IATA Dangerous Goods Classification Requirements for Air Transport of n-Butyl Acrylate?

IATA Dangerous Goods Classification Requirements for Air Transport of n-Butyl Acrylate

in the modern chemical industry, n-butyl acrylate, as an important chemical raw material, is widely used in coatings, adhesives, plastics and other fields because of its good adhesion performance and stability. During air transportation, due to its chemical nature, it may pose a potential risk to transportation safety, so it needs to be managed and transported in accordance with the relevant dangerous goods classification requirements of the International Air Transport Association (IATA). This article will analyze in detail the IATA dangerous goods classification requirements for the air transportation of n-butyl acrylate to ensure the safety and compliance of the transportation process.

Physical and Chemical Properties of 1. n-Butyl Acrylate

n-Butyl acrylate is a colorless or pale yellow liquid with a pungent odor. Its molecular formula is C≡H≡C and its molecular weight is 130.16. The main physical and chemical properties of butyl acrylate include:

• flash Point: approx. 30°C (closed cup)
• boiling Point: about 180°C
• density: about 1.04g/cm³
• solubility slightly soluble in water, but miscible with organic solvents.

These properties determine the possible danger of n-butyl acrylate during transportation, especially under high temperature or open flame conditions, and its volatility and flammability may lead to fire or explosion risks.

Risk assessment of 2. n-butyl acrylate

according to international regulations and standards, the classification of dangerous goods is mainly based on their physical, chemical and toxic properties. Hazardous properties of n-butyl acrylate that may be involved during transport include:

1. flammability: n-Butyl acrylate has a low flash point, indicating that it is easy to be ignited at room temperature. According to the IATA Dangerous Goods Classification Standard, flammable liquids are classified as Class 3 dangerous goods.
2. Corrosion: n-Butyl acrylate may have a corrosive effect on metals and other materials, especially under humid or high temperature conditions.
3. Reactivity under certain conditions, n-butyl acrylate may react with other chemicals, releasing toxic gases or creating a risk of combustion.

Based on the above characteristics, n-butyl acrylate is classified as a flammable liquid and belongs to category 3 of the IATA Dangerous Goods Classification.

3. IATA Dangerous Goods Classification Requirements

according to the IATA Dangerous Goods Rules (Dangerous Goods Regulations, DGR), the transport of dangerous goods must follow strict classification, packaging, labeling and declaration requirements. The following are the main requirements to be observed when transporting n-butyl acrylate by air:

1. classification confirmation:

• identify the hazard class of n-butyl acrylate. Based on its flash point and flammability, n-butyl acrylate is classified as a Class 3 flammable liquid.

1. Packaging Requirements:

• use packaging containers that comply with IATA standards. Generally, Class 3 flammable liquids should be packaged in metal or high-density polyethylene containers to ensure the tightness and strength of the containers.
• Packaging containers should be clearly marked with "flammable liquid" (Flammable Liquid) warning labels.

1. Labeling requirements:

• post a DGR-compliant hazardous material label on the outside of the package containing the following information:
  • hazard category (Class 3 flammable liquids).
  • UN number (UN number).
  • Transport-specific name (e. g. n-butyl acrylate).
  • CAS Number.

1. Transport Documents:

• prepare complete documentation for the transport of dangerous goods, including:
  • dangerous Goods Declaration Form (Dangerous Goods declaration Form).
  • Safety Data Sheet (Material Safety Data Sheet, MSDS).
  • Description of the goods (including quantity, packaging, hazard category, etc.).

1. Operational Requirements:

• during the handling and transportation process, ensure that the operators have received special training in the transportation of dangerous goods.
• Avoid mixing and transporting n-butyl acrylate with other dangerous goods, especially substances that may trigger reactions such as oxidants and alkaline substances.

Matters needing attention in 4. air transportation

when transporting n-butyl acrylate by air, in addition to complying with IATA's classification and packaging requirements, the following should also be noted:

1. temperature control:

• n-Butyl acrylate is easy to volatilize at high temperature, so proper temperature control measures should be taken during transportation to avoid direct sunlight and high temperature environment.

1. Ventilation requirements:

• during loading, unloading and transportation, ensure that the area where the goods are located is well ventilated to prevent the volatile n-butyl acrylate from reaching a flammable concentration in the air.

1. Emergency preparedness:

• equipped with appropriate emergency equipment, such as fire extinguishers and protective equipment to deal with possible transportation accidents.

5. Summary

the IATA Dangerous Goods Classification requirements for the transport of n-butyl acrylate by air cover several aspects, including risk assessment, packaging, labeling and preparation of shipping documents. Only strict compliance with these requirements can ensure the safety and compliance of the transportation process. For those in the chemical industry, understanding and mastering these requirements is not only compliance with regulations, but also responsible for transportation safety and environmental protection. Through scientific classification, standardized packaging and strict operation, transportation risks can be minimized to ensure the safe operation of air transportation.
