How to Follow the Proper Cleanroom Gowning Sequence: The Step‑by‑Step Method That Protects Your Process

Consistent gowning procedures are one of the most effective ways to maintain contamination control inside a cleanroom. Because personnel are the number-one source of airborne particles, skin flakes, and fibers, following a precise gowning sequence helps ensure product integrity, safety, and compliance. This guide outlines the correct order for gowning and includes cleanroom-approved supplies available from MTE Solutions.

1. Remove Personal Items

Before entering the gowning area, remove jewelry, watches, earbuds, and any loose personal accessories. These items shed particles and cannot enter the controlled environment.

2. Put on Shoe Covers

Apply the first pair of shoe covers prior to crossing the line of demarcation. This prevents outside contaminants from entering the clean side of the gowning room.

3. Don Hair Net or Bouffant Cap

All hair must be fully enclosed. No strands, sideburns, or loose fibers should be visible.

4. Apply Beard Cover (If Needed)

For operators with facial hair, a beard cover must be worn so it overlaps securely under the chin.

5. Put on Inner Gloves

Inner gloves help prevent contamination while handling gown components. Choose accelerator‑free nitrile cleanroom gloves for low particle generation.

6. Put on the Cleanroom Coverall

Step into the coverall without letting it touch the floor. Zip or fasten it completely, ensuring sleeves overlap inner gloves.

7. Don Hood

Position the hood over the head and ensure complete coverage with no exposed hair. Tuck the hood inside the collar of the coverall for a secure seal.

8. Put on Boots or a Second Pair of Shoe Covers

If using cleanroom boots, secure them so they overlap the suit legs. If using dual shoe covers, apply the second pair after the coverall is donned.

9. Put on Cleanroom Goggles or Face Shield (If Required)

Goggles should form a clean, even seal. Avoid touching the inner surface.

10. Apply Outer Gloves

Wear a second pair of gloves over the sleeves of the coverall. Ensure the glove cuff creates a tight seal around the wrist.

11. Perform a Final Self-Check

• No exposed skin
• Gloves fully overlap sleeves
• No gaps around the hood or boots
• No tears, loose fibers, or improperly secured fasteners

12. Enter the Cleanroom Slowly

Use controlled movements when entering to reduce particle disturbance and maintain airflow integrity.
