I have extensive experience working with ISO Class 5 and Class 1 clean rooms. My previous role involved ensuring compliance with ISO 14644 standards, including regular monitoring of particle counts, temperature, and humidity. I also conducted training sessions for new employees on proper gowning procedures and contamination control measures.

In the event of a contamination incident, my first step is to isolate the affected area to prevent further spread. I then follow the established contamination control protocol, which includes identifying the source, cleaning the area, and retesting to ensure the environment meets the required standards. I also document the incident and any actions taken for future reference.

I implement a combination of preventive and corrective measures to maintain cleanliness. This includes regular scheduled cleanings, strict adherence to gowning procedures, and continuous monitoring of environmental parameters. I also conduct regular audits and provide feedback to the team to ensure everyone is aligned with the cleanliness standards.

I follow a rigorous sanitization protocol for all equipment and tools. This involves using approved cleaning agents, ensuring thorough drying to prevent microbial growth, and verifying the cleanliness through visual inspections and particle count tests. I also maintain a log of all sanitization activities to track compliance and identify any recurring issues.

In one instance, we experienced a sudden spike in particle counts despite following all standard procedures. After investigating, I discovered that a new batch of cleaning supplies was not up to the required standards. I immediately replaced the supplies, retrained the team on proper cleaning techniques, and implemented additional checks on incoming materials to prevent future occurrences.
