Which bleach concentration is appropriate for decontaminating clothing and equipment?

• A. 0.5%
• B. 2%
• C. 5%
• D. 20%

Answer: (C)

Concentration determines how effectively a disinfectant can inactivate pathogens on fabric and gear. For decontaminating clothing and equipment, a 5% sodium hypochlorite solution is used because it provides reliable disinfection across a broad range of organisms while remaining practical for typical gear when used correctly. We want enough strength to kill pathogens that may be present, but not so strong that it unnecessarily damages fabrics or creates hazardous conditions. Lower concentrations may not guarantee full disinfection, especially on heavily contaminated items, while much higher concentrations can harm materials and pose safety risks. Always follow the product label for contact time and rinse thoroughly after treatment.
