Hygiene Challenges —
And How the OHI Solves Them
Four situations technical leaders in paint and coatings manufacturing face, and the OHI path built for each one.
Operational hygiene in paint and coatings manufacturing is not a peripheral concern. It sits at the intersection of product quality, process reliability, regulatory compliance, and worker safety. Yet in many facilities, hygiene strategies are built on habit, intuition, or scattered responses to problems as they arise. They lack structure, measurability, and foresight.
The Operational Hygiene Index is designed for facilities that are ready to move beyond reactive hygiene management. It provides a structured methodology to assess your current hygiene performance, understand the root causes of your challenges, and build a prioritized roadmap for sustainable improvement.
Different facilities face different hygiene challenges. Whether you are planning a new facility, redesigning an existing one, fighting a contamination crisis, or preparing for certification and audit readiness, the OHI offers a tailored path. This article walks through four common scenarios and shows exactly where the OHI helps and which phases fit your situation best.
Greenfield – New Facility Planning
The Situation
You are planning a new production facility from scratch. Equipment specifications, process flow diagrams, and production schedules are taking shape, but there is no facility yet to walk through. Hygiene often becomes an afterthought, grafted onto the design late in the process, or based on general best practice assumptions that may not fit your specific product portfolio or production environment.
The risk is high: once a facility is built with hygiene gaps baked in, retrofitting is expensive and disruptive. Contamination pathways designed into the layout cannot easily be removed. Cleaning systems that were not properly sized become operational bottlenecks.
Why the OHI Helps
Since there is no facility to visit yet, the OHI starts with a standard remote kick-off session that captures your planned production processes, equipment, and layout. Targeted questionnaires then dig into the systems and processes relevant to your design, from pump and pigging line planning to cleaning concepts, sharpening the picture while your design is still flexible and changes are still affordable.
Once the facility is built, an on-site audit validates the planning, helps implement the process landscape developed together, and delivers concrete recommendations before production starts.
Which OHI Format Works Best
Standard Kick-off, followed by the questionnaire phase. The on-site audit follows later, once there is a facility to walk through, either right before start-up or shortly after.
The Outcome
You avoid costly retrofits. Your new facility is designed for hygiene from day one, with realistic cleaning cycles, minimized contamination pathways, and an operations team equipped with procedures that actually fit the facility layout.
The Situation
You are working with an existing facility. Unlike a greenfield project, there is already a plant to walk through: existing equipment, existing habits, and, in many cases, hygiene gaps that have gone unnoticed for years.
Sometimes a retrofit is already being planned, and the priority is to shape it before the scope and budget are locked in. Other times nothing is planned at all, and the priority is simply to find out where the facility actually stands today, so you can decide what needs to change, and how urgently.
Why the OHI Helps
Because a facility already exists, Case 1 starts with an extended kick-off: we visit your site, analyzing existing processes, equipment, and hygiene challenges in real time. Targeted questionnaires deepen the understanding of system-specific issues, and together we develop a retrofit concept, along with concrete technical recommendations, that addresses your operational hygiene gaps before implementation begins.
If no retrofit is currently planned and you simply want an independent read on where your facility stands today, Case 2 takes a different path: a standard kick-off, followed by questionnaires and an on-site audit that establishes the current state and delivers a Process Landscape, a Roadmap, and concrete recommendations, whether or not a retrofit turns out to be the right next step.
Which OHI Format Works Best
Extended Kick-off if you are still shaping the retrofit concept, so gaps are caught before implementation. Standard Kick-off with a closing audit if the retrofit is already complete and you need validation.
The Outcome
You get clarity instead of guesswork, whichever situation you're in. A retrofit gets built around hygiene from the start, tailored to the products you actually plan to make, not just the ones you make today. Moving into preservative-free paints, for example, is one of the most common reasons a retrofit becomes necessary in the first place. And if nothing is planned yet, you know exactly where your facility stands today, and what needs to change, backed by a documented Process Landscape, a Roadmap, and concrete technical recommendations you can act on right away.
The Situation
You have a contamination problem. Microbial counts are elevated, you are seeing unexpected contamination in finished product, or you are failing customer audits on hygiene. Quick fixes have not resolved the issue, or it keeps resurfacing. The root cause is unclear: a cleaning protocol failure, a design flaw in the equipment, a raw material issue, or a combination nobody has systematically analyzed together.
Why the OHI Helps
The extended kick-off is deployed immediately. Our team visits your facility on-site to investigate the root causes across microbiology, process engineering, and facility-specific conditions. We deliver initial concrete recommendations and direct measures to contain and resolve the crisis, without waiting on a multi-week analysis process. If needed, targeted questionnaires follow afterward to deepen the analysis and support long-term corrective actions.
Which OHI Format Works Best
An Extended Kick-off. When contamination is active, there is no time for a multi-phase process before getting eyes on the problem. Once the immediate crisis is under control, the remaining phases follow: checking the rest of the facility for related risks, and defining what needs to change to keep the same problem from coming back. That follow-through is the actual outcome of the OHI, not just the fix.
The Outcome
You understand what is actually causing your contamination problem, with a prioritized set of first interventions that address root causes, not symptoms. Your team can act with confidence instead of guessing, and you start rebuilding customer trust. Where you continue through the remaining phases, you also find out whether the same risk exists elsewhere in the facility, and get a prioritized Roadmap for closing it for good, not just resolving this one incident.
Certification & Audit Readiness
Which Challenge Is Yours?
Whether you are planning a new facility, shaping a retrofit, assessing an existing facility's current hygiene status, facing a contamination crisis, or preparing for certification, the OHI methodology adapts to where you stand. Book a call to discuss which path fits your situation.
The Situation
A customer, a regulatory body, or an internal review has flagged hygiene as an area of concern, or you are preparing for a planned audit and want confidence going in. You need to demonstrate that your hygiene practices are systematic and defensible, not just checklist entries. Most hygiene documentation relies on subjective assessments, and you cannot always prove that your cleaning is effective or that your procedures are based on data rather than habit.
Why the OHI Helps
The OHI delivers the complete picture. A standard remote kick-off captures your current state, production landscape, and compliance requirements. Comprehensive questionnaires then capture every relevant detail of your systems and processes. An on-site audit provides deep investigation, delivers detailed findings, and results in a complete, audit-ready report, backed by an objective and reproducible methodology rather than a checklist.
Which OHI Format Works Best
Standard Kick-off, followed by the full questionnaire and audit phases. This is the complete OHI package, built specifically for certification and audit readiness.
The Outcome
You pass your customer or regulatory audit with confidence, backed by documented, data-driven evidence of your hygiene practices. You receive your OHI certification and a clear, documented roadmap for ongoing compliance.
