What is a good example of cross-contamination?

Using an implement on a client after dropping it on the floor is a clear example of cross-contamination because it involves the transfer of pathogens from one surface (the floor) to an implement that will then come into contact with a client. Cross-contamination occurs when harmful bacteria or substances are unintentionally transferred from one surface or person to another. In this scenario, the floor is not a clean environment, and any pathogens present can easily contaminate the implement.

In contrast, using disinfected tools on a new client represents good hygiene practices, as those tools have been properly cleaned and sanitized, reducing the risk of contamination. Washing hands before a service is also a preventive measure that promotes cleanliness and hygiene; this is essential in minimizing the risk of transferring bacteria. Similarly, applying lotion with clean hands is a safe practice that does not involve the risk of using contaminated items. All these actions contribute to safe salon practices and reduce the chances of cross-contamination, unlike using an implement that has been dropped on the floor.
