CMI Best Practices in Cleaning Procedures 5

Question 1

What is the main advantage of using color-coded cleaning cloths and mop heads in a facility?

Accepted Answer

They prevent cross-contamination by designating specific tools for specific areas

Answer

Color-coding systems assign specific colors to specific areas (e.g., red for restrooms, blue for general areas) to prevent cross-contamination between zones.

Question 2

A custodian finds that a disinfectant cleaner's solution has been sitting in a bucket for 6 hours. What should be done?

Accepted Answer

Discard the solution and prepare a fresh batch

Answer

Most disinfectant solutions lose their effectiveness over time, especially when diluted; fresh solution should be prepared for each cleaning session.

Question 3

When cleaning restroom floors near urinals and toilets, which technique reduces exposure to aerosolized pathogens?

Accepted Answer

Wet mop with disinfectant using gentle, low-agitation strokes

Answer

Gentle low-agitation mopping minimizes aerosolizing contaminated water droplets that could be inhaled or land on nearby surfaces.

Question 4

Which action is MOST important after completing cleaning tasks in an isolation room?

Accepted Answer

Remove PPE outside the room and dispose of or decontaminate properly

Answer

PPE must be carefully removed (doffed) in the correct order outside or at the threshold of the isolation room to prevent self-contamination.

Question 5

A floor finish appears yellowed and dull despite regular spray buffing. What is the MOST likely cause?

Accepted Answer

Too many finish coats have been applied without stripping

Answer

Buildup of old finish layers causes yellowing and loss of clarity; a full strip and recoat cycle restores appearance.
