What does Class 2 cover in transportation hazards?

• A. Flammable and combustible liquids
• B. Compressed gases and toxic gases
• C. Explosives and solids
• D. Oxidizers and corrosives

Answer: (B)

Class 2 in the context of transportation hazards specifically pertains to compressed gases, which includes both non-flammable and flammable gases, as well as toxic gases. This classification is essential for safety regulations and handling procedures during transport, as it addresses the potential dangers associated with gases under pressure.

The distinction of Class 2 emphasizes the importance of understanding the characteristics of gases that can pose risks, such as being flammable or toxic upon release. This knowledge is vital for first responders and individuals involved in the transportation of such materials to ensure proper precautions and emergency response measures are effectively implemented.

The other classifications focus on different materials: flammable and combustible liquids belong to Class 3, explosives and solids fall under Class 1, and oxidizers and corrosives are categorized as Class 5 and Class 8, respectively. Understanding these classifications helps in identifying suitable measures to mitigate risks during transportation.
