Under what condition must floors contain drains in a funeral establishment?

In a funeral establishment, the requirement for floors to contain drains is fundamentally linked to their practicality and hygiene. Floors must have drains if they are subject to cleaning by flooding, as this facilitates the efficient removal of water and waste, thus helping to maintain sanitary conditions. Funeral establishments often engage in cleaning processes that may involve significant amounts of water, either for cleaning surfaces or for preparing remains, making proper drainage essential to prevent standing water, which could lead to safety hazards and hygiene issues.

The need for drainage is specifically tied to functionality and not to aesthetics or arbitrary measurements of space. While materials like wood or factors like space size can contribute to other aspects of building design, they do not inherently necessitate the inclusion of drains. The primary concern in funeral establishments is cleanliness and operational efficiency, which is why draining capabilities must be present when floods or extensive cleaning methods are anticipated.
