What areas surrounding urinals for public or semi-public use must be finished as non-absorbent?

1. A. Floor areas only

2. B. Floor and ceiling areas

3. C. Floor, wall, and ceiling areas

4. D. Wall areas only

The correct answer is: C. Floor, wall, and ceiling areas

The correct choice indicates that the floor, wall, and ceiling areas surrounding urinals for public or semi-public use must be finished as non-absorbent. This requirement is rooted in health and sanitation regulations aimed at maintaining a hygienic environment in restrooms. Non-absorbent surfaces prevent the absorption of liquids, which can harbor bacteria and create unsanitary conditions. By ensuring that all three areas—the floor, walls, and ceiling—are finished with non-absorbent materials, there is a reduction in the likelihood of moisture retention, which can lead to mold, mildew, and other health hazards. It also facilitates easier cleaning and maintenance, which is particularly important in high-traffic public facilities. In public or semi-public restrooms, where there is a higher risk of spills and splashes, the comprehensive coverage of non-absorbent surfaces helps promote safety and cleanliness, making it an essential consideration in plumbing and building codes.
