What is the proper PPE decontamination sequence after exposure to hazardous materials?

• A. Decontaminate skin and eyes before doffing contaminated gear.
• B. Doffing contaminated gear outside, decontaminate skin and eyes, bag and isolate contaminated items, and medically evaluate if exposure occurred.
• C. Skip decon and continue working.
• D. Wash hands and return to duty.

Answer: (B)

The aim is to minimize self-contamination and the spread of hazardous material by sequencing decontamination and doffing carefully. Start by cleaning skin and eyes to remove contaminants from the body before touching or removing any gear, reducing the chance that material will be smeared onto clean areas or onto the gear you handle. Doffing contaminated gear outside the exposed zone keeps contaminants out of clean areas and minimizes the risk of bringing hazardous material into the rest of the environment. After gear is removed, decontaminate skin and eyes again because some material can transfer to skin during the removal process, so a second wash helps ensure you’re no longer contaminated. Bag and isolate the contaminated items so they can’t spread the hazard to others or to clean surfaces while you’re finishing up. Finally, seek medical evaluation if exposure occurred to assess the extent of exposure, monitor for symptoms, and determine any needed treatment. This sequence combines effective removal of contaminants with containment and medical follow-up, which is essential for responder safety.
