How should floors and drain traps be maintained?

• A. Floors should slope to the drain and drain traps kept filled with liquid.
• B. Floors should slope away from the drain.
• C. Drain traps should be kept dry.
• D. Drains are unnecessary if floors are clean.

Answer: (A)

Maintaining floors and drain traps centers on ensuring proper drainage and blocking sewer gas from entering the space. Floors should be sloped toward the drain so liquids flow efficiently to the drainage system rather than pooling in corners, which can harbor bacteria and create slip hazards. Drain traps must be kept filled with liquid to maintain a continuous water seal that prevents gases from the sewer from escaping into the room. Keeping traps dry would break that seal and allow odors or hazardous gases to come through. Clean floors alone don’t address the need to move liquids to the drain or to block gas entry, so the combination of slope toward the drain and keeping traps filled with liquid is the correct maintenance practice.
