Read： 791 Time：12months ago Source：Transform the World with Simplicity

Terephthalic acid (PTA) is a common chemical raw material, which is widely used in the production of plastics, fibers, resins and other fields. Due to its corrosive and flammable nature, it is necessary to strictly comply with relevant safety regulations during storage and transportation.

1. hazardous
of terephthalic acid
terephthalic acid is a white crystalline powder with strong corrosiveness and flammability. If it comes into contact with the skin, it will cause skin irritation and allergy; if it is inhaled, it will cause irritation and harm to the respiratory system. In addition, terephthalic acid is also toxic, if long-term contact or inhalation, will cause chronic poisoning to the human body.

2. terephthalic acid storage specification

1. The storage place should be dry, ventilated, cool, avoid direct sunlight and high temperature.
2. The storage container should have anti-corrosion performance, good sealing performance, prevent leakage and volatilization.
3. The storage area should be kept away from dangerous substances such as fire sources, heat sources and oxidants, and avoid contact with alkaline substances.
4. During storage, the storage container should be inspected and maintained regularly to ensure that it is intact.

3. terephthalic acid transport specifications

1. transport vehicles should have anti-corrosion, explosion-proof, fire and other properties to ensure the safety of the transport process.
2. During transportation, it should be stable, avoid violent vibration and collision, and prevent package damage and leakage.
3. During transportation, it should be kept away from dangerous substances such as fire source, heat source and oxidant, and avoid contact with alkaline substances.
4. In the process of transportation, the transportation vehicle should be inspected and maintained regularly to ensure its normal operation and safety performance.

4. of terephthalic acid emergency treatment measures

1. If a leakage accident occurs, should immediately cut off the leakage source, with sand, dry lime and other adsorption materials to absorb the leakage, and put it in a closed container.
2. In the event of a fire accident, fire extinguishing equipment should be used immediately to extinguish the fire, and the container should be cooled with water to prevent explosion.
3. In the event of a personnel poisoning accident, the poisoned person should be immediately moved to a ventilated place, given oxygen to breathe, and promptly sent to a doctor for treatment.

In short, terephthalic acid 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. Therefore, in the process of production, storage and transportation, the relevant safety regulations should be strictly observed to ensure the safety and reliability of terephthalic acid.
