In the context of hazardous-waste management, infectious wastes are materials that pose a biological risk to human health and the environment. These materials typically originate from hospitals, clinics, and biological research facilities.12
Common examples of infectious medical materials include:
- Used bandages: Dressings and materials contaminated with bodily fluids.1
- Hypodermic needles: Sharp objects used in medical procedures.1
- Sharps: Disposable syringes and other puncture-prone objects.2
- Laboratory waste: Materials generated during research or diagnostic testing that may contain infectious agents.12
- Glassware and metallic implants: Items that may be contaminated during clinical use.2
Proper management of these materials is essential to prevent the spread of disease. Facilities are generally required to segregate this waste at the source using specific containers—such as puncture-proof boxes for sharps—to ensure safe handling, storage, and transport for professional treatment.2
