Any use of the word "accident" in any context. "Unintended event" does not equate to "accident."
Struck by Lightning? That's an accident. In most cases there ain't squat that you could have done to prevent it, and you had nothing to do with the cause and effect. an unintended discharge, striking an unintended object, a miss, drop, or any other thing that wasn't meant to happen but did anyway means that did something that you could have prevented by strapping your holster, use of a safety, line of sight awareness, awareness of load status, etc, there is practically no such thing as an accident in any aspect of life. you can't accidentally cut your finger in the kitchen; nobody put your finger under that cleaver but yourself, and saying "gee, it slipped" is just an excuse.
