Read： 567 Time：18months ago Source：Transform the World with Simplicity

1,2-Pentanediol (1,2-Pentanediol) is a common chemical raw material, widely used in plastics, coatings, inks, adhesives 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.

1. 1,2-pentanediol toxicity

1,2-pentanediol has certain toxicity to human body, inhalation, ingestion or skin contact may cause poisoning. Symptoms of poisoning include headache, dizziness, nausea, vomiting, abdominal pain, diarrhea, etc. In severe cases, symptoms such as coma and convulsions may occur. Prolonged exposure to 1,2-pentanediol may cause irritation to the eyes and skin and cause allergic reactions.

2. the flammability of 1,2-pentanediol

1,2-pentanediol is flammable and exposure to an open flame, high heat, or oxidizer may cause a fire or explosion. Therefore, it is necessary to maintain ventilation during storage and transportation, away from fire and heat sources.

3. 1,2-pentanediol safe storage specification

1. Storage place should choose a cool, ventilated, dry place, away from fire and heat sources.
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 warning signs, and smoking and open fire shall be prohibited.
4. Check and maintain the storage container regularly to ensure that it is intact.

4. 1,2-pentanediol safety transport specifications

1. transport vehicles should have the appropriate qualifications and certificates to ensure that the transport process in line with the relevant laws and regulations.
2. Keep running smoothly during transportation to avoid severe vibration and collision.
3. Transportation vehicles shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
4. During transportation, the relevant road traffic safety regulations shall be observed to ensure the safety of personnel and goods.

5. leakage emergency treatment

If 1,2-pentanediol leakage accident occurs, the following emergency treatment measures should be taken:

1. Immediately cut off the leakage source, close the valve or take other measures to prevent the leakage from continuing to leak.
2. Use sand, dry lime or soda ash mixture to absorb the leakage and avoid its diffusion into the environment.
3. Collect the leakage into a special sealed container and hand it over to a professional processing organization for disposal.
4. Ventilate the leakage area to ensure air circulation.
5. If personnel come into contact with the leakage, they should immediately take off the contaminated clothing, rinse the skin or eyes with plenty of water, and seek medical treatment in time.

In short, 1,2-pentanediol, as a common raw material for chemical production, needs to strictly abide by relevant specifications during storage and transportation to ensure its safety. By taking scientific storage and transportation measures, the hazards of 1,2-pentanediol to personnel and the environment can be effectively reduced, and the smooth progress of production activities can be guaranteed.
