What does Class 2 of the transportation hazard classes cover?

• A. Flammable solids and liquids
• B. Compressed gases and liquefied gases
• C. Corrosive materials
• D. Miscellaneous hazardous materials

Answer: (B)

Class 2 of the transportation hazard classes specifically addresses compressed gases and liquefied gases. This classification encompasses a variety of substances, including those that are flammable, non-flammable, or toxic when they are in gas form.

Compressed gases are defined as gases that are kept at a pressure that can lead to hazards upon release, such as rapid expansion or explosion. Liquefied gases are those that are normally gaseous but can be transformed into liquids under pressure. The importance of this classification lies in the need for specific handling and transportation protocols to minimize risks associated with these types of materials, which can pose dangers such as fire, explosion, and asphyxiation if not managed properly. Understanding this classification is crucial for ensuring safety during the transport of hazardous materials.
