Community supermarket backroom manager - cold room daily SOP; temperature logged twice a day, door-open time capped, no activity during defrost, raw/cooked/wet/dry stored apart. One person runs the room by the sheet

You are a cold-room advisor for a community
supermarket. Write an archivable Cold Room
Daily SOP meant to hang on the room's door.
Context, stated up front: [number of rooms]
small commercial cold rooms, no dedicated
attendant; the backroom manager also handles
receiving and stocking. So the design premise
is "every line costs a minute or two" -
anything needing a dedicated block of time
gets abandoned by day three.

1. Temperature (two logs a day, times fixed)
- Log at: once before opening, once at
  evening closeout, on the sheet on the
  door (pen hangs beside it)
- Log what: displayed temperature / time /
  initials - three boxes, one minute
- Trip criteria fixed:
  cooler reading above [cooler limit]°C,
  freezer above [freezer limit]°C - no
  deliberation, three immediate actions:
  move goods away from the fan discharge,
  notify the store manager, hang the
  "equipment check" tag. Repairs route to
  maintenance; the backroom manager never
  disassembles anything
- Reading within limits but the sheet shows
  [gap warning] consecutive empty slots -
  that counts as not recorded, which counts
  as not done

2. Door (time caps)
- Picking: done within [single-open cap]
  minutes; if one trip won't do it, close
  the door, count ten seconds, reopen -
  never prop it and run back and forth
- Continuous work (receiving, counting):
  past [continuous-work cap] minutes,
  switch to batch moves - carry five cartons
  out, close the door, repeat; never work
  with the door held open
- Prohibited: anyone wedging the door with
  goods or crates - the goods doing the
  wedging get booked as that day's spoilage;
  writing this into the SOP is what lets
  staff enforce it

3. Defrost and equipment windows (what
   stops)
- During defrost (check the defrost timer
  or ask maintenance; usually a fixed
  window): no receiving, no counting, no
  long door openings - defrost already has
  the temperature climbing; add traffic and
  the goods take a double hit
- Fan noise, floor ice thicker than a coin,
  door gasket frost-hardened - log it on
  the door's repair board and report that
  day; do not wait for the breakdown

4. Zoning (what never shares a shelf)
- Three hard lines:
  Raw versus ready-to-eat: direct-consumption
  items (tofu products, prepared foods) never
  share a level with raw meat and seafood;
  fixed labeled levels for each
  Wet versus dry: dripping goods (thawing
  meat, washed produce) go on the bottom
  level with a drain tray, never above
  anything
  Odor: seafood in its own compartment or
  containers, never sharing with dairy
- Stacking: [clearance] cm off walls, pallets
  off the floor, nothing blocking the fan
  outlet, no stacks above [stack cap] levels
- FIFO in the cold room, made physical: a
  new lot of the same item goes behind or
  under the old lot - the rule "new stock
  never enters the front row" beats ten
  FIFO training sessions

5. One fixed weekly action (ten minutes)
- [Fixed weekday] after evening closeout:
  sweep the floor of the room - move pallets,
  check for crushed stock underneath, wipe
  the door gasket once, reconcile the
  temperature sheet for gaps and countersign
- Near-expiry items found route to the
  clearance process on the spot, without a
  round trip out of the room and back

Forbidden:
- No "keep the cold room clean and tidy" -
  every line carries a number, a time, and
  an action
- No "report anomalies promptly" - "promptly"
  becomes "log on the repair board today"
- No equipment brands or models; the words
  are "cooler," "freezer," "fan"
- Two pages maximum; readable while standing
  at the door

Why it is written this way

The whole design bends around one reality: the small cold room's manager is not dedicated, and any clause requiring "a set-aside block of time" dies within three days. So the skeleton is not "a complete cold-storage management system" but "two moments a day, one action a week" - one minute of temperature logging morning and evening, ten minutes of floor-sweeping on Sunday night. Pinning management actions to fixed clock points comes closer to the full set of execution conditions than a page of policy ever gets: fixed times make fixed actions, and fixed actions make continuous records.

The temperature trip criteria are hard-coded as "above X degrees, do three things," because the backroom manager's real difficulty at an over-limit reading is not knowing it's high - it's not knowing what to do or how urgent it is: move goods off the fan discharge (the fastest cooling move), notify the manager (escalation), hang the tag (prevention). Three actions, one minute, zero judgment required - the SOP's job is front-loading all the judgment so the floor only executes.

The door section deliberately includes the hard line "goods wedging the door get booked as that day's spoilage": door-propping is the cold room's most common slow suicide - everyone has done it, everyone thinks "just a moment." But unless the rule puts a price on that moment, it stays a habit nobody dares mention. Likewise "no receiving during defrost" blocks the double hit: defrost already has the temperature climbing; add door traffic and both the compressor load and the goods' temperature swing are taken for nothing.

The three zoning lines (raw/cooked, wet/dry, odor) are written as shelf-level physical rules rather than hygiene principles, because "watch for cross-contamination" produces zero actions. "New stock never enters the front row" is the most valuable line in the document: it converts FIFO from a matter of personal discipline into a matter of room layout - people only have to put things where the sheet says, and the sequence comes out right by itself.
