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 […]

Safer STEM Labs

Like science labs, STEM (science, technology, engineering, and math) labs require safety and security measures, with an emphasis on safety training, personal protective equipment (PPE), standard operating procedures, engineering controls, and supervision. While hand and power tools (e.g., hammers, screw drivers, table saws, drill presses) can be found in STEM labs, many students and teachers […]
