_________ and ________ must be completely immersed in disinfectant solution for the time specified on the product label.

• A. Implements and tools
• B. Sponges and brushes
• C. Hair and nails
• D. Doorknobs and handles

Answer: (A)

Disinfection depends on fully submerging reusable equipment in a disinfectant for the time specified on the product label. When tools and implements are completely immersed, every surface is exposed to the disinfectant long enough to kill the microorganisms that could be transferred between clients. This level of contact cannot be guaranteed by wiping or merely rinsing, which is why immersion is required for these items after cleaning. Implements and tools are the items designed to come into contact with clients and be reused across clients, so they must meet the label’s contact time to be considered disinfected. Other items—like sponges and brushes, which can be porous and may have different handling instructions—often require special consideration, and hair and nails refer to client tissues rather than tools, while doorknobs and handles are typically cleaned and disinfected surfaces rather than items meant to be immersed as part of tool sanitation.
