Decontamination method one involves

• A. Cleaning and then disinfecting with an EPA registered disinfectant
• B. Cleaning and then sterilizing
• C. Autoclaving
• D. Dry heat sterilization

Answer: (A)

Decontamination method one is a two-step approach: first clean to remove dirt and debris, then disinfect with an EPA-registered disinfectant to kill pathogens. Cleaning helps physically remove grime so the disinfectant can work effectively, and using an EPA-registered product ensures the disinfectant has been tested for effectiveness against common microbes on surfaces and tools used in esthetic settings.

Sterilization methods like autoclaving or dry heat sterilization are more intensive processes used for instruments that enter sterile body tissues; they require specialized equipment and are not the standard approach for routine decontamination in esthetics. Cleaning alone does not reliably kill microorganisms, so the combination of cleaning plus disinfecting is the appropriate first method.
