Drains in gutters in public shower rooms shall be spaced not more than ___ apart.

The correct answer regarding the spacing of drains in gutters in public shower rooms indicates that they should be spaced no more than 4.90 meters apart. This specification is based on sanitation and design standards aimed at ensuring effective drainage in facilities frequently exposed to large amounts of water, such as public shower rooms. Proper drainage is crucial in preventing water accumulation, which can lead to hygiene issues and facilitate the growth of mold and bacteria.

The spacing requirement of 4.90 meters ensures that any water that may overflow or splatter is quickly channeled away, minimizing the risk of slips and falls, and maintaining a hygienic environment. This measurement often takes into account both the volume of water generated during showers and the capability of the drain system to handle that flow, reinforcing the importance of adhering to standards for public safety and health.

Other options provided might suggest different distances for spacing drains, which may not align with the established standards for effective drainage in public shower facilities. Understanding these specifications is essential for anyone involved in the design, installation, and sanitation management of such spaces.
