What item is used to protect against splashes or sparks at the midsection?

The correct answer is aprons. Aprons are specifically designed to protect the body, particularly the midsection, from splashes, sparks, and other debris encountered during various activities, such as welding, cooking, or chemical handling. The material of the apron, often made from durable and sometimes heat-resistant materials, serves as a barrier that helps prevent burns, spills, and contaminants from coming into contact with clothing and skin.

While overalls cover a larger area and may offer protection from cuts, dirt, and some splashes, they do not provide the targeted protection at the midsection that aprons do. Chest waders are primarily used for activities involving water and are designed to keep the wearer dry rather than provide splash or spark protection. Safety vests are generally designed for visibility and are used in environments where being seen is critical, such as construction sites, and do not serve the purpose of protecting against splashes or sparks.
