infections like boils and abscesses?
A) Streptococcus
B) Staphylococcus aureus

7. When should barber tools be disinfected?
A) Once a day
B) After each client
C) Weekly
D) Monthly
Answer: B
Rationale: Tools must be disinfected after each client to prevent
cross-contamination and the spread of infectious agents.
