An accident is a specific, identifiable, unexpected, unusual and unintended external event which occurs in a particular time and place, without apparent cause but with marked effects. 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.
