SECTION 1: INFECTION CONTROL & SANITATION STANDARDS
1. What is the primary purpose of infection control in a cosmetology setting?
A. To make the salon look clean and presentable
B. To comply with state board regulations only
C. To prevent the spread of disease and protect clients and professionals
D. To reduce the cost of salon supplies
E. To improve the quality of hair services
C. To prevent the spread of disease and protect clients and professionals
EXPERT RATIONALE: Infection control is fundamentally designed to prevent the
transmission of pathogens between clients and professionals. This protects public health
and is the foundation of safe salon practice.
,2. Which of the following best defines "sanitation" in a cosmetology context?
A. The complete destruction of all microorganisms
B. The removal of all visible dirt and debris from tools
C. The significant reduction of pathogens on surfaces to safe levels
D. The sterilization of all implements before use
E. The chemical destruction of bacterial spores
C. The significant reduction of pathogens on surfaces to safe levels
EXPERT RATIONALE: Sanitation reduces the number of pathogens to a safe level but
does not eliminate all microorganisms. It is lower on the decontamination scale than
disinfection or sterilization.
3. What is the correct order of decontamination from lowest to highest level?
A. Sterilization, disinfection, sanitation
B. Sanitation, sterilization, disinfection
C. Disinfection, sanitation, sterilization
D. Sanitation, disinfection, sterilization
E. Sterilization, sanitation, disinfection
D. Sanitation, disinfection, sterilization
EXPERT RATIONALE: The three levels of decontamination from lowest to highest are
sanitation (reduces pathogens), disinfection (destroys most pathogens), and sterilization
(destroys all microbial life including spores).
4. Which type of disinfectant is most commonly used in California
cosmetology salons?
A. Quaternary ammonium compounds (quats)
,B. Bleach diluted 1:100
C. Isopropyl alcohol 40%
D. Formaldehyde solution

A. Quaternary ammonium compounds (quats)
EXPERT RATIONALE: Quats are the most widely used salon disinfectants because
they are effective against bacteria, viruses, and fungi, non-corrosive to metals, and safe
for most surfaces when used correctly.
5. How long must non-porous implements be immersed in an EPA-registered
disinfectant solution?
A. 5 minutes
B. 15 minutes
C. 30 minutes
D. As directed by the manufacturer's label
E. 1 hour
D. As directed by the manufacturer's label
EXPERT RATIONALE: The correct immersion time is always determined by the
manufacturer's label instructions, which are registered and approved by the EPA.
Following label directions ensures proper disinfection.
6. Which of the following is a porous implement that CANNOT be disinfected
and must be discarded after single use?
A. Metal nail file
B. Glass manicure bowl
C. Wooden cuticle pusher
, D. Stainless steel scissors
E. Plastic tail comb
C. Wooden cuticle pusher
EXPERT RATIONALE: Porous implements such as wooden tools, emery boards, and
buffers absorb fluids and cannot be effectively disinfected. They must be discarded after
single use or given to the client.
7. What does OSHA stand for?
A. Office of Safety and Health Administration
B. Occupational Safety and Health Administration
C. Organization of Sanitation and Hygiene Assistance
D. Occupational Sanitation and Hazard Authority
E. Office of Salon Health and Awareness
B. Occupational Safety and Health Administration
EXPERT RATIONALE: OSHA stands for Occupational Safety and Health
Administration, a federal agency that sets and enforces workplace safety standards,
including those relevant to salon environments.
8. What is an SDS (Safety Data Sheet) used for?
A. To record client service history
B. To document chemical hazards, handling, and emergency procedures for
products
C. To track inventory of salon products
D. To record employee work schedules
E. To list the ingredients in hair color formulas
