The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Record particle counts at the released locations
  2. Inspect HEPA differential pressure
  3. Close the shadow board: every tool accounted for before the article moves
  4. Check garments and airlock practice against the booth procedure
  5. Hold the article if a tool or foreign object is unaccounted for

What Skipping It Looks Like

The booth looks clean, one driver is in a pocket, and the article moves because the schedule said it would.

Setting the interval
