I keep citing sites for writing “OK” with no ppm or time on sanitizer checks at the three-compartment sink and on line buckets. For compliance, record actual concentration per label/local code (commonly 200–400 ppm quats or 50–100 ppm chlorine) at setup and at least every 4 hours, using unexpired test strips and noting the time. If you want it, I can share a one-page log template I use during inspections that aligns with what we verify.
Same pain here — after an ‘OK’ citation we hung a laminated one-pager by each 3-comp and line bucket and set a repeating 4-hour Quat o’clock alarm so the crew writes ‘ppm + time,’ plus we Sharpie the test-strip vial with the open date. Small caveat: some jurisdictions want line buckets checked every 2 hours and our chlorine label targets 75 ppm, so double-check your product and local code.
We printed the target range right on the log and have the crew write it as “ppm @ time,” so entries look like “300 ppm @ 9:10” instead of “OK.” The little hack that stuck was Velcro-ing the test-strip vial to the 3-comp and dating it so they’re using “unexpired test strips.” Small caveat: quats can read weird in hot water, so we test after the water sits a minute.
Quick tweak that helped us: we added a tiny “contact time” blank and a corrective-action checkbox to the log, so entries look like “320 ppm, 60s, 9:10,” and if it’s low they tick “remade” and initial — kept our inspector from playing ppm detective. @elena_t98 small caveat: with quats, towels can drag it down fast, so we recheck right after the first towel dunk instead of waiting 4 hours.
