Polyphosphoric acid in the field of chemical production of raw materials in the safety of storage and transportation specifications

1. Introduction

polyphosphoric acid is an important chemical raw material, widely used in fertilizer, metallurgy, medicine, food and other fields. However, due to its strong corrosiveness and toxicity, the storage and transportation of polyphosphoric acid must strictly comply with relevant safety regulations to ensure the safety of personnel and the environment. This article will detail the safety storage and transportation specifications of polyphosphoric acid in the field of chemical production raw materials.

2. the nature and harm of polyphosphoric acid

polyphosphoric acid is a colorless transparent or slightly yellow viscous liquid, with strong corrosive and oxidizing. It has a strong corrosive effect on metal, rubber, skin, etc., and can cause severe burns and poisoning. Therefore, during the storage and transportation of polyphosphoric acid, special attention must be paid to its safety and environmental protection.

3. polyphosphoric acid storage specifications

1. Storage facilities: polyphosphoric acid should be stored in a cool, dry, well-ventilated special warehouse, away from fire, heat and direct sunlight. The floor of the warehouse shall be treated with anti-corrosion and a leakage collection system shall be set up.
2. Storage container: Polyphosphoric acid should be stored in a special container made of corrosion-resistant materials such as polyethylene and polypropylene. The container should be well sealed to prevent leakage.
3. Storage identification: Obvious warning identification shall be set up in the storage area of polyphosphoric acid, including identification of "corrosive substances" and "toxic substances", and corresponding emergency treatment equipment shall be equipped.

4. polyphosphoric acid transport specification

1. transport vehicles: polyphosphoric acid should be used for special chemical transport vehicles for transport, the vehicle should have good sealing performance and anti-corrosion treatment, to ensure that in the transport process will not occur leakage accident.
2. Transport packaging: The transport packaging of polyphosphoric acid should meet relevant standards, and the packaging should be firm and sealed to prevent damage or leakage during transportation. Each packaging unit shall be clearly marked with information such as the name of the substance, danger and emergency measures.
3. Transportation route: The transportation of polyphosphoric acid should choose a reasonable transportation route to avoid passing through sensitive areas such as densely populated areas and water source protection areas. During transportation, you should abide by traffic rules, keep the speed stable, and avoid sudden braking to reduce transportation risks.

5. polyphosphoric acid safety operation specification

1. operators must undergo professional training, understand the nature of polyphosphoric acid and safe operation procedures, wear professional protective equipment, such as protective gloves, protective glasses, etc.
2. During the operation, the operation site should be kept clean and ventilated to avoid polyphosphoric acid contact with skin and eyes.
3. In case of polyphosphoric acid leakage accident, the emergency plan shall be started immediately and effective measures shall be taken to prevent the accident from expanding.

6. conclusion

polyphosphoric acid as an important chemical raw material, its safety and environmental protection must be strictly guaranteed in the process of storage and transportation. By complying with the relevant storage and transportation specifications, the harm of polyphosphoric acid to personnel and the environment can be effectively reduced, and the safety and stability of production can be guaranteed. Therefore, in actual operation, relevant regulations must be strictly observed to ensure the safe storage and transportation of polyphosphoric acid.
