California State Board Barber Practice Exam

Question: 1 / 400

Which of the following should NOT be used as a disinfectant?

Isopropyl alcohol

Hydrogen peroxide

Household bleach (if not diluted properly)

Household bleach can be an effective disinfectant when used properly, but it must be diluted correctly to ensure its safety and effectiveness. If bleach is not diluted properly, it can lead to either insufficient disinfection or damage to surfaces and equipment. Unconcentrated or overly diluted bleach may not effectively kill pathogens, while overly concentrated bleach can be corrosive and hazardous.

In contrast, isopropyl alcohol and hydrogen peroxide are both widely accepted as effective disinfectants when used at the appropriate concentrations. EPA-registered hospital disinfectants have been tested for effectiveness and safety, making them suitable choices in a barbershop environment. Therefore, the caution about improper dilution makes the option concerning household bleach the choice that should not be used as a disinfectant in a professional setting.
