Question 1Occupational Health and Safety

Under WHMIS 2015, which pictogram indicates a product that can cause serious health effects such as cancer or respiratory sensitization?

  1. Corrosion
  2. Exclamation mark
  3. Flame
  4. Health hazard Correct answer.

Explanation

The health hazard pictogram shows a silhouette of a torso with a starburst and identifies products with serious health risks such as carcinogenicity, respiratory sensitization, or organ toxicity. The flame pictogram indicates flammability, corrosion indicates skin or metal damage, and the exclamation mark indicates less severe irritation or toxicity.

Question 2Occupational Health and Safety

How many standardized sections are required in a WHMIS 2015 Safety Data Sheet (SDS)?

  1. 12
  2. 24
  3. 16 Correct answer.
  4. 8

Explanation

WHMIS 2015 aligns with the Globally Harmonized System, which requires a 16-section SDS. The sections cover identification, hazards, composition, first-aid measures, firefighting, accidental release, handling and storage, exposure controls, and other information.

Question 3Occupational Health and Safety

What is the minimum recommended duration for washing hands with soap and water in a salon?

  1. 5 seconds
  2. 60 seconds
  3. 10 seconds
  4. 20 seconds Correct answer.

Explanation

Hands should be washed with soap and water for at least 20 seconds, using friction on all surfaces including between the fingers and under the nails. This contact time helps remove transient microorganisms and soil.

Question 4Occupational Health and Safety

Which task requires wearing disposable gloves?

  1. Answering the telephone
  2. Applying hair colour Correct answer.
  3. Sweeping hair from the floor
  4. Folding clean towels

Explanation

Disposable gloves create a barrier when handling hair colour, developer, bleach, and other chemicals that can irritate or sensitize the skin. Routine tasks that do not involve body fluids or chemicals generally do not require gloves.

Question 5Occupational Health and Safety

What does disinfection do to microorganisms on salon implements?

  1. Removes visible soil and organic matter from surfaces
  2. Prevents microorganisms from multiplying without killing them
  3. Kills all microorganisms including bacterial endospores
  4. Destroys most harmful microorganisms, not always spores Correct answer.

Explanation

Disinfection destroys or inactivates most harmful microorganisms on surfaces but may not eliminate bacterial spores. Cleaning must occur first because organic matter can reduce the effectiveness of the disinfectant.

Question 6Occupational Health and Safety

What is the first step when cleaning a blood spill on a non-porous salon floor?

  1. Pour disinfectant onto the spill
  2. Sweep the spill with a broom
  3. Put on disposable gloves and PPE Correct answer.
  4. Wipe up the spill with paper towels

Explanation

Personal protective equipment must be worn before contact with blood or other potentially infectious material. After PPE is on, the spill can be absorbed, cleaned with detergent, disinfected, and the waste disposed of according to workplace procedures.

Question 7Occupational Health and Safety

For immersion disinfection of non-porous implements with an intermediate-level disinfectant, what contact time is typical?

  1. 2 minutes
  2. 10 minutes Correct answer.
  3. 60 minutes
  4. 30 seconds

Explanation

The manufacturer's label is the authority, and many intermediate-level disinfectants used in salons require about 10 minutes of full immersion. Implements must be cleaned first and completely submerged for the labelled contact time.

Question 8Occupational Health and Safety

Why is a patch test performed before applying oxidative hair colour?

  1. To confirm the developer strength
  2. To detect a possible allergy Correct answer.
  3. To shorten the processing time
  4. To predict the final shade result

Explanation

A patch test helps identify a client who may be sensitized or allergic to an ingredient in the colour product before a full application. Manufacturer directions specify the timing and method, and a positive reaction means the service should not proceed.

Question 9Occupational Health and Safety

Why should chemical mixing be done in a well-ventilated area?

  1. To reduce inhaled vapours and fumes Correct answer.
  2. To speed up the chemical reaction
  3. To improve the colour deposit
  4. To keep the product from drying out

Explanation

Mixing can release vapours and fumes that irritate the respiratory tract or cause sensitization. Local exhaust or general ventilation helps keep airborne exposure as low as reasonably achievable.

Question 10Occupational Health and Safety

How should flammable salon chemicals be stored?

  1. On a sunny windowsill for easy access
  2. In a cool, dry area away from ignition Correct answer.
  3. Near a heat source to keep them active
  4. In unlabelled spray bottles for quick use

Explanation

Flammable products should be kept in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Containers must remain labelled and closed when not in use.

Question 11Occupational Health and Safety

What is the main purpose of an anti-fatigue mat at a styling station?

  1. To raise the client's chair to a comfortable height
  2. To protect the floor from chemical spills
  3. To reduce strain from prolonged standing Correct answer.
  4. To prevent slipping on wet hair clippings

Explanation

Anti-fatigue mats cushion the feet and encourage small postural changes, which can reduce strain on the feet, legs, and lower back during long periods of standing. They are not a substitute for proper footwear, posture, and breaks.

Question 12Occupational Health and Safety

What is the safest way to lift a heavy box of supplies?

  1. Twist the torso while lifting
  2. Lift with straight legs and arms extended
  3. Bend at the waist and reach forward
  4. Bend the knees and keep the load close Correct answer.

Explanation

Bending the knees and keeping the load close to the body reduces the strain on the lower back. The lift should be smooth, without twisting, and assistance or a cart should be used if the load is too heavy.

Question 13Occupational Health and Safety

Which work practice helps prevent carpal tunnel syndrome in a hairstylist?

  1. Keeping wrists neutral and taking breaks Correct answer.
  2. Resting wrists on hard, sharp edges
  3. Using tools with handles that are too small
  4. Gripping scissors tightly for long periods

Explanation

Neutral wrist posture and regular breaks reduce prolonged compression and repetitive strain on the wrist. Tool handles should fit the hand comfortably, and awkward postures should be avoided.

Question 14Occupational Health and Safety

Which class of fire extinguisher is appropriate for an electrical fire involving a hair dryer?

  1. Class K
  2. Class A
  3. Class B
  4. Class C Correct answer.

Explanation

Class C extinguishers are intended for fires involving energized electrical equipment and use non-conductive agents. Power should be shut off if safe, and the fire department called for a growing fire.

Question 15Occupational Health and Safety

Why are ground fault circuit interrupter (GFCI) outlets required near salon sinks?

  1. They increase voltage for stronger dryers
  2. They convert AC current to DC current
  3. They prevent appliances from overheating
  4. They cut power when a ground fault occurs Correct answer.

Explanation

A GFCI monitors the current balance in a circuit and quickly shuts off power when it detects a ground fault, reducing the risk of electric shock in wet areas. It does not regulate appliance temperature or change the type of current.

Question 16Occupational Health and Safety

How should used razor blades be disposed of?

  1. In a recycling bin with other waste
  2. In a glass jar with a secure lid
  3. In the regular garbage wrapped in tissue
  4. In a puncture-proof sharps container Correct answer.

Explanation

Used blades are sharps and must go into a rigid, puncture-resistant sharps container that is closed and handled according to local rules. This protects staff and waste handlers from cuts and bloodborne-pathogen exposure.

Question 17Occupational Health and Safety

A client reports a latex allergy. What should the hairstylist use?

  1. Reusable rubber gloves
  2. Nitrile or vinyl gloves Correct answer.
  3. No gloves if hands are washed
  4. Powdered latex gloves

Explanation

Nitrile or vinyl gloves provide a latex-free barrier and reduce the risk of an allergic reaction. Latex-containing gloves and other latex items should be avoided for that client.

Question 18Occupational Health and Safety

If a chemical splashes into a client's eye, how long should the eye be flushed with clean water?

  1. 30 seconds
  2. 15 minutes Correct answer.
  3. 1 minute
  4. 5 minutes

Explanation

Eye splashes should be flushed with clean, lukewarm water for at least 15 minutes while holding the eyelids open. Medical attention should be sought afterward, and the SDS should be available for the responders.

Question 19Occupational Health and Safety

Which practice reduces exposure to formaldehyde during a smoothing treatment?

  1. Using it in a well-ventilated area with exhaust Correct answer.
  2. Wearing a surgical mask instead of a respirator
  3. Heating the product to increase effectiveness
  4. Keeping windows closed to contain fumes

Explanation

Formaldehyde is a respiratory irritant and carcinogen, so ventilation and local exhaust are key controls during smoothing treatments. Product directions and workplace exposure limits must be followed, and appropriate respiratory protection may be needed.

Question 20Occupational Health and Safety

What is the safe way to use aerosol hairspray near a client?

  1. Use near an open flame for faster drying
  2. Spray in a ventilated area and avoid the eyes Correct answer.
  3. Spray directly toward the face for even coverage
  4. Inhale deeply to test the scent

Explanation

Aerosol sprays should be used in a well-ventilated area with the nozzle directed away from the client's eyes and face. Inhaling the spray or using it near an ignition source can cause respiratory irritation or fire.

Question 21Occupational Health and Safety

A client has an open cut on the scalp. What should the hairstylist do before a chemical service?

  1. Double the developer strength to speed it up
  2. Cover the cut with cotton and proceed
  3. Apply the product directly over the cut
  4. Postpone the service and refer the client Correct answer.

Explanation

Chemical products can irritate or enter broken skin, increasing the risk of injury or infection. The service should be postponed until the scalp has healed, and medical advice should be recommended if needed.

Question 22Occupational Health and Safety

What should a hairstylist do first after a workplace injury?

  1. Ignore it if there is no visible blood
  2. Finish all clients before reporting it
  3. Wait until the end of the shift to report it
  4. Report it and get first aid Correct answer.

Explanation

Workplace injuries should be reported promptly so that first aid, investigation, and any required documentation can occur. Delaying reporting can worsen the injury and interfere with prevention efforts.

Question 23Occupational Health and Safety

How should leftover hair colour and developer be disposed of?

  1. Stored in an unlabelled container
  2. Mixed together and kept for later use
  3. Poured down the sink with plenty of water
  4. Per the manufacturer and local rules Correct answer.

Explanation

Chemical waste must be handled according to the manufacturer's instructions and local hazardous waste requirements. Many colour products should not be poured down the drain, and containers must remain labelled.

Question 24Occupational Health and Safety

When diluting a disinfectant concentrate, what should the hairstylist do?

  1. Mix two disinfectants for better results
  2. Guess the amount by colour
  3. Use hot water to increase strength
  4. Measure as directed and label it Correct answer.

Explanation

Disinfectants must be diluted exactly as the manufacturer directs to achieve the labelled concentration and contact time. The container should be labelled, and different disinfectants should not be combined.

Question 25Occupational Health and Safety

What is the first action when the fire alarm sounds in the salon?

  1. Collect all personal belongings first
  2. Finish the client's colour application
  3. Stop work and evacuate immediately Correct answer.
  4. Open windows to clear the smoke

Explanation

When the fire alarm sounds, work should stop and everyone should evacuate by the nearest safe route to the designated meeting area. Personal belongings and unfinished services are not worth delaying evacuation.

Question 26Occupational Health and Safety

Where should a hairstylist find safe handling, first-aid, and disposal information for a new colour product?

  1. The provincial exam guide
  2. Its Safety Data Sheet Correct answer.
  3. The salon booking ledger
  4. The client colour record

Explanation

The Safety Data Sheet is the manufacturer's document covering hazards, first aid, storage, and disposal for a product. Employers must make SDSs accessible to workers. Appointment logs and client records do not contain chemical safety information.

Question 27Occupational Health and Safety

How should a hairstylist clean their hands before starting a client service?

  1. Apply hand lotion only
  2. Wipe with a dry towel
  3. Wash with soap and warm water Correct answer.
  4. Rinse briefly with cold water

Explanation

Hands must be washed with soap and warm water before and after each client to prevent cross-contamination. Rinsing alone does not remove oils or microorganisms. A towel or lotion cannot clean hands effectively.

Question 28Occupational Health and Safety

Which footwear is most appropriate for a hairstylist working a full shift on a hard salon floor?

  1. Closed-toe non-slip shoes Correct answer.
  2. Smooth-soled fashion sneakers
  3. Open-toe sandals with cushioned soles
  4. High heels with leather uppers

Explanation

Closed-toe, non-slip shoes with arch support protect against spills, dropped tools, and slips, and reduce fatigue on hard floors. Open-toe or smooth-soled footwear increases injury risk. Supportive, slip-resistant footwear is a basic workplace control.

Question 29Occupational Health and Safety

A hairstylist has just mopped the floor near the shampoo sinks. What should be done while the floor dries?

  1. Ask clients to walk quickly
  2. Turn off the overhead lights
  3. Lay a dry towel over the area
  4. Place a wet-floor warning sign Correct answer.

Explanation

A wet-floor sign warns people of the slip hazard while the floor dries. Turning off lights or laying towels does not clearly warn and can create new hazards. Warning signs are a simple and effective control for a temporary slip hazard.

Question 30Occupational Health and Safety

What is the correct way to remove disposable gloves after a colour service?

  1. Peel gloves off inside out Correct answer.
  2. Rinse gloves then pull them off
  3. Blow into the gloves to loosen them
  4. Pull each glove off by its fingertips

Explanation

Gloves are removed by peeling one off inside out, then sliding fingers under the second glove to peel it off inside out without touching the contaminated exterior. This keeps the skin clean and prevents cross-contamination. Glove removal technique is part of standard precautions.

Question 31Occupational Health and Safety

A hairstylist notices the cord on a blow dryer is frayed and the wires are exposed. What should the hairstylist do?

  1. Wrap the fray with tape and continue
  2. Remove it from service and tag it Correct answer.
  3. Hold the cord away from the client
  4. Use it only on the lowest heat setting

Explanation

Frayed cords with exposed wires are an electrical shock and fire hazard. The equipment should be removed from service, tagged, and repaired or replaced by a qualified person. Continuing to use it exposes both stylist and client to risk.

Question 32Occupational Health and Safety

A hairstylist pours disinfectant into an empty water bottle for easy carrying. What is the main safety concern?

  1. Someone may mistake it for a drink Correct answer.
  2. The bottle will be too heavy to lift
  3. The bottle may melt in sunlight
  4. The disinfectant may lose its colour

Explanation

Disinfectants are hazardous and must stay in their original labelled containers or in properly labelled secondary containers. An unlabelled beverage bottle creates a serious poisoning risk. Labelling is a key part of chemical safety.

Question 33Occupational Health and Safety

A colour developer splashes onto a hairstylist's forearm and begins to sting. What should the hairstylist do first?

  1. Flush the skin with cool water Correct answer.
  2. Apply a thick layer of soothing lotion
  3. Wipe the area with a dry cloth
  4. Cover the whole area with a bandage

Explanation

Chemical splashes should be flushed with cool running water for at least 15 minutes, and contaminated clothing or jewellery removed. Medical advice should be sought if irritation persists. Lotions or tight bandages can trap the chemical.

Question 34Occupational Health and Safety

Why should a hairstylist never mix bleach with an ammonia-based cleaner?

  1. The mixture stains the sink
  2. It makes the cleaner evaporate faster
  3. It can release toxic chlorine gas Correct answer.
  4. The mixture loses its cleaning strength

Explanation

Mixing bleach with ammonia or ammonia-based cleaners produces chloramine gas, and with acids produces chlorine gas; both are toxic. Cleaners should never be combined. Chemical products must be used according to their labels.

Question 35Occupational Health and Safety

During consultation, a hairstylist sees circular scaly patches on a client's scalp that look like ringworm. What is the appropriate action?

  1. Proceed with the service and avoid the patches
  2. Apply disinfectant to the patches first
  3. Postpone and refer the client to a doctor Correct answer.
  4. Cut the hair short and continue

Explanation

Circular scaly patches suggest tinea capitis (ringworm), a contagious fungal infection. The service should be postponed and the client referred to a physician; tools and surfaces must be disinfected. Servicing a contagious client risks spreading infection to the stylist and other clients.

Question 36Occupational Health and Safety

A hairstylist develops wheezing and shortness of breath that worsen at work. What is the most appropriate response?

  1. Ignore it until it happens every day
  2. Report symptoms and seek medical assessment Correct answer.
  3. Open a window and continue without reporting
  4. Use a client's inhaler to control symptoms

Explanation

Worsening respiratory symptoms at work may indicate occupational asthma or sensitization to salon chemicals. Early reporting and medical assessment allow controls to be improved and prevent permanent damage. Employers have a duty to investigate workplace health concerns.

Question 37Occupational Health and Safety

A hairstylist is asked to use a chemical with no label or Safety Data Sheet. What does occupational health and safety law generally allow?

  1. Refuse until information is provided Correct answer.
  2. Use it only on a test strand
  3. Use the chemical at half strength
  4. Ask a coworker to use the chemical instead

Explanation

Workers generally have the right to refuse work they reasonably believe is unsafe, including when required hazard information is missing. The employer must investigate and provide the information. Unknown chemicals should never be used on clients or coworkers.

Question 38Occupational Health and Safety

What does disinfection of salon implements accomplish?

  1. It sterilizes the item completely
  2. It coats the item protectively
  3. It removes visible debris
  4. It kills most pathogens Correct answer.

Explanation

Disinfection destroys or inactivates most pathogenic microorganisms on non-porous implements, but it does not sterilize. Sanitation only removes visible debris. Sterilization kills all microorganisms, including spores, and requires different equipment.

Question 39Occupational Health and Safety

A glass bottle of developer shatters on the floor. What is the safest cleanup sequence?

  1. Pick up large pieces by hand, then vacuum
  2. Use a dustpan, then wipe and disinfect Correct answer.
  3. Sweep up all pieces with a broom and discard
  4. Flush the pieces into the sink with water

Explanation

Broken glass should be picked up with tongs or a dustpan, never bare hands, and the area wiped and disinfected. Vacuuming or flushing can injure or clog. The spilled chemical also needs safe cleanup per its SDS.

Question 40Occupational Health and Safety

A curling iron burns a client's neck during styling. What should the hairstylist do first?

  1. Pop any blister that forms
  2. Apply butter or oil to the burn
  3. Cover the burn tightly with cotton
  4. Cool the burn under running water Correct answer.

Explanation

Burns should be cooled under cool running water for about 10 to 20 minutes. Oils, butter, and ice can worsen tissue damage, and blisters should not be popped. Medical help should be sought if the burn is severe.

Question 41Client Consultation and Service

Which of the following is an open-ended question a stylist could use during a consultation?

  1. Are you here for a trim today?
  2. Did you color your hair in the past six months?
  3. Do you currently use a flat iron every day?
  4. What would you change about your hair if you could? Correct answer.

Explanation

Open-ended questions cannot be answered with a simple yes or no, so they encourage the client to describe needs, history and expectations in their own words. Closed questions are useful later in the consultation to confirm specific facts.

Question 42Client Consultation and Service

What is the main purpose of a patch test before an oxidative hair colour service?

  1. To confirm the shade will match the natural level
  2. To decide how much product to mix for the service
  3. To identify whether the client is sensitized to the dye Correct answer.
  4. To check how long the developer takes to activate

Explanation

A patch test detects an allergic sensitivity to the dye before the product is applied to the whole head, and it is normally performed 24 to 48 hours ahead. It does not predict the final shade, the speed of development or the quantity of product required.

Question 43Client Consultation and Service

Why should a stylist record the colour formula, developer and processing time on a client's record card?

  1. So the receptionist can book the correct appointment length
  2. To prove the client paid for the service
  3. To satisfy the product manufacturer's warranty
  4. So the result can be repeated or adjusted next visit Correct answer.

Explanation

An accurate record of the formula, developer, timing and result allows the stylist to reproduce a successful outcome or correct it deliberately at the next appointment. It also supports safe decision-making if the client reports a reaction.

Question 44Client Consultation and Service

A wet strand is stretched and does not return to its original length. This finding indicates:

  1. low elasticity and fragile hair Correct answer.
  2. high porosity that will accept colour quickly
  3. coarse texture that resists chemical change
  4. normal elasticity and readiness for lightening

Explanation

Healthy wet hair stretches and springs back to its original length; hair that stays stretched has lost elasticity and is structurally weak. Chemical services on such hair carry a high risk of breakage and should be modified or postponed.

Question 45Client Consultation and Service

Which finding during a scalp analysis requires the client to be referred to a physician before any service?

  1. A single small mole on the scalp
  2. A dry, flaky scalp with fine white dust
  3. Circular scaly patches with broken hairs Correct answer.
  4. Oily hair with a mild fragrance

Explanation

Circular scaly patches with broken hairs suggest a contagious fungal infection such as tinea capitis, which must be medically treated before service. The stylist should refer the client, decline the service and disinfect tools and contact surfaces.

Question 46Client Consultation and Service

A client says she used a 'natural henna' compound three weeks ago and now wants to be lightened. Why should the stylist be cautious?

  1. Henna permanently darkens the hair, so the client's target shade becomes impossible to reach
  2. Some henna products contain metallic salts that react with lightener Correct answer.
  3. Henna makes the hair too oily for the developer to work
  4. Henna removes the cuticle layer, so the hair cannot hold colour

Explanation

Some henna-based compounds are mixed with metallic salts, which can react unpredictably with lightener and cause severe breakage, melting or chemical burns. A test strand is essential, and if the reaction is unfavourable the lightening service should be declined.

Question 47Client Consultation and Service

Hair that wets quickly, dries quickly and feels rough when wet is best described as:

  1. high porosity with a raised cuticle Correct answer.
  2. resistant porosity with a closed cuticle
  3. low porosity and resistant to moisture
  4. normal porosity with a tight cuticle

Explanation

High-porosity hair has a raised, open cuticle that takes in and releases moisture rapidly, which is why it feels rough and dries quickly. It needs gentler, less alkaline products and a balance of protein and moisture to prevent further damage.

Question 48Client Consultation and Service

Why is a fresh neck strip used with the cape for every client?

  1. It stops hair and skin debris passing between clients Correct answer.
  2. It keeps the cape from slipping off the client's shoulders
  3. It protects the client's clothing from loose hair
  4. It absorbs excess water during shampooing

Explanation

The neck strip forms a barrier so that the cape never touches the client's skin directly, preventing hair, skin debris and moisture from being transferred from one client to the next. The cape itself is reused, but the neck strip is discarded after each service.

Question 49Client Consultation and Service

To determine a client's natural level, the stylist should assess the hair:

  1. at the ends, where the colour is darkest
  2. at the front hairline, where it is most exposed
  3. in the nape, after it has been lightened
  4. at the scalp (new growth) under consistent lighting Correct answer.

Explanation

The natural level is read from untreated new growth at the scalp, viewed under even, consistent lighting so that shadows and warm salon light do not distort the value. Ends and previously lightened areas carry old colour and do not represent the client's natural level.

Question 50Client Consultation and Service

Which information is most important to confirm before performing a relaxer service?

  1. Whether she wears contact lenses
  2. Her usual styling appointment day
  3. The date and type of her last relaxer Correct answer.
  4. Her preferred shampoo brand

Explanation

The date and type of the previous relaxer determine whether the hair is ready for another application and whether different relaxer systems would overlap. Overlapping incompatible or too-recent relaxers can cause severe breakage and scalp injury.
