Read： 460 Time：12months ago Source：Transform the World with Simplicity

Para-hydroxybenzoic acid (also known as salicylic acid) is a common organic compound in the field of chemical production raw materials, which is widely used in pharmaceutical, cosmetics, food preservation and other industries. Due to its certain toxicity and corrosiveness, it is necessary to strictly comply with relevant safety regulations during storage and transportation.

1. the safety
of p-hydroxybenzoic acid
p-hydroxybenzoic acid has certain toxicity to human body. Prolonged exposure or inhalation of its dust may cause irritation and damage to respiratory system, skin and eyes. Ingestion of large amounts of p-hydroxybenzoic acid may lead to poisoning. Symptoms include nausea, vomiting, headache, and dizziness. Therefore, when handling p-hydroxybenzoic acid, personal protective equipment such as protective clothing, gloves, goggles must be worn, and the work area must be well ventilated.

2. storage specifications for p-hydroxybenzoic acid

1. Storage environment: p-hydroxybenzoic acid should be stored in a dry, cool, well-ventilated place, avoid direct sunlight and high temperature.
2. Storage container: A container with corrosion resistance should be used to store p-hydroxybenzoic acid, and ensure that the container has good airtightness to prevent leakage.
3. Storage identification: obvious warning identification shall be set up in the storage area to indicate the name, danger, emergency measures and other information of p-hydroxybenzoic acid.

3. the transportation specifications for p-hydroxybenzoic acid

1. Transportation containers: Special corrosion-resistant transportation containers should be used to ensure that the containers will not break or leak during transportation.
2. Transport identification: obvious dangerous goods identification shall be set on the transport vehicle or container, indicating the name, danger and other information of p-hydroxybenzoic acid.
3. Transportation conditions: During transportation, you should maintain a stable driving, avoid violent vibration and collision, and pay attention to sun protection, rain protection and other measures.

4. emergency measures

during storage and transportation, in case of leakage, fire and other accidents, the following emergency measures should be taken:

1. Leakage treatment: in case of leakage, the leakage source should be cut off immediately, and the leakage should be covered and cleaned with sand, dry lime and other adsorption materials to avoid flowing into sewers or drainage ditches.
2. Fire treatment: In case of fire, fire extinguishing equipment such as dry powder and foam shall be used immediately to extinguish the fire, and water shall be used to cool the surrounding equipment to prevent the fire from expanding. At the same time should pay attention to protect the safety of personnel on site, timely evacuation.

In short, p-hydroxybenzoic acid is a common raw material for chemical production, and its safety and storage and transportation regulations are of great significance to ensure production safety and personnel health. During the operation, you should strictly abide by the relevant safety regulations, wear protective equipment, ensure that the work area is well ventilated, and avoid prolonged contact or inhalation of dust. In case of any accident, emergency measures shall be taken in time to ensure personnel safety and environmental safety.
