How often should a PT sanitize the walls and ceilings of an anteroom?

• A. Daily
• B. Weekly
• C. Monthly
• D. Biweekly

Answer: (B)

Keeping the anteroom clean relies on matching cleaning frequency to how surfaces are used and how quickly they collect dust or contaminants. Walls and ceilings aren’t touched during routine work, but dust and other particles can settle on them over time. Cleaning these surfaces on a weekly basis helps control buildup and maintain air quality without the overhead of daily scrubbing. Daily cleaning is reserved for surfaces that are touched or likely to become contaminated more quickly, like floors or workbenches. Monthly would allow more dust and residues to accumulate than is desirable in a cleanroom-adjacent area, and biweekly is less common than a weekly schedule. So, weekly cleaning of walls and ceilings is the most appropriate routine.
