The safety of cumene storage and transportation specifications

1. Introduction

cumene is an important chemical production raw material, widely used in medicine, pesticides, spices and other fields. However, cumene has certain toxicity and flammability, so it is necessary to strictly abide by relevant regulations during storage and transportation to ensure safety. This article will detail the safety storage and transportation specifications of cumene.

2. the physical and chemical properties of cumene

cumene is a colorless transparent liquid with aromatic odor. Insoluble in water, miscible in ethanol, ether, acetone and other organic solvents. The steam and air can form an explosive mixture, fire, high heat caused by combustion explosion. Can react strongly with oxidants. Its steam is heavier than air, can spread to a considerable distance at a lower place, and will catch fire and ignite in case of fire source. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion.

3. cumene safety storage specification

1. The storage place should be selected in a well-ventilated place away from fire and heat sources, and set up fire-fighting equipment and leakage emergency treatment equipment.
2. The storage container shall comply with relevant national standards and be inspected and maintained regularly to ensure that it is in good condition.
3. Keep the container closed during storage to avoid leakage and volatilization of cumene.
4. Obvious safety warning signs shall be set up in the storage place, and smoking and open fire shall be prohibited.
5. Storage personnel should be professionally trained to understand the properties and safe operating procedures of cumene.

4. cumene safety transport specification

1. transport vehicles should comply with relevant national standards, with explosion-proof, fire prevention and other safety facilities.
2. Before transportation, check the tightness and integrity of the container to ensure that there will be no leakage during transportation.
3. Keep running smoothly during transportation to avoid severe vibration and collision.
4. Transport personnel should be professionally trained to understand the nature of cumene and safe operating procedures.
5. The transportation shall comply with relevant national laws and regulations and road transportation safety regulations.

5. cumene leakage emergency treatment specification

1. When cumene leakage is found, the operation should be stopped immediately, and the leakage source should be closed to prevent the leakage from spreading.
2. For a small amount of leakage, sand, dry lime or soda ash can be mixed and recycled to a special waste disposal site.
3. For a large number of leaks, embankments or pits should be built and covered 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.
4. The personnel shall evacuate the contaminated area to the safe area, isolate and strictly restrict the access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off leakage sources as much as possible to prevent them from flowing into restricted spaces such as sewers and flood discharge ditches. Small amount of leakage: adsorption or absorption with sand or other non-combustible materials. It can also be scrubbed with an emulsion made of a non-flammable dispersant, and the washing liquid is diluted and put into the waste water system. A large number of leaks: build a dam or dig a pit to accommodate; 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

cumene as an important chemical production raw material, in the process of storage and transportation need to strictly abide by the relevant norms to ensure safety. By understanding the physical and chemical properties of cumene, safety storage and transportation specifications and leakage emergency treatment specifications, we can effectively prevent the occurrence of safety accidents and ensure the safety of people's lives and property.
