For any industry operating a cleanroom, adhering to a strict Contamination Control Strategy (CCS) is essential. Every element inside and outside the cleanroom presents a potential contamination risk, making control a continuous challenge.

Whether you’re manufacturing pharmaceuticals, conducting biological research or working on electrical component production, contamination of a cleanroom, such as harmful microbes in a healthcare setting, or dust in semi-conductor production, can have catastrophic results. Even minor protocol deviations can result in costly downtime, deep cleaning procedures, product loss, and reputational damage.

Protecting cleanroom integrity requires a proactive approach. In this article, we focus on four critical factors that influence cleanroom stability: Environment, Process, People, and Product.

Environment

The maintenance of your cleanroom environment and surrounding areas should follow strict protocols as the first step in negating any potential contamination risks.

An effective cleanroom cleaning process follows a “top-down” approach, starting at the ceiling and moving to the floor.

Key environmental best practices include:

  • Using specialised, non-shedding materials
  • Selecting cleanroom-approved cleaning agents
  • Preventing cross-contamination between zones
  • Cleaning from the cleanest to the least clean areas

When performed consistently and correctly, this structured approach significantly reduces contamination risk and helps avoid unplanned downtime.

Process

Cleanroom cleaning procedures follows a strict, two-stage process: decontamination (cleaning) and disinfection, using non-shedding materials, specialised chemicals, and techniques like AGMA’s 5-step wiping technique https://agma.co.uk/news/5-step-wiping-technique/

People: Controlling the primary source of contamination

By far the most common source of contamination in a cleanroom is the human personnel inside it. In fact, human beings account for over 80% of the contaminants found in these areas. Much of this contamination happens without any effort, as we typically shed about one billion skin cells every day.

To reduce people-related contamination:

  • Provide comprehensive cleanroom training
  • Enforce strict gowning procedures
  • Promote good hygiene practices
  • Conduct regular protocol refreshers
  • Monitor compliance consistently

Product

Every product used inside a cleanroom must align with your CCS. From wipes and mops to disinfectants and consumables, unsuitable materials can introduce fibres, residues, or chemical incompatibilities.

When selecting products, consider:

  • Compatibility with your cleanroom classification
  • Material shedding properties
  • Chemical efficacy and residue profile
  • Regulatory compliance requirements

Using cleanroom-approved, validated products reduces risk and supports operational continuity.

When your Environment, Process, People, and Product strategies work together, your cleanroom remains stable, compliant, and operational.
