,Domain 1: Infection Control, Sanitation, and Safety (Q1-Q20)
Q1: A Texas Class A barber is preparing to disinfect implements after a haircut. Which process
completely destroys all microbial life, including bacterial spores, on the implements?
A. Sanitizing with a quaternary ammonium compound
B. Cleaning with soap and hot water
C. Sterilization using an autoclave or chemical sterilant [CORRECT]
D. Disinfecting with EPA-registered hospital-grade disinfectant
Correct Answer: C
Rationale: Sterilization is the only process that destroys all microbial life, including resistant bacterial spores. Disinfection destroys
harmful organisms but does not eliminate spores, while sanitizing merely reduces the number of disease-causing germs on cleaned
surfaces. Per TDLR infection control standards, sterilization is required for implements that penetrate the skin, though standard
chemical disinfection suffices for non-penetrating tools in typical barbering operations.
Q2: During a haircut, a barber accidentally nicks a client's ear and draws blood. According to TDLR blood
exposure protocols, what must the barber do before removing gloves?
A. Immediately apply a styptic pencil and continue the service
B. Thoroughly clean and immerse all tools that contacted blood into hospital-grade EPA-registered
disinfectant [CORRECT]
C. Place all contaminated tools in a biohazard bag for disposal
D. Rinse the tools under warm running water and set them aside
Correct Answer: B
Rationale: TDLR blood exposure protocols require that before removing gloves, all tools and implements that contacted blood or
body fluid must be thoroughly cleaned and immersed in hospital-grade EPA-registered disinfectant. This is an exposure incident
defined as contact with broken skin, blood, or other potentially infectious materials during the performance of duties. Simply
rinsing tools or using a styptic pencil does not satisfy the regulatory requirement for proper blood exposure management.
Q3: A barber needs to prepare a bleach cleaning solution for disinfecting surfaces in the shop. If the active
disinfecting component is sodium hypochlorite, what is the correct proportion for a 10% bleach solution?
A. 10% bleach and 90% water [CORRECT]
B. 50% bleach and 50% water
C. 10% bleach and 10% water with 80% other chemicals
D. 1 part bleach to 10 parts water
Correct Answer: A
Rationale: A 10% bleach solution means 10% sodium hypochlorite (bleach) and 90% water. This is the standard proportion
recognized by TDLR for surface disinfection in barbering facilities. The solution should be mixed fresh every 24 hours or
whenever it has been contaminated to maintain efficacy, as bleach degrades over time and loses its disinfecting power.

, Q4: When should a bleach cleaning solution be remixed according to Texas barbering sanitation
standards?
A. Every 48 hours regardless of use
B. Every 24 hours or when the solution has been contaminated [CORRECT]
C. Only when the solution changes color
D. At the beginning of each work week
Correct Answer: B
Rationale: TDLR standards require that bleach cleaning solution be mixed every 24 hours or when the solution has been
contaminated, whichever occurs first. Sodium hypochlorite degrades over time, reducing its effectiveness as a disinfectant.
Waiting 48 hours or relying on color change alone is insufficient to guarantee the solution maintains the required concentration
for effective pathogen destruction.
Q5: A client arrives at a Texas barbershop with visible head lice. What is the correct course of action
according to TDLR regulations?
A. Proceed with the service while wearing additional PPE
B. Stop services immediately and refer the client to a physician for proper care [CORRECT]
C. Complete the service quickly and then disinfect all surfaces
D. Apply a lice treatment shampoo before cutting the hair
Correct Answer: B
Rationale: TDLR regulations require that if a client presents with head lice, the barber must stop services immediately and refer
the client to a physician for proper medical care. Head lice are highly contagious parasites, and attempting to provide services
could spread the infestation to other clients and the facility. This is a strict regulatory requirement, not a discretionary decision.
Q6: Which type of disinfectant is classified as EPA-registered and appropriate for use in a Texas
barbershop for disinfecting implements?
A. Phenolics and quaternary ammonium compounds (quats) [CORRECT]
B. Isopropyl alcohol at 50% concentration
C. Homemade vinegar solutions
D. Over-the-counter hand sanitizer gels
Correct Answer: A
Rationale: EPA-registered disinfectants approved for barbershop use include phenolics and quaternary ammonium compounds
(quats). These chemical agents are specifically formulated to destroy harmful organisms on implements and surfaces. Isopropyl
alcohol at 70% or higher may be used for some purposes, but 50% is insufficient, and homemade vinegar solutions and hand
sanitizers are not EPA-registered for implement disinfection in barbering facilities.
Q7: A barber is disinfecting implements and work surfaces after a client. What personal protective
equipment is required during this process?
A. Safety glasses and an apron
B. Gloves must always be worn when disinfecting implements and surfaces [CORRECT]
C. A face mask is sufficient for disinfection procedures
D. No PPE is needed if using quaternary ammonium compounds
