  1. 1Under New Jersey sanitation rules, what must occur before a reusable implement is disinfected?

    1. A. Clean it with detergent, then rinse it
    2. B. Rinse it, then place it in clean storage
    3. C. Disinfect it, then remove visible material
    4. D. Dry it, then clean it with detergent

    Answer: A

    Explanation: The rule requires “Cleaning all implements and tools thoroughly with a mild alkaline detergent” followed by rinsing with tap water, so cleaning and rinsing precede disinfection.

    Reference: Cosado (2009) — N.J.A.C. 13:28-3.2(a)1-2

  2. 2When must the cited EPA barber-tool disinfectant solution be replaced?

    1. A. Daily or whenever visibly dirty
    2. B. Every 3 days or whenever cloudy
    3. C. Weekly or whenever diluted
    4. D. Monthly or whenever the container is opened

    Answer: A

    Explanation: The barber/salon label directs, “Prepare a fresh solution daily or when visibly dirty.” The replacement trigger is either the daily interval or visible soil.

    Reference: US EPA, Pesticide Product Label, MAQUAT 128,02/13/2023 — Barber/salon instrument directions

  3. 3A patron shows signs of a communicable disease at the service area. What does New Jersey require?

    1. A. Perform only a dry service
    2. B. Provide the service with a double cape
    3. C. Decline the service while the condition is transmissible
    4. D. Disinfect only after completing the service

    Answer: C

    Explanation: The rule states, “No practitioner shall serve a patron whom the practitioner knows” has a disease reasonably expected to transmit during service. The service must be declined while that transmission risk exists.

    Reference: Special Adoption (2019) — N.J.A.C. 13:28-3.3(d)

  4. 4A barber notices a suspicious skin tag during consultation. What may the barber do under New Jersey rules?

    1. A. Remove it with a razor
    2. B. Burn it with an electrical device
    3. C. Avoid removal and refer the client appropriately
    4. D. Pierce it with a lancet

    Answer: C

    Explanation: New Jersey expressly bars licensees from removing skin tags; the service should not cross into a prohibited medical procedure.

    Reference: Cosado (2009) — N.J.A.C. 13:28-2.15

  5. 5What water service must a fixed New Jersey shop provide for shampooing and sanitation?

    1. A. Hot and cold potable water
    2. B. Cold nonpotable water only
    3. C. Bottled fragrance only
    4. D. No running water

    Answer: A

    Explanation: New Jersey shop standards require an adequate supply of hot and cold potable water.

    Reference: Cosado (2009) — N.J.A.C. 13:28-3.1

  6. 6Which disinfectant standard applies to reusable barbering implements in New Jersey?

    1. A. An EPA-registered product labeled bactericidal only
    2. B. An EPA-registered product labeled tuberculocidal
    3. C. A 70-percent isopropyl-alcohol chamber treatment
    4. D. A 100-PPM bleach circulation solution

    Answer: B

    Explanation: The controlling clause requires “a chemical disinfectant registered by the Environmental Protection Agency and labeled as being tuberculocidal.” The other treatments appear elsewhere in the sanitation system but do not replace this standard for reusable implements.

    Reference: Cosado (2009) — N.J.A.C. 13:28-3.2(a)3

  7. 7Before a shaving service, how should a barber chair headrest be prepared?

    1. A. Disinfected and covered
    2. B. Cleaned and covered
    3. C. Disinfected and left uncovered
    4. D. Cleaned and left uncovered

    Answer: A

    Explanation: The CIB asks how the headrest “MUST be” prepared and keys “disinfected and covered.” Both the disinfection step and the protective covering are required.

    Reference: Nj Barber Cib — Sample question 3

  8. 8Which finding is a contraindication to service under New Jersey's communicable-disease rule?

    1. A. A transmissible skin infection
    2. B. A preferred haircut photo
    3. C. Naturally curly hair
    4. D. A healed scar with intact skin

    Answer: A

    Explanation: A known or reasonably suspected communicable condition while transmissible requires the practitioner to withhold service.

    Reference: Special Adoption (2019) — N.J.A.C. 13:28-3.3

  9. 9What preparation does NIC require before beginning a straight-razor shave?

    1. A. Lather the beard and apply a steam towel
    2. B. Apply permanent hair color
    3. C. Leave the skin dry and unprotected
    4. D. Use a chemical relaxer

    Answer: A

    Explanation: The NIC shaving section evaluates lathering the beard and mustache area and applying a steam towel before shaving.

    Reference: Shaving with a straight razor — Shaving with a straight razor

  10. 10Which service falls within New Jersey's statutory definition of barbering?

    1. A. Cutting and arranging head hair
    2. B. Injecting cosmetic filler
    3. C. Removing a skin tag
    4. D. Performing laser resurfacing

    Answer: A

    Explanation: The statute includes shampooing, cutting, arranging, relaxing, or styling the hair of the head; the medical procedures are prohibited.

    Reference: P.L. 2025, c.171 (A4331 2R) — Section 1; definition of barbering
