Read： 929 Time：14months ago Source：Transform the World with Simplicity

Triethylene Glycol (TEG) is a common chemical raw material, which is widely used in solvents, plasticizers, antifreeze and other fields. Due to its toxicity and flammability, 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 triethylene glycol.

1. the properties of triethylene glycol

triethylene glycol is a colorless, transparent, slightly sweet liquid, with strong moisture absorption and corrosion. Its chemical properties are stable, not easy to oxidation, decomposition and other reactions, but at high temperature, acidic or alkaline conditions, prone to hydrolysis reaction.

2. triethylene glycol diethylene glycol toxicity

triethylene glycol has certain toxicity to human body, mainly through inhalation, ingestion and skin contact and other ways into the human body. Long-term exposure or inhalation of high-concentration triethylene glycol vapor may cause poisoning, causing headache, dizziness, nausea, vomiting and other symptoms, and may damage the liver and kidneys in severe cases.

3. diethylene glycol storage specification

1. The storage place should choose a dry, cool, well-ventilated place, avoid direct sunlight and high temperature.
2. The storage container shall be a special container with good sealing performance to avoid leakage and volatilization.
3. The storage area shall be provided with obvious safety signs and warning signs, and open fire and smoking are prohibited.
4. Check and maintain the storage container regularly to ensure that it is intact.

4. diethylene glycol transport specifications

1. Before transport, the safety performance of transport vehicles and the sealing performance of transport containers should be checked to ensure that they meet the relevant requirements.
2. During transportation, it is necessary to keep running smoothly, avoid violent vibration and collision, and prevent container damage and leakage.
3. Transport vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment to deal with emergencies.
4. During transportation, relevant laws, regulations and regulations shall be observed to ensure safe transportation.

5. leakage emergency treatment

in case of accidental diethylene glycol leakage accident, the following measures should be taken for emergency treatment:

1. immediately cut off the leakage source, close the valve or take other measures to prevent the leakage from continuing to leak.
2. Cover the leakage with non-combustible materials such as sand, dry lime or soda ash to reduce its volatilization and diffusion.
3. Avoid leakage into sewers, drains and other restricted spaces to prevent environmental pollution.
4. If the leakage is large, report to the local environmental protection department in time and deal with it in accordance with relevant regulations.

In short, as a common raw material for chemical production, triethylene glycol needs to strictly abide by relevant specifications during storage and transportation to ensure safety. By understanding its nature, toxicity and storage and transportation specifications, we can effectively prevent and reduce the occurrence of accidents and ensure the safety of people's lives and property.
