Question 1: What is the first step in the infection control process according to
California Board regulations?
A. Disinfection
B. Sterilization
C. Cleaning (removing visible debris)
D. Sanitizing
CORRECT ANSWER: C. Cleaning (removing visible debris)
Rationale: Cleaning is the mandatory first step in the infection control process. It
involves the physical removal of all visible debris, dirt, and oils from tools and surfaces.
Disinfection and sterilization cannot be effective unless items are properly cleaned first,
as organic matter can shield pathogens from chemical or heat processes .
Question 2: Which level of infection control destroys all microorganisms,
including bacterial spores?
A. Sanitation
B. Disinfection
C. Sterilization
D. Antisepsis
CORRECT ANSWER: C. Sterilization
Rationale: Sterilization is the highest level of infection control and destroys all
microorganisms, including bacterial spores. This is achieved through methods like
autoclaving (steam under pressure) or dry heat. Disinfection destroys most pathogens
but does not kill spores .
Question 3: What is the minimum contact time generally required for most
EPA-registered disinfectants to be effective on salon tools?
A. 1 minute
B. 5 minutes
C. 10 minutes
D. 30 minutes
CORRECT ANSWER: C. 10 minutes
,Rationale: EPA-registered disinfectants typically require a contact time of 10 minutes to
effectively destroy pathogens. It is critical to follow the manufacturer's specific
instructions for each product, as contact times can vary .
Question 4: Barbicide is classified as which type of disinfectant in a salon
setting?
A. Sterilant
B. Hospital-grade disinfectant
C. Antiseptic
D. Sanitizer
CORRECT ANSWER: B. Hospital-grade disinfectant
Rationale: Barbicide is a hospital-grade disinfectant effective against bacteria, fungi,
and viruses. It is not a sterilant and does not kill bacterial spores. It must be used
according to the manufacturer's directions for proper disinfection .
Question 5: What is the proper procedure for disinfecting metal implements
like shears and tweezers?
A. Wash with soap and water, then wipe with alcohol
B. Clean, completely immerse in EPA-registered disinfectant for required time, rinse, and
dry
C. Boil for 5 minutes
D. Wipe with a disinfectant wipe only
CORRECT ANSWER: B. Clean, completely immerse in EPA-registered
disinfectant for required time, rinse, and dry
Rationale: Metal implements must first be thoroughly cleaned to remove all debris, then
completely immersed in an EPA-registered disinfectant for the full contact time (usually
10 minutes), followed by rinsing and drying. This ensures all surfaces are properly
disinfected .
Question 6: How should clean, disinfected implements be stored?
A. In a closed, clean container
B. In a drawer with other tools
C. In an open container on the counter
D. In a damp towel
CORRECT ANSWER: A. In a closed, clean container
Rationale: After disinfection and drying, implements must be stored in a clean, closed
container or drawer to protect them from contamination until their next use. This
prevents recontamination from airborne pathogens or contact with unclean surfaces .
Question 7: Which of the following items is considered porous and must be
discarded after a single use?
,A. Metal shears
B. Glass mixing bowls
C. Emery boards and nail files
D. Stainless steel tweezers
CORRECT ANSWER: C. Emery boards and nail files
Rationale: Emery boards and nail files are porous and cannot be properly disinfected
because they can absorb blood and bodily fluids. They must be discarded after each
client to prevent cross-contamination .
Question 8: What does the term "universal precautions" refer to in a salon
setting?
A. Using the same products for all clients
B. Treating all blood and body fluids as if they are infectious
C. Applying the same haircut technique to all clients
D. Using universal tools for every service
CORRECT ANSWER: B. Treating all blood and body fluids as if they are
infectious
Rationale: Universal precautions are an approach to infection control where all human
blood and certain body fluids are treated as if they are known to be infectious for
bloodborne pathogens such as HIV and Hepatitis B. This protocol is mandated by OSHA
to protect salon professionals .
Question 9: What is the primary purpose of a patch test before a hair color
service?
A. To test the color result on a small strand
B. To determine if the client is allergic to the product
C. To check the hair's porosity
D. To practice the application technique
CORRECT ANSWER: B. To determine if the client is allergic to the product
Rationale: A patch test is performed to detect potential allergic reactions to hair color
products. It involves applying a small amount of the product behind the ear or on the
inner elbow and waiting 24-48 hours to check for a reaction. This is a crucial safety
step .
Question 10: What is the proper method for handling a sharps injury (e.g.,
needle stick)?
A. Ignore it if minor
B. Wash with soap and water, report to supervisor, seek medical attention
C. Squeeze the wound to promote bleeding and then apply a bandage
D. Apply a bandage and continue working
, CORRECT ANSWER: B. Wash with soap and water, report to supervisor, seek
medical attention
Rationale: A sharps injury requires immediate washing with soap and water, reporting
the incident to the supervisor, and seeking medical evaluation. This is important for
potential exposure to bloodborne pathogens and must be documented .
Question 11: What is the primary difference between disinfection and
sanitation?
A. They are the same thing
B. Sanitation reduces pathogens; disinfection destroys most
C. Disinfection is for surfaces; sanitation is for tools
D. Sanitation is more effective than disinfection
CORRECT ANSWER: B. Sanitation reduces pathogens; disinfection destroys
most
Rationale: Sanitation reduces the number of pathogens on a surface to a safe level,
while disinfection destroys most pathogenic microorganisms. Disinfection is a higher
and more rigorous level of infection control .
Question 12: According to California regulations, what is the minimum
temperature and time required for non-commercial laundering of towels?
A. 120°F for 15 minutes
B. 140°F for 20 minutes
C. 160°F for 25 minutes
D. Boiling water for 10 minutes
CORRECT ANSWER: C. 160°F for 25 minutes
Rationale: Towels, sheets, and linens must be laundered by a process that includes
immersion in water at least 160°F for not less than 25 minutes during the washing or
rinsing operation, unless a commercial laundry uses an approved cold-water chemical
process .
Question 13: What is the primary route of transmission for fungal infections
like tinea (ringworm) in a salon?
A. Airborne
B. Direct contact with contaminated surfaces or tools
C. Bloodborne
D. Foodborne
CORRECT ANSWER: B. Direct contact with contaminated surfaces or tools
Rationale: Fungal infections such as tinea (ringworm) are primarily transmitted through
direct contact with contaminated surfaces, tools, or infected skin. Proper disinfection of
tools and surfaces is essential to prevent transmission .
