Cleaning and Process Validation in Cleanrooms: Is Paper Still the Only Alternative?
How can validation results be recorded in a cleanroom without compromising contamination control?
For many years, there was essentially one answer: paper.
However, with advances in technology and electronic records, an increasing number of companies are adopting new strategies for executing protocols directly in the field.
The question is no longer “Can technology be used?”
The right question is:
What is the most appropriate strategy to ensure contamination control, data integrity, and operational efficiency?
Paper is still widely used
In many companies, the process still follows this workflow:
- Printing the protocol
- Transferring the material into the classified area in accordance with internal procedures
- Manually recording the results
- Reviewing the documentation
- Archiving the records
This is a well-established process that teams are familiar with.
However, there is an important aspect that is often overlooked.
A common misconception is that only electronic equipment poses a risk in cleanroom environments.
In reality, any material introduced into the area should be assessed from a contamination control perspective.
This includes paper itself.
Conventional office paper is generally not used in classified areas.
Depending on the criticality of the environment, specific materials may be used, such as:
- Cleanroom paper
- Low-particle-shedding paper
- Materials supplied sterile or compatible with the company’s established transfer procedures.
The challenge is not the paper. Nor is it the tablet.
The discussion is often framed as a choice between paper and electronic devices.
In practice, this is not the most appropriate approach.
The objective should always be to reduce risk.
While paper requires controls related to particle generation and the introduction of materials into the area, electronic devices must be demonstrated to be compatible with the cleaning, disinfection, and operational requirements of that environment.
For this reason, the decision typically involves a risk-based assessment that considers, among other factors:
- Area classification (Grade A, B, C, or D);
- The Contamination Control Strategy (CCS);
- Ease of cleaning and disinfection;
- Compatibility with sanitizing agents;
- Ergonomics when used with gloves;
- Connectivity;
- Particle generation;
- Electronic records requirements, where applicable.
There is no universally “approved” device. There is an appropriate solution for each process.
How is the industry evolving?
More and more organizations are replacing some of their paper-based records with digital solutions.
Strategies currently adopted across the industry include:
- industrial tablets designed for regulated environments;
- dedicated mobile devices that remain permanently inside the cleanroom;
- commercial tablets with specific protective solutions, when supported by a risk assessment;
- mobile workstations (trolleys) equipped with industrial computers;
- direct integration with MES, EBR, LIMS, and validation platforms.
What benefits can be achieved?
When properly implemented, digital execution can provide several benefits:
- elimination of duplicate data entry;
- reduction in transcription errors;
- immediate attachment of evidence;
- complete traceability;
- greater alignment with Data Integrity principles;
- faster review by Quality Assurance;
- greater availability of information for audits and investigations.
How can organizations ensure that digital validation execution is also controlled, traceable, and compliant with Data Integrity requirements?
Simply replacing a printed protocol with an electronic version is not enough. Digitalization should encompass the entire validation lifecycle: protocol preparation and approval, test execution, recording of results, deviation management, attachment of evidence, traceability, and generation of final documentation.
This is precisely where specialized platforms can support the evolution of the validation process.
GO!FIVE® is a platform designed to support the management and digital execution of validation and qualification activities, including Process Validation and Cleaning Validation.
By using devices that are compatible with the strategy established for the classified area, protocols can be executed directly in GO!FIVE®, allowing records to be captured digitally as the activities are performed.
This makes it possible to centralize information, evidence, results, deviations, reviews, and approvals within a single environment, reducing manual steps and increasing traceability throughout the validation process.
Therefore, the transformation is not simply about replacing paper with a tablet.
It is about rethinking the validation process from end to end, combining contamination control, data integrity, traceability, and operational efficiency.
