Show answer & explanation

Correct answer: C. Washing hands thoroughly with soap and water.

Handwashing is the single most effective way to prevent the spread of infections and is a fundamental practice in barbering sanitation. While other actions are good, handwashing directly removes pathogens from the barber's skin.

Why the other options are wrong

  • A. Spraying tools with hairspray is cosmetic and offers no sanitizing or disinfecting benefits.
  • B. Wiping with a dry cloth only removes visible debris and does not kill pathogens.
  • D. Arranging tools neatly is good for organization but does not prevent pathogen spread.

Handwashing

The act of cleaning hands with soap and water to remove microorganisms, dirt, and chemicals.

  • Essential for infection control in barbering.
  • Should be performed before and after each client.
  • Reduces the spread of pathogens significantly.

Memory trick: Clean hands keep clients healthy.
