How should a barber sanitize their hands before providing a service?

Sanitizing hands effectively is crucial for barbers to prevent the spread of germs and ensure client safety. The correct method involves using soap and water or hand sanitizer. Washing hands with soap and water is the most effective way to remove dirt, bacteria, and viruses. It is recommended when hands are visibly dirty or after certain activities, like using the restroom or eating. Hand sanitizer, on the other hand, is a convenient alternative when soap and water are not readily available, provided it has at least 60% alcohol content to be effective.

The other options don't offer the same level of efficacy or practicality for this context. Alcohol wipes, while effective to some degree, may not cover all exposed surfaces thoroughly and are not a substitute for proper hand washing. Rinsing with water alone is insufficient, as it does not eliminate germs or dirt. Using antibacterial gel, while better than not sanitizing at all, lacks the thorough effectiveness that soap and water provide, especially if hands are heavily soiled. Thus, the most comprehensive and appropriate method is to use soap and water or a suitable hand sanitizer.
