• B. Firefighters should shower and change into clean clothing immediately.
• C. Only rinse exposed skin with water.
• D. Wear a respirator during decontamination.

Answer: (B)

Personal decontamination aims to remove hazardous residues from you as quickly as possible after an incident to prevent skin absorption, inhalation of remaining fumes, and spreading contamination to quarters and equipment. The best approach is to shower and change into clean clothing immediately. After exiting the incident scene, contaminated PPE is removed in a controlled decontamination area, and you thoroughly wash with soap and water, paying attention to skin, hair, and areas where residues can cling. Once clean, you dry off and change into fresh clothing, then proceed to a clean area in your quarters or station. This rapid, thorough decon minimizes ongoing exposure and protects you and those around you.

Returning to quarters in contaminated clothes would carry residues home and into living spaces. Simply rinsing only exposed skin misses contaminants that can cling to hair, skin folds, and clothing, leaving residues that can cause irritation or longer-term exposure. Wearing a respirator during decontamination isn’t part of the standard process for removing contaminants; the focus is on physically removing the residue, not continuing exposure protection in that moment.
