Water hygiene logs with temperatures, thresholds and remedials

Monitoring is what makes a legionella control scheme real. Gaffer logs each reading with its temperature, whether it passed the threshold, the instrument used and that instrument's calibration reference — and tracks any remedial action through to completion.

How water hygiene logs work in Gaffer

A log per reading, against a site and location, with the remedial loop closed rather than noted.

Pass or fail, against a threshold

Each reading records the temperature or sample result and whether it passed the threshold, so a failing outlet is unmistakable in the record.

The instrument is traceable

The instrument used and its calibration reference are stored with the reading. A temperature from an uncalibrated probe is not evidence, and this is how you show it was not.

Remedials tracked to done

Where a reading fails, the remedial action, its due date and its completion date are recorded — so failures close out instead of accumulating.

What you get

Water hygiene logs sit alongside legionella assessments and calibration records in one platform.

  • Log reference, site name and the specific location or outlet
  • Reading type, date and time recorded per entry
  • Temperature in °C and sample result captured as values
  • Explicit passed-threshold decision on every reading
  • Instrument used plus its calibration reference for traceability
  • Remedial required, due date, action taken and completion date
  • Linked to the customer and the site's legionella risk assessment

Common questions about water hygiene logs

What temperatures should I be recording?

HSG274 generally expects hot water to reach 50°C at the outlet within a minute (55°C in healthcare) and cold to stay below 20°C. Gaffer stores the measured value and the pass/fail against your threshold rather than assuming one standard, because the target depends on the system and the setting.

Why does the instrument calibration reference matter?

Because a reading is only as trustworthy as the probe that took it. If a thermometer is later found to be out of calibration, being able to see which readings it produced is the difference between a contained problem and requestioning everything.

Can I show a customer their monitoring record?

Yes. Logs are recorded against the customer and site, so a landlord or facilities manager can be given the monitoring evidence for their premises to support their own duty-holder obligations.

Does a failed reading create a follow-up?

The log records that a remedial is required, its due date and when it was completed, so outstanding remedials are visible rather than being a note in a comment field.
