CSLB General Building (B) — All Questions

What is the primary difference between sanitation and disinfection?

• a.They both destroy all microbial life including spores
• b.Sanitation reduces the number of germs to a safe level, while disinfection destroys most pathogens on non-living surfaces✓
• c.Sanitation destroys pathogens, while disinfection only removes visible dirt
• d.There is no practical difference between the two terms

Sanitation lowers the level of germs on a surface to a level considered safe, typically by cleaning with soap and water. Disinfection goes further, destroying most disease-causing organisms on hard non-porous surfaces, though it does not necessarily kill bacterial spores.CCR Title 16 §979

Which level of decontamination destroys ALL microbial life, including bacterial spores?

• a.Sanitation
• b.Disinfection
• c.Sterilization✓
• d.Deodorizing

Sterilization is the complete destruction of all microbial life, including highly resistant bacterial spores. It generally requires an autoclave or a comparable process and is not routinely achievable with the liquid disinfectants used in a barbershop.CCR Title 16 §979

Before any implement can be effectively disinfected, it must first be:

• a.Thoroughly cleaned to remove all visible debris, hair, and residue✓
• b.Rinsed only in cold running water
• c.Wrapped in a paper towel
• d.Stored in a closed drawer overnight

Disinfectants cannot penetrate dirt, oils, or hair debris, so an implement must be cleaned with soap and water first. Cleaning removes the organic matter that would otherwise shield microbes and neutralize the disinfectant.CCR Title 16 §979

A disinfectant used on barbering implements should be:

• a.Any household bleach diluted at random
• b.EPA-registered and used according to the manufacturer's label instructions✓
• c.A fragrance-only barbicide substitute
• d.Rubbing alcohol below 50 percent strength

California requires that disinfectants be registered with the U.S. Environmental Protection Agency (EPA) and used exactly as directed on the label. The label specifies dilution, contact time, and the organisms the product is proven to kill.CCR Title 16 §979

The 'contact time' listed on a disinfectant label refers to:

• a.How long the product may sit unopened on a shelf
• b.The time needed to mix the solution
• c.How long an implement must dry after disinfection
• d.The full time an implement must stay wet with the solution to kill the listed organisms✓

Contact time, also called dwell or wet time, is the number of minutes the surface or tool must remain visibly wet with the disinfectant for it to work. Removing the tool early means pathogens may survive, so the manufacturer's stated time must be met.CCR Title 16 §979

Which disinfectant type is commonly used in barbershops for non-electrical implements?

• a.Plain tap water
• b.Hair conditioner
• c.An EPA-registered quaternary ammonium or equivalent hospital-level disinfectant✓
• d.Petroleum jelly

Quaternary ammonium compounds ('quats') and other EPA-registered hospital-grade disinfectants are widely used to immerse combs, shears, and clips. They must be mixed to label strength and replaced when they become cloudy or contaminated.CCR Title 16 §979

How should combs and brushes be handled before being placed in disinfectant solution?

• a.Hair and debris should be removed and they should be washed with soap and water✓
• b.They should be placed in the solution still full of hair
• c.They should be heated in a microwave
• d.They should be wiped with a dry towel only

Loose hair and product must be removed and the tools cleaned with soap and water before immersion. Otherwise organic debris protects microbes and weakens the disinfectant, defeating the process.CCR Title 16 §979

Disinfected implements must be stored in a manner that keeps them:

• a.Loose in a pocket or apron
• b.Clean and dry in a covered, disinfected container or drawer✓
• c.Submerged permanently in used solution
• d.Piled together with soiled tools

Once disinfected and dried, tools must be stored in a clean, covered, and labeled container that protects them from contamination. Mixing them with soiled implements would re-contaminate them.CCR Title 16 §979

A disinfectant solution in a jar should be changed:

• a.Once a year
• b.Only when it runs out
• c.Never, as long as it looks clear
• d.When it becomes visibly dirty or cloudy, as directed by the manufacturer, and at least daily in many products✓

Used disinfectant becomes contaminated with debris that reduces its effectiveness. It must be discarded and replaced when it appears dirty or cloudy, and most labels require fresh solution at least once each day.CCR Title 16 §979

The correct first step when a client is accidentally cut and blood is present is to:

• a.Stop the service, put on gloves, and control the bleeding✓
• b.Continue cutting and clean up later
• c.Reuse the same razor on the next client
• d.Wipe the blood with a bare hand

When an exposure incident occurs, the barber must stop, don single-use gloves, and address the wound following universal precautions. This protects both the client and the barber from bloodborne pathogen exposure.CCR Title 16 §979

After a blood spill on a workstation surface, the area must be:

• a.Left to air dry with no cleaning
• b.Covered with a towel and used again
• c.Cleaned and then disinfected with an EPA-registered disinfectant effective against bloodborne pathogens (tuberculocidal or equivalent)✓
• d.Sprayed only with water

Any surface contaminated with blood must be cleaned of visible matter and then disinfected with a product labeled effective against HIV, HBV, and other bloodborne pathogens. Contaminated disposable materials must be double-bagged or placed in a proper container.CCR Title 16 §979

Items contaminated with blood, such as gauze or tissue, should be:

• a.Reused after wiping
• b.Placed in a sealed or double-bagged container and disposed of properly✓
• c.Left on the counter
• d.Rinsed and returned to the drawer

Blood-soiled disposables are potentially infectious and must be discarded in a closed, leak-proof bag or a designated container. This prevents anyone from contacting the contaminated material.CCR Title 16 §979

'Universal precautions' means treating:

• a.Only clients who appear ill as infectious
• b.Only clients who disclose an illness as infectious
• c.No client as a source of infection
• d.All human blood and body fluids as if they are potentially infectious✓

Universal (or standard) precautions require that every person's blood and body fluids be treated as potentially infectious because carriers cannot be identified by appearance. This drives consistent use of gloves, disinfection, and safe disposal for every client.CCR Title 16 §979

A straight razor with a permanent (non-replaceable) blade used in barbering must be:

• a.Cleaned and disinfected with an EPA-registered disinfectant between every client✓
• b.Only wiped on a towel between clients
• c.Never disinfected because steel resists germs
• d.Disinfected only at the end of the week

A fixed-blade straight razor cannot be discarded, so it must be cleaned and then immersed in or wiped with an appropriate EPA-registered disinfectant after each use. This prevents transfer of bloodborne pathogens between clients.CCR Title 16 §979

Disposable (single-use) razor blades and other single-use items must be:

• a.Reused on the same client's next visit
• b.Discarded after one use, with blades placed in a puncture-resistant sharps container✓
• c.Disinfected and reused on other clients
• d.Stored in the disinfectant jar between clients

Single-use blades cannot be adequately disinfected and are designed to be thrown away after one client. Used blades are sharps and must go into a puncture-proof container to protect against injury and exposure.CCR Title 16 §979

Which of the following is a PROHIBITED practice in a California barbershop?

• a.Using EPA-registered disinfectant on shears
• b.Storing clean towels in a covered cabinet
• c.Using a razor or implement on a client's skin that has an open sore or is broken✓
• d.Cleaning combs before disinfection

Barbers may not perform services on skin that is inflamed, broken, or shows signs of infection; the client should be referred to a physician. Working on such skin risks spreading infection and injuring the client.CCR Title 16 §979

Powders, lotions, and creams should be dispensed in a way that:

• a.Avoids contaminating the remaining product, using a clean spatula or shaker rather than fingers✓
• b.Uses the same fingers dipped repeatedly
• c.Returns unused product to the container
• d.Shares one applicator among all clients without cleaning

Multi-use products must be removed with a clean spatula, pump, or shaker so fingers never touch the bulk supply. Any product removed and not used must be discarded, never returned to the container.CCR Title 16 §979

Which practice best reduces the spread of infection in a barbershop?

• a.Reusing neck strips between clients
• b.Skipping handwashing when busy
• c.Storing dirty tools with clean tools
• d.Washing hands before and after each client✓

Frequent, thorough handwashing is one of the most effective ways to prevent transmission of pathogens. Barbers should wash before and after every client and any time hands become soiled.CCR Title 16 §979

A clean towel or neck strip is used to:

• a.Wrap tools for storage only
• b.Prevent the shampoo cape from directly touching the client's skin✓
• c.Wipe down the floor
• d.Clean the disinfectant jar

A fresh neck strip or towel placed between the cape and the client keeps the cape from touching the neck, so a used cape does not contact bare skin. A clean strip or towel must be used for each client.CCR Title 16 §979

An SDS (Safety Data Sheet) provides information primarily about:

• a.A client's medical history
• b.Haircut pricing
• c.The hazards, safe handling, and first-aid for a chemical product✓
• d.The barber's license expiration

A Safety Data Sheet lists a product's ingredients, health and physical hazards, storage, and emergency measures. Shops must keep SDS documents accessible so staff know how to handle chemicals safely.Cal/OSHA Hazard Communication Standard

Good ventilation in a barbershop is important because it:

• a.Reduces buildup of chemical fumes and airborne particles✓
• b.Increases the strength of disinfectants
• c.Eliminates the need to clean tools
• d.Makes hair grow faster

Proper ventilation removes vapors from products such as disinfectants, aerosols, and chemical services, protecting the respiratory health of workers and clients. It does not replace disinfection or cleaning duties.Cal/OSHA General Industry Safety Orders

Electrical clippers and trimmers that cannot be immersed in liquid should be:

• a.Soaked fully in disinfectant
• b.Never cleaned
• c.Rinsed under running water
• d.Cleaned of hair and disinfected with an EPA-registered spray or wipe designed for that use✓

Because immersing an electrical tool would damage it and create a shock hazard, clipper blades are cleaned of hair and then treated with an approved disinfectant spray or wipe. Detachable blades may also be removed and disinfected separately per manufacturer directions.CCR Title 16 §979

Which is an example of a bloodborne pathogen of concern in a barbershop?

• a.The common cold virus
• b.Hepatitis B virus (HBV)✓
• c.Athlete's foot fungus
• d.Head lice

Hepatitis B and C viruses and HIV are bloodborne pathogens that can be transmitted through contact with infected blood, such as from a razor nick. This is why disinfection of blades and universal precautions are essential.CCR Title 16 §979

When mixing a disinfectant concentrate, the barber should:

• a.Guess the amount
• b.Always use more concentrate than directed for extra strength
• c.Follow the exact dilution ratio on the manufacturer's label✓
• d.Dilute it with used solution

Disinfectants must be mixed to the precise dilution stated on the label. Too weak a mixture fails to kill pathogens, while too strong a mixture wastes product, can damage tools, and may create a health hazard.CCR Title 16 §979

Wet sanitizers or disinfectant containers used for immersing tools must be:

• a.Covered and large enough to fully submerge the implements✓
• b.Left uncovered at all times
• c.Only deep enough to cover the tips
• d.Shared with food items

An immersion container must hold enough solution to completely cover the implements and should be kept covered to reduce evaporation and contamination. Partial immersion leaves part of the tool untreated.CCR Title 16 §979

A client arrives with an obvious contagious skin condition on the scalp. The barber should:

• a.Perform the service quickly
• b.Use extra disinfectant and proceed
• c.Ignore it if the client insists
• d.Decline the service and refer the client to a physician✓

Barbers are not permitted to service a client showing signs of a contagious or infectious condition. The correct action is to politely decline and recommend the client see a physician, protecting other clients and staff.CCR Title 16 §979

The main reason a barber wears single-use gloves during a shave that draws blood is to:

• a.Improve grip on the razor only
• b.Create a barrier against contact with blood and bloodborne pathogens✓
• c.Keep the hands warm
• d.Make the service faster

Gloves form a protective barrier that prevents the barber's skin from contacting the client's blood. They are removed and discarded after the incident, and hands are washed, following universal precautions.CCR Title 16 §979

Which statement about a barber's hands and fingernails is correct for infection control?

• a.Long nails help with sectioning and are encouraged
• b.Cuts on the hands need no covering
• c.Hands should be washed frequently and any cuts covered with a bandage✓
• d.Handwashing is only needed at the start of the day

Clean, well-maintained hands with short nails reduce places for microbes to hide, and open cuts must be covered to protect both barber and client. Frequent handwashing throughout the day is a core infection-control habit.CCR Title 16 §979

Which is the correct order of the decontamination process for a reusable metal implement?

• a.Clean, then disinfect, then store dry in a covered container✓
• b.Disinfect, then clean, then leave wet on the counter
• c.Store, then clean, then use
• d.Rinse only, then reuse immediately

The proper sequence is to first clean the tool to remove debris, then disinfect it for the full contact time, and finally store it dry in a clean covered container. Skipping the cleaning step or storing tools wet undermines the whole process.CCR Title 16 §979

Why must a barber never use a shaving brush or styptic pencil communally on multiple clients?

• a.They are too expensive
• b.They are hard to store
• c.They dull too quickly
• d.They can transfer blood and microbes from client to client✓

Shared items that contact skin or minor nicks, such as a styptic pencil, can carry blood and pathogens between clients. Barbers should use single-use styptic products such as powder or liquid applied with a disposable applicator.CCR Title 16 §979
