This site provides a discussion of the use of the word accident in connection with safety, which I found quite interesting, but it does not provide an all-purpose alternative to using the term. Rather, it advocates its use.
Is the term "accident" still acceptable?
There is a move away from calling vehicle collisions accidents, as although they may happen by accident – that is, not (usually) on purpose –accident does not really describe what has occurred. For vehicles –
Collisions, car wrecks, prangs?
Maybe consider "Artificial accidents" to be:
Unforeseen events? Preventable events? Unintentional occurrences?
As per Merriam-Webster an accident is:
a: an unforeseen and unplanned event or circumstance
Their meeting was an accident.
b: lack of intention or necessity: chance
They met by accident rather than by design.
2 a: an unfortunate event resulting, especially from carelessness or ignorance He was involved in a traffic accident.
This response is not intended to be definitive, as I don't think there is a term that applies which really covers what is being sought. However, I found the question interesting in that the word the commonly used for a traffic mishap (aka accident) is undergoing a change in some jurisdictions/areas.
