Stearic acid safety storage and transportation specification

1. Introduction

stearic acid as a common chemical production materials, widely used in plastics, rubber, cosmetics, food and other fields. However, due to its special physical and chemical properties, stearic acid has certain safety risks during storage and transportation. In order to ensure the safe use of stearic acid, this article aims to discuss its safe storage and transportation specifications.

2. physical and chemical properties of stearic acid

stearic acid is a saturated fatty acid, molecular formula is C18H36O2, molecular weight is 284.48. It usually exists in the form of white or yellowish waxy solid, with good thermal stability, insoluble in water, but soluble in hot ethanol, ether and other organic solvents.

3. Stearic acid safety storage specification

1. Storage place selection: Stearic acid should be stored in a dry, cool, well-ventilated indoor place, avoid direct sunlight and high temperature environment.
2. Storage container requirements: Use a well-sealed container for storage to prevent the oxidation of stearic acid in contact with air.
3. Storage limit: according to the production needs and site conditions, reasonable control of storage, to avoid excessive storage security risks.
4. Identification and warning: obvious identification and warning shall be set up in the storage place, indicating the name, danger and other information of stearic acid.
Safety transportation specifications for
4. stearic acid

1. Selection of transportation vehicles: Use special vehicles that meet the regulations for transportation to ensure that the vehicles have good sealing and shockproof performance.
2. Requirements for transportation personnel: transportation personnel should be professionally trained to understand the physical and chemical properties of stearic acid and transportation safety knowledge.
3. Transport packaging requirements: packaging materials in accordance with the provisions of the packaging, to ensure that stearic acid in the transport process will not leak or damage.
4. Transportation route planning: Choose a reasonable transportation route to avoid passing through high temperature, humidity and other environments that are not conducive to the stability of stearic acid.

5. Stearic Acid Leakage Emergency Treatment

During the storage and transportation of stearic acid, in case of leakage, the following emergency treatment measures should be taken:

1. Immediately cut off the leakage source, close the corresponding valve or take other measures to prevent leakage.
2. Use special absorbent materials to absorb the leakage and avoid its diffusion into the environment.
3. Transport the collected leakage to the designated hazardous waste treatment site for treatment to avoid environmental pollution.
4. Ventilate the leakage area to ensure air circulation and avoid harmful gas accumulation.
5. If a person comes into contact with the leak, rinse immediately with plenty of water and seek medical attention.

6. conclusion

stearic acid as a common chemical production raw material, in the process of storage and transportation should strictly abide by the corresponding safety standards. The safety risk of stearic acid during storage and transportation can be reduced by selecting suitable storage and transportation places, using containers and packaging materials that meet the requirements, and planning reasonable transportation routes. At the same time, strengthen the training of leakage emergency response capabilities to ensure that effective measures can be taken quickly in the event of a leakage accident to ensure the safety of personnel and the environment.
