The safety storage and transportation specification
of diethylene glycol
1. Introduction

diethylene glycol (Diethylene Glycol, referred to as DEG) is a common chemical production raw material, widely used in plastics, fibers, coatings, antifreeze and other fields. However, diethylene glycol can be hazardous to human health and the environment if stored and transported improperly. Therefore, it is important to understand the safe storage and transportation specifications of diethylene glycol.

2. the properties and hazards of diethylene glycol

diethylene glycol is a colorless, odorless, transparent liquid, hygroscopic and toxic. Prolonged exposure or inhalation of diethylene glycol vapor may cause eye and respiratory irritation, headache, dizziness, nausea and other symptoms, and may cause damage to the liver and kidneys in severe cases. In addition, diethylene glycol is also flammable and may cause combustion in case of open flame, high heat or oxidant contact.

3. diethylene glycol safety storage specification

1. The storage place should choose a cool, ventilated and dry place, away from open flames, heat sources and oxidants.
2. The storage container shall be well sealed to prevent leakage and volatilization.
3. The storage area shall be provided with fire fighting equipment and leakage emergency treatment equipment.
4. Check and maintain the storage container regularly to ensure that it is intact.

4. diethylene glycol safety transportation specifications

1. Before transportation, check whether the packaging is intact to ensure that there is no leakage.
2. In the process of transportation, light loading and unloading should be carried out to avoid collision, extrusion and dumping.
3. Transportation vehicles shall be provided with safety measures such as fire prevention, explosion-proof and anti-static.
4. During transportation, avoid high temperature and open fire, and keep away from dangerous substances such as oxidants.

5. leakage emergency treatment

1. In case of leakage, the fire source should be cut off immediately, and measures should be taken to prevent the leakage from entering the sewer, drainage ditch and other restricted spaces.
2. When a small amount of leakage, sand or other non-combustible materials can be used for adsorption or absorption, or a large amount of water can be washed and diluted and discharged into the waste water system.
3. In case of a large amount of leakage, embankments or pits shall be constructed 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.

6. protective measures

1. Respiratory system protection: when the concentration in the air exceeds the standard, wear a self-priming filter gas mask (half mask). In case of emergency rescue or evacuation, it is recommended to wear air respirator.
2. Eye protection: wear chemical safety glasses.
3. Body protection: wear anti-poison penetration overalls.
4. Hand protection: wear rubber 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. first aid measures

1. Skin contact: remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
2. Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.
3. Inhalation: Quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
4. ingestion: gargle with water and drink milk or egg white. Seek medical attention.

8. conclusion

diethylene glycol as a common chemical production raw material, its safety storage and transportation is very important. By understanding the nature and hazards of diethylene glycol, strictly observing storage and transportation regulations, and taking effective protective measures and first aid measures, the risks to human health and the environment can be minimized.
