Trisodium phosphate in the field of chemical production of raw materials in the safety of storage and transportation specifications

1. Introduction

Trisodium phosphate is an important inorganic salt chemical raw materials, widely used in food, medicine, printing and dyeing, metallurgy and other industries. Due to its special physical and chemical properties, trisodium phosphate needs to strictly comply with certain specifications during storage and transportation to ensure its safety. This article will elaborate on the safety storage and transportation specifications of trisodium phosphate.

2. the physical and chemical properties of trisodium phosphate

trisodium phosphate, the chemical formula is Na3PO4, which is a white crystalline powder with strong hygroscopicity. It is readily soluble in water and its aqueous solution is alkaline. Trisodium phosphate will gradually absorb moisture and carbon dioxide in the air and convert it into disodium hydrogen phosphate.

3. trisodium phosphate safety storage specifications

1. Storage environment: trisodium phosphate should be stored in a dry, cool, well-ventilated indoor environment, avoid direct sunlight and high temperature.
2. Storage container: Plastic or glass containers should be used to store trisodium phosphate, and metal containers should be avoided to prevent corrosion.
3. Storage period: The storage period of trisodium phosphate is generally 2 years. After expiration, the quality should be re-inspected before deciding whether to use it.

4. trisodium phosphate safety transport specification

1. transport packaging: trisodium phosphate should be lined with plastic bags woven bag or carton packaging, to ensure that the packaging is tight, not leaking.
2. Transport vehicles: Transport vehicles with rain-proof, sun-proof and moisture-proof functions should be used to ensure that trisodium phosphate is not affected by the environment during transportation.
3. transport personnel: transport personnel should be professionally trained to understand the nature of sodium phosphate and transport safety knowledge.

5. trisodium phosphate safety operation specification

1. Operators should be professionally trained to understand the nature of trisodium phosphate and safe operation knowledge.
2. Wear protective gloves, goggles and other personal protective equipment during operation to avoid direct contact with trisodium phosphate.
3. The operation site should be equipped with ventilation facilities to maintain air circulation and avoid high dust concentration of trisodium phosphate.

6. trisodium phosphate leakage treatment specification

1. in case of trisodium phosphate leakage, stop the operation immediately and close the leakage source to prevent the leakage from spreading.
2. Use a dry, clean shovel or absorbent material to collect the leakage and place it in a sealed container.
3. Ventilate the leakage area to ensure air circulation and avoid excessive dust concentration.
4. If personnel come into contact with the leakage, immediately use plenty of water to rinse, and medical inspection.

7. conclusion

trisodium phosphate as an important chemical raw material, its safe storage and transportation is very important. By strictly complying with the physical and chemical properties, safety storage specifications, safety transportation specifications, safety operation specifications and leakage handling specifications of trisodium phosphate, the safety of trisodium phosphate during production, transportation and use can be effectively guaranteed, and potential risks can be reduced.
