China hazardous chemicals directory for acetone storage requirements

Acetone (Acetone) is a common organic compound, widely used in chemical, pharmaceutical, cosmetics, electronics and other industries. Due to its flammable and volatile nature, acetone needs to be stored and handled in strict compliance with relevant regulations and safety standards. According to the China List of Hazardous Chemicals, acetone is classified as a hazardous chemical and therefore must meet specific requirements when stored. This article will analyze the storage requirements of acetone in detail and discuss how to ensure its safety during storage.

Acetone Basic Properties and Hazards

Acetone is a colorless, flammable liquid with a special keto taste. It is miscible with water in any proportion and with most organic solvents. The chemical properties of acetone are relatively stable, but it is easy to burn under high temperature or open flame conditions, and it is a flammable liquid.

According to the list of hazardous chemicals in China, acetone is classified as a hazardous chemical, and its risk is mainly reflected in the following aspects:

1. Flammability: Acetone has a low flash point (about -19°C) and is easily ignited in air.
2. Volatile: acetone at room temperature volatile faster, easy to form flammable gas.
3. Oxidative: acetone at high temperature or oxygen sufficient conditions may trigger oxidation reaction.

It is precisely because of these dangerous properties of acetone that its storage requirements are particularly important.

ACETONE STORAGE ENVIRONMENTAL REQUIREMENTS

According to China's list of hazardous chemicals and relevant storage standards, the storage environment of acetone needs to meet the following requirements:

1. Storage place

Acetone should be stored in a cool, well-ventilated, dedicated warehouse away from fire sources. The storage warehouse should be equipped with fire prevention, explosion-proof, sun protection, moisture-proof, lightning protection and other facilities to ensure that acetone will not cause danger due to changes in the external environment.

2. Temperature control

The flash point of acetone is low, so the temperature of the storage environment should be controlled at a low level. It is usually required that the storage temperature does not exceed 30°C to avoid high temperature causing acetone volatilization or spontaneous combustion.

3. Keep away from fire and oxidant

The storage place of acetone should be away from fire source, heat source and oxidant. Avoid mixing with other hazardous chemicals that may cause reactions, such as strong oxidants and acidic substances.

ACETONE STORAGE SAFETY MEASURES

In addition to environmental requirements, the storage of acetone requires a series of safety measures to ensure its safety during storage.

1. Anti-leakage measures

Acetone storage containers should have good sealing performance to prevent liquid leakage. Storage sites should be equipped with leak-proof trays or cofferdams to quickly collect and dispose of spills in the event of a leak.

2. Anti-static measures

Acetone is prone to static electricity during storage and handling, so anti-static measures need to be taken. For example, use of an anti-static container, grounding equipment, installation of a static eliminator, or the like.

3. Ventilation measures

Due to the strong volatility of acetone, the storage site should have a good ventilation system to ensure that the concentration of acetone vapor in the air will not reach the explosion limit. The concentration of acetone in the air should be checked regularly to ensure that it is within a safe range.

Acetone storage packaging requirements

According to the China List of Hazardous Chemicals, the storage packaging of acetone is also subject to specific requirements:

1. Special container

Acetone should be stored in a special metal or plastic container, the container should have corrosion resistance, high temperature resistance, pressure resistance and other properties. Galvanized iron drums or polyethylene plastic drums are usually used as storage containers.

2. Clear identification

The storage container shall be clearly marked with "Acetone" and marked with the identification of dangerous goods. The container should also be marked with production date, batch number, net content and other information.

3. Sealing performance

The sealing performance of the container is a key factor in the storage of acetone. Make sure the container lid is tight to prevent leakage or volatilization.

Acetone storage considerations

1. Periodic inspection

The storage site should regularly check the tightness of the container, the operation of the equipment and the integrity of the safety facilities. Found that the problem should be dealt with in a timely manner to avoid accidents caused by negligence.

2. Emergency plan

The place where acetone is stored shall formulate emergency plans, be equipped with fire extinguishers, gas masks, protective clothing and other emergency equipment, and organize employees to conduct emergency drills on a regular basis.

3. Training and Management

Enterprises that store acetone should conduct regular safety training for employees to ensure that employees are familiar with the hazardous characteristics of acetone, storage requirements and emergency disposal methods.

Summary

As a flammable and volatile hazardous chemical, the storage requirements of acetone should be strictly in accordance with the list of hazardous chemicals in China and relevant laws and regulations. From storage environment, safety measures to packaging requirements, every link needs to be taken seriously to ensure the safety of acetone during storage. Only in this way can we effectively avoid accidents caused by improper storage, ensure the safety of personnel and property, and also meet the requirements of relevant national laws and regulations.
