What is the purpose of surface barriers on work surfaces between clients?

• A. To prevent cross-contamination by creating a clean, disposable or easily cleanable layer changed between clients.
• B. To keep ink from drying.
• C. To decorate the workspace.
• D. To increase surface temperature.

Answer: (A)

Surface barriers create a protective boundary on the work surface, helping to prevent cross-contamination between clients. They provide a clean, disposable or easily cleanable layer that is replaced after each client, so any blood, saliva, or other fluids don’t transfer to the next person. This makes cleaning more efficient and supports infection control by reducing the chance of pathogens moving from one client to another. To be effective, the barrier should fully cover the working area, remain intact, and be changed if damaged or soiled. The other options don’t address safety or infection control: keeping ink from drying isn’t the purpose, decorating isn’t a safety function, and changing surface temperature isn’t affected by barriers.
