Read： 882 Time：13months ago Source：Transform the World with Simplicity

Tripropylene glycol (Tripropylene Glycol, referred to as TPG) is a common chemical production raw materials, 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 of tripropylene glycol.

1. the physical and chemical properties of tripropylene glycol

tripropylene glycol is a colorless and transparent, slightly special smell of liquid, with hygroscopic. It is soluble in water, ethanol, ether and other organic solvents, but insoluble in petroleum ether. Tripropylene glycol has a high flash point and is a flammable liquid. When exposed to open flame, high heat or oxidant, it may cause combustion and explosion.

2. the toxicity of tripropylene glycol

tripropylene glycol is irritating to the eyes and skin, and inhalation of its vapors can cause respiratory irritation. Prolonged exposure may cause dry skin, chapped skin and dermatitis. Acute poisoning, can appear headache, dizziness, nausea, vomiting and other symptoms.

3. three propylene glycol storage specification

1. storage place should choose a cool, ventilated, dry place, away from the fire and heat source. Storage temperature should not exceed 30 ℃, avoid direct sunlight.
2. The storage container shall be made of corrosion-resistant materials such as stainless steel or galvanized iron drums with good sealing performance to prevent leakage.
3. The storage area shall be equipped with fire fighting equipment and leakage emergency treatment equipment, such as sand and linoleum.
4. During the storage process, the container and sealing condition should be checked regularly, and the leakage should be handled in time.

4. tripropylene glycol transport specification

1. before transport should check the packaging container is complete, sealed, to ensure that no leakage phenomenon.
2. During transportation, light loading and unloading shall be carried out to prevent impact, extrusion and dumping.
3. Transport vehicles shall be equipped with safety facilities such as fire prevention, explosion-proof and anti-static, and shall be well ventilated.
4. Hazardous factors such as high temperature, open flame and oxidant shall be avoided during transportation.
5. During transportation, it shall be stored separately from oxidants and acids, and mixed storage and transportation shall not be allowed.
6. Transport personnel should be professionally trained and familiar with the nature of tripropylene glycol and safe operation procedures.

5. leakage emergency treatment

1. small amount of leakage: with sand or other non-combustible materials adsorption or absorption, collected in a closed container, transported to the waste treatment site for disposal.
2. A large number of leaks: build a dam or dig a pit to accommodate; cover 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.

summary:

tripropylene glycol as a common chemical production raw materials, in the storage and transportation process need to strictly abide by the relevant norms to ensure safety. By understanding its physical and chemical properties, toxicity and safety protection measures, we can effectively prevent accidents and ensure the safety of personnel and the safety of the environment.
