20 Facilities, Sanitation & Pests Practice Questions & Answers

1. 1. A manager sees a cook spray sanitizer onto a prep table that still has visible grease and food debris, wipe it once, and begin portioning. Why does this fail to make the surface safe?

   • A.Sanitizer must be warmed first, so a cold spray cannot work.
   • B.Sanitizer works only on stainless steel, not on other surfaces.
   • C.Soil shields and inactivates the sanitizer, so pathogens survive.✓ Answer
   • D.Sanitizing destroys spores only, so bacteria are left behind.

   Cleaning and sanitizing are two separate operations that must happen in that order. Organic soil physically shields microorganisms and chemically ties up the active ingredient, so a sanitizer applied to a dirty surface is used up before it can reduce pathogens to safe levels. The surface must be washed and rinsed first, then sanitized, and the manager should retrain the cook on the sequence.

2. 2. A manager is retraining staff on manual warewashing at the three-compartment sink. Which description of the process is correct?

   • A.Wash, rinse off detergent residue, sanitize, then air dry.✓ Answer
   • B.Wash, sanitize, rinse the sanitizer off, then dry with towels.
   • C.Wash with detergent and sanitizer mixed, rinse, then towel dry.
   • D.Rinse, wash, sanitize, then stack items wet to save counter room.

   The middle compartment exists to rinse away detergent and loosened soil, because carryover detergent neutralizes the sanitizer in the third compartment and weakens the solution below its required strength. Items are then immersed in sanitizer and must be allowed to air dry, since towel drying can recontaminate a surface that was just sanitized.

3. 3. A manager finds that the dish room is using a quaternary ammonium sanitizer but checking the solution with chlorine test strips. What is the correct response?

   • A.Stop testing and judge strength by the smell of the water.
   • B.Keep the strips and double the dose to offset the error.
   • C.Accept the strips, since sanitizer strips read every chemical.
   • D.Provide a test kit made for the sanitizer actually in use.✓ Answer

   A test kit or device must correspond to the sanitizer being used; strips for one chemistry give a meaningless reading on another, so the operation would have no evidence that the solution is within the range on the product label. Concentration has to be measured, not estimated by smell, color or feel, and the manager should also set a testing frequency and record the results.

4. 4. The label of an operation's chemical sanitizer states a minimum solution temperature and a concentration range. During a check the sanitizer water is well below that minimum temperature. What should the person in charge conclude?

   • A.The solution may not sanitize even at the right concentration.✓ Answer
   • B.Cold water concentrates the chemical, making it stronger.
   • C.Temperature applies to heat sanitizing, not to chemicals.
   • D.The cold water is acceptable as long as the contact time is shortened.

   Chemical sanitizing works only when concentration, contact time, solution temperature, water hardness and pH are all within the range the product is registered for; these factors interact, so a solution that is too cold loses activity even when the test strip shows the right concentration. Shortening contact time makes it worse, not better. The corrective action is to bring the water temperature into the labeled range and retest before using the sink.

5. 5. An operation replaces chemical sanitizing with a high-temperature dish machine. How should the manager verify that items are actually being sanitized?

   • A.Confirm the detergent injector draws chemical on every cycle.
   • B.Read the gauge on the machine door panel at the start of each shift.
   • C.Check that the racks are too hot to touch as they come out.
   • D.Measure utensil surface temperature with a heat-sensitive device.✓ Answer

   In hot water mechanical warewashing the sanitizing step depends on the temperature the utensil surface actually reaches, which is what an irreversible registering temperature indicator run through the machine measures. A door gauge reports water temperature at the machine, not at the dish, and it can read correctly while low volume, worn wash arms or overloaded racks keep the surface from ever getting hot enough.

6. 6. A guest vomits near a self-service beverage counter. After the visible soil is cleaned up, what must be done to the affected food-contact surfaces?

   • A.Apply the usual sanitizer at double strength and let it air dry.
   • B.Apply a disinfectant per its label, then rinse with potable water.✓ Answer
   • C.Wash twice with hot detergent water, which removes the virus.
   • D.Apply a disinfectant and leave the residue in place to keep working.

   Routine sanitizers are not effective against the pathogens shed in vomit, feces and blood, so surfaces contaminated with bodily fluids, and surfaces involved in an outbreak or other imminent health hazard, must be disinfected rather than merely sanitized. The disinfectant is used exactly as its registered label directs, and because it is not a food-contact-safe residue, a food-contact surface must be rinsed with potable water afterward unless the label states otherwise.

7. 7. A slicer has been used continuously on ready-to-eat deli meats since 9:00 a.m. and is still running at 1:30 p.m. The operation's procedure requires food-contact surfaces in continuous use with TCS food to be cleaned and sanitized at least every 4 hours. What should the manager do?

   • A.Wait for the rush to end, then clean it at a slow time.
   • B.Wipe the blade with a sanitizer cloth and keep going.
   • C.Take the slicer down now and clean and sanitize it.✓ Answer
   • D.Leave it, since the meat stayed at a safe temperature.

   The interval set by the operation's own procedure ran out at 1:00 p.m., so the equipment is already past due and must be taken out of service, disassembled, cleaned and sanitized before it is used again. Wiping the blade in place is neither cleaning nor sanitizing, and correct product temperature does not stop the soil and bacteria that build up on a food-contact surface during hours of continuous use.

8. 8. A manager keeps a master cleaning schedule stating what is cleaned, by whom, when, and with what. What best shows the schedule is being followed?

   • A.Spot-checking the areas and the signed records, then fixing gaps.✓ Answer
   • B.Ordering enough chemicals each month to cover the listed tasks.
   • C.Posting the schedule where the inspector will see it on arrival.
   • D.Having every employee sign the schedule when they are hired.

   A cleaning schedule is a control only if someone verifies it: the person in charge inspects the finished work against the written schedule, compares it with the completed records, and then retrains or reassigns when tasks are being skipped or signed off without being done. Buying supplies, collecting signatures at hire and posting the document create paperwork but confirm nothing about the condition of the facility.

9. 9. During a self-inspection of the chemical storage area, which finding must the manager correct IMMEDIATELY?

   • A.Detergent is stored on a shelf below the single-service lids.
   • B.An unlabeled spray bottle of cleaner sits above a bin of flour.✓ Answer
   • C.Sanitizer buckets sit on a shelf beside the janitorial sink.
   • D.A mop bucket is stored empty and inverted on the janitor closet floor.

   A working container filled from a bulk supply must be marked with the common name of the material, and poisonous or toxic materials must be stored where they cannot contaminate food, equipment, utensils, linens or single-service items — which means below or away from them, never above. An unlabeled cleaner over open flour is both a labeling violation and a chemical contamination hazard; the other three conditions are acceptable storage.

10. 10. Why is an air gap considered the only fully reliable protection against backflow?

    • A.It holds steady pressure in the line so water cannot reverse course.
    • B.It is an open space that no failure or pressure change can bridge.✓ Answer
    • C.It filters any water that tries to reenter the potable supply line.
    • D.It relies on a spring-loaded check valve that shuts when pressure drops.

    An air gap is a physical vertical separation between the water supply outlet and the flood rim of the fixture or equipment it fills, so there is simply no continuous path for contaminated water to travel back up the line. Mechanical backflow preventers such as vacuum breakers work only while their moving parts seal properly, which is why they must be tested and maintained, while an air gap cannot fail as long as no one lowers a hose or drain line into the receiving vessel.

11. 11. A hose is left on the mop sink faucet with its end lying in a full mop bucket. A water main break drops building pressure. What hazard does this create?

    • A.The bucket can overflow and send mop water to the floor drain.
    • B.The hose can freeze and split, flooding the janitorial closet.
    • C.Back-pressure can push potable water out through the sink drain.
    • D.Back-siphonage can draw the mop water into the potable supply.✓ Answer

    The submerged hose end is a cross-connection: a physical link between the potable supply and contaminated water. Backflow is any reverse flow through such a link; when it is caused by negative pressure in the supply line, as a main break produces, it is called back-siphonage, and the dirty water is pulled into the drinking water system. Keeping an air gap between the hose end and the flood rim removes the connection entirely.

12. 12. In the prep area the only handwashing sink holds a stack of clean pans and a case of produce blocks the approach. What should the manager do FIRST?

    • A.Leave it for now and remind staff to use the dish room sink.
    • B.Move the pans and send staff to the prep sink to wash hands.
    • C.Clear the sink and the approach so hands can be washed there.✓ Answer
    • D.Allow hand sanitizer at the station until the shift is over.

    A handwashing sink must be kept accessible at all times and may be used for nothing but handwashing, because handwashing is the main barrier against fecal-oral transmission and staff will skip it if the sink is blocked, in use as storage, or far from where they work. Sending staff to a food preparation sink creates a contamination route, and hand antiseptic is only a supplement to washing, never a replacement.

13. 13. During service the operation loses water pressure and the authority issues a boil-water advisory. What must the person in charge do?

    • A.Switch to bottled water and keep every operation running as usual.
    • B.Finish service and report the outage at the next inspection.
    • C.Keep cooking but suspend handwashing until pressure returns.
    • D.Stop the affected operations at once and notify the regulatory authority.✓ Answer

    Water must come from an approved source and be under pressure in sufficient quantity for the operation; losing it, or being placed under a boil-water advisory, is an imminent health hazard because handwashing, warewashing, ice and food preparation all depend on it. The operation ceases the affected activities immediately, notifies the regulatory authority, and resumes only when the authority approves.

14. 14. A contractor offers to save space by connecting a food prep sink's drain line directly to the sewer line. Why should the manager refuse?

    • A.A direct connection makes the sink drain far too slowly.
    • B.A direct connection needs a larger grease interceptor.
    • C.A direct connection lets sewage back up into the sink.✓ Answer
    • D.A direct connection voids the equipment's factory warranty.

    Sinks that hold food, warewashing machines, ice bins and similar equipment must drain through an indirect waste line with an air gap or air break, so that a blocked or surcharged sewer discharges to the floor drain instead of rising into equipment that touches food. Sewage backing up into the establishment is an imminent health hazard: operations stop and the regulatory authority is notified.

15. 15. Walking the kitchen, which condition must the manager correct IMMEDIATELY?

    • A.The vent hood filters were cleaned during last night's closing.
    • B.A coved floor-to-wall base is scuffed beside the mixer.
    • C.A bare unshielded bulb hangs over the open prep table.✓ Answer
    • D.Dry storage has smooth washable ceiling panels overhead.

    Lamps over exposed food, clean equipment, utensils and single-service articles must be shielded, coated or otherwise shatter-resistant, because a bulb that breaks over open food scatters glass that cannot be removed and forces the food to be discarded. A scuffed cove base, smooth washable ceiling panels and freshly cleaned hood filters are all acceptable conditions.

16. 16. A heavy floor-mounted mixer bearing the mark of an accredited certification program is being installed. What makes the installation cleanable?

    • A.Standing it on a rubber mat lifted out and hosed off weekly.
    • B.Sealing it to the floor, or raising it on legs to clean underneath.✓ Answer
    • C.Setting it on the floor and caulking only along the back edge.
    • D.Pushing it against the wall so nothing can fall behind it.

    Third-party certification tells the buyer the equipment was designed and built to be cleanable, but the operator is responsible for installing it that way. Floor-mounted equipment that is not easily movable must be either sealed to the floor or elevated on legs that leave enough clearance to clean under and behind it, and fixed equipment must likewise be spaced away from walls and adjoining units or sealed to them so soil cannot collect in an unreachable gap.

17. 17. A manager is replacing worn smallwares. Which item is acceptable as a food-contact surface?

    • A.A copper bowl used for whisking a vinegar salad dressing.
    • B.A soft pine board that is sanded whenever it gets grooved.
    • C.A cracked plastic storage tub kept only for holding cooled produce.
    • D.A hard maple cutting board that is smooth and free of cracks.✓ Answer

    Multiuse food-contact surfaces must be smooth, nonabsorbent, durable, corrosion-resistant, nontoxic and free of breaks, cracks and open seams, because cracks and absorbent material hold soil and moisture where detergent and sanitizer cannot reach, so the surface can never be verified clean. Hard maple or an equivalently hard, close-grained wood is the exception allowed for cutting surfaces, while soft open-grained wood is not, and copper must not touch acidic food such as a vinegar dressing.

18. 18. What is the MOST important part of an operation's integrated pest management program?

    • A.Spraying residual insecticide along the baseboards every week.
    • B.Setting glue boards along the walls of the dry storage room.
    • C.Scheduling a fogging treatment before each holiday season.
    • D.Denying pests entry, food, water and places to hide.✓ Answer

    Integrated pest management is built on prevention: keep pests out with tight-fitting self-closing doors, screening and sealed gaps around pipes, floors and walls; take away food, water and harborage by cleaning spills, storing product off the floor and away from walls, and controlling refuse; and inspect incoming deliveries and the premises for evidence of pests. Traps and pesticides applied by a licensed pest control operator support that program but cannot substitute for it, because pests will keep returning to a building that still feeds and shelters them.

19. 19. A cook reports droppings and gnaw marks on a flour sack in dry storage. What should the manager do?

    • A.Move the untouched sacks to another shelf and keep watching.
    • B.Buy an over-the-counter pesticide and treat the room tonight.
    • C.Discard the affected food and call a licensed pest operator.✓ Answer
    • D.Wipe the shelving with sanitizer and reopen after service.

    Droppings, gnaw marks, grease or rub marks, egg casings, nesting material and a stale oily odor are evidence of an infestation, and food that pests have reached is contaminated and must be thrown out rather than moved or salvaged. Control belongs to a licensed pest control operator, who selects and applies products according to their registered label; staff applying retail pesticides in a food area risk contaminating food and equipment and can drive the pests deeper into the building.

20. 20. At the outdoor waste area, which condition must be corrected?

    • A.The container sits on a sloped concrete pad by the door.
    • B.A locked fence with a self-closing gate encloses the pad.
    • C.The lids are propped open on a full waste container.✓ Answer
    • D.The drain plug is in place and the container is closed.

    Receptacles and waste handling units kept outside must have tight-fitting lids or doors and be kept closed, because an open container feeds and shelters rodents, insects and birds right beside the building, generates odors, and fills with rain that leaches out onto the ground. The storage surface being smooth, durable, nonabsorbent concrete sloped to drain, the drain plug being in place and the area being fenced are all acceptable, so the open lids are the finding to correct.
