Visual Controls Quick Reference (Checklist)

Use this one-page checklist when you design or audit visual controls at the point of work.

• Is the visual placed where the decision is made or where the action occurs?
• Is the message clear in under 3 seconds (large type, simple words)?
• Does each color or signal have one unambiguous meaning?
• Does the visual prompt a specific next action (e.g., "Stop and call lead" rather than just "Problem")?
• Is ownership assigned for updates and weekly checks?
• Are critical tools and supplies stored in labeled locations or shadow boards?
• Are status displays updated at a predictable cadence (shift change, end of batch)?
• Is there a simple replacement plan for worn or damaged signs and boards?
• Do visuals align with the standard work documents (same terms, same steps)?
• Is there a short test: observe 5 workers—do at least 4 respond as the visual intends?
