SECTION 1: SANITATION, STERILIZATION & INFECTION CONTROL



QUESTION 1: What is the highest level of decontamination used in cosmetology?

A. Sanitation B. Disinfection C. Antisepsis D. Sterilization E. Fumigation

CORRECT ANSWER: D – Sterilization RATIONALE: Sterilization destroys ALL
forms of microbial life including bacterial spores. It is the highest level of
decontamination, surpassing both sanitation and disinfection.



QUESTION 2: Which of the following best describes sanitation in a salon setting?

A. Killing all microbial life on surfaces B. Destroying 100% of pathogens including
spores C. Reducing the number of pathogens to a safe level D. Eliminating
viruses from tools E. Sterilizing implements with heat

CORRECT ANSWER: C – Reducing the number of pathogens to a safe level
RATIONALE: Sanitation lowers the number of pathogens to a safe, non-harmful
level but does not eliminate all microorganisms. It is the most basic level of
decontamination.



QUESTION 3: EPA-registered disinfectants used in salons must be labeled as:

A. Antifungal and antiseptic B. Food-grade and non-toxic C. Antibacterial only D.
Hospital-grade sterilizers E. Bactericidal, virucidal, and fungicidal

CORRECT ANSWER: E – Bactericidal, virucidal, and fungicidal
RATIONALE: Salon disinfectants must be EPA-registered and effective against
bacteria, viruses, and fungi to meet professional safety standards.

,QUESTION 4: What type of bacteria forms a protective shell to survive harsh
conditions?

A. Cocci B. Bacilli C. Spirilla D. Spore-forming bacteria E. Diplococci

CORRECT ANSWER: D – Spore-forming bacteria RATIONALE: Spore-
forming bacteria produce endospores that protect them from heat, chemicals, and
dryness. Only sterilization can destroy these spores.



QUESTION 5: Which of the following is a one-celled organism that can be beneficial or
harmful?

A. Virus B. Fungus C. Parasite D. Prion E. Bacteria

CORRECT ANSWER: E – Bacteria RATIONALE: Bacteria are single-celled
microorganisms. Some are beneficial (like those in the digestive system) while others
are pathogenic and cause disease.


QUESTION 6: The process of making tools safe for use by removing ALL
microorganisms including spores is called:

A. Disinfection B. Sanitation C. Antisepsis D. Decontamination E. Sterilization

CORRECT ANSWER: E – Sterilization RATIONALE: Sterilization is the
complete destruction of all microbial life. It is the highest standard and is required for
surgical or invasive tools.



QUESTION 7: What shape are cocci bacteria?

A. Rod-shaped B. Spiral-shaped C. Comma-shaped D. Round or spherical E.
Rectangular

CORRECT ANSWER: D – Round or spherical RATIONALE: Cocci are round-
shaped bacteria. They can appear alone (monococcus), in pairs (diplococci), in chains
(streptococci), or in clusters (staphylococci).

,QUESTION 8: Which of these salon implements requires sterilization rather than just
disinfection?

A. Combs B. Brushes C. Towels D. Cape E. Implements that penetrate the skin

CORRECT ANSWER: E – Implements that penetrate the skin RATIONALE:
Any implement that breaks the skin must be sterilized to prevent bloodborne pathogen
transmission. Non-invasive tools can be disinfected.



QUESTION 9: What does OSHA stand for?

A. Office of Safe Health Administration B. Operational Safety and Hygiene Authority C.
Occupational Safety and Health Administration D. Organization for Sanitary
Health Awareness E. Official Salon Health Authority

CORRECT ANSWER: C – Occupational Safety and Health Administration
RATIONALE: OSHA is a U.S. government agency that sets and enforces safety
standards in the workplace, including salons and cosmetology schools.



QUESTION 10: What is the proper way to store used implements before disinfection?

A. In a dry container B. In clean water C. On the work station D. In a closed container
labeled "contaminated" E. In the client's sight

CORRECT ANSWER: D – In a closed container labeled "contaminated"
RATIONALE: Contaminated tools must be placed in a clearly labeled closed container
to prevent cross-contamination until they can be properly cleaned and disinfected.


QUESTION 11: Quaternary ammonium compounds (quats) are commonly used in
salons as:

A. Sterilizing agents B. Food-safe cleaners C. Antiseptics for skin D. Disinfectants for
non-porous tools E. Wound cleansers

CORRECT ANSWER: D – Disinfectants for non-porous tools RATIONALE:
Quats are EPA-registered disinfectants effective on non-porous salon implements. They
are widely used because they are safe, effective, and relatively non-toxic.


QUESTION 12: Which of the following is NOT a bloodborne pathogen?

, A. HIV B. Hepatitis B C. Hepatitis C D. Streptococcus E. Hepatitis D

CORRECT ANSWER: D – Streptococcus RATIONALE: Streptococcus is a
bacterial infection spread via respiratory droplets, not blood. HIV and Hepatitis B, C, and
D are all bloodborne pathogens.



QUESTION 13: Universal precautions in a salon require treating:

A. Only visibly infected clients with extra care B. Only clients who disclose illness C.
Tools, not people D. The salon environment but not clients E. Every client as
potentially infectious

CORRECT ANSWER: E – Every client as potentially infectious RATIONALE:
Universal precautions require treating all blood and body fluids as potentially infectious
regardless of the client's known health status.



QUESTION 14: Phenolic disinfectants are known for being:

A. Gentle and safe for skin B. Ineffective against fungi C. Only useful for floors D. Very
powerful but potentially damaging to plastic E. Approved for direct skin
application

CORRECT ANSWER: D – Very powerful but potentially damaging to plastic
RATIONALE: Phenols are highly effective disinfectants but can be harsh on certain
materials like plastic and rubber and should not be used on the skin.



QUESTION 15: How long should implements typically soak in a disinfectant solution?

A. 1 minute B. 3 minutes C. 5 minutes D. 10 minutes E. 30 minutes

CORRECT ANSWER: D – 10 minutes RATIONALE: Most EPA-registered
salon disinfectants require a 10-minute soak time to effectively kill pathogens on
implements, though always follow manufacturer guidelines.


QUESTION 16: Which of the following microorganisms is the SMALLEST?

A. Bacteria B. Fungi C. Protozoa D. Parasites E. Viruses
