Joining the sanitation schedule to the maintenance schedule

In a food plant, the master sanitation schedule, the maintenance schedule and the quality records are usually three separate systems owned by three teams. Audits find the seam between them, because that is where evidence goes missing and where contamination risk actually lives.

Why the seam matters

Maintenance work on production equipment creates contamination risk: tools, lubricants, debris, disturbed surfaces, people in an area they do not normally enter. The control is a post-maintenance clean and a verification before the line restarts. If maintenance and sanitation are in different systems, that handover depends on somebody remembering.

Make the clean part of the maintenance job

The simplest fix and the most effective: a maintenance job on food contact equipment does not close until the post-maintenance sanitation step is completed and verified, by name, with a photograph. One record, one sequence, no handover to forget.

Put periodic sanitation on the same schedule as periodic maintenance

Daily cleaning happens because production cannot start without it. The periodic work is where slippage hides, and it is exactly the kind of work a maintenance schedule is good at holding.

• •Overhead structures, beams and pipework
• •Drains, and the equipment around them
• •Wall and floor junctions, and anywhere water sits
• •Inside equipment guards, frames and hollow sections
• •Compressed air lines and filters
• •Dust collection and extraction
• •Cold store evaporators and condensate trays

Record the verification, not just the clean

The clean is a task. The verification is the evidence: visual inspection, swabs, ATP results, whatever your programme specifies, with the result as a number and the name of who took it. A schedule showing cleans completed with no verification results is the record that gets challenged.

Lubricants and materials need to be controlled at the job

Food-grade lubricant used on food contact equipment is a control that fails at the point of use, when somebody grabs the nearest grease gun. Record which lubricant was used, on which equipment, as a step in the job, and hold the approved list where the technician is rather than in a quality manual.

The audit question to rehearse

Pick a piece of equipment and a date, and produce: what maintenance was done, who did it, what was cleaned afterwards, who verified it and what the result was. If that takes more than a few minutes, or requires two systems and a phone call, the seam is where your next non-conformance comes from.
