I just pulled out every dictionary we have here and several online ones.

Every definition I found states in one way or another that Accidents usually can be prevented.

"2 a: an unfortunate event resulting especially from carelessness or ignoranc"

"It implies a generally negative probabilistic outcome which may have been avoided or prevented had circumstances leading up to the accident been recognized, and acted upon, prior to its occurrence."

The terms accident and negligence are not mutually exclusive. Just because it is and accident doesn't mean it is not negligence.

Yes I think each of these circumstances were preventable and probably negligent.
