Question

technician a says that hands should be washed for at least 20 seconds in warm water with soap. technician b says that hand sanitizer is an acceptable replacement to hand washing. who is correct?

○ a. technician a

○ b. technician b

○ c. both technician a and technician b

○ d. neither technician a nor technician b

Explanation:

• Technician A: Handwashing with soap and warm water for ≥20 seconds is a standard, effective hygiene practice (removes germs, dirt).
• Technician B: Hand sanitizer is not a replacement for handwashing (e.g., when hands are visibly dirty, sanitizer is less effective). Thus, only Technician A is correct.

Answer:

a. Technician A
