What should be avoided in pedestrian walkway areas that need to be cleanable?

In pedestrian walkway areas that require cleanliness, it is crucial to avoid anything that could hinder cleaning efforts or create safety hazards. The correct answer highlights the necessity of maintaining clear and unobstructed pathways. Decorative mats, while they may add aesthetic appeal, can trap dirt and debris, making it difficult to maintain a clean environment. They can also pose slipping hazards, particularly when wet.

Moreover, mats might lift or curl at the edges over time, creating tripping hazards for pedestrians. For walkways where hygiene and safety are priorities, smoother and more easily cleanable surfaces are preferred to ensure a safe passage free from impediments. Hence, while added traction is beneficial for safety, it is the inclusion of decorative features like mats that should be avoided in these specific areas.
