We started handing a small 3–1-1 card at divest during “peak-hour traffic” and logging secondary-bag checks hourly; it cut liquid alarms about 15% in two weeks and made the training feel real. If staffing’s tight, post the card with a QR to Liquids, Aerosols, and Gels Rule | Transportation Security Administration and have the next shift open with a 60-second reminder so the transition doesn’t stall.

Quick win at our checkpoint: we set a clear acrylic “quart bag” template at divest (about $12) so travelers can test if their items meet the 3.4-ounce/3–1-1 rule during peak-hour traffic, and liquid alarms dropped noticeably within a week. It only works if the first officer in the lane points to it and gives a five-second “everything in the bag” reminder, @A. Torres.

We switched from floor messaging to an eye-level placard over divest that reads “[redacted] (3.4 oz) — one quart bag per person,” and officers point to it while noting it matches international standards. Building on @lisa_montez09, that quick visual nudge boosted compliance without extra back-and-forth — think hotel shampoo, not a sports bottle. Caveat: QR codes on the sign help some, but we keep a laminated explainer for folks without phones.
