunlight and high temperature.
2. Special plastic or glass containers should be used for storage containers, and metal containers should be avoided to avoid corrosion.
3. During storage, the sealing of the container should be checked regularly to prevent deliquescence and deterioration.
4. Obvious safety signs and warning signs shall be set up in the storage area to prohibit open flames and smoking.

4. sodium metasilicate transportation specification

1. before transportation should check whether the packaging is intact, if there is any damage should be replaced in time.
2. During transportation, it should be loaded and unloaded lightly to avoid collision and friction to avoid fire or explosion.
3. Transportation vehicles shall be provided with corresponding anti-corrosion and fire prevention measures to ensure safety during transportation.
4. Avoid high temperature and direct sunlight during transportation, and maintain good ventilation.

5. sodium metasilicate safety operation specification

1. Operators should be professionally trained to understand the nature of sodium metasilicate and safety operation procedures.
2. Before operation, check the integrity of the equipment and containers, and replace them in time if they are damaged.
3. Wear protective clothing and gloves during operation to avoid direct contact with sodium metasilicate.
4. Obvious safety signs and warning signs shall be set up in the operation area, and open flames and smoking are prohibited.

6. sodium metasilicate emergency disposal measures

1. In case of leakage, immediately cut off the leakage source, absorb residual liquid with sand or other non-combustible materials, and send it to the waste treatment site.
2. In case of fire, immediately cut off the fire source, put out the fire with fire extinguishing equipment, and call the police for help.
3. In case of personnel poisoning, the poisoned person should be immediately moved to a safe area, first aid measures should be taken, and sent to the hospital for treatment in time.

7. conclusion

sodium metasilicate is a common raw material for chemical production, and its safe storage and transportation are very important. By understanding the nature of sodium metasilicate and safe operation procedures, strictly abide by the storage and transportation specifications, can effectively avoid the occurrence of safety accidents, to ensure the safety of personnel and the environment.
