Read： 415 Time：12months ago Source：Transform the World with Simplicity

Isophthalic acid (IPA) is a common chemical raw material, widely used in plastics, fiber, medicine and other fields. Due to its corrosive and toxic properties, strict compliance with regulations is required during storage and transportation to ensure safety. This article will detail the safety storage and transportation specifications of isophthalic acid.

1. the properties and hazards of isophthalic acid

isophthalic acid is a white crystalline powder, with strong corrosion and toxicity. It has a stimulating effect on the skin and eyes, inhalation or ingestion will cause harm to the human body. At the same time, isophthalic acid is also flammable, and it will cause combustion or explosion when exposed to open flame or high heat.

2. isophthalic acid storage specification

1. The storage place should be dry, ventilated, cool, and avoid direct sunlight and high temperature.
2. The storage container should be made of corrosion-resistant materials, such as stainless steel or plastic materials.
3. The storage area should be away from fire and heat sources, and smoking and open flames are prohibited.
4. The storage area shall be equipped with leakage emergency treatment equipment and personal protective equipment.

3. isophthalic acid transport specification

1. transport vehicles should meet the transport requirements of dangerous goods, with appropriate protective measures and fire fighting equipment.
2. During transportation, it should be kept stable to avoid violent vibration and collision.
3. Transport personnel shall be trained in the transport of dangerous goods and have the appropriate knowledge and skills.
4. During transportation, traffic rules should be observed to keep the speed stable and avoid overspeed and sudden braking.

4. isophthalic acid leakage treatment specification

1. found leakage should immediately stop the operation, evacuate personnel to a safe area.
2. Cut off the leakage source and absorb the leakage with sand or other non-combustible materials.
3. Large spills shall be contained by embankments or pits and pumped into tankers or special collectors.
4. Wear protective gloves and glasses when handling the leakage to avoid direct contact.

5. isophthalic acid first aid measures

1. skin contact: immediately remove contaminated clothing, with a large amount of flowing water rinse for at least 15 minutes. Seek medical attention.
2. Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.
3. Inhalation: Quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
4. ingestion: gargle with water and drink milk or egg white. Seek medical attention.

6. isophthalic acid fire protection measures

1. dangerous characteristics: in case of fire, high heat flammable. Powder and air can form an explosive mixture, when it reaches a certain concentration, it will explode when it meets Mars. It is decomposed by high heat to release toxic gases.
2. Harmful combustion products: carbon monoxide, carbon dioxide.
3. Fire extinguishing method: firefighters must wear gas masks and full-body fire fighting clothing to put out the fire in the upper wind direction. Extinguishing agent: atomized water, foam, dry powder, carbon dioxide, sand.

To sum up, isophthalic acid needs to strictly comply with regulations during storage and transportation to ensure safety. At the same time, in the case of leakage and first aid, corresponding measures should be taken to avoid harm to human body and environment.
