An autoclave achieves sterilization primarily through:
Answer: Pressurized steam at high temperature
Autoclaves use pressurized saturated steam (typically 121°C/250°F at 15 psi) to destroy all microbial life including spores.
Before placing implements in an autoclave, they must first be:
Answer: Cleaned of all debris and dried
Implements must be thoroughly cleaned and dried before autoclaving; organic matter insulates organisms from steam penetration.
Which disinfection level is REQUIRED for items that contact intact skin but not mucous membranes in a barbershop?
Answer: Low- to intermediate-level disinfection
Items contacting only intact skin are classified as non-critical and require low- to intermediate-level disinfection per the Spaulding Classification system.
A barber notices the disinfectant jar solution has turned cloudy. The correct response is to:
Answer: Discard the solution, clean the jar, and prepare fresh solution
Cloudy solution indicates contamination or breakdown of the disinfectant, rendering it ineffective — it must be discarded and replaced immediately.
Which surface disinfection method is acceptable for barber chair headrests and armrests between clients?
Answer: Wiping with an EPA-registered disinfectant spray or wipe, allowing proper contact time
Non-immersible surfaces like chair headrests must be wiped with an EPA-registered disinfectant and allowed to remain wet for the manufacturer's specified contact time.
What information is a barber legally required to know about every disinfectant chemical used in their shop?
Answer: The Safety Data Sheet (SDS) contents for each product
OSHA's Hazard Communication Standard requires that Safety Data Sheets (SDS) be accessible for all hazardous chemicals in the workplace, including disinfectants.
Isopropyl alcohol at 70% concentration is used in barbershops primarily to:
Answer: Disinfect small surfaces and skin prior to service
70% isopropyl alcohol is an effective intermediate-level disinfectant for small surfaces and skin prep because water slows evaporation and increases contact time.
