Which action is performed on all new components before assembling the main during disinfection?

• A. Swab the interior of all new components with a one-percent hypochlorite solution
• B. Rinse with clean water only
• C. Apply paint to components
• D. Expose to sunlight for 24 hours

Answer: (A)

Disinfection before assembling system components depends on directly treating interior surfaces so any potential contaminants are eliminated before they come together. Swabbing the inside with a one-percent hypochlorite solution targets microbes that may be present on those surfaces, providing broad‑spectrum effectiveness and a practical, quick-action disinfection step. This helps prevent introducing bacteria, viruses, or spores into the main unit when assembly occurs.

Rinsing with clean water alone wouldn’t reliably kill microbes. Painting would introduce contaminants rather than disinfect, and exposing components to sunlight for 24 hours isn’t a dependable or sufficient disinfection method due to variable UV exposure and inadequate contact with all surfaces.
