IATA Dangerous Goods Classification Requirements for Air Transport of Styrene?

IATA Dangerous Goods Classification Requirements for Air Transport of Styrene

styrene is an important chemical in the modern chemical industry and is widely used in the manufacture of plastics, resins and fibers. Styrene is classified as dangerous because of its flammability and volatility. In air transport, it is essential to ensure the safe transport of dangerous goods. This article will discuss in detail the IATA (International Air Transport Association) dangerous goods classification requirements for styrene in air transport to help relevant personnel understand how to transport compliance.

PHYSICOCHEMICAL PROPERTIES OF STYRENE

Understanding the basic properties of styrene is the basis for the classification of dangerous goods. Styrene, chemical formula C, H, is a colorless liquid with a slightly aromatic odor. Its boiling point is 145°C and melting point is -51°C. It is easy to volatilize at room temperature and form flammable vapor. Styrene has a flash point of 31°C, meaning that above this temperature, its vapor is highly flammable when exposed to an open flame.

IATA Dangerous Goods Classification Overview

According to IATA regulations, dangerous goods are divided into 9 categories, and styrene belongs to Class 3 flammable liquids. IATA defines a flammable liquid as a liquid with a flash point below 23°C and an initial boiling point below 35°C, or a liquid with a flash point below 23°C and an initial boiling point above or equal to 35°C. The flash point and boiling point of styrene are in accordance with the conditions of Class 3 flammable liquids, so its transportation needs to follow the corresponding dangerous goods rules.

Styrene IATA Dangerous Goods Classification Requirements

1. Packaging and Containers Requirements: IATA stipulates that styrene must be transported in containers that meet United Nations packaging standards. Packaging materials are rigorously tested to ensure that they do not leak or break during transport. Containers must be labeled with appropriate dangerous goods labels that clearly identify the contents as flammable liquids.

2. Labels and Markings: According to IATA requirements, all dangerous goods packaging must be affixed with IATA uniform dangerous goods label. For styrene, the label shall include the UN number, a hazardous material identifier (e. g. "Flammable Liquid") and a class identification (Class 3). The chemical name or trade name of the substance should also be indicated on the label.

3. Transport documentation requirements: In air transportation, the shipper of dangerous goods must provide detailed transportation documents, including dangerous goods declaration form, safety data sheet (SDS) and cargo consignment certificate. These documents are required to describe in detail the physical and chemical properties of styrene, potential hazards and countermeasures.

Styrene in air transport safety precautions

1. Prevention of leaks: Transport containers for styrene must ensure tightness to prevent liquid leakage. Damage or leakage of any container will cause serious safety hazards, so it must be thoroughly inspected before transportation.

2. Ventilation and storage: Styrene vapor is highly volatile, so the storage environment should be well ventilated. During transportation, avoid mixing styrene with other dangerous goods to prevent accidental reactions.

3. No fireworks: Since styrene vapor is highly flammable, fire sources must be strictly prohibited during transportation. Avoid smoking in the cabin and ensure that all equipment meets explosion-proof requirements.

Summary and Compliance Recommendations

The IATA dangerous goods classification requirements for air transport styrene are strict and detailed, and are designed to ensure safety during transportation. Shippers and carriers must be fully aware of these requirements to avoid violations and potential safety hazards. Regular training of staff, updating of hazardous material transportation knowledge and cooperation with professional logistics companies are key to ensuring compliance. By complying with IATA regulations, transportation risks can be effectively reduced to protect human life and property.
