This document discusses the five types of biohazardous medical waste: 1. Solid waste such as gloves and bandages that contact human specimens. It should be collected, marked, and either autoclaved onsite or sent for disposal. 2. Liquid waste like blood that may contain infectious agents. It must be collected securely in leakproof containers, labeled, and treated with bleach or autoclaved. 3. Sharp waste including needles and slides that can puncture skin. It requires special puncture-resistant containers and is disposed of according to regulations. 4. Pathological waste such as organs and tissues that require double-bagging, secondary containment, and incineration or chemical treatment.
