[Chemical Knowledge]：Specification for storage and transport of salicylic acid

Salicylic acid in the field of chemical production of raw materials in the safety of storage and transport specifications

1. Introduction

Salicylic acid is a widely used in chemical, pharmaceutical, food and other industries important raw materials. Due to its irritating and corrosive nature, special attention needs to be paid to safety during storage and transportation. In order to ensure the safety of salicylic acid in production, use and circulation, it is very important to formulate a set of strict storage and transportation regulations.

2. the physical and chemical properties of salicylic acid

Salicylic acid is an organic compound with the chemical formula C7H6O3, which has a colorless crystal or a white powder. It has a pungent odor, and can be dissolved in water, ethanol, ether and other organic solvents. Salicylic acid is corrosive and has a certain corrosive effect on metals.

3. the harmfulness of salicylic acid

salicylic acid is irritating to human skin and eyes. Prolonged exposure or inhalation of salicylic acid dust may cause adverse reactions in the respiratory tract, skin and digestive system. Ingestion of large amounts of salicylic acid may lead to poisoning, with symptoms including nausea, vomiting, headache, and dizziness.

4. storage specification

1. storage environment: salicylic acid should be stored in a dry, cool, well-ventilated indoor environment, avoid direct sunlight. The storage temperature should be controlled below 25 ℃, and the relative humidity should not exceed 75%.
2. Storage container: Use a special sealed container to store salicylic acid to ensure that the container has good sealing performance and prevent salicylic acid from leaking. The container should be marked with the name and hazardous nature of salicylic acid.
3. Storage location: Salicylic acid should be stored at a certain distance from the ground and the wall to avoid contact with water and fire. The storage area shall be provided with obvious safety warning signs.

5. transport specification

1. transport vehicles: the use of dangerous goods transport qualified vehicles for salicylic acid transport, to ensure that the vehicle in good condition, in line with the relevant safety standards.
2. Packaging requirements: Salicylic acid should be packaged with packaging materials that meet the requirements, and the packaging should be tight and firm to prevent leakage during transportation. The packaging should be clearly marked with the name of salicylic acid, dangerous nature, manufacturer and contact information and other information.
3. transport personnel: transport salicylic acid personnel should have the relevant knowledge of dangerous goods transport, professional training and obtain the corresponding qualification certificate.
4. Transport routes: Choose reasonable transport routes and try to avoid passing through densely populated areas and sensitive areas. During transportation, the traffic rules shall be observed, the speed shall be kept stable, and operations such as sudden braking and sharp turning shall be prevented.
5. Emergency measures: in the process of transportation, once the leakage of salicylic acid and other accidents occur, emergency measures should be taken immediately, such as the use of sand, dry lime and other absorption of leakage, to avoid diffusion, and timely report to the relevant departments.

6. safe operation specification

1. Operators should be professionally trained to understand the nature of salicylic acid and safe operation procedures.
2. Wear protective clothing, gloves, goggles and other personal protective equipment during operation to avoid direct contact with salicylic acid.
3. The operation area should be equipped with ventilation facilities to maintain air circulation and reduce the concentration of salicylic acid dust.
4. Regularly conduct safety inspections in the operating area to ensure that equipment, containers, etc. are in good condition.

7. Waste Disposal Specification

1. Waste salicylic acid should be properly disposed in accordance with relevant regulations and standards to avoid environmental pollution.
2. Wastes shall be stored in special containers, which shall be sealed and clearly marked.
3. The treatment of waste shall meet the requirements of environmental protection, and incineration, chemical treatment and other methods can be adopted for harmless treatment.

In short, in order to ensure the safe storage and transportation of salicylic acid in the field of chemical production raw materials, it is necessary to strictly abide by relevant regulations and standards, strengthen the training of management and operators, and ensure the effective implementation of various safety measures. By following the standard storage, transportation and safe operation procedures, the harm of salicylic acid to the environment and human body can be reduced, and the safety of production activities can be guaranteed.
