What are the safety regulations for air transport of acetic acid?

Acetic acid (chemical name acetic acid, CH3COOH) is a liquid acid widely used in chemical, food and pharmaceutical industries. Due to its corrosive, flammable and volatile nature, there are strict requirements for the safety of acetic acid in air transport. This article will analyze the safety specifications of acetic acid air transportation in detail to help related enterprises and transportation personnel to ensure the safety of the transportation process.

1. Properties and Hazard Analysis of Acetic Acid

before discussing the air transport safety regulations of acetic acid, it is necessary to understand the basic properties of acetic acid and its potential hazards. Acetic acid is a colorless or slightly yellowish liquid with a strong pungent odor. It has the following key properties:

• acidic: Acetic acid is a weak acid that can react with metals and oxides and is corrosive.
• Flammability: Acetic acid is volatile in the air. After the vapor formed is mixed with the air, it may cause combustion or explosion when encountering a fire source.
• Volatile: Acetic acid has a certain volatility at room temperature and is easy to form a flammable mixture.

Due to these properties, acetic acid is regarded as a dangerous goods in air transportation, and special attention should be paid to the safety issues during packaging, handling and transportation.

2. Classification of dangerous goods in air transport

according to the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA), dangerous goods are classified into nine categories. Acetic acid is generally classified as a Class 3 flammable liquid because of its flammability. The following are the key points of acetic acid in the classification of dangerous goods:

• UN No.: The UN No. 1772.
• Transport identification in air transport, acetic acid must be labeled with an appropriate dangerous goods label, such as a "flammable liquid" label.
• Packaging Requirements: According to the dangerous goods transportation rules, acetic acid must use packaging materials that meet the regulations to ensure that it will not leak or break during transportation.

3. Packing requirements for air transportation of acetic acid

packaging is one of the key factors in the safety of air transportation of acetic acid. Because acetic acid is corrosive and volatile, the choice of packaging material is critical. The following are the main requirements for acetic acid transport packaging:

• material selection: The packaging material must be corrosion-resistant and able to withstand the chemical properties of acetic acid. Common packaging materials include acid-resistant stainless steel, polyethylene (PE) and polypropylene (PP).
• Label and Identification each packaging container must be clearly marked with "acetic acid" and its chemical name, as well as dangerous goods labels and emergency treatment instructions.
• Tightness: The packaging must have good sealing to prevent leakage. Especially during flight, leakage of acetic acid may cause corrosion or other safety issues.

4. Code of Practice in Air Transport

in the process of air transportation, in addition to packaging requirements, operating specifications are also an important part of ensuring safety. The following are the key considerations in the operation of air transportation of acetic acid:

• loading and unloading operations: When loading and unloading acetic acid, special loading and unloading equipment must be used to prevent the packaging container from being squeezed or collided. Operators should wear protective equipment such as protective gloves, goggles and respirators.
• Temperature control: Acetic acid is volatile at high temperatures, so high temperature environments should be avoided during transportation. At the same time, acetic acid should also be prevented from being exposed to low temperatures for a long time, so as not to affect its quality.
• Airline approval airlines transporting acetic acid must be qualified for the transport of dangerous goods and approved by the relevant management department.

5. Safe storage and emergency treatment of air transport

although various safety measures have been taken during transportation, in order to deal with possible accidents, detailed safe storage and emergency treatment plans still need to be formulated.

• Safe storage: During transportation, acetic acid should be stored in a well-ventilated area, away from fire sources and oxidants. Transport vehicles should be equipped with fire extinguishing equipment and ensure good ventilation conditions.
• Emergency treatment: If a leak or accident occurs, the operator should immediately take emergency measures, such as using appropriate adsorption materials to absorb the leak, and promptly contact a professional team for treatment. At the same time, avoid mixing acetic acid with water to avoid splashing or producing more dangerous substances.

6. Summary and Prospect

as an important chemical raw material, acetic acid has a wide range of applications in air transportation. Its danger also puts forward higher requirements for transportation safety. By understanding the nature of acetic acid, dangerous goods classification, packaging requirements and operating specifications, the safety risks during transportation can be effectively reduced.

In the future, with the continuous development of air transportation technology, the safety regulations for the transportation of dangerous goods will be more stringent. Enterprises and transportation personnel need to pay close attention to the changes of relevant laws and regulations, and constantly improve their own safety management level to ensure the safety of air transportation of acetic acid.

Air transport safety specification of acetic acid is a complex and important subject. Through scientific management, standardized operation and advanced technology, it can effectively guarantee the safety of acetic acid in the process of air transportation and provide strong support for the development of related industries.
