In healthcare settings, decontamination can involve cleaning and sterilizing medical equipment to eliminate pathogens. For individuals, it might mean washing hands thoroughly with soap and water or using hand sanitizers when those are unavailable. Hand sanitizers, typically containing alcohol, are effective at reducing bacteria, fungi, and some viruses, though they may not be effective against all types of microorganisms.4

On the battlefield, decontamination procedures are vital for removing chemical agents from personnel and equipment to prevent casualties. This can involve specialized cleaning solutions and protective gear.5
