How do you decontaminate an Andersen N6?

• A. Alcohol gauze
• B. Soap and water
• C. Bleach solution
• D. Rubbing alcohol

Answer: (A)

Decontaminating a device like the Andersen N6 relies on using a disinfectant that is effective on surfaces but gentle enough not to damage the equipment. An alcohol-based wipe or gauze is typically the best option. Isopropyl alcohol around 70% disinfects many common pathogens and dries quickly, so it cleans and disinfects without leaving moisture that could affect internal components, seals, or plastics. Using a pre-wetted alcohol gauze allows for controlled, uniform coverage of all exterior surfaces, which is safer and more convenient than soaking the device or using liquids directly.

Soap and water can remove debris, but they don’t guarantee disinfection unless paired with proper dwell time and drying, and moisture can pose risks to sensitive parts. Bleach is a strong disinfectant but can corrode metals and degrade plastics or adhesives and often requires thorough rinsing. Rubbing alcohol is effective, but a ready-to-use alcohol gauze provides consistent application and minimizes handling of liquids.

So, wiping the exterior with alcohol gauze accomplishes both disinfection and preservation of the device’s integrity.
