Safer Science and Safer STEM labs are vibrant spaces where students explore, experiment, and discover. But as much as they inspire curiosity, they also introduce potential hazards if risks arenโt managed carefully. As discussed in our latest Safer Ed podcast, teachers are not only responsible for meeting learning objectives but also for safeguarding students, colleagues, and themselves from accidents that can range from minor mishaps to serious injuries.
Recognizing Red Flags
Some dangers are clear-cut. Outdated materials such as alcohol fuel burners, methanol, mercury thermometers, concentrated acids and bases, or specimens preserved in formaldehyde have no place in modern Kโ12 labs. Their risks far outweigh any instructional value. Similarly, activities involving biological samples, like collecting saliva, blood, or bacteria culturesโexpose students to unnecessary pathogens and should be avoided.
From Awareness to Action: The โAAAโ Framework
Safety begins with awareness, spotting unlabeled containers, unsafe equipment, or aging supplies. However, awareness alone isnโt enough. The Safer Ed podcast highlights the โAAAโ method: Hazard ANALYSIS, Risk ASSESSMENT, and Safety ACTION.
-
Hazard ANALYSIS: Identify potential hazards in the planned activity.
-
Risk ASSESSMENT: Determine what could realistically go wrong and the consequences.
-
Safety ACTION: Choose the best strategies to prevent accidentsโengineering controls (like ventilation or eyewash stations), administrative controls (clear protocols and training), personal protective equipment, or even eliminating or substituting materials.
Six Intentional Practices for Prevention
The episode also outlines six intentional steps teachers can take to prevent accidents before they happen:
-
Review Safety Data Sheets (SDS) for all chemicals.
-
Inspect equipment and materials before use.
-
Review procedures carefully, including waste management.
-
Conduct a test run of new or unfamiliar experiments.
-
Substitute safer alternatives whenever possible.
-
Always weigh educational value against risk.
These practices arenโt extra workโtheyโre professional preparation. They help build confidence and ensure safety isnโt an afterthought in STEM instruction.
Building a Culture of Responsibility
Lab safety isnโt just about students. Teachers, paraprofessionals, and staff are also at risk if hazards are ignored. In fact, educators can face liability if unsafe practices lead to harm. Creating a culture where teachers intervene when they see unsafe activities and where safety is integrated into lesson designโprotects everyone and models responsibility for students.
The Takeaway
Safer labs are productive labs. By recognizing hazards, assessing risks, and implementing thoughtful safety actions, teachers can balance exploration with protection. As the Safer Ed podcast reminds us, safety isnโt a barrier to learningโitโs part of the learning process itself.
