Which substance should not be applied to the exposed area during decontamination?

• A. Oil or cream
• B. Soap
• C. Water
• D. Ice packs

Answer: (A)

During decontamination, the goal is to remove the irritant from the skin as quickly as possible. Oil or cream should not be applied because the OC spray is carried in an oily mixture, and adding more oil will spread the irritant and create a film that resists washing. This makes removal harder and can extend symptoms. Water helps rinse the skin, and soap helps emulsify the oil so it can be washed away effectively. Ice packs aren’t a cleansing method; they may help with pain after cleaning but don’t remove the chemical, and using them during decontamination isn’t part of the proper procedure. So, oil or cream is not appropriate for decontamination.
