ortho-xylene safety storage and transportation specification

1. introduction

ortho-xylene is a common chemical production raw materials, widely used in plastics, fiber, rubber and other fields of production. However, due to its flammable and toxic properties, o-xylene has certain safety risks during storage and transportation. Therefore, in order to ensure the safe storage and transportation of o-xylene, it is very important to formulate a set of standardized storage and transportation specifications.

2. physical and chemical properties of o-xylene

o-xylene is a colorless transparent liquid with aromatic flavor. It is not easily soluble in water, but it is miscible with organic solvents such as alcohol, ether, acetone, etc. Ortho-xylene has a low flash point, is easy to burn, and produces toxic smoke when burned. In addition, o-xylene is also toxic, and prolonged exposure or inhalation of its vapors may cause poisoning.

3. safety storage specifications for o-xylene

1. The storage place should choose a dry, ventilated and cool place to avoid direct sunlight and high temperature.
2. The storage container shall be a special storage tank with good sealing performance to avoid o-xylene leakage.
3. The storage site shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
4. During storage, the sealing performance and storage capacity of the storage tank should be checked regularly to ensure storage safety.

4. the safety of o-xylene transport norms

1. transport vehicles should have the appropriate qualifications and certificates to ensure transport safety.
2. During transportation, the vehicle should be kept running smoothly to avoid severe vibration and collision.
3. Transportation vehicles shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
4. Relevant laws and regulations shall be observed during transportation to ensure legal and compliant transportation.

5. orthoxylene leakage emergency treatment measures

1. immediately cut off the leakage source, close the corresponding valve or take other measures to prevent leakage.
2. Absorb the spill with a mixture of sand, dry lime or soda ash and collect it in a closed container.
3. Avoid leakage into restricted spaces such as sewers and drains.
4. For a large number of leaks, embankments or pits should be constructed and covered with foam to reduce steam disasters.
5. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

6. of o-xylene safety protection measures

1. respiratory system protection: when the concentration in the air exceeds the standard, wear filtering gas mask (half mask). In case of emergency rescue or evacuation, it is recommended to wear air respirator or oxygen respirator.
2. Eye protection: wear chemical safety glasses.
3. Body protection: wear anti-poison penetration overalls.
4. hand protection: wear latex gloves.
5. Other protection: Smoking, eating and drinking are prohibited at the work site. After work, shower and change clothes. Maintain good hygiene habits.

7. conclusion

o-xylene as an important raw material for chemical production, its safe storage and transportation is very important. In order to ensure the safety of storage and transportation of o-xylene, it is necessary to strictly abide by the relevant storage and transportation regulations, take effective protective measures and emergency treatment measures to reduce safety risks and ensure the safety of people's lives and property.
