Reactive waste refers to materials that can undergo rapid chemical reactions, potentially causing explosions, fires, or the release of toxic gases when exposed to air, water, or other substances. This type of waste is often generated in industrial processes, laboratories, and certain manufacturing activities. Proper handling and disposal are crucial to prevent hazardous situations. Common examples of reactive waste include sodium, potassium, and certain types of acids and peroxides. These materials require special storage conditions and must be treated according to strict regulations to ensure safety and environmental protection.
