Read： 542 Time：13months ago Source：Transform the World with Simplicity

Dipropylene glycol (DPG) is a common chemical raw material, widely used in coatings, inks, cleaning agents, plastics, pharmaceuticals and other fields. Due to its flammable and toxic properties, it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article will detail the safety storage and transportation specifications for dipropylene glycol.

1. the physical and chemical properties of dipropylene glycol

dipropylene glycol is a colorless, transparent, pungent odor liquid, with a high boiling point, flash point and ignition point, but flammable, in case of open flame, high heat can cause combustion. In addition, dipropylene glycol is also toxic. Prolonged exposure or inhalation of its vapor can cause headache, dizziness, nausea and other symptoms. In severe cases, it can lead to coma and death.

2. dipropylene glycol storage specification

1. The storage place should choose a dry, ventilated and cool place, away from open flame, heat source and oxidant.
2. The storage container should use stainless steel or plastic container with good sealing performance, and avoid using iron container to avoid chemical reaction.
3. During storage, the sealing performance of the container should be checked regularly to prevent leakage.
4. The storage area shall be provided with obvious safety signs and warning signs, and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.

3. dipropylene glycol transportation specifications

1. Before transportation, the transportation vehicles should be fully inspected to ensure that the vehicles are in good working condition.
2. Keep running smoothly during transportation to avoid severe vibration and collision.
3. Transport vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.
4. During transportation, avoid driving in high temperature periods to avoid combustion accidents caused by temperature rise.

4. dipropylene glycol leakage emergency treatment

1. If a leakage accident occurs, the leakage source should be cut off immediately, mixed with sand, dry lime or soda ash and recycled to the waste treatment site.
2. In case of a large amount of leakage, embankment or pit shall be constructed and covered with foam to reduce steam disaster. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.
protective measures of
5. dipropylene glycol

1. respiratory system protection: when the concentration in the air exceeds the standard, wearing a filtering gas mask (half mask).
2. Eye protection: wear chemical safety glasses.
3. Body protection: wear anti-static 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. Pre-employment and regular medical examinations are carried out.

In short, dipropylene glycol is a common raw material for chemical production, and its safety and storage and transportation regulations are of great significance to ensure production safety and personnel health. In actual operation, the relevant specifications should be strictly observed to ensure the storage and transportation safety of dipropylene glycol.
