1. 1Before using a cord-connected thermal appliance at the start of a work shift, what electrical-safety check is required?

   1. A. Visually inspect it before that shift
   2. B. Inspect it only when it is relocated
   3. C. Test it only after a completed repair
   4. D. Inspect it only after damage is reported

   Answer: A

   Explanation: OSHA states that this equipment “shall be visually inspected before use on any shift.” Relocation is an inspection trigger for equipment otherwise exempt from shift checks, and testing after repair is a separate damaged-equipment rule.

   Reference: 1910.334 - Use of equipment. | Occupational Safety and Health Administration — paragraph (a)(2)(i), Visual inspection

2. 2Which layer is the innermost portion of a thick hair shaft?

   1. A. Cuticle
   2. B. Cortex
   3. C. Medulla
   4. D. Internal root sheath

   Answer: C

   Explanation: The NCBI hair histology text states, “The medulla is the innermost portion of the hair shaft.” The cuticle is outermost and the cortex lies between; the root sheath surrounds hair within the follicle.

3. 3A Pennsylvania barbershop operates two chairs. What total razor inventory is the minimum for those chairs?

   1. A. Two razors
   2. B. Three razors
   3. C. Four razors
   4. D. Six razors

   Answer: C

   Explanation: Pennsylvania requires “Two razors for each chair in operation.” Two operating chairs therefore require at least four razors.

   Reference: No Job Name — 49 Pa. Code § 3.54(16)

4. 4A Pennsylvania barber is asked to style a client's wig. How does the Barber License Law classify that service?

   1. A. Within the statutory practice of barbering
   2. B. Reserved exclusively to cosmetology practice
   3. C. Exempt only when performed by a wig retailer
   4. D. Outside licensed personal-service practice

   Answer: A

   Explanation: The statutory definition includes authority “to perform any service on a wig or hairpiece.” Styling the client's wig is therefore within barbering rather than reserved, retail-exempt, or outside licensed practice.

   Reference: 1931 Act 202.pdf — Barber License Law, section 2, definition of Barbering

5. 5Which personal protective equipment does FDA guidance explicitly recommend during hair-dye application?

   1. A. Protective gloves
   2. B. Splash goggles
   3. C. A chemical-resistant apron
   4. D. A filtering respirator

   Answer: A

   Explanation: FDA's safety guidance says, “Wear gloves when you apply the hair dye.” Goggles, aprons, and respirators are real PPE types, but gloves are the item this FDA application instruction expressly names.

6. 6A Pennsylvania barber proposes using an electrical appliance for a facial treatment. How is that method classified by the statutory barbering definition?

   1. A. An authorized barbering method
   2. B. A method limited to manual substitutes
   3. C. A method reserved to cosmetology shops
   4. D. A method allowed only under medical delegation

   Answer: A

   Explanation: The definition permits facial treatment “either by hand or by mechanical or electrical appliances.” The proposed electrical method is expressly included in barbering.

   Reference: 1931 Act 202.pdf — Barber License Law, section 2, definition of Barbering

7. 7A barber finds insulation damage on a blow-dryer's cord that could expose an employee to injury. Which disposition meets OSHA's rule?

   1. A. Quarantine it until a supervisor's visual reinspection
   2. B. Deenergize it until a routine maintenance interval
   3. C. Remove it until repair and testing render it safe
   4. D. Return it only after complete manufacturer replacement

   Answer: C

   Explanation: OSHA says a damaged item “shall be removed from service” until repairs and tests make it safe. The rule requires repair and safety testing, rather than mere reinspection or mandatory total replacement.

   Reference: 1910.334 - Use of equipment. | Occupational Safety and Health Administration — paragraph (a)(2)(ii), damaged equipment

8. 8Which structure at the base of the hair bulb supplies blood to the growing follicle?

   1. A. Dermal papilla
   2. B. Sebaceous gland
   3. C. Arrector pili muscle
   4. D. External root sheath

   Answer: A

   Explanation: The NCBI text identifies the dermal papilla as the structure that “provides vital blood supply to the growing hair follicle.” The other options are real follicular structures with different functions.

   Reference: Ncbi Histology Hair — Structure; hair bulb and dermal papilla

9. 9A barber is about to place a steam towel on a patron's face and neck before shaving. When should the towel's temperature be checked?

   1. A. After the towel has rested on the patron's face.
   2. B. Before the towel is applied to the patron's face.
   3. C. After lather has been worked into the patron's beard.
   4. D. After the towel has been removed from the patron's face.

   Answer: B

   Explanation: The Pennsylvania shave skills list states "Tests temperature of steam cloth towel" before "Applies a steam towel to the face and neck." Testing after contact cannot prevent excessive heat at first contact. Lathering follows this preparation step.

10. 10During a pre-haircut condition analysis, which visible fiber change is characteristic of progressive weathering damage?

    1. A. Cuticle lifting and chipping toward the tip
    2. B. New pigment production at the distal end
    3. C. Increased follicle depth along the shaft
    4. D. Formation of new medulla at the cut end

    Answer: A

    Explanation: The review describes “progressive damage to the fiber from root to tip” with cuticle scale lifting, chipping, and denudation. Those shaft signs indicate weathering damage relevant to service planning.
