How to Prepare Your Food Manufacturing Facility for a BRC Audit: A Plant Manager’s Structural & Sanitation Checklist

If you run operations or quality at a food manufacturing plant, you already know BRCGS certification is rarely optional. Most UK retailers require it. Major US retailers are increasingly demanding it. And for the plants that sell into both markets, a Grade A or AA result is the difference between keeping major accounts and losing them at the next procurement review.

Here’s what most food safety teams underestimate: the vast majority of major and critical non-conformances in BRC audits do not come from documentation gaps. They come from what the auditor sees in the first twenty minutes of the physical plant walk-through. Flaking paint on an overhead beam. Dust accumulation on cable trays above an open production line. Unsealed concrete at the base of a wall. Rust bleeding through the coating on a structural support.

These are facility condition issues. They belong to plant engineering and maintenance, not to the QA department. And if they haven’t been addressed in the 30-60 days before the audit window, they’re almost guaranteed to show up in the report.

Why Structural Condition Drives Audit Outcomes

BRCGS Issue 9 expanded the weight given to fundamental clauses - the ones where a single non-conformance can pull a facility’s overall grade down by two full letters. Several of these fundamentals sit squarely in the physical condition of the building:

Clause 4.4 (Building Fabric). Walls, floors, ceilings, and structures must be in a condition that does not risk product safety or contamination. Flaking paint, delaminating coatings, and unsealed surfaces all fall here.

Clause 4.9 (Chemical & Physical Contamination Control). Foreign body prevention requires the physical plant itself to not be a source of contamination. Overhead structures are the most-cited offender.

Clause 4.11 (Housekeeping & Hygiene). Cleaning effectiveness is evaluated not just on documented frequency but on visible outcome. Accumulated dust at height is the single most common audit finding in dry-goods facilities.

The #1 Non-Conformance We See: Overhead Structures

If a BRC auditor is going to find a problem on your shop floor, it’s going to be above eye level. Roof trusses, joists, cable trays, conduit runs, sprinkler pipes, and HVAC ductwork accumulate dust, debris, and biological growth in quantities that are invisible from the floor but obvious when an auditor looks up with a flashlight.

This is exactly where specialized industrial cleaning earns its keep. Standard janitorial crews cannot safely reach or effectively clean a 35-foot-high truss system in an operating plant. High-reach scissor lifts, the right removal method for each area, and crews trained in working-at-height protocols are the minimum required. For dry-goods facilities with combustible dust exposure - flour, sugar, starch, powdered ingredients - NFPA 654 compliance adds another layer.

Paint and Coatings: Why “Flaking Paint” Is a Physical Hazard

Paint chips are a Class IV foreign body under most customer specifications. A single paint chip in a finished product traces back to a supplier audit finding, which traces back to a non-conformance, which traces back to the painted surface that shed it.

The fix is not a cosmetic repaint. It’s surface preparation to specification - typically SSPC-SP 6 or better for metal, sound-concrete prep for walls and floors - followed by a food-grade coating system rated for the exposure environment. Epoxy or polyurethane on high-traffic surfaces. Heat-resistant coatings on boiler rooms and utility areas. Hygienic wall coatings in wet-processing zones.

If your facility’s paint system is failing in three or more visible locations, you are at high risk of a major non-conformance under Clause 4.4.3. The 60 days before an audit is not when you want to discover this.

Combustible Dust: Where Food Safety and OSHA Converge

Dry-goods food plants have an exposure that straddles two regulatory worlds. BRC wants the dust gone because it’s a contamination risk. OSHA - under NFPA 654 and 664 - wants the dust gone because it’s an explosion risk. A single cleaning pass, done to the right standard, satisfies both.

The right standard means removing accumulated dust from every horizontal surface at height - not wiping down what’s visible from a ladder. A removal method matched to the area, HEPA-filtered industrial vacuum where the area calls for it, extended-reach tooling, and crews trained to work around live production are what the job takes. Any plant that produces or handles flour, sugar, powdered dairy, starch, or cocoa should be cleaning overhead structures on a documented quarterly cycle, with a pre-audit deep clean layered on top.

What an Audit-Ready Maintenance Cycle Looks Like

Facilities that consistently achieve Grade A results share a common pattern: they don’t treat the BRC audit as an event. They treat it as the outcome of a sustained facility condition program. The cycle most commonly works on a 90-day rhythm:

Quarterly overhead cleaning of every production and ingredient storage area. Documented scope, documented outcome, documented dust collection disposal.

Annual coating system inspection with a prioritized remediation list - which surfaces to address this year, which can wait, which need immediate attention.

Pre-audit deep clean 30-45 days before the known audit window, covering any areas not on the standard cycle: storage mezzanines, utility rooms, maintenance bays.

Post-audit remediation plan built into the following quarter’s work, so any findings from the last audit are provably closed before the next one.

Plants that run this cycle stop scrambling the week before audits. They also typically see their BRC grades stabilize or improve year over year - which is exactly what retailers want to see at supplier reviews.

How Kelly Industrial Services Supports BRC Preparation

Kelly has spent four decades doing the facility-condition work that BRC audits evaluate. We work with food manufacturers, corrugated packaging plants, and paper processors across the United States - including clients like International Paper and Georgia-Pacific - on the cleaning and coating programs that keep plants audit-ready.

Every technician on a Kelly project is a full-time Kelly employee. No subcontractors, no labor brokered to local third parties. That matters for BRC preparation because the auditor will ask about the competency and training of anyone performing cleaning inside your facility, and the documentation has to hold up.

Common Questions from Facility Managers

How far in advance should we start BRC audit preparation? For the facility-condition portion, 90 days is the working minimum. Coating remediation and overhead cleaning both require plant access that needs to be scheduled around production.

Do you work during production hours? Yes - most of our BRC-related work is done around live operations using containment, zoning, and shift-timed crews. Full plant shutdowns are rarely necessary.

What documentation do you provide for the auditor? Scope of work, cleaning records, technician training certifications, safety data sheets for all chemicals and coatings used, and photographic before-and-after records for any remediation work.
