Donning and Doffing Chemical PPE: Step-by-Step for Maximum Safety

The best chemical suit is useless if it’s worn incorrectly or removed carelessly.
Most exposure incidents happen not during the task, but during donning and doffing.
This guide explains how to properly wear and remove chemical protective clothing to ensure full protection.

Why Donning and Doffing Matter

• Cross-contamination during removal is the most common failure point.
• Improper donning can leave gaps, unsealed seams, or exposed areas.
• Poor technique can compromise respirator sealing or glove-sleeve interface.

Preparing the Donning Area

• Designate a clean changing zone.
• Ensure proper lighting and ventilation.
• Lay out all PPE items in correct sequence.
• Use a mirror or assign a trained buddy.

Pre-Wear Suit Inspection

• Check for holes, tears, or seam failure.
• Test zippers and closures for smooth function.
• Confirm correct suit size and chemical rating.
• Verify gloves, boots, and hoods are undamaged.
• Check manufacturing date and expiration if applicable.

Donning Procedure

Step-by-Step Instructions

1. Wear moisture-wicking base layer.
2. Put on chemical-resistant inner gloves.
3. Step into suit legs carefully.
4. Pull on upper suit and zip fully.
5. Seal zipper flap if present.
6. Don respirator or facepiece securely.
7. Pull hood over head and respirator straps.
8. Don outer gloves over suit sleeves.
9. Tape interfaces at wrists, ankles, and hood if required.
10. Perform mobility check (reach, squat, turn).

Doffing Procedure

Step-by-Step Instructions

1. Decontaminate suit exterior if needed.
2. Remove outer gloves by peeling inside-out.
