[Chemical Knowledge]：Specification for storage and transport of dichloropropane

The safety of dichloropropane storage and transportation specifications

1. Introduction

dichloropropane is an important chemical production raw material, widely used in medicine, pesticides, spices and other fields. However, due to its toxicity and flammability, strict compliance with relevant regulations is required to ensure safety during storage and transportation. This article will detail the safety storage and transportation specifications for dichloropropane.

2. physical and chemical properties of dichloropropane

dichloropropane is a colorless transparent liquid with pungent odor. Its density is larger than water, insoluble in water, soluble in organic solvents. Dichloropropane is flammable and may cause combustion and explosion in case of open flame, high heat or contact with oxidant. Its vapor is heavier than air and can spread to a considerable distance at a lower point, and it will catch fire and backburn in case of a fire source. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion.

3. safety of dichloropropane storage specification

1. storage place should be cool, ventilated, away from fire, heat source. The warehouse temperature should not exceed 30 ℃. It should be stored separately from oxidants and edible chemicals, and mixed storage should not be allowed. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
2. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-priming filtering respirator (half mask), chemical safety goggles, anti-static overalls and rubber oil-resistant gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidizing agents. When filling, the flow rate should be controlled, and there is a grounding device to prevent static accumulation. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.

4. Dichloropropane Safety Transport Specification

1. Before transportation, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall, or damage. It is strictly prohibited to mix with acids, oxidants, food and food additives. During transportation, the transportation vehicles shall be equipped with corresponding types and quantities of fire-fighting equipment and leakage emergency treatment equipment. During transportation, it shall be protected from sun exposure, rain and high temperature. Road transportation shall be carried out according to the prescribed route, and do not stop in residential areas and densely populated areas.
2. railway transportation should be carried out in strict accordance with the Ministry of Railways "dangerous goods transport rules" in the dangerous goods loading table. The package shall be complete at the time of shipment and the loading shall be safe. During transportation, ensure that the container does not leak, collapse, fall or damage. It is strictly prohibited to mix with oxidants, edible chemicals, etc. Transportation vehicles shall be equipped with leakage emergency treatment equipment during transportation. During transportation, it shall be protected from sun exposure, rain and high temperature. Road transportation shall be carried out according to the prescribed route, and do not stop in residential areas and densely populated areas.
Emergency Treatment
for
5. Leakage
evacuate personnel from the contaminated area to the safety zone, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off the leak source as much as possible. Prevent from flowing into restricted spaces such as sewers and flood drainage ditches. Small amount of leakage: adsorption or absorption with sand or other non-combustible materials. Large leakage: build embankments or dig pits to contain. Cover with foam to reduce steam disasters. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

6. conclusion

dichloropropane as an important chemical raw material, its safe storage and transportation is very important. By strictly complying with relevant regulations and taking effective protective measures, the safety risks of dichloropropane during storage and transportation can be reduced, and the safety of people's lives and property can be guaranteed.
