Quick answer
Plan maintenance or building work before it affects food. Define the work area, stop/protect affected operations, move or securely protect food and agree contractor, isolation and contamination controls. Prevent dust, fragments, chemicals and dirty tools reaching food routes. Reopen affected equipment/areas only after the required safe reassembly, cleaning, checks and documented release; completion of the repair alone is not food-hygiene clearance.
Work can introduce new contamination routes
Drilling, damaged fittings, replacement parts, lubricants and contractor movement can affect food, equipment and clean areas.
SFBB maintenance guidance and physical/chemical contamination guidance support food protection and sound equipment. HSE covers safe competent maintenance in GB.
Agree the work and food-protection plan
| Before/during work | What to record or agree |
|---|---|
| Scope/location | Work boundaries, timing and nearby exposed food routes. |
| Operations | What stops; food/equipment moved or effectively protected. |
| People | Responsible manager, competent contractor and staff communication. |
| Isolation/access | Machine-specific safe energy/access method and controlled area. |
| Contamination | Dust/fragments, chemicals, tools, clothing and waste routes. |
| Unexpected problem | Stop/escalation and potentially affected-food decision. |
| Release | Safe completion, cleaning, checks, authorisation and evidence. |
Keep workers and nearby food operations protected
Use competent people, suitable manufacturer instructions and the required safe isolation/access arrangements. Do not bypass guards or improvise live access for a faster clean/repair.
Separate contractors and dirty tools from food routes. If work cannot be effectively contained, stop the affected operation rather than rely on loosely covered food while debris spreads nearby.
Account for parts, materials and cleaning
Control removed/replacement parts, fixings, blades, packaging and residues. Use materials and lubricants suitable for the intended equipment/food-contact situation.
Remove work waste without contaminating clean areas, then apply the appropriate cleaning/disinfection method. Protect against transfer through vents, drains, hands and equipment contact points as relevant to the work.
Worked example: drilling over an active preparation area
Hypothetical example: a contractor proposes drilling above open ready-to-eat preparation while staff continue beneath the work.
The manager stops and relocates/protects the affected operation under an effective plan. Cleaning the floor afterwards would not establish that uncovered food and equipment avoided debris.
Release the area through defined checks
Verify work completion, tool/part accountability, sound clean surfaces, required safe reassembly and equipment performance. Assess any potentially affected food.
Record who completed and checked the release, outstanding limitations and any procedure changes. Contractor guidance supports clear communication and records; check the food method after changes to equipment/layout.
Next steps
Use a work-and-release checklist with the contractor before work starts. Connect cleaning and HACCP review with equipment/layout changes.
