Which physical hazard could result from inadequate maintenance in the kitchen?

The correct choice highlights the significant risk of metal shards as a physical hazard stemming from inadequate maintenance in the kitchen. When kitchen equipment, such as knives, slicers, or machinery, is not properly maintained, it can lead to deterioration or malfunction. For instance, equipment can break down and release sharp metal pieces, posing a serious risk of injury to kitchen staff and potential contamination of food products.

This scenario emphasizes the importance of regular inspection and maintenance of all kitchen tools and machinery to ensure they remain safe for use. By addressing physical hazards like metal shards, operations can enhance food safety and protect the health of both employees and customers.

In the context of the other choices: wet floors can lead to slips and falls; chemical spills can result from improper handling of cleaning supplies; and poor employee training relates to operational safety and hygiene rather than a direct physical hazard. While all these elements are critical for overall kitchen safety, the specific risk of metal shards directly correlates to equipment maintenance and poses a direct threat to physical safety in the kitchen environment.
