Cleanrooms require strict environmental control to maintain sterility, prevent contamination, and ensure seamless operations.
Without a proactive preventative maintenance (PM) programme, various issues can arise, leading to costly downtime, contamination risks, and operational inefficiencies.
Below are ten common cleanroom problems that can be effectively mitigated through proper PM practices.
1. Door alignment issues and adjustments
Poorly aligned doors can compromise cleanroom integrity by allowing unfiltered air to enter and can also affect pressure differentials.
Even slight misalignments can create gaps or leaks that undermine the cleanroom's ability to maintain positive or negative pressure, leading to an increased risk of contamination.
Solution:
- Perform quarterly door checks and adjustments to ensure doors close properly and maintain pressure seals.
- Keep critical spare parts on hand, including door hinges, magnetic locks (maglocks), wave switches, and door indicator lights, to avoid costly delays in repairs.
- Address minor alignment issues early to prevent more serious structural problems that could require significant repairs or replacements.
- Utilise automatic door alignment systems to continuously monitor and adjust door positioning to prevent air leaks.
