1Under the Irish Safety, Health and Welfare at Work Act 2005, which of the following is a primary legal duty of a salon employee?

A.To report any workplace hazards or defects in equipment immediately to the employer

B.To purchase their own personal protective equipment (PPE) for chemical applications

C.To set the retail prices of services to cover safety inspections

D.To conduct annual independent safety audits of the salon premises

Explanation: Under the Safety, Health and Welfare at Work Act 2005 in Ireland, employees are legally required to take reasonable care of their own safety and that of others, which includes reporting any hazards, defects, or unsafe equipment immediately to their employer. Employers, not employees, are responsible for providing PPE and arranging safety audits.

2What is the recommended operating protocol for an autoclave to guarantee complete sterilization of metal hairdressing tools?

A.121°C (250°F) at 15 psi for at least 15 minutes

B.100°C (212°F) at 10 psi for 5 minutes

C.80°C (176°F) at atmospheric pressure for 30 minutes

D.150°C (302°F) at 5 psi for 10 minutes

Explanation: An autoclave sterilizes metal tools using saturated steam under high pressure. The standard international protocol to kill all microorganisms and spores is exposing items to 121°C (250°F) under 15 pounds per square inch (psi) of pressure for a minimum of 15 minutes. Lower temperatures or pressures only disinfect and do not sterilize.

3A client presents with tiny, oval-shaped greyish-white cases cemented firmly to the hair shafts near the scalp, accompanied by intense itching. What is this condition, and what is the required salon action?

A.Pediculosis capitis (head lice); politely decline the service and advise treatment

B.Pityriasis capitis (dandruff); proceed with an intensive anti-dandruff treatment

C.Trichorrhexis nodosa; perform a deep conditioning treatment and proceed with cut

D.Tinea capitis (ringworm); apply a topical antiseptic and continue blow-drying

Explanation: The presence of nits (lice eggs) cemented to the hair shafts indicates Pediculosis capitis (head lice), which is highly contagious. To prevent cross-contamination in the salon, the stylist must politely decline the service, explain the condition privately, and recommend over-the-counter pediculicide treatment.

4During a consultation, you observe a circular patch of hair loss on the client's scalp with red, scaly skin and broken hair shafts that look like black dots. What is the most likely condition and appropriate response?

A.Tinea capitis (ringworm); refuse the service and recommend medical referral

B.Alopecia areata; proceed with styling using volumizing products to cover the patch

C.Psoriasis; perform an exfoliating shampoo and proceed with permanent coloring

D.Seborrheic dermatitis; apply high-heat styling to dry the patch and proceed

Explanation: Tinea capitis is a fungal infection of the scalp characterized by red, scaly, circular patches and stubby, broken hairs. Because it is highly contagious, the service must be refused, and the client should be advised to consult a general practitioner for oral antifungal treatment. Alopecia areata, by contrast, presents as smooth, non-scaly bald patches.

5What is the key scientific distinction between sterilization and disinfection in a salon environment?

A.Sterilization destroys all microbial life including bacterial spores, while disinfection only reduces the number of pathogens

B.Disinfection destroys all spores, whereas sterilization only washes away dirt and surface oils

C.Sterilization is used exclusively on towels, while disinfection is used on metal shears

D.Disinfection uses high pressure and steam, while sterilization uses only liquid chemicals

Explanation: Sterilization is the highest level of decontamination, destroying all forms of microbial life, including highly resistant bacterial spores. Disinfection is a lower level of decontamination that kills most pathogens on non-porous surfaces but is generally ineffective against bacterial spores.

6When performing an allergy alert (patch) test prior to a permanent hair coloring service, where should the colorant be applied and how long should it remain?

A.Behind the ear or in the crook of the elbow, left undisturbed for 48 hours

B.Directly on the crown of the scalp, rinsed off after 10 minutes

C.On the client's wrist, covered with plaster and washed off after 1 hour

D.On a single strand of hair at the nape, left for 24 hours before rinsing

Explanation: A patch test checks for hypersensitivity to dye ingredients (specifically paraphenylenediamine, or PPD). The unmixed colorant (or color mixed with developer) is applied behind the ear or inside the elbow and left for 48 hours. If any redness, itching, or swelling occurs, the service must not be performed.

7Which of the following is the most effective method for preventing occupational contact dermatitis among salon stylists?

A.Wearing appropriate protective gloves during all shampooing, mixing, and chemical application services

B.Applying barrier cream to the client's hairline before a haircutting service

C.Washing hands with extremely hot water and heavy-duty soap after every client

D.Avoiding the use of hair conditioners and styling oils in the salon entirely

Explanation: Contact dermatitis is a common occupational skin condition in hairdressing caused by prolonged exposure to water, shampoos, and chemicals. Wearing single-use, powder-free nitrile or vinyl gloves when washing hair and handling chemicals shields the skin barrier and prevents irritation and sensitization.

8What is the primary purpose of a Safety Data Sheet (SDS), formerly known as Material Safety Data Sheet (MSDS), in the salon?

A.To provide comprehensive safety, handling, and emergency information for chemical products used in the salon

B.To list the wholesale prices and ordering numbers of professional hair products

C.To act as a training manual for advanced cutting and blow-drying techniques

D.To record client allergy histories and chemical service formulations

Explanation: A Safety Data Sheet (SDS) is a legal document provided by manufacturers that details the chemical ingredients, physical hazards, safe handling instructions, storage guidelines, and first-aid measures for salon products like colors, developers, and perms. Stylists must have access to SDSs to handle accidental spills or exposure correctly.

9Why should a stylist prioritize open-ended questions during the initial client consultation?

A.To encourage the client to describe their hair habits, preferences, and expectations in detail

B.To limit the consultation time and ensure the client answers with a simple 'yes' or 'no'

C.To steer the client toward the most expensive chemical treatments available

D.To document formal legal consent before performing patch tests

Explanation: Open-ended questions (e.g., 'How do you style your hair at home?') require more than a single-word answer, encouraging the client to explain their routine, lifestyle, and hair goals. This provides the stylist with critical diagnostic context that closed questions ('Do you blow-dry your hair?') fail to extract.

10How is a hair porosity test performed during a client consultation, and what does it assess?

A.Slide fingers from hair ends up toward the scalp; it assesses how easily the hair absorbs moisture and chemicals based on cuticle status

B.Stretch a wet strand of hair between both hands; it assesses the strength of the inner cortex

C.Observe hair under a magnifying glass; it assesses the distribution of natural melanin pigments

D.Dampen a section of hair and comb it; it assesses the density of active hair follicles per square centimeter

Explanation: Porosity refers to the hair's ability to absorb moisture, which depends on how raised or flat the cuticle scales are. By sliding thumb and index fingers up a dry hair strand from ends to roots, a rough feel indicates raised cuticles (high porosity), while a smooth feel indicates flat, compact cuticles (low porosity).
