What must be done with hazardous materials before disposal?

Before disposing of hazardous materials, it is essential that they are properly characterized and packaged. This process ensures that the materials are identified correctly, which includes recognizing their chemical composition and potential hazards. Proper characterization helps in understanding how these materials may react during storage or disposal, which is critical for both safety and compliance with regulations.

Packaging is equally important, as hazardous materials must be contained in suitable containers that can prevent leaks and exposure. This step involves selecting appropriate materials that can withstand the characteristics of the hazardous substances, such as their corrosiveness, flammability, or reactivity. Following these procedures not only protects those handling the materials but also minimizes environmental risks and ensures compliance with legal disposal regulations. Properly characterized and packaged hazardous materials are easier to manage and transport safely to disposal sites, which is a key aspect of responsible waste management.

In contrast, incineration and indefinite storage, while they may be applicable in certain contexts, do not universally address the necessary steps for all types of hazardous waste disposal. Additionally, transporting materials without proper packaging poses severe safety risks and can lead to regulatory violations.
