What decontamination method is not recommended for removing vesicant from casualties?

The use of bleach as a decontamination method is not recommended for removing vesicants from casualties. Bleach can react with the chemical agents, potentially producing toxic fumes and further harming the affected individuals. Additionally, it may not effectively neutralize the vesicant, leading to prolonged exposure and injury. Instead, appropriate decontamination procedures typically involve washing with soap and water or using specific decontamination solutions designed for chemical agents.
