Hazardous Waste

Hazardous waste refers to any material that poses a substantial threat to human health or the environment. This can include chemicals, solvents, pesticides, heavy metals, and other materials that are harmful if not properly handled and disposed of.

Characteristics of Hazardous Waste

Ignitability: Waste that can easily catch fire, such as solvents and certain types of chemicals.
Corrosivity: Waste that can corrode or eat away at materials, such as acids or bases with high pH levels.
Reactivity: Waste that is unstable and can react violently with other substances, potentially causing explosions or toxic fumes.
Toxicity: Waste that contains harmful chemicals or substances that can cause injury or death when ingested or absorbed.

Proper Handling and Disposal

It's crucial to handle hazardous waste with care to prevent harm to humans and the environment. This includes using appropriate personal protective equipment, following proper storage and labeling procedures, and ensuring safe transportation and disposal methods.

Regulations and Compliance

There are specific regulations and laws governing the management of hazardous waste, such as the Resource Conservation and Recovery Act (RCRA) in the United States. It's important for businesses and industries to comply with these regulations to avoid legal repercussions and protect public health and the environment.

Study Tips
