STEM classrooms are filled with energy, curiosity, and hands-on discovery—but they also contain hazards that must be carefully managed. In this Safer Ed episode, we break down the three main categories of lab hazards—physical, chemical, and biological—and explore strategies teachers can use to identify and control them.

Through practical examples and proven safety methods, the discussion highlights how preparation, judgment, and a culture of responsibility can keep both students and educators safe.

What You’ll Learn in This EpisodeKey

• The three main hazard categories in STEM labs: physical, chemical, and biological.

• Real-world examples of physical risks often overlooked in classrooms.

• How to use Safety Data Sheets (SDS) to understand and manage chemical hazards.

• Why biological hazards—even simple mold collection—require strict controls.

• The three levels of control: engineering controls, administrative controls, and PPE.

• When to use substitution or elimination to reduce risk altogether.

• Why shared responsibility and teacher modeling are central to building a culture of safety.

Key Takeaway

STEM labs can be safe, engaging, and fun—but only when hazards are identified, risks are assessed, and safety measures are applied at every level. Safety isn’t just a rulebook—it’s part of the learning experience.
