What should a nail technician do to prevent cross-contamination?

Using disposable tools is crucial for preventing cross-contamination in a nail salon environment. Disposable tools eliminate the risk of transferring bacteria, fungi, or other pathogens from one client to another, which can occur when tools are reused. This practice helps maintain a sterile workspace and ensures the health and safety of clients.

When nail technicians use disposable tools, they can simply discard them after a single use, significantly reducing the chance of contamination. This is particularly important for items that come into direct contact with skin or nails, such as nail files, buffers, and applicators.

The other options do not effectively prevent cross-contamination. For example, sharing equipment with coworkers can lead to the exchange of infectious agents, while reusing files and buffers without proper cleaning can harbor pathogens. Rinsing tools in water does not adequately disinfect them and can still allow for the transmission of harmful microbes.
