SECTION 1: Sanitation, Disinfection & Safety (10 Questions)
Q1: According to Florida cosmetology regulations, which level of disinfection is required
for combs, brushes, and shears that come into contact with intact skin (non-porous
tools)?
● A. Level I (cleaning only)
● B. Level II (high-level disinfection)
● C. Level III (sterilization)
● D. Level II (intermediate-level disinfection)
Correct Answer: D
Rationale: Florida requires Level II disinfection (intermediate-level) for non-porous tools
contacting intact skin; this kills vegetative bacteria, fungi, and most viruses but not all
bacterial spores. Level III sterilization is required for tools entering sterile tissue.
Q2: A salon uses Barbicide for tool disinfection. What is the proper contact time for
hospital-level disinfection according to EPA guidelines?
● A. 2 minutes
● B. 5 minutes
● C. 10 minutes
● D. 30 minutes
Correct Answer: C
,Rationale: Barbicide and other EPA-registered hospital-level disinfectants require a full
10-minute contact time at proper dilution (typically 2 oz per 32 oz water) to achieve
bactericidal, virucidal, and fungicidal efficacy; shorter times do not ensure complete
pathogen destruction.
Q3: A cosmetologist is preparing a bleach solution for disinfecting surfaces after a
blood spill. What is the correct dilution ratio for household bleach (5.25-6% sodium
hypochlorite)?
● A. 1:5 (bleach to water)
● B. 1:9 (bleach to water)
● C. 1:15 (bleach to water)
● D. 1:20 (bleach to water)
Correct Answer: B
Rationale: OSHA bloodborne pathogens standard requires a 1:10 to 1:100 dilution
depending on application; for surface disinfection after blood spills, 1:9 (approximately
1:10) is the standard recommended dilution that achieves the necessary 5000-6000
ppm available chlorine for effective decontamination.
Q4: Which method of sanitation is MOST effective for destroying all microbial life,
including bacterial spores, on metal implements?
● A. Ultraviolet (UV) light sanitation
● B. Dry heat sterilization
● C. Autoclave (steam sterilization)
● D. Quaternary ammonium compound immersion
Correct Answer: C
Rationale: Autoclave steam sterilization (121°C at 15 psi for 15-30 minutes) is the only
method listed that achieves sterilization (Level III), destroying all microbial life including
, heat-resistant spores; UV light and dry heat are less reliable, and quaternary ammonium
compounds are low-level disinfectants only.
Q5: Under Florida's infection control rules for multi-client foot spa disinfection, what is
the minimum circulation time required with EPA-registered disinfectant between clients?
● A. 5 minutes
● B. 10 minutes
● C. 15 minutes
● D. 20 minutes
Correct Answer: B
Rationale: Florida administrative code (61G5-20) requires foot spas to be drained,
cleaned of visible debris, filled with EPA-registered disinfectant, and circulated for a
minimum of 10 minutes between clients to effectively eliminate biofilm and
Mycobacterium fortuitum risk.
Q6: A Material Safety Data Sheet (SDS) for a new hair color product must be kept on file
and accessible to employees. Under OSHA regulations, how long must the salon retain
the SDS?
● A. 1 year after discontinuation
● B. 3 years after discontinuation
● C. 5 years after discontinuation
● D. 30 years for certain hazardous substances
Correct Answer: D
Rationale: OSHA Hazard Communication Standard requires SDS retention for 30 years
for any chemical substance that has caused or may cause adverse health effects; all
other chemicals must be retained while in use and for a reasonable period after
discontinuation, but 30 years is the maximum requirement for hazardous substances.
