Sodium dihydrogen phosphate (Dihydrogen Phosphate, referred to as SDP) is a common chemical raw material, widely used in food, medicine, fertilizer and other fields. Due to its dangerous nature, it is necessary to strictly observe the relevant safety regulations during storage and transportation. This article will detail the safety storage and transportation specifications for sodium dihydrogen phosphate.

1. the nature and risk
of sodium dihydrogen phosphate
Sodium dihydrogen phosphate is a colorless crystal or white powder with strong hygroscopicity, soluble in water and acidic. Its risk is mainly manifested in the following aspects:

1. Corrosion: Sodium dihydrogen phosphate has a certain degree of corrosion, which will cause certain corrosion to metal containers and equipment.

2. Irritation: Sodium dihydrogen phosphate is irritating to eyes and skin and may cause discomfort after contact.

3. Thermal stability: Sodium dihydrogen phosphate will decompose at high temperature to produce phosphoric acid and sodium hydroxide, which may cause fire or explosion.

2. the storage specifications of sodium dihydrogen phosphate

In order to ensure the safe storage of sodium dihydrogen phosphate, the following specifications need to be observed:

1. The storage place should be dry, ventilated, and cool, avoiding direct sunlight and high temperatures.

2. Storage containers should be made of corrosion resistant materials, such as plastic or glass steel drums.

3. The storage area should be kept away from dangerous substances such as fire source, heat source and oxidant.

4. During storage, the integrity and tightness of the container should be checked regularly to prevent leakage and contamination.

3. the transportation specifications of sodium dihydrogen phosphate

In order to ensure the safe transportation of sodium dihydrogen phosphate, the following specifications need to be observed:

1. Transportation vehicles should have corresponding qualifications and certificates, and transportation personnel should receive professional training.

2. During transportation, it should be kept stable and avoid violent vibration and collision.

3. The transport container shall be well sealed to prevent leakage and spilling.

4. During transportation, avoid high temperature and open fire, and keep away from dangerous substances such as oxidants.

4. of sodium dihydrogen phosphate emergency treatment measures

in the process of storage and transportation, if an accident occurs, should take the following emergency treatment measures:

1. in case of leakage, should immediately close the leakage source, with a large amount of water to wash the leakage and leakage area, and waste water collection and treatment.

2. If contact with eyes or skin, rinse immediately with water and seek medical treatment.

3. In the event of a fire, fire extinguishers such as dry powder and foam should be used to extinguish the fire, and water should be used to cool the containers and equipment.

In short, sodium dihydrogen phosphate, as a common raw material for chemical production, needs to strictly abide by relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment. At the same time, corresponding treatment measures should be taken in emergency situations to reduce losses and impacts.
