Cleanroom Daily Audit

This template is written for ISO 7 and ISO 8 cleanrooms, where daily checks typically focus on pressure, particle counts, gowning, and controlled flow. It can also be adapted for adjacent controlled environments if your SOP defines the acceptance limits. If you operate a higher-grade room, you may need tighter thresholds and more frequent monitoring. The template is a starting point, not a substitute for your site-specific contamination control plan.

As the name suggests, this template is designed for daily use, usually at the start of the shift or before critical operations begin. Some sites also run a second audit after maintenance, cleaning, or a major personnel change. The right cadence depends on your risk assessment, product sensitivity, and environmental monitoring program. If conditions drift frequently, daily may be the minimum rather than the target.

A trained inspector, supervisor, quality associate, or cleanroom lead can complete it, provided they understand the room classification and the approved SOP. The person performing the audit should be authorized to recognize deficiencies and escalate non-conformances. In many facilities, the auditor is not the same person doing the work inside the room to preserve objectivity. If your process is regulated, document the role and training status of the inspector.

No single template satisfies ISO 14644 on its own, but this one supports routine operational checks that align with cleanroom control expectations. ISO 14644 programs usually also require defined monitoring plans, calibration control, and documented response to excursions. Use this audit alongside your environmental monitoring SOP, cleaning procedures, and change-control process. The template helps capture daily evidence, not replace the broader quality system.

The biggest mistake is recording only pass/fail without the actual measurement, such as pressure value, particle count, or humidity reading. Another common issue is skipping the sampling location or duration, which makes the particle result hard to defend later. Teams also miss gowning details like exposed skin, jewelry, or improper glove coverage. Finally, audits often fail when non-conformances are noted but no owner or corrective action is assigned.

Yes, and you should. Many sites add room-specific acceptance limits, additional gowning checks, material transfer rules, or product-specific contamination controls. You can also add fields for line clearance, cleaning verification, or equipment status if those are part of your daily release decision. Keep the core structure intact so the audit still follows the room walk-through in a logical order.

An ad-hoc check may catch obvious issues, but it usually leaves gaps in traceability, consistency, and follow-up. This template creates a repeatable record of the same critical conditions every day, which makes trends and recurring deficiencies easier to spot. It also helps different inspectors apply the same standard instead of relying on memory. For quality systems, the documented audit is far easier to defend than a verbal confirmation.

Treat it as a non-conformance and follow your escalation path immediately. That usually means pausing affected activity, notifying quality or facilities, and checking whether the excursion is tied to doors, HVAC, cleaning, or personnel movement. Record the measured value, the time, the location, and the corrective action taken. Do not close the audit until the issue is dispositioned according to your SOP.
