Safe storage and transportation specifications
for sec-butyl acetate
sec-butyl acetate, also known as sec-butyl acetate, is a colorless transparent liquid with a fruity aroma. It is widely used as a solvent and an intermediate in chemical production. However, if stored and transported improperly, sec-butyl acetate may cause safety accidents such as fire, explosion and poisoning. Therefore, understanding and adherence to the safe storage and transport specifications for sec-butyl acetate is essential.

1. the physical and chemical properties of sec-butyl acetate

the molecular formula of sec-butyl acetate is C6H12O2, the relative molecular mass is 116.17, the density is 0.872g/cm3, the melting point is -93 ℃, the boiling point is 112.1 ℃, the flash point is 21 ℃, and the spontaneous ignition point is 405 ℃. Sec-butyl acetate is slightly soluble in water, but is miscible with most organic solvents. In addition, sec-butyl acetate has flammability and toxicity, its vapor mixed with air can form an explosive mixture, fire, high heat caused by combustion explosion.

2. of sec-butyl acetate safe storage specification

1. storage place should be cool, ventilated, away from fire, heat source. The warehouse temperature should not exceed 30 ℃. It should be stored separately from oxidants and acids, and mixed storage should not be allowed. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
2. The storage container must meet the safety requirements, have sufficient strength, and have good sealing performance to prevent leakage. The container shall be inspected and maintained regularly to ensure that it is in good condition.
3. During storage, the temperature and humidity should be strictly controlled to avoid contact between sec-butyl acetate and water to prevent its decomposition and deterioration.

3. of sec-butyl acetate safety transport specification

1. before transport should first check whether the means of transport is clean, dry, there is no leakage phenomenon. Ensure that the container is well sealed during transportation to prevent leakage of sec-butyl acetate.
2. During transportation, it should be kept away from fire, high heat and other dangerous sources, and avoid direct sunlight. Transportation vehicles shall be equipped with safety facilities such as fire prevention, explosion-proof and anti-static.
3. Avoid violent vibration, collision and friction during transportation to prevent container damage and sec-butyl acetate leakage.
4. Transportation personnel shall have relevant safety knowledge, understand the nature and hazards of sec-butyl acetate, and master emergency treatment measures.

4. the toxicity protection
of sec-butyl acetate
sec-butyl acetate can irritate the eyes, skin and respiratory tract. Inhalation of high concentration of sec-butyl acetate vapor can cause poisoning symptoms, such as dizziness, headache, nausea, vomiting, etc. Therefore, during storage and transportation, the following toxicity protection measures should be taken:

1. Provide safety shower and eyewash equipment.
2. The workplace shall be ventilated.
3. The staff shall wear protective glasses, protective gloves and other personal protective equipment.
4. In the event of a leakage accident, personnel from the contaminated area shall be immediately evacuated to the safety zone, isolated, and access shall be strictly restricted. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-static overalls. Cut off the leak source as much as possible. Prevent from flowing into restricted spaces such as sewers and flood drainage ditches. Small amount of leakage: adsorption or absorption with sand or other non-combustible materials. Large leakage: build embankments or dig pits to contain. Cover with foam to reduce steam disasters. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

In short, the safe storage and transportation of sec-butyl acetate requires strict compliance with relevant specifications and safe operating procedures to ensure safety and reliability during storage and transportation. At the same time, it is necessary to strengthen the safety education and training of staff, improve safety awareness and skills, and ensure the safe use and management of sec-butyl acetate.
