[Chemical Knowledge]：Specification for storage and transportation of dilute phosphoric acid

Dilute phosphoric acid has important application value in the field of chemical production raw materials, but its safety and storage and transportation regulations are very important to ensure production safety and personnel health. This article will detail the safety storage and transportation specifications of dilute phosphoric acid, aiming to provide useful reference and guidance for enterprises and individuals.

1. the basic properties of dilute phosphoric acid

dilute phosphoric acid is a colorless, transparent, corrosive liquid with strong acidity. It is easily miscible with water, ethanol and other solvents, and easy to deliquesce in the air. Dilute phosphoric acid is harmful to the human body. After contact, it will cause irritation and burns of the skin, eyes and other parts. Inhalation of steam will cause respiratory tract irritation and pulmonary edema.

2. safety storage specifications for dilute phosphoric acid

1. Storage location selection: dilute phosphoric acid should be stored in a cool, dry, well-ventilated special warehouse, away from fire, heat and direct sunlight. The warehouse floor shall be anti-skid and anti-seepage, and equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment.
2. Storage container requirements: dilute phosphoric acid should be stored in corrosion resistant containers, such as polyethylene, polypropylene and other materials of storage tanks or bottles. Containers shall be well sealed to prevent leakage and volatilization.
3. Storage limit control: According to the enterprise scale and production process, the storage amount of dilute phosphoric acid should be reasonably controlled to avoid the potential safety hazard caused by excessive storage.
4. Personnel management requirements: The storage site shall be managed by a special person, who shall be responsible for regularly checking the integrity and tightness of the storage container, as well as the operation of the ventilation, fire protection and other facilities of the warehouse.

3. dilute phosphoric acid transport specification

1. transport vehicle selection: should choose a corrosion resistance of special transport vehicles, to ensure that the vehicle is in good condition, with effective fire, explosion, leakage and other safety facilities.
2. Requirements for transportation containers: Dilute phosphoric acid should be transported in special corrosion-resistant containers, and the containers should be well sealed, clearly marked, and comply with relevant regulations and standards.
3. Transportation safety measures: during transportation, measures should be taken to prevent leakage, splash and other measures, such as the use of splash cover, shockproof pad. At the same time, should avoid high temperature, fire and other dangerous factors to ensure transportation safety.
4. Transport personnel management: Transport personnel should be professionally trained to understand the nature of dilute phosphoric acid and safe operation procedures, with the ability to respond to emergencies.

4. safety operation of dilute phosphoric acid

1. Preparation before operation: before operation should wear protective equipment, such as protective gloves, goggles, etc., to ensure the health of the operator.
2. Operation process control: The operation process should be kept stable to avoid splashing and leakage. At the same time, parameters such as operating temperature and pressure should be strictly controlled to ensure that they are within a safe range.
3. Cleaning after operation: After the operation is completed, the site should be cleaned in time, and the discarded dilute phosphoric acid and containers should be properly disposed in accordance with relevant regulations.

5. emergency treatment measures

1. skin contact: immediately take off the contaminated clothing, rinse with plenty of flowing water for at least 15 minutes, and then seek medical treatment.
2. Eye contact: immediately lift the eyelid, rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes, and then seek medical attention.
3. Inhalation: should be quickly out of the scene to the fresh air, keep the respiratory tract unobstructed. If breathing is difficult, oxygen should be given and then medical attention should be sought.
4. Ingestion: Drink plenty of warm water immediately and seek medical attention after vomiting.

In short, dilute phosphoric acid is widely used in the field of chemical production raw materials, but its safety and storage and transportation regulations are very important to ensure production safety and personnel health. Therefore, enterprises and individuals should strictly abide by relevant regulations and standards when operating dilute phosphoric acid to ensure the safety of storage, transportation and operation.
