The safety of mixed xylene storage and transportation specifications

1. Introduction

Mixed xylene is a common chemical production raw material, because of its unique physical and chemical properties, so that there are certain safety risks in the process of storage and transportation. In order to ensure the safe storage and transportation of mixed xylenes, it is very important to formulate a set of strict specifications and standards. This article will detail the safety storage and transportation specifications of mixed xylene to ensure safety in the production process.

2. the physical and chemical properties of mixed xylene

mixed xylene is a colorless and transparent, aromatic odor liquid, insoluble in water, miscible with alcohol, ether, acetone and other organic solvents. The steam and air can form an explosive mixture, fire, high heat caused by combustion explosion. Mixed xylene has an anesthetic effect on the central nervous system, and inhalation of high concentrations of mixed xylene can cause symptoms of poisoning.

3. safety storage specification

1. the storage place should be selected in a well-ventilated place away from fire and heat sources, and set up a special storage area to store separately from other chemicals.
2. The storage container shall be made of materials with good sealing performance and corrosion resistance, and shall be inspected and maintained regularly to ensure that the container is intact.
3. The storage site shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with possible safety accidents.
4. The storage of mixed xylene should be checked regularly to ensure accurate quantity and prevent safety accidents caused by misoperation.

4. safety transport specifications

1. transport vehicles should meet the relevant standards, with good sealing performance and anti-collision performance, to prevent leakage or collision accidents during transport.
2. The safety performance of the vehicle should be checked before transportation to ensure the normal operation of the vehicle during transportation and avoid safety accidents caused by vehicle failures.
3. During transportation, the vehicle speed should be kept stable, and operations such as sudden braking and sharp turns should be avoided to reduce safety risks during transportation.
4. In the process of transportation, professional escort personnel shall be equipped to monitor the whole process of transportation, and find and deal with possible safety problems in time.

5. emergency treatment measures

1. In case of mixed xylene leakage accident, the emergency treatment plan should be started immediately, the leakage source should be cut off, and special adsorption materials should be used to clean up the leakage.
2. In the event of a fire accident, fire extinguishers, foam and other fire extinguishing equipment shall be used immediately to extinguish the fire, and the police shall be called for help in time.
3. If any person is poisoned, the poisoned person should be immediately moved to a ventilated place, and necessary first aid measures, such as artificial respiration, heart compression, etc., should be given, and sent to the hospital for treatment in time.

6. training and education

1. Conduct regular safety training for personnel engaged in mixed xylene storage and transportation to improve their safety awareness and operation skills.
2. Carry out pre-job safety training for new employees to ensure that they understand the nature of mixed xylene and safe operating procedures.
3. Carry out regular safety drills to improve employees' ability to respond to emergencies.

7. supervision and inspection

1. Establish a sound regulatory system to comprehensively monitor the storage and transportation process of mixed xylene to ensure the implementation of norms and standards.
2. Regularly inspect and maintain storage and transportation facilities to ensure their safe and reliable operation.
3. Seriously deal with violations of norms and standards to prevent safety accidents.

8. conclusion

mixed xylene as a common chemical production raw material, there are certain safety risks in the process of storage and transportation. In order to ensure safety in the production process, strict specifications and standards must be formulated and strictly implemented. By taking safe storage and transportation measures, emergency treatment measures, training and education measures, the safety risks in the storage and transportation of mixed xylene can be effectively reduced to ensure production safety.
