Cleanroom Coating Application Audit - Controlled Environment

Inspection template for auditing coating application activities in controlled environments, with emphasis on gowning, wipe-down practices, presaturated-wipe use, particle controls, and ISO-class cleanroom behaviors.

Inspection Details

• Area, process, and coating operation identified
  Record the cleanroom or controlled area inspected, the coating process in progress, and the work order or batch reference.
• ISO class or controlled-environment designation confirmed
  Select the applicable room classification or controlled-environment designation for the audit.
• Inspection date and time recorded
  Document when the audit was performed.

Personnel Gowning and Entry Control

• Gowning sequence followed before entry
  Verify that personnel followed the approved gowning sequence for the room classification and did not bypass any required step.
• Garments, gloves, mask, and hood are clean and intact
  Observe whether required PPE and cleanroom garments are free of visible tears, contamination, or improper fit.
• Hands and gloves sanitized before critical contact points
  Confirm hand hygiene and glove sanitization occurred before touching product-contact surfaces, tools, or coating materials.
• Personnel movement minimized to reduce particle generation
  Rate whether movement, talking, and unnecessary traffic were controlled to limit particle release during coating activities.

Surface Preparation and Wipe-Down Controls

• Approved wipe-down procedure available and followed
  Verify that the current SOP or work instruction for wipe-down was available at point of use and followed as written.
• Presaturated wipes used as required
  Confirm that presaturated wipes were used where required and that wipe material matched the approved specification for the controlled area.
• Wipe direction and technique prevent recontamination
  Observe whether wiping was performed in a controlled direction, with clean-to-dirty progression and no reuse of contaminated wipe surfaces.
• Surfaces dry, clean, and free of visible residue before coating
  Check that substrate and adjacent surfaces were visibly clean, dry, and free of lint, streaking, or residue before coating application began.

Coating Application and Material Handling

• Coating materials and tools protected from contamination
  Verify that coating containers, applicators, and tools were covered, staged, or handled in a way that prevented particulate contamination.
• Open containers minimized and controlled
  Confirm that coating containers were opened only as needed and were not left exposed longer than necessary.
• Material transfer into cleanroom followed contamination-control practice
  Observe whether materials entering the controlled area were wiped, staged, or transferred using approved contamination-control methods.
• Coating application performed without visible shedding or debris
  Check for visible fibers, flakes, dust, or other debris generated during application.

Particle Control and Environmental Practices

• Airflow paths and critical zones not obstructed
  Verify that personnel, carts, and materials did not block laminar flow, returns, or other designated airflow paths.
• Housekeeping maintained during coating operation
  Confirm that debris, used wipes, packaging, and excess materials were removed promptly and did not accumulate in the work area.
• Particle-generating activities controlled or segregated
  Verify that any particle-generating tasks were separated from coating application or otherwise controlled per site procedure.
• Observed particle control effectiveness
  Rate the overall effectiveness of contamination-control practices observed during the audit.
