Which waste category includes flammable and explosive substances?

The category that includes flammable and explosive substances is hazardous waste. Hazardous waste is specifically defined by characteristics that can pose a risk to human health and the environment. These characteristics include toxicity, ignitability (flammability), reactivity (which includes explosiveness), and corrosivity.

Flammable substances have the potential to easily ignite under certain conditions, while explosive substances can rapidly release energy resulting in an explosion. Both of these properties classify materials as hazardous due to the dangers they present if not managed properly. Proper identification and management are crucial in preventing accidents and ensuring compliance with environmental regulations.

In contrast, municipal waste primarily consists of everyday items discarded by households and is not defined by the same hazardous properties. Industrial waste, while it can include some hazardous materials, encompasses a broader range of waste products generated by industrial processes, and not all industrial waste is classified as hazardous. Biodegradable waste refers to organic materials that can break down naturally and does not include the dangerous characteristics associated with flammable and explosive substances. Thus, the correct classification for waste that includes flammable and explosive substances is hazardous waste.
