Health, Safety, and Infection Control Flashcards

A client's pet has had an accident on a carpet. After removing the solid waste, what is the correct disinfection approach for the remaining contaminated area?

Answer: Apply an enzyme-based cleaner first to break down organic matter, then disinfect

Enzyme cleaners break down the proteins in organic waste before disinfection, making the subsequent disinfectant more effective and eliminating odor-causing compounds.

What is the primary purpose of using color-coded cleaning cloths in a professional residential cleaning system?

Answer: To prevent cross-contamination between different areas such as bathrooms and kitchens

Color-coding assigns specific cloth colors to specific zones (e.g., red for toilets, blue for general surfaces), ensuring bacteria from high-contamination areas are never spread to food-prep areas.

Which of the following is a common sign of ergonomic injury risk for residential cleaning professionals?

Answer: Repeated overhead reaching, twisting at the waist, and prolonged kneeling

Repetitive overhead reaching, spinal twisting, and sustained awkward postures are the leading ergonomic risk factors for musculoskeletal injuries in cleaning professionals.

When is it appropriate for a residential cleaner to enter a room that was just fumigated or treated with a pest control chemical?

Answer: Only after the re-entry interval stated on the pesticide label has passed

Pesticide labels are legal documents under FIFRA; the re-entry interval (REI) specifies the minimum wait time required for safety before anyone re-enters a treated area.

A cleaning professional develops a persistent dry cough, watery eyes, and skin rash that consistently appear while working. These symptoms most likely indicate:

Answer: Occupational chemical sensitivity or allergic reaction to cleaning products

Recurring respiratory and skin symptoms that appear during work exposure to cleaning chemicals and improve during days off are classic indicators of occupational chemical sensitization.

What is the key difference between sanitizing and disinfecting a surface?

Answer: Disinfecting kills a broader spectrum of pathogens to higher levels than sanitizing

Disinfecting destroys or irreversibly inactivates a wider range of pathogens to a greater log-reduction level than sanitizing, which only reduces microbial counts to safe levels.

Which practice best prevents the spread of norovirus in a residential setting after an occupant has been ill?

Answer: Disinfecting all high-touch surfaces with an EPA-registered disinfectant listed for norovirus (non-enveloped virus)

Norovirus is a non-enveloped virus that is resistant to many disinfectants; only EPA-registered products specifically listed for norovirus on their label will reliably inactivate it.
