The safety of mixed benzene storage and transportation specification

1. Introduction

mixed benzene as an important raw material for chemical production, widely used in various fields. However, due to its unique chemical properties, mixed benzene has certain safety risks during storage and transportation. In order to ensure production safety and reduce the occurrence of mixed benzene leakage and fire accidents, it is very important to formulate a set of scientific and reasonable storage and transportation specifications for mixed benzene.

2. the nature and harm of mixed benzene

mixed benzene is a colorless, transparent, aromatic odor liquid, insoluble in water, miscible with a variety of organic solvents. Mixed benzene is toxic and flammable. Prolonged exposure or inhalation of mixed benzene vapor may cause human body poisoning, headache, nausea, vomiting and other symptoms, and even coma and death in severe cases. In addition, the mixed benzene also has a low flash point, flammable and explosive characteristics, once the leakage, easily lead to fire and explosion accidents.

3. mixed benzene storage specification

1. storage place should choose a cool, ventilated, dry place, away from fire, heat and power, avoid direct sunlight.
2. The storage container shall be a special container with corrosion resistance, pressure resistance and good sealing performance, and shall be inspected and maintained regularly to ensure that the container is intact.
3. The storage area shall be provided with obvious safety warning signs, and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
4. Keep the container airtight during storage to avoid leakage of mixed benzene vapor.

4. mixed benzene transport specification

1. transport vehicles should comply with the relevant standards, with fire, explosion, anti-static and other safety performance.
2. Before transportation, check the sealing performance of containers and vehicles to ensure that there is no leakage accident during transportation.
3. During transportation, stable driving should be maintained, and sudden braking, sharp turning and other operations should be avoided to reduce the shaking and impact of mixed benzene.
4. Keep away from fire, heat and open fire during transportation, and prohibit smoking and using mobile phones and other behaviors that are easy to cause fire.
5. After the transportation, the vehicle shall be cleaned and maintained to ensure the safety of the next transportation.
Emergency treatment
for
5. mixed benzene leakage
1. When mixed benzene leakage is found, the operation should be stopped immediately, the leakage source should be closed, and the fire source and power supply should be cut off.
2. Use special adsorption material to adsorb the leakage to avoid the diffusion of mixed benzene and environmental pollution.
3. For a small amount of leakage, non-combustible materials such as sand and dry lime can be used for covering treatment; for a large amount of leakage, special equipment should be used for recycling treatment.
4. Protective equipment shall be used during the treatment to avoid direct contact with mixed benzene vapor.

6. conclusion

mixed benzene as an important raw material for chemical production, there are certain safety risks in the process of storage and transportation. In order to ensure production safety and reduce the incidence of accidents, it is necessary to formulate strict storage and transportation specifications for mixed benzene, and strengthen the training and education of management and operators to ensure the effective implementation of the specifications. At the same time, a sound emergency plan and handling mechanism should be established to deal with a leakage accident quickly and effectively to ensure the safety of personnel and the environment.
