Which practice helps prevent cross-contamination when returning tools to storage between clients?

• A. Cleaning and sanitizing tools after each use
• B. Leaving tools on the treatment table
• C. Reusing dirty tools
• D. Sharing tools with coworkers

Answer: (A)

The main idea is preventing cross-contamination by cleaning and sanitizing tools after each client before putting them away. Cleaning removes residue, which allows sanitizing to work effectively, and sanitizing lowers the microbial count to a safe level. Storing tools after they’ve been cleaned and sanitized in a clean container or designated storage keeps them ready for the next client and prevents transfer of germs. Leaving dirty tools out on the treatment table, reusing dirty tools, or sharing tools with coworkers all increase the risk of spreading bacteria or viruses between clients. So, cleaning and sanitizing between uses is the best practice for keeping tools safe when returning them to storage.
