In common use, however, ‘accident’ may include the entire interacting circumstantial framework (chance, pre-existing, or uncontrolled dynamically developing conditions; commonplace actions; random time and place; participants; etc.) leading up to, including, and resulting from, the accident's immediate occurrence.

Physical examples include, e.g., unintended collisions or falls, being injured by touching something sharp, hot, or electrical, or ingesting poison. Non-physical examples are, e.g, unintentionally revealing a secret
