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

1. Introduction

phosphoric acid is an important chemical raw material, widely used in chemical fertilizers, food additives, detergents and other fields. However, phosphoric acid is corrosive and harmful to human body and environment. Therefore, during the storage and transportation of phosphoric acid, relevant safety regulations must be strictly observed to ensure the safe use of phosphoric acid.

2. the properties and hazards of phosphoric acid

phosphoric acid is an inorganic acid, with strong corrosive and irritating. Exposure to phosphoric acid can cause irritation and damage to the skin, eyes and respiratory tract. Chronic exposure may also lead to chronic toxicity. In addition, phosphoric acid is also harmful to the environment, which may lead to water and soil pollution.
Storage specifications for
3. phosphoric acid

1. Storage facilities: phosphoric acid should be stored in a cool, dry, well-ventilated special warehouse, away from fire and heat sources. The warehouse floor shall be anti-skid and equipped with leakage emergency treatment equipment.
2. Storage container: phosphoric acid should be stored in a special container, which should have corrosion resistance and tightness to prevent phosphoric acid leakage. The container shall be inspected and maintained regularly to ensure that it is in good condition.
3. Storage identification: Obvious warning identification shall be set in the phosphoric acid storage area, including "corrosive", "toxic" and other identification to remind personnel to pay attention to safety.
Transportation specifications for
4. phosphoric acid

1. Transportation vehicles: Phosphoric acid should be transported by special transportation vehicles. The vehicles should have corrosion resistance and sealing properties to prevent phosphoric acid leakage. The condition of the vehicle should be checked before transportation to ensure safety and reliability.
2. Transportation personnel: transportation personnel should be professionally trained to understand the nature and hazards of phosphoric acid and master emergency treatment measures. During transportation, we should be vigilant and deal with abnormal situations in time.
3. Transportation route: phosphoric acid transportation should choose a safe transportation route to avoid passing through densely populated areas and sensitive environmental areas. During transportation, the vehicle speed shall be kept stable, and operations such as sudden braking and sharp turning shall be avoided.
emergency treatment
for
5. phosphoric acid leakage
1. personnel protection: in case of phosphoric acid leakage, people nearby should be evacuated immediately to avoid contact with phosphoric acid. Handling personnel should wear professional protective equipment, such as protective gloves, goggles, etc.
2. Leakage treatment: in case of a small amount of leakage, sand, dry lime or soda ash can be mixed and recovered; in case of a large amount of leakage, a dam or pit shall be constructed and transferred to a tank car or a special collector by pump.

6. conclusion

phosphoric acid as an important chemical raw material, in the process of production and use must strictly abide by the relevant safety regulations to ensure the safe storage and transportation of phosphoric acid. By strengthening management and training, improving the safety awareness and operation skills of personnel, the occurrence of phosphoric acid leakage accidents can be effectively reduced, and the safety of people's lives and property can be guaranteed.
