CSLB General Building (B) — All Questions

California nail salons must bring their reusable implements to which level of decontamination?

• a.Sanitizing with soap and water only
• b.Sterilization in an autoclave
• c.Disinfection with an EPA-registered product after cleaning✓
• d.Wiping with 70 percent rubbing alcohol

Disinfection kills most pathogens on hard, non-porous surfaces and is the level California requires in nail salons. Soap and water only removes soil and is the first step, never a substitute. Sterilization destroys all microbial life including spores but is not required or practical for salon work, and rubbing alcohol is not a hospital-grade disinfectant.

A sales rep visits your salon with four products for soaking metal implements. Which one meets California requirements?

• a.A hospital-grade disinfectant registered with the EPA and labeled bactericidal, fungicidal and virucidal✓
• b.A scented household spray that advertises it cuts grease and grime
• c.A jar of 70 percent isopropyl alcohol
• d.Quaternary ammonium wipes sold for cleaning countertops

California requires an EPA-registered, hospital-grade disinfectant whose label carries bactericidal, fungicidal and virucidal claims. Household cleaners only clean and make no kill claim against pathogens. Alcohol and countertop quat wipes are not accepted substitutes for a hospital-grade implement disinfectant.U.S. EPA registration of disinfectants (FIFRA)

Your disinfectant label states a 10-minute contact time. You clean your metal nippers and then rest them in the tray with only the tips touching the solution for about three minutes. What is wrong?

• a.Nothing, because the nippers were cleaned first
• b.Three minutes is fine as long as you wipe them dry afterward
• c.Metal nippers should never be placed in a liquid disinfectant
• d.The implement must be completely immersed for the full contact time stated on the label✓

The label contact time is the minimum soaking time, and the whole implement must be under the solution. Any part above the liquid is never disinfected, and cutting the time short leaves live pathogens on the blades. Cleaning first is required but does not shorten the soak, and metal nippers are exactly the kind of non-porous tool meant to be immersed.CCR Title 16 §979

Which statement about sterilization is accurate for a nail salon?

• a.A salon disinfectant sterilizes implements if you leave them soaking overnight
• b.Sterilization destroys all microbial life including bacterial spores and requires equipment such as an autoclave✓
• c.Sterilizing and sanitizing mean the same thing
• d.Boiling implements in water for five minutes sterilizes them

Sterilization destroys every form of microbial life, spores included, and requires an autoclave; it is not required for California nail services. Leaving tools in disinfectant longer does not turn disinfection into sterilization. Sanitizing is only the soap-and-water removal of soil, and boiling does not reliably destroy spores.

You just finished a manicure and your metal cuticle pusher has visible debris and oil on it. What must happen before it goes into the disinfectant?

• a.Wash it with soap and water, scrub off the debris, and rinse it✓
• b.Wipe it on a dry towel and drop it straight in
• c.Leave it in the solution twice as long to make up for the debris
• d.Spray it with alcohol and let it air dry

Cleaning with soap and water and rinsing is the required first step, because debris and oil shield germs so the disinfectant cannot reach them. Wiping on a towel or spraying alcohol does not remove that film. Doubling the soak time does not fix a dirty implement, and the soil also breaks down the solution for every tool in the jar.CCR Title 16 §979

A pedicure is finished. Which group of items must all be thrown away because they cannot be disinfected?

• a.Metal toenail clippers, metal pusher and stainless steel tweezers
• b.Glass bowl, metal file handle and metal drill bit
• c.Emery board, wooden pusher, foam toe separators and pumice stone✓
• d.Manicure table, armrest and the lamp handle

Those items are porous, so disinfectant cannot penetrate them and they are single-use, going in the trash after one client. Metal and glass items are non-porous and are cleaned and disinfected for reuse. The table, armrest and lamp are surfaces that get cleaned and disinfected, not discarded.

Midway through a busy Saturday you notice the disinfectant in your jar has turned cloudy with bits of nail dust floating in it. What is required?

• a.Add fresh concentrate to the jar to strengthen what is already there
• b.Empty the jar, clean it, and mix a fresh batch according to the label✓
• c.Strain the debris out and keep using the same solution
• d.Keep using it until closing time and change it at the end of the day

Cloudy or visibly dirty solution is no longer effective and must be discarded and replaced with a freshly mixed batch, and the container itself has to be cleaned. Topping off or straining does not restore the kill power, because organic soil neutralizes the active ingredient. Waiting until closing means every client until then receives tools that were never truly disinfected.CCR Title 16 §979

Which of these items may be cleaned, disinfected and used on the next client?

• a.The buffer block used to shine the nails
• b.The orangewood stick used to push back dead tissue
• c.The foam slippers the client wore
• d.The stainless steel nipper used on a hangnail✓

A stainless steel nipper is non-porous, so it can be washed, rinsed, fully immersed in disinfectant for the label contact time and reused. Buffer blocks, wooden sticks and foam slippers are porous and soak up moisture and debris, so disinfectant cannot reach the germs inside them and they are discarded after one client.

To be used on nail implements in California, a disinfectant label must show that the product kills which three groups of organisms?

• a.Bacteria, fungi and viruses✓
• b.Bacteria, spores and insects
• c.Viruses, spores and mold only
• d.Fungi and dust mites only

The label must carry bactericidal, fungicidal and virucidal claims, meaning the product kills bacteria, fungi and viruses, which are the pathogens that actually pass between clients in a salon. Killing bacterial spores is sterilization, which salon disinfectants do not claim. Insects and dust mites have nothing to do with disinfectant efficacy claims.U.S. EPA registration of disinfectants (FIFRA)

You lift your disinfected metal implements out of the solution with tongs and dry them. Where do they belong now?

• a.Back in the disinfectant jar so they stay wet until the next client
• b.In a clean, closed, labeled dry container reserved for disinfected implements✓
• c.Loose in the top drawer alongside the used tools from this morning
• d.In an open tray on the manicure table

Disinfected implements are dried and stored in a clean, covered container that is labeled as clean or disinfected and kept separate from used tools. Leaving them sitting in the solution can corrode them and the solution weakens over time. An open tray or a drawer shared with dirty tools recontaminates them before the next client even sits down.CCR Title 16 §979

Why must disinfectant concentrate be measured and mixed exactly as the manufacturer's label directs?

• a.A stronger mix always disinfects faster, so more concentrate is preferred
• b.The dilution only affects how strongly the product smells
• c.Too weak will not kill the pathogens, and too strong can damage implements and irritate skin and lungs✓
• d.The label ratio is only a suggestion as long as tools soak overnight

The EPA registration is based on the exact dilution and contact time on the label, so any other mix is unproven and using it is a violation. An under-diluted solution leaves pathogens alive, while an over-concentrated one can pit and corrode implements and irritate skin and airways. Soaking longer does not rescue a solution that was mixed wrong.

Your electric file handpiece and the handle of your table lamp cannot be put in liquid. How are they disinfected between clients?

• a.Clean off the dust, then wipe or spray them with an EPA-registered disinfectant and keep the surface visibly wet for the label's contact time✓
• b.Blow the dust off with compressed air and move on
• c.Immerse them in the same jar used for the metal implements
• d.They need no disinfection because they never touch the client's skin

Non-immersible electrical items are first cleaned of dust and residue, then wiped or sprayed with an EPA-registered disinfectant that must stay visibly wet on the surface for the full contact time. Immersing an electrical item destroys it and creates a shock hazard. Compressed air just scatters contaminated dust, and both items are handled constantly, so they do require disinfection.CCR Title 16 §980

A regular client asks you to keep her favorite emery board in a drawer with her name on it for her next visit. What should you do?

• a.Write her name on it and store it in the client drawer
• b.Soak it in disinfectant for ten minutes and then store it
• c.Brush the dust off and seal it in a plastic bag with her name
• d.Explain that a used porous file cannot be disinfected, and either give it to her to take home or discard it✓

A file is porous, so disinfectant cannot reach the germs trapped in the abrasive surface, and it is single-use in the salon. Naming, bagging or soaking it keeps a contaminated item in service and would be cited by an inspector. The acceptable outcomes are to hand the used file to the client to take home or to throw it away.

One client has just left and the next one is sitting down. What is the single most effective thing you can do to stop the spread of infection?

• a.Pull on a fresh pair of gloves without washing first
• b.Wash your own hands with soap and warm water before touching the next client✓
• c.Have the client rub hand sanitizer on her hands
• d.Change the towel on the armrest

Hand washing with soap and warm water is the single most effective infection-control measure, and it is done before and after every client, after handling used implements and after any break. Gloves pulled over unwashed hands still spread germs to the table, the tools and the product jars. Client sanitizer and a fresh towel help, but neither replaces washing your own hands.

Which statement about viruses in a salon setting is correct?

• a.HIV survives for weeks on a countertop and is the main salon concern
• b.Viruses cannot be carried on implements, only through the air
• c.Hepatitis B survives on surfaces longer than HIV, which makes it the greater salon risk✓
• d.Hepatitis B is destroyed by soap and water alone

Hepatitis B is hardy outside the body and survives on contaminated surfaces and implements far longer than HIV, so it is the greater practical risk in a nail salon. HIV is fragile once it leaves the body. Implements and surfaces certainly can carry viruses, and soap and water only cleans; an EPA-registered disinfectant labeled virucidal is what inactivates the virus.

You file acrylic all day and the trash at your station is an open basket of acetone-soaked cotton. What should you change?

• a.Use a covered waste can with a self-closing metal lid, empty it daily, and wear an N95-type dust mask while filing✓
• b.Aim a ceiling fan at your station to move the vapors around the room
• c.Rely on the dust mask alone to protect you from the acetone vapors
• d.Prop the front door open and leave the basket where it is

Chemical-soaked cotton belongs in a covered waste container with a self-closing metal lid that is emptied every day, and an N95-type mask should be worn for filing dust. A ceiling fan only stirs vapors around instead of capturing them at the table, which is what source-capture ventilation does. A dust mask filters particles, not vapors, so it cannot be your protection against acetone fumes.

Your last client has left and there is filing dust and a smear of lotion on the manicure table and the armrest. What is the correct procedure before the next client?

• a.Cover the table with a clean towel and begin the next service
• b.Spray disinfectant over the dust and wipe it off right away
• c.Vacuum the dust and wipe the table with a damp paper towel
• d.Clean the surfaces with soap and water first, then apply disinfectant and let it stay wet for the label's contact time✓

A work surface must be cleaned of dust, lotion and product residue before the disinfectant goes on, and the disinfectant then has to remain visibly wet for the labeled contact time. Wiping it off immediately ends the contact time before it can kill anything. Covering soil with a towel or only damp-wiping leaves the contamination sitting under the next client's hands.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

What is required of a California nail salon regarding Safety Data Sheets?

• a.They are needed only for products labeled flammable
• b.An SDS must be kept on the premises for every chemical product and be available to employees and inspectors✓
• c.They stay at the manufacturer's office and are requested only after an accident
• d.Only the salon owner is permitted to read them

An SDS must be kept at the salon for every chemical product used or stored there, and employees as well as Board and Cal/OSHA inspectors must be able to look at them. Each sheet lists the hazards, ingredients, first aid, safe handling, storage and required protective equipment. They are not limited to flammable products, they are not kept offsite, and every employee has the right to read them.Cal/OSHA Hazard Communication Standard (8 CCR §5194)

You have just finished a pedicure and your next client is already waiting. Before that client puts her feet in the same foot spa, what must you do?

• a.Drain the water, spray the inside of the basin with alcohol, and wipe it dry with a clean towel.
• b.Drain the water, refill with hot soapy water, and let it circulate while you walk the first client to the front desk.
• c.Drain the basin, remove and clean the screen or filter and the area behind it, scrub the basin with soap, rinse, then refill with water and an EPA-registered disinfectant and circulate it for the full contact time on the label before draining and air drying.✓
• d.Drain the basin, wipe it with a disinfectant wipe, and save the full cleaning for closing time.

The complete procedure in option C is required after every single client, because only circulating an EPA-registered disinfectant for the label contact time kills the bacteria and fungus left behind. Alcohol is not a hospital-grade salon disinfectant and never reaches the debris behind the screen, so A fails. Soapy water only cleans, it does not disinfect (B), and end-of-day cleaning does not replace the between-client procedure (D).California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

An inspector watches a technician empty a pedicure tub, wipe it out with a paper towel, and refill it for the next client. Why is this a violation?

• a.The tub should have been refilled with distilled water instead of tap water.
• b.The technician used a paper towel instead of a clean cloth towel.
• c.The tub must be dried with a fan before it can be refilled.
• d.Wiping only removes what you can see; the basin was never scrubbed with soap and no EPA-registered disinfectant was ever circulated for the label contact time, so organisms in the screen, the jets and the plumbing are still alive.✓

Draining and wiping is a cleaning step, not disinfection, so answer D describes the real problem: the pathogens most likely to infect the next client hide in the filter area and the water lines, which a towel never touches. The type of water (A) and the type of towel (B) are not what the rule addresses. Air drying is required after the disinfectant is drained, but a fan (C) is not a substitute for the disinfection step itself.

It is closing time and you are in charge of the two pedicure chairs. What does the end-of-day foot spa procedure require?

• a.Remove the screen or filter, clean out all the trapped debris, scrub the screen and the surface behind it with soap and water, put it back, then refill with water and disinfectant, circulate for the full contact time, drain and air dry.✓
• b.Fill the tub with very hot water and circulate it for an hour to flush the pipes.
• c.Wipe the outside of the chair and the footrest with a disinfectant wipe and leave the basin empty and dry.
• d.Pour undiluted bleach into the empty basin and leave it there until morning.

The end-of-day routine in option A is built around opening up the screen or filter, because that is where hair, skin and product collect and feed bacteria overnight. Hot water alone (B) has no disinfecting power. Wiping the outside of the chair (C) ignores the basin entirely, and undiluted bleach sitting in an empty basin (D) is not a labeled use, damages the equipment and does not replace the required circulated disinfection.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

Every Sunday night your salon performs the extra foot spa cleaning that is required at least once a week. After the normal daily cleaning is finished, what happens next?

• a.The tub is filled with water and disinfectant, circulated for thirty minutes, and drained right away.
• b.The tub is filled with plain hot water and left overnight, then drained in the morning.
• c.The tub is filled with water and disinfectant (or a low-foaming bleach solution where the label allows it), and that solution is left sitting in the tub overnight for at least six hours without circulating, then drained, flushed with clean water and air dried.✓
• d.The jets and the screen are pulled out and soaked in acetone overnight.

The weekly step is defined by the long soak: the solution has to sit undisturbed in the tub for at least six hours, which is what makes option C correct, and then the tub is drained, flushed and air dried. A thirty-minute circulation (A) is only the daily level of cleaning. Plain hot water (B) has no disinfecting action, and acetone (D) is a solvent for product, not a disinfectant, and would damage the equipment.

A Board inspector walks in without notice and asks to see the records for your pedicure spas. What must you be able to produce?

• a.Receipts showing you bought disinfectant within the last thirty days.
• b.A dated cleaning record for each foot spa showing what cleaning was done and who did it.✓
• c.A signed note from each client saying the tub looked clean.
• d.The manufacturer's warranty card and installation paperwork for each pedicure chair.

Each foot spa must have its own dated cleaning log that is kept in the salon and shown to the inspector on request, which is what option B describes. Purchase receipts (A) prove you own disinfectant but not that any tub was ever cleaned. Clients are not responsible for verifying disinfection (C), and warranty paperwork (D) has nothing to do with health and safety compliance.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

How does the required cleaning and disinfection routine for a pipeless pedicure tub compare with the routine for a whirlpool tub that has jets and plumbing?

• a.It is the same requirement for both: cleaned and disinfected after every client, at the end of every day, and at least once a week, because both hold water against a client's skin and both trap debris.✓
• b.A pipeless tub only needs to be wiped out, because there is no plumbing where bacteria can hide.
• c.A whirlpool tub needs only the weekly service; a pipeless tub needs the after-client service.
• d.A pipeless tub needs disinfecting only when a client has broken skin.

Both styles of tub follow the identical schedule, so option A is correct: a pipeless unit still has an impeller, a screen and a basin surface where skin, hair and product collect. Believing the pipeless design is self-cleaning (B) is one of the most common salon mistakes and a frequent citation. Options C and D invent a lighter standard that does not exist for either tub.

A client sits down for a pedicure and you see a fresh razor cut on her lower leg from shaving that morning; the skin is still open. What should you do?

• a.Go ahead with the pedicure but keep the water level below the cut.
• b.Cover the cut with a bandage and perform the whole service, including the soak.
• c.Dab antiseptic on the cut and start the soak.
• d.Keep her foot and leg out of the foot spa, explain that an open break in the skin is an easy way for bacteria to get in, and offer a waterless pedicure or reschedule once the skin has healed.✓

Broken skin removes the body's main barrier, and warm circulating spa water is exactly where an organism can enter, so option D is the safe and professional choice. Lowering the water (A) does not control splashing or the wet leg rest. A bandage (B) does not stay sealed in water, and antiseptic (C) does not close the wound or make the tub safe for a fresh cut.

While you are trimming a hangnail, the nipper nicks the client's skin and it starts to bleed. What is the correct thing to do?

• a.Press the shop's styptic pencil directly on the cut and keep working.
• b.Stop the service immediately, put on gloves, clean the injury, apply an antiseptic, and cover it with a bandage or a finger guard before deciding whether to continue.✓
• c.Finish the nail first so the polish is not ruined, then clean the cut.
• d.Rinse the finger at the sink and keep going bare-handed because it is only a drop of blood.

Option B is the required sequence: stop, glove up, clean, antiseptic, cover, and only then decide about continuing. A shared styptic pencil or alum block touches one client's blood and then the next client's, which is prohibited; use a powder or liquid styptic applied with a disposable applicator, so A is wrong. Continuing to work (C) or handling blood bare-handed (D) exposes both of you to bloodborne pathogens such as hepatitis B.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

After you bandage the client's finger, your table has a cotton ball, a gauze square and a paper towel with blood on them. How do you dispose of them?

• a.Drop them into the open wastebasket under the table with the rest of the day's trash.
• b.Rinse the blood off in the sink and then throw them away.
• c.Double-bag them and place them in a sealed bag or a closed, covered container kept for contaminated waste.✓
• d.Soak them in disinfectant for ten minutes and reuse them on the same client.

Single-use items with blood on them are contaminated waste: double-bag them and put them in a sealed bag or closed container, which is option C. An open trash can (A) lets contaminated cotton be touched by the next person who empties it. Rinsing blood into the salon sink (B) spreads it to a surface used for washing hands, and porous items like cotton and gauze can never be disinfected and reused (D).Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

The metal nipper that caused the nick has blood on the blade. What do you do with that implement?

• a.Clean it with soap and water, then fully immerse it in an EPA-registered disinfectant labeled effective against HIV and hepatitis B — or in a 10% bleach solution — for the contact time on the label.✓
• b.Wipe the blade with a 70% alcohol pad and put it back in your tool drawer.
• c.Put it straight into the disinfectant jar without washing it, since the disinfectant will dissolve the blood.
• d.Throw it away, because any implement that touches blood can never be used again.

Option A is the required two-step handling: clean first so blood and debris cannot shield organisms, then fully immerse in a disinfectant with an HIV and hepatitis B claim (or 10% bleach) for the full label contact time. An alcohol wipe (B) does not meet that standard for a blood-contaminated tool. Skipping the cleaning step (C) leaves protein on the blade that blocks the disinfectant, and a metal nipper is non-porous and does not have to be discarded (D).Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

Why is MMA (methyl methacrylate) monomer prohibited in nail products in California?

• a.It cures too slowly, and clients will not sit still long enough for it to harden.
• b.It costs much more than the approved monomers.
• c.It does not hold color well and turns yellow in sunlight.
• d.It bonds far too aggressively and cures far too hard, so the enhancement will not soak off — the natural nail plate tears, thins or lifts off with it — and it can cause allergic contact dermatitis and lasting nail damage.✓

Option D states the real reason: MMA is not a nail-product monomer, it grips harder than the nail plate itself, so the nail gives way before the product does, and repeated exposure sensitizes the skin. EMA (ethyl methacrylate) is the accepted monomer for salon use. MMA is actually cheap and cures quickly, which is exactly why some shops use it, so A and B are backwards, and yellowing (C) is a cosmetic issue, not the reason for the ban.

A new client says that at her last salon the acrylic would not dissolve in acetone, the technician had to grind it off with a very coarse drill bit, the set felt unusually hard and heavy, and the shop had a strong strange odor. What do these signs point to?

• a.The salon used UV gel instead of liquid and powder.
• b.The salon used too much acid primer under the product.
• c.The salon was very likely using MMA, which is prohibited in California nail products.✓
• d.The salon used a polymer powder that was past its expiration date.

Those four clues together — will not soak off in acetone, needs an aggressive drill, unusually hard and heavy, strong odd odor — are the classic warning signs of MMA, so option C is correct. UV gel (A) also has to be filed off, but it does not create that odor or that weight and it is legal. Too much acid primer (B) burns the nail plate but does not change how the product dissolves, and expired powder (D) causes slow curing and discoloration, not indestructible product.

The owner of the salon where you just started hands you an unlabeled jug of monomer with a very strong odor and tells you to use it because it lasts longer and costs less. What should you do?

• a.Use it during your shift but keep your own EMA monomer for your regular clients.
• b.Refuse to use it, tell the owner the product is prohibited in California, and report the salon to the Board of Barbering and Cosmetology.✓
• c.Use it only on clients who ask for the strongest possible set, and warn them about the smell.
• d.Use it but wear a dust mask and prop the back door open for ventilation.

Option B is the only correct answer: a prohibited product stays prohibited no matter who tells you to use it, and it is your license that is on the line along with your clients' nails. Using it part of the time (A and C) is still using it, and a client cannot consent to a banned product. A dust mask (D) filters dust, not vapors, and no amount of fresh air makes an illegal monomer legal.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

A regular client points at the thick callus on her heel and asks you to just shave it off with a credo blade the way her last salon did. What is the correct response?

• a.Explain that credo blades and razor-type callus shavers are prohibited in California and that cutting living skin is outside a manicurist's scope, then reduce the callus with a foot file or rasp instead.✓
• b.Use the credo blade only on the thickest part, where she cannot feel anything.
• c.Use the credo blade and then disinfect it thoroughly afterward.
• d.Use the blade but put in a brand-new disposable blade so it is sanitary.

Answer A is correct because the tool itself is prohibited and because slicing living tissue is a medical act a manicurist may not perform. Thick callus still has living skin under it, so B is not safer, it just makes the injury harder for the client to notice. Disinfecting afterward (C) and using a fresh blade (D) address contamination only; they do not make a prohibited procedure legal or stop the cutting injury.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)

During a pedicure you find a corn on the side of one toe, a deep cracked callus on the heel, and a toenail growing down into the flesh that is tender to the touch. What is within your scope of practice?

• a.Cut the corn out and lift the ingrown nail edge free with a curved probe.
• b.Trim the ingrown corner of the nail and file the corn down level with the skin.
• c.Smooth the callus with a foot file only, leave the corn and the ingrown nail alone, and refer the client to a podiatrist.✓
• d.Soak the foot longer so the tissue softens, then remove all three with a nipper.

Option C is the correct scope: a manicurist may reduce callus with a foot file, but a corn and an ingrown toenail involve living tissue and belong to a podiatrist. Cutting or probing an ingrown nail (A and B) is a medical procedure and a common cause of serious infection. Soaking softens tissue but changes nothing about scope, so D would still be cutting living skin.

A new client takes off her socks and the skin around one big toenail is red, swollen, warm and has a small amount of pus. What should you do?

• a.Service the other nine toes and simply skip that one.
• b.Tell her she has a nail infection and recommend an antifungal cream from the drugstore.
• c.Do the pedicure anyway and disinfect the tub twice afterward.
• d.Politely decline the service, describe only what you see without naming a condition, explain that you are not allowed to work on inflamed or infected skin, and suggest she see a physician.✓

Redness, swelling, heat and pus are signs of an active infection, so option D is the professional response: describe, decline, refer, and never diagnose. Skipping one toe (A) does not help because the spa water, the towels and your implements still contact the infected area and the rest of the foot. Naming a disease and recommending medication (B) is diagnosing, which is outside your scope, and extra tub cleaning (C) protects the next client but still exposes this client to a worse infection.

Which manicuring station is set up the way California health and safety rules require?

• a.An open wastebasket for used cotton, a coffee cup on the table, and monomer poured into a clean drinking-water bottle so it is easier to pour.
• b.A covered waste container with a self-closing lid for chemical-soaked cotton, every product in its original labeled and closed container, and no food, drink or smoking at the table.✓
• c.A covered waste container, an unlabeled squeeze bottle of acetone, and a snack kept in the drawer.
• d.An open trash can emptied every night, drinks allowed as long as they have a lid, and a scented candle burning to cover the product odor.

Option B meets all three requirements at once: solvent-soaked cotton goes in a covered self-closing container, chemicals stay in closed original containers with their labels, and food, drink and smoking stay away from the products. Putting monomer in a drinking bottle (A) and leaving acetone unlabeled (C) are exactly how accidental poisonings happen, and an unlabeled container also breaks the labeling rule. An open flame near acetone and monomer vapors (D) is a fire hazard, and a candle only masks odor instead of removing vapor.California Board of Barbering and Cosmetology Health and Safety Regulations (CCR Title 16)
