How to transport chemical raw materials safely

Dangerous goods are generally raw materials, intermediates and products of the chemical industry. The transportation method is mainly selected according to the physical and chemical properties of relevant products. If it is a production, trade or logistics enterprise, it needs to transport dangerous goods, First of all, there must be MSDS of the product (material data safety table), the products are divided into three states: solid liquid and gas. The solid state is generally only transported by railcar, and the gaseous state is only stored by pressure steel cylinder or pressure tank. The liquid products are transported flexibly. Because it has a great relationship with temperature, there are the following options for its transportation: generally barreled rear railcar with high viscosity or thermal insulation and heating tank car; steam pressure with viscosity close to water Small and non corrosive chemicals shall be transported by ordinary atmospheric tank truck; Corrosive products can be transported by stainless steel tanker.




Safe operation of common chemical raw materials

1、 Styrene



1. Storage: sealed and stored in a cool place. It is not recommended to store for a long time or in large quantities. The temperature of the stock shall be ≤ 30 ℃.



2. Precautions for operation: the closed operation shall be well ventilated, and the operator shall protect the parts directly and indirectly contacting styrene: the operator shall wear filter gas mask (half mask), chemical safety protective glasses, anti poison penetration work clothes and rubber oil resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Pay attention to handling with care during handling.



3, fire fighting means: fire extinguishing agent, foam, dry powder, carbon dioxide and sand. Fire extinguishing with water is invalid.



2、 Acetone



1. Storage: sealed and stored in a cool place, with the storage temperature ≤ 29 ℃.



2. Operation precautions: closed operation, good ventilation, reduce skin contact and inhalation of acetone. Operators wear filter gas masks (half masks), chemical safety glasses and butyl rubber gloves.



3, fire fighting means: fire extinguishing agent, anti foaming foam, dry powder, carbon dioxide and sand. Fire extinguishing with water is invalid.



3、 Industrial methyl ethyl ketone



1. Storage: methyl ethyl ketone shall not be exposed to the sun, isolated from fire, and the barrel shall be marked with flammable and toxic hazards.



2. Precautions for operation: closed operation and good ventilation. Smoking is strictly prohibited at the work site. Pay attention to personal hygiene. Avoid long-term repeated contact. If necessary, wear safety glasses, self-priming filter gas mask, anti-static work clothes and latex gloves.



3, fire fighting methods: anti foaming foam, dry powder, carbon dioxide and sand. Fire extinguishing with water is invalid.



4、 Acetylacetone



1. Storage: low temperature sealed storage, away from open fire or oxidant.



2. Precautions for operation: the closed operation shall be well ventilated, and there shall be no open fire at the work site. During operation, safety glasses, self-priming filter gas mask, anti-static work clothes and latex gloves shall be worn.



3, fire fighting means: fire extinguishing agent, fog water, foam, dry powder, carbon dioxide and sand. Firefighters must wear gas masks and full body fire suits to extinguish the fire in the upwind direction.
