Which of the following materials requires special management to avoid being disposed of as hazardous waste?

The correct answer encompasses the fact that all the listed materials—scrap metal, scrap tires, and used batteries—require special management to prevent them from being improperly disposed of as hazardous waste.

Scrap metal, while often recyclable and not always considered hazardous on its own, can become hazardous if it is coated with or contains hazardous materials such as heavy metals or other toxic substances. Therefore, proper management practices are vital to ensure that any hazardous substances are addressed before disposal.

Scrap tires are another category that requires special management due to their potential environmental impact. Tires can accumulate water, which becomes a breeding ground for mosquitoes and can lead to other pest-related issues. Additionally, improper disposal of tires can lead to fires that are difficult to extinguish and may produce hazardous smoke.

Used batteries, particularly lead-acid batteries, contain heavy metals and acids that can leach into the environment if not disposed of correctly. Special management, including recycling and proper disposal, is essential to mitigate the risk of environmental contamination and health hazards associated with incorrect disposal practices.

Overall, recognizing that all these materials have the potential to pose risks and require careful handling underscores the significance of the correct management practices to prevent hazardous waste disposal.
