Which classification would be used for a mishap that causes no injuries and not requiring aid?

The classification for a mishap that causes no injuries and does not require aid is Class D. This classification typically covers incidents that are classified as minor accidents with minimal impact, meaning they do not lead to any injuries and thus, little to no immediate medical attention is necessary. Class D incidents often involve property damage of an insubstantial nature or minor equipment failures that do not pose significant risks or costs to operations.

In contrast, other classifications denote more severe outcomes; for instance, Class A and Class B typically involve significant injuries or damages that warrant formal reporting and might require investigation, with Class A being the most serious involving loss of life or substantial property damage, and Class B indicating serious incidents with considerable impacts. Class C generally covers mishaps that involve non-serious injuries or damages that require some form of medical attention but are not life-threatening. Understanding these classifications helps ensure appropriate responses and resource allocation for mishap management within the Air Force.
