Contamination control is a critical part of operating cleanrooms in the healthcare, pharmaceutical and biotech industries. 

To stay on top of contamination control and ensure you’re maintaining your environment to the necessary level of cleanliness for operation, a robust disinfection schedule is essential.  

This blog will go over key regulatory considerations and walk you through building a simple rotation schedule for disinfecting cleanrooms, step by step. 

Key principles from Annex 1 

Annex 1 of the EU cGMP sets out the requirements for manufacturing sterile medicinal products. 

The guidelines outline some key principles for disinfecting cleanrooms:

  • Regularly clean and disinfect cleanrooms to minimise microbial contamination
  • Select disinfectants based on efficacy against the spectrum of microorganisms that might be encountered
  • Rotate disinfectants periodical, taking care to include a Sporicidal product especially in Grade A and B areas
  • Validate cleaning and disinfection processes to ensure their effectiveness
  • Carry out routine monitoring to verify ongoing control

 

Developing your Contamination Control Strategy

Creating a disinfection schedule in line with Annex 1 guidance involves a few key steps.

1. Assess your cleanroom environment

Identify the specific requirements of your cleanroom, including the types of surfaces, equipment, storage capabilities, and the frequency of use. 

2. Select your cleaning agents and disinfectants 

Choose a range of disinfectants that are effective against a broad spectrum of microorganisms. Ensure they are compatible with the materials and surfaces in your cleanroom.

3. Plan your rotation 

Develop a rotation plan for the cleaning agents and disinfectants to inline with cGMP guidance.

4. Documentation and training 

Keep detailed records of the disinfection process and train personnel to follow the procedures correctly.

5. Regularly review and update

Periodically review and update the disinfection schedule based on monitoring results and any changes in cleanroom usage or contamination patterns.

 

Sample disinfection rotation schedule

A well-planned and executed disinfection schedule is vital for maintaining the required cleanliness of your cleanroom. By following the guidelines set out in Annex 1 of the EU cGMP and incorporating AGMA Ltd products into your rotation plan, you can ensure a high standard of cleanliness and prevent microbial contamination. Regular monitoring and validation of the disinfection process will help sustain the efficacy and compliance of your cleanroom environment.

Contamination control – the AGMA way
