What design features of equipment support sanitation and ease of cleaning?

• A. Nonporous surfaces, smooth seams, rounded corners, removable parts for cleaning, accessible drainage, and minimized crevices.
• B. Porous materials and irregular seams.
• C. Fixed, non-removable parts and sharp edges.
• D. Glossy surfaces with visible gaps.

Answer: (A)

Design features that support sanitation focus on preventing places where dirt and microbes can hide and making cleaning thorough and efficient. Nonporous surfaces don’t absorb liquids or microorganisms, so cleaning and sanitizing are more effective. Smooth seams and rounded corners eliminate crevices where residue can accumulate. Removable parts allow disassembly so every surface can be cleaned and sanitized. Accessible drainage prevents standing water, which can harbor bacteria. By minimizing crevices, there are fewer hiding spots for dirt and organisms.

Porous materials and irregular seams can trap moisture and debris, making them hard to clean. Fixed, non-removable parts and sharp edges create niches and injuries and are harder to sanitize. Glossy surfaces aren’t the issue themselves, but visible gaps and joints point to spaces that can collect residue and be difficult to sanitize.
