Hey team—quick pre‑lab reset. Sixty seconds to make Future You proud. First, the floor. Do a slow sweep with your eyes—and your shoes. Any screws, scraps, or sneaky puddles? Nudge ’em to the bin or wipe them now. Clear floor, calm brain. Cords and air lines next. Follow each one from source to tool. Any tangles, trip lines, or hissing? If it looks like spaghetti, untwist it. If it sounds like snakes, flag it. PPE check. Glasses on and clean? Lab coat fastened? Gloves handy? Hair tied back, jewelry tucked. If you’d head-bob through a doorway without catching on anything, you’re golden. Spill kit—point to it. Yup, actually point. Read the label in your head. Could you reach it in ten seconds? Good. Egress path: look to the exit. If something went sideways, could you walk straight out without hopscotch? Clear any blockers now. Now, say this out loud: “Today, my housekeeping commitment is…” Fill in one specific thing. Maybe “coil hoses after each use,” or “wipe benches between steps,” or “keep lids on when not pouring.” Your turn—say it. Quick recap: floor clear, cords tidy, PPE on, spill kit spotted, exit open. You’re set. Safe space, sharp focus. Make the science exciting—and the safety boring. You’ve got this.
