End-of-shift cleaning acceptance checklist - seven zones, action-plus-checkable-result criteria, cleaners never sign off their own zone

You are the cleaning supervisor at a central kitchen. I
need an end-of-shift cleaning acceptance checklist: zone
by zone, every shift, every criterion phrased as an
action someone can perform to check - never "cleaned
properly" and its family of adjectives.

Seven zones (following my plant's flow; add or remove):
locker & handwash / wash & prep / cooking / portioning /
packing / dishroom / trash holding & perimeter

Criterion phrasing per zone (the standard):
- Every line = action + checkable result. Examples:
  "Floor drain: grate lifts out; channel wall slick-free
  to the touch; no settled debris" - not "drain clean"
  "Under equipment: flashlight sweep; no standing water,
  no dropped raw material" - not "no dead corners under
  equipment"
  "Counter seams: fingernail draw across; no residue in
  the seam" - not "counters clean"
- Towels and tools: color-coded towels returned to their
  matching color bin; mops hung, never on the floor
- Chemicals: back in the locked cabinet, dilution buckets
  emptied - dilution carried overnight is the origin of
  the next morning's mix-up incident
- Trash room: door closed, floor free of leaking liquid,
  emptied same day or annotated with a hold deadline

Acceptance flow:
- Acceptor: the cleaning supervisor or a designated team
  lead; whoever cleaned a zone never signs it off
- Timing: completed within [30] minutes after shift end
- Three verdicts: pass / fail (rework on the spot,
  re-verify after) / not used today (equipment that ran
  nothing this shift - annotated, which is neither
  uncleaned nor passed)

Output format:
- Main table: zone × criterion × verdict × rework
  deadline
- Appendix 1: daily signature row (acceptor / date /
  rework re-verification result)
- Appendix 2: the "repeat-fail" tracking column - the
  same criterion failing [3] days running in the same
  zone escalates to the plant manager with that
  criterion's week of history attached

Constraints:
- Deep-clean and seasonal projects do not enter this
  checklist - those are weekly/monthly plans; mixed in,
  they would sink the daily acceptance
- No "keep it tidy" / "cleaned in place" items that
  cannot be judged pass or fail
- Cap each zone at [8] criteria; beyond that, split the
  zone or the acceptance timing rather than stuffing
  the list

Why it is written this way

Criteria written as action plus checkable result is the border between a checklist and an argument. Adjectives like "cleaned properly" get interpreted by whoever is standing there, and every dispute in the history of cleaning inspection lives inside an adjective. Replace them with "lift the grate, run a finger along the channel wall, sweep a flashlight underneath," and judgment collapses into procedure - a brand-new acceptor, a visiting client, a third-party auditor all produce the same answer. A checklist's value is not completeness; it is that everyone who executes it agrees on what it says.

Whoever cleans a zone never signs it off - one shift-swap buys the checklist its credibility. Self-inspection survives the slow season and collapses in peak: not a character flaw, just the fact that nobody can find faults in two hours of their own fresh work. Cross-acceptance costs one scheduling move and buys a "pass" that means the same thing every time it is written.

The "not used today" verdict is the state most often forgotten and the one that protects the rest. Facing an idle machine without it, the acceptor has two bad options: pass it (a fabrication - nobody checked) or fail it (rework a clean machine, and the crew learns this list is theater). The third state makes honesty the cheapest option - one law of checklist design worth keeping: never make the truth-teller pay.

The three-day repeat-fail escalation is the highest-value column on the page. A single miss closes with same-shift rework; the information is in the repetition - the same criterion failing daily means the problem is not the person but the time allotted, the tools, or a design that traps soil, and that call sits above the cleaning supervisor's pay grade. Without the column, everyone reworks daily, everyone is busy, and nobody owns the cause.
