RCS Health, Safety, and Infection Control 3 — Questions and Answers
Question 1: A residential cleaner finds a used hypodermic needle while cleaning a client's bathroom. What is the safest course of action?
- Pick it up with gloved hands and place it in the regular trash
- Use tongs to place it in a puncture-resistant sharps container (Correct answer)
- Leave it in place and clean around it
- Flush it down the toilet
Correct answer: Use tongs to place it in a puncture-resistant sharps container
Used needles must be handled without direct contact using a mechanical aid and disposed of in an approved sharps container to prevent needlestick injuries and disease transmission.
Question 2: What is the correct dilution ratio for a standard household bleach solution used to disinfect surfaces against most common pathogens, per CDC guidelines?
- 1 cup bleach per 1 gallon of water
- 1/3 cup bleach per 1 gallon of water (Correct answer)
- 1 tablespoon bleach per 1 gallon of water
- Undiluted bleach applied directly
Correct answer: 1/3 cup bleach per 1 gallon of water
The CDC recommends approximately 1/3 cup (about 5 tablespoons) of 5.25–8.25% sodium hypochlorite bleach per gallon of water for general surface disinfection.
Question 3: Which personal protective equipment (PPE) is specifically recommended when vacuuming heavily dusty areas or during dry dusting in a home?
- Chemical splash goggles
- N95 or P100 particulate respirator mask (Correct answer)
- Full-face shield
- Hearing protection
Correct answer: N95 or P100 particulate respirator mask
An N95 or P100 respirator filters fine airborne particles, protecting cleaners from inhaling dust, mold spores, and allergens stirred up during dry cleaning tasks.
Question 4: When should a cleaning professional change their cleaning cloths or microfiber towels while cleaning a home?
- Only at the end of the cleaning session
- Only when visibly soiled with heavy grime
- Between rooms or surfaces to prevent cross-contamination (Correct answer)
- Only after cleaning the bathroom
Correct answer: Between rooms or surfaces to prevent cross-contamination
Changing cloths between rooms and between different surface types prevents transferring bacteria and pathogens from contaminated areas (like bathrooms) to lower-risk areas (like kitchens).
Question 5: What does bloodborne pathogen training teach cleaning professionals to assume about every client's blood or body fluids?
- Only visibly infected materials are hazardous
- All blood and body fluids should be treated as potentially infectious (Universal Precautions) (Correct answer)
- Blood is only hazardous if the client has a known illness
- Body fluids other than blood are safe to handle without PPE
Correct answer: All blood and body fluids should be treated as potentially infectious (Universal Precautions)
Universal Precautions, established by OSHA and CDC, require treating all human blood and certain body fluids as infectious regardless of the client's known health status.
Question 6: A cleaning professional notices visible mold growth on a bathroom ceiling. What should they do before attempting to clean it?
- Scrub it dry with a stiff brush immediately
- Wet it with water first to prevent mold spore dispersal, then use appropriate cleaner (Correct answer)
- Use a leaf blower to remove loose mold
- Leave it and inform the client it requires professional remediation only
Correct answer: Wet it with water first to prevent mold spore dispersal, then use appropriate cleaner
Wetting moldy surfaces before cleaning reduces the release of airborne spores, protecting both the cleaner and the home's occupants from respiratory exposure.
Question 7: Which of the following cleaning chemicals should NEVER be stored in a hot car or near heat sources?
- Microfiber cloths
- Aerosol spray disinfectants and flammable solvents (Correct answer)
- Distilled white vinegar
- Baking soda
Correct answer: Aerosol spray disinfectants and flammable solvents
Aerosol cans can explode under high heat and flammable solvents have low flash points, making heat exposure extremely dangerous for these products.
