What is the standard ship oxidizer used in chemical decontamination?

• A. Hydrogen Peroxide (H2O2)
• B. Calcium Hypochlorite (HTH)
• C. Sodium Hypochlorite
• D. Ammonium Persulfate

Answer: (B)

Oxidizers in chemical decontamination are used to break down and neutralize contaminants by oxidation. Calcium hypochlorite is the standard ship oxidizer because it is a stable solid that can be stored in bulk with a long shelf life and is easy to handle on board. When dissolved in water, it releases chlorine to form hypochlorous acid, which actively oxidizes and neutralizes many chemical agents. This solid form is practical for shipboard use, storage, and repeated decon cycles. Hydrogen peroxide, while effective, is less stable on ships and can pose material compatibility issues. Sodium hypochlorite is a liquid that can degrade over time and complicate storage, especially on long deployments. Ammonium persulfate is not the typical oxidizer used for naval chemical decontamination.
