This month's Safety Spotlight focuses on holding students accountable for their safety actions in STEM (science, technology, engineering, and mathematics) labs and makerspaces. Most teachers should understand the importance of a proper safety program. In this article, the author describes his work permit system for safety. The work permit system is fairly simple. After a student passes all of the required safety tests, they are issued a permit dated and signed by the instructor. If the student violates a minor, non-accident-related safety rule (e.g., not wearing safety glasses, throwing an object, horseplay, etc.) they get a hole punched through one of the Xs on their permit. The first hole punched constitutes a warning, whereas the second hole punched results in a teacher detention with parent contact. Three hole punches on the same permit results in the loss of the permit and right to work in the lab, as well as an office referral for further disciplinary action. For major safety violations, the instructor always reserves the right to revoke the student's permit and lab access.
