EcoLab: 3-comp sink sanitizer protocol

ops #ecolab #sanitation #all-staff

The 3-compartment sink is the manual sanitation system. We use it for any item too big for the dishwasher, and as backup if the dishwasher is down.

The three compartments

  1. Wash — hot water + Dish Solid detergent. Scrub.
  2. Rinse — clean hot water. Rinse off detergent.
  3. Sanitize — cool water + QSan concentrate at 150-400 ppm. Submerge for 30 seconds minimum.

Setup (every shift, every change of water)

  • [ ] Fill compartment 1 with hot water (110-130°F)
  • [ ] Add Dish Solid per dispenser (usually 1 pump per fill)
  • [ ] Fill compartment 2 with clean hot water
  • [ ] Fill compartment 3 with cool water
  • [ ] Add QSan from the wall dispenser — 1 pump per 3-gallon fill
  • [ ] Test concentration — must read 150-400 ppm
  • [ ] If below 150 ppm: add another pump, retest
  • [ ] If above 400 ppm: drain some water, refill, retest

During use

  • [ ] Test compartment 3 every 2 hours of active use OR after washing any heavy load
  • [ ] Replace water in compartment 1 (wash) when visibly dirty
  • [ ] Replace water in compartment 3 (sanitize) when concentration drops below 150 ppm after re-dosing

Air-dry only

  • [ ] Items removed from compartment 3 go straight to the drying rack
  • [ ] DO NOT towel-dry (defeats the sanitation)
  • [ ] Allow at least 30 minutes to air dry before stacking

Why this matters

The sanitizer kills pathogens that scrubbing can't remove. Cold-water QSan at correct concentration is FDA-approved for food contact surfaces. Hot water alone is NOT sanitation; it's cleaning. Both steps are required.

Log

Concentration readings logged on the food safety log at open, after every 2 hours of use, and at close. DOH will check this log.
