How to transport chemical raw materials safely
Dangerous goods are generally raw materials, intermediates, and products in the chemical industry. The choice of transportation methods is mainly based on the physical and chemical properties of the related products. If it is a production, trade or logistics company that needs to transport dangerous goods, it must first Product MSDS (Material Data Safety Sheet), the product is divided into three states: solid, liquid and gas, solid state can only be transported by pallet trucks, and gaseous state can only be stored in pressure cylinders or pressure tanks. Liquid products are transported flexibly, because it is very dependent on temperature. For its transportation, there are the following options: general barreled rear pallet truck transportation with high viscosity or heat preservation and heating tank truck transportation; chemicals with viscosity close to water, low vapor pressure, and non-corrosive chemicals are transported by ordinary pressure tank trucks; yes Corrosive products can be transported in stainless steel tank trucks.
Safe operation of common chemical raw materials
1. Styrene
1. Storage: sealed and kept in a cool place. Long-term storage and large-scale storage are not recommended. The inventory temperature is ≤30°C.
2. Operation precautions: airtight operation is well ventilated. The operator should protect the parts directly and indirectly in contact with styrene: the operator wears a filter-type gas mask (half mask), chemical safety glasses, and wear protective overalls. Rubber oil resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Pay attention to handle with care during transportation.
3. Fire fighting method: fire extinguishing agent, foam, dry powder, carbon dioxide, sandy soil. Extinguishing with water is ineffective.
2. Acetone
1. Storage: sealed and kept in a cool, stock temperature ≤29℃.
2. Operation precautions: airtight operation is well ventilated, reducing skin contact with acetone and inhalation. Operators Operators wear filter-type gas masks (half masks), chemical safety glasses, and butyl rubber gloves.
3. Fire fighting method: fire extinguishing agent, alcohol-resistant foam, dry powder, carbon dioxide, sandy soil. Extinguishing with water is ineffective.
3. Industrial methyl ethyl ketone
1. Storage: Methyl ethyl ketone should not be exposed to the sun, isolated from fire, and there should be signs of flammability and toxic hazards on the barrel.
2. Operation precautions: It is strictly forbidden to smoke in the closed operation and well-ventilated work site. Pay attention to personal hygiene. Avoid long-term repeated contact. If necessary for work, you should wear safety glasses, self-absorption filter gas mask, anti-static overalls, and latex gloves.
3. Fire fighting methods: alcohol-resistant foam, dry powder, carbon dioxide, sandy soil. Extinguishing with water is ineffective.
Four, acetylacetone
1. Storage: Sealed and stored at low temperature, away from open flames or oxidants.
2. Operation precautions: The airtight operation is well ventilated, and there is no open flame at the work site. When working, you should wear safety glasses, self-absorption filter gas masks, anti-static overalls, and latex gloves.
3. Fire fighting method: fire extinguishing agent, water spray, foam, dry powder, carbon dioxide, sandy soil. Firefighters must wear gas masks and full-body firefighting suits to put out fires in the upwind direction.
