The requirement that potentially biologically hazardous materials must be treated prior to disposal is driven by the need to minimize risk to human health and the environment. Treatment typically involves procedures that render the materials non-hazardous or significantly reduce their hazard potential. This can include sterilization, incineration, or chemical treatment methods that deactivate any pathogens present in the materials.

Proper treatment is crucial because biologically hazardous materials can include infectious agents, which pose a serious risk if they are simply disposed of without any form of processing. Treating these materials ensures that they are safely managed and do not contribute to environmental contamination or public health issues.

Labeling, burning, or recycling alone do not adequately address the complex safety needs associated with biologically hazardous materials. While labeling is important for identification and safety during handling, it does not mitigate the hazards of the materials. Burning might be a method of treatment but is not always applicable to all types of hazardous materials and could lead to the release of harmful substances if not handled properly. Recycling is generally not appropriate for biologically hazardous materials, as it could further spread contamination. Thus, treatment stands out as the essential step before disposal.
