Read： 506 Time：18months ago Source：Transform the World with Simplicity

D4 (dicyclohexadiene) is a common chemical raw material, widely used in synthetic rubber, plastic and resin fields. Due to its flammable and toxic properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article details the safe storage and transport specifications for D4. The physical and chemical properties of

1. D4

D4 is a colorless transparent liquid with pungent odor. Its molecular formula is C8H10 and its relative molecular mass is 106.17. D4 is insoluble in water, but is miscible with organic solvents such as alcohols and ethers. D4 has a low flash point, is flammable and toxic, and is harmful to the human body.

2. D4 safety storage specification

1. Storage site requirements: D4 should be stored in a cool, dry, well-ventilated special warehouse, away from fire, heat and direct sunlight. The warehouse floor shall be anti-skid and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
2. Storage container requirements: D4 should be stored in a special stainless steel or galvanized iron drum to ensure that the container is well sealed and prevent leakage. Containers shall be clearly marked with hazard identification and the name of the substance.
3. Storage limit requirements: According to relevant regulations, the storage capacity of D4 should be controlled within a certain range to avoid security risks caused by excessive storage.
4. Management requirements: Warehouse management personnel should undergo professional training, understand the physical and chemical properties of D4 and safety operation procedures, and conduct regular safety inspections and inspections.

3. D4 safety transport specification

1. transport vehicle requirements: D4 should use special dangerous goods transport vehicles for transport, vehicles should meet the relevant standards, with fire, explosion, anti-static and other safety facilities.
2. Transport packaging requirements: D4 transport packaging should meet national standards, with sufficient strength and sealing to prevent leakage and damage. The packaging shall be clearly marked with hazard identification and the name of the substance.
3. Transportation route requirements: safe transportation routes should be selected during transportation to avoid passing through densely populated areas and sensitive areas.
4. Requirements for transportation personnel: transportation personnel should be professionally trained to understand the physical and chemical properties of D4 and safe operation procedures, and have the ability to respond to emergencies.

4. Emergency Treatment Measures

During the storage and transportation of D4, in case of leakage, fire and other emergencies, the following emergency treatment measures shall be taken:

1. Leakage Treatment: In case of D4 leakage, the emergency plan shall be started immediately, effective measures shall be taken to control the leakage source, and special equipment shall be used to recycle the leaked materials. At the same time, the leakage area should be ventilated to avoid contact with personnel.
2. Fire treatment: in case of fire, fire-fighting equipment shall be used immediately to extinguish the fire, alarm and start the emergency plan at the same time. Keep a safe distance during fire fighting to avoid casualties.

In short, D4, as a common raw material for chemical production, must strictly abide by relevant regulations during storage and transportation to ensure safety. By strengthening the training of management personnel and transportation personnel, improving safety awareness and operational skills, safety risks can be effectively reduced and the safety of people's lives and property can be guaranteed.
