In the field of raw materials for chemical production, the safe storage and transportation specifications
of silicon micropowder
1. Introduction

Silicon micropowder as an important raw material for chemical production is widely used in various industrial fields. However, due to its special physical and chemical properties, silicon powder has certain safety risks during storage and transportation. In order to ensure production safety and improve production efficiency, it is very important to formulate a set of strict storage and transportation specifications for silicon powder.

2. the properties and hazards of

silicon powder is mainly composed of crystalline silicon, which has the characteristics of high hardness and good chemical stability. However, due to its small particle size, it is easy to produce dust, which is harmful to the human body and the environment. Long-term exposure to silicon powder may lead to silicosis and other occupational diseases, at the same time, silicon powder may also cause fire or explosion and other safety accidents.

3. silicon powder storage specification

1. storage facilities: silicon powder should be stored in a dry, ventilated, fireproof special warehouse, avoid direct sunlight. The warehouse floor should be flat, non-slip, and equipped with fire-fighting facilities.
2. Storage container: Silica powder should be stored in a container with good sealing performance to prevent dust leakage. The container shall be clearly marked with the material name, hazard and storage precautions.
3. Storage management: A strict silicon powder storage management system should be established, and storage facilities should be inspected and maintained regularly to ensure storage safety. At the same time, staff should be given safety training to improve safety awareness.

4. silicon powder transport specifications

1. Transport vehicles: should choose to meet the requirements of special transport vehicles, to ensure that the vehicle has good sealing performance, to prevent leakage of silicon powder.
2. Transport packaging: silicon powder should be packaged with packaging materials that meet the requirements, and the packaging should be tight and firm to prevent damage during transportation.
3. Transportation routes: Reasonable transportation routes should be selected to avoid passing through densely populated areas and sensitive environmental areas.
4. Transportation personnel: professional training shall be conducted for transportation personnel to improve transportation safety awareness and operation skills.

5. emergency measures

1. Leakage treatment: in case of leakage of silicon powder, stop the operation immediately and take effective measures to clean up to avoid dust diffusion. At the same time, the leakage area should be ventilated to ensure that the air quality meets the standard.
2. Fire treatment: in case of fire, the emergency plan should be started immediately, fire extinguishers and other fire fighting equipment should be used to put out the fire, and the police should be called for help at the same time.
3. Medical rescue: If any person has discomfort symptoms after contact with silicon powder, he should be sent to the hospital for examination and treatment immediately.

6. supervision and management

In order to ensure the effective implementation of the storage and transportation norms of silicon powder, supervision and management should be strengthened. Relevant departments should regularly carry out special inspections on storage and transportation enterprises, and promptly rectify problems found to ensure safe production. At the same time, a sound reporting and reward mechanism should be established to encourage the public to participate in supervision and jointly maintain production safety.

7. conclusion

silicon powder as an important raw material for chemical production, its safe storage and transportation is very important. By formulating strict specifications and strengthening management and training, the safety risks of silicon powder during storage and transportation can be reduced to ensure the smooth progress of production safety.
