Which of the following is a common class of hazardous materials?

Flammable liquids are classified as a common class of hazardous materials due to their ability to ignite and burn easily under normal conditions. This classification includes substances like gasoline, alcohol, and other solvents that can pose serious fire hazards. Understanding this classification is crucial for anyone transporting hazardous materials, as it requires adherence to specific safety regulations and guidelines to mitigate risks associated with fire and explosions.

Household goods, while they can sometimes contain flammable or hazardous items, are not classified as a singular class of hazardous materials in the same way that flammable liquids are. Non-hazardous waste and regular food items do not fall under hazardous materials categories, as they are generally considered safe for handling and do not present the same risks that flammable liquids do. Recognizing and categorizing materials correctly is essential for maintaining safety in transportation and storage.
