1. of safety storage and transportation specification
of p-nitrophenol Introduction

p-nitrophenol is an important raw material for chemical production, which is widely used in medicine, pesticide, dye and other fields. However, due to its toxicity and flammability, there is a greater safety risk in the storage and transportation of p-nitrophenol. Therefore, in order to ensure the safety of people's lives and property, it is very important to formulate the safe storage and transportation regulations of p-nitrophenol.

2. the physicochemical properties of p-nitrophenol

p-nitrophenol is a yellow crystalline solid with a special odor. It has a high melting point of 114-116 ° C, a boiling point of 279 ° C, and a density of 1.47g/cm3. p-nitrophenol is insoluble in water, but soluble in ethanol, ether and other organic solvents. In addition, p-nitrophenol is toxic and corrosive and can cause skin irritation and eye damage.

3. safety storage specifications for p-nitrophenol

1. Storage facility requirements: p-nitrophenol should be stored in a cool, dry, well-ventilated special warehouse, avoiding direct sunlight and high temperature. The floor of the warehouse shall be paved with anti-leakage materials and set up a drainage system.
2. Storage container requirements: p-nitrophenol should be stored in a container with good sealing performance, and the container material should have corrosion resistance. The container shall be inspected regularly during storage to ensure that there are no leaks.
3. Storage safety measures: fire-fighting equipment and safety warning signs shall be set up in the warehouse, and safety inspection shall be carried out regularly. Dangerous behaviors such as smoking and open fire are prohibited in the warehouse.
4. Personnel management requirements: warehouse management personnel should be professionally trained to understand the physical and chemical properties of p-nitrophenol and safe operation procedures. Wear protective gloves, masks and other personal protective equipment during storage.

4. safety transportation specifications for p-nitrophenol

1. Transportation vehicle requirements: p-nitrophenol should be transported by special transportation vehicles, and the vehicles should have good sealing performance and anti-collision measures. During transportation, the vehicle speed should be kept stable to avoid sudden braking and severe vibration.
2. Transport packaging requirements: p-nitrophenol should be packaged with packaging materials that meet the requirements, and the packaging should be tight and firm to prevent damage and leakage during transportation. The name, hazard level and manufacturer of p-nitrophenol shall be clearly marked on the package.
3. Transportation safety measures: During transportation, the road traffic safety regulations should be observed, the distance between vehicles should be maintained, and overloading and speeding should be avoided. Transportation vehicles shall be equipped with fire fighting equipment and leakage emergency treatment equipment to deal with emergencies.
4. Personnel management requirements: transportation personnel should be professionally trained to understand the physical and chemical properties of p-nitrophenol and safe operation procedures. Personal protective equipment such as protective gloves and masks shall be worn during transportation.

5. emergency treatment measures

1. skin contact: if the skin comes into contact with p-nitrophenol, immediately remove the contaminated clothing, rinse with a large amount of flowing water for at least 15 minutes, and seek medical treatment in time.
2. Eye contact: If the eye comes into contact with p-nitrophenol, immediately lift the eyelid, rinse thoroughly with a large amount of flowing water or normal saline for at least 15 minutes, and seek medical attention in time.
3. Inhalation: If inhaling p-nitrophenol vapor, it should be quickly separated from the scene to the fresh air, keep the respiratory tract unobstructed, and seek medical treatment in time.
4. Ingestion: If you eat p-nitrophenol by mistake, you should drink plenty of warm water immediately and seek medical treatment in time after vomiting.

6. summary

As an important raw material for chemical production, the safety and reliability of p-nitrophenol are of great significance to the safety of people's lives and property. Therefore, in the process of storage and transportation, we should strictly abide by the relevant norms and safety operation procedures, strengthen safety management and personnel training, and ensure the safety and reliability of p-nitrophenol.
