In the field decontamination sequence for chemical exposure, why is removing clothing first?

• A. To remove the bulk of the contaminant and prevent secondary contamination.
• B. To demonstrate readiness.
• C. To reduce clothing costs.
• D. To hasten hospital transport.

Answer: (A)

When chemical exposure occurs, the first step in field decontamination is to remove clothing because it holds most of the contaminant and acts as a vehicle that can transfer the chemical to skin and to others. By taking off contaminated garments quickly, you remove the bulk of the contaminant from the body and reduce the chance of secondary contamination to the rescuer, others, and the surrounding environment. This sets up a safer, more effective decontamination process—skin can then be washed more thoroughly after the contaminated clothing is removed. The other options don’t address contaminant removal or the risk of spreading contamination, so they aren’t the reasons for starting with clothing removal.
