What should you do if a client has an open wound on their hand?

Refusing service when a client has an open wound is essential for ensuring the safety and health of both the client and the technician. Open wounds can be a breeding ground for bacteria and can increase the risk of infection, particularly in a salon environment where tools and surfaces may not be perfectly sterile. By not proceeding with the service, the technician prevents potential complications that could arise from treating the wound or introducing pathogens into it.

Additionally, refusing service allows the technician to maintain professional standards and adhere to health regulations, which prioritize client safety. It also demonstrates a high level of care and responsibility, reinforcing trust between the client and the technician. This approach ensures that the technician is not exposed to any infectious agents, safeguarding their health as well.

The other options suggest actions that could compromise safety and do not align with best practices in a professional setting.
