Which two types of urinals are most commonly found on Air Force (AF) installations?

The correct choice identifies the two types of urinals that are most commonly found on Air Force installations as wall-hung and pedestal. This is due to the practical considerations of each design.

Wall-hung urinals are typically mounted directly onto the wall, which allows for easier installation and maintenance. Their design facilitates easier cleaning under and around them, and they generally take up less space, making them suitable for various restroom layouts. These features align well with the requirements of military facilities where efficiency and cleanliness are paramount.

Pedestal urinals, on the other hand, are freestanding units that often have a more traditional appearance. They can accommodate high usage levels, maintaining durability in high-traffic areas such as those commonly found on Air Force bases. This construction also aids in maintenance and can be advantageous in ensuring good hygiene through easier access for cleaning.

While other options may describe types of urinals not typically used in Air Force installations, wall-hung and pedestal urinals offer a combination of durability, efficiency, and practicality that meets the operational needs of military facilities effectively.
