Which term refers to an injury resulting from a work-related accident or exposure involving a single incident?

The term that accurately describes an injury resulting from a work-related accident or exposure involving a single incident is "occupational injury." This term specifically refers to physical injuries that employees sustain while performing their job duties or as a direct result of a work-related incident, such as a slip and fall, a machinery accident, or an exposure to hazardous conditions that occurs all at once, rather than developing over time.

In contrast, occupational health refers more broadly to the overall well-being of employees in relation to their work environment and includes prevention of work-related illnesses and injuries. Occupational illness, on the other hand, is typically used to describe conditions that develop over time due to prolonged exposure to harmful substances or environments, such as asbestosis from asbestos exposure or repetitive strain injuries from repetitive tasks. Occupational risk denotes the potential hazards that can cause injury or illness in a work setting but does not specifically refer to the injuries themselves. Therefore, "occupational injury" is the most precise term for a single, immediate incident resulting in injury at work.
