Be Aware of Biohazards

As many high schools begin adopting curricula that include the study of microorganisms, biosafety must be addressed for a safer lab experience.
Biohazards are biologically derived infectious materials, which may present a risk to other living things. Such hazards can enter the body through such places as the eyes, mouth, lungs, and open wounds. Unlike chemical hazards, biohazards can reproduce and spread infection throughout the body. Categories of biohazards include
• human, animal, and plant pathogens: bacteria, fungi, viruses, parasites, rickettsiae, chlamydiae, toxins;
• human and animal blood, blood products, tissues, and body fluids;
• cultured cells and potentially infectious agents within them;
• recombinant DNA products; and
• clinical, necropsy, and surgical specimens (e.g., tissues, fluids).
