Safety Inspection

High-Energy Exclusion Verification

The factory's worst misuse of a CMMS is a general work order that reads like permission to pressurize, load cryogen, or transfer propellant. This inspection exists to prove that path is closed.

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. Confirm pressure, cryogen and propellant work is impossible to start from a general work order
  2. Verify exclusion zones and permits are named on the stand, not remembered
  3. Check that relief devices and vents are tagged and in date, with the system depressurized
  4. Confirm the people badged for the stand match the permit roles
  5. Any request to load, proof or fire an article stops here and opens a permitted work order

Why This PM Exists

The factory's worst misuse of a CMMS is a general work order that reads like permission to pressurize, load cryogen, or transfer propellant. This inspection exists to prove that path is closed.

What Skipping It Looks Like

Permits live in someone's head. The stand has no named exclusion. A helpful technician treats a proof as maintenance because the gauge was already on the work order.

Setting the interval

Monthly. Any request to load, proof, or fire an article stops and opens a permitted work order against the released procedure.
